K N O W N B U G S I N S E N D M A I L
The following are bugs or deficiencies in sendmail that we are aware of
but which have not been fixed in the current release. You probably
want to get the most up to date version of this from ftp.sendmail.org
in /pub/sendmail/KNOWNBUGS. For descriptions of bugs that have been
fixed, see the file RELEASE_NOTES (in the root directory of the sendmail
distribution).
This list is not guaranteed to be complete.
* Header values which are too long may be truncated.
If a value of a structured header is longer than 256 (MAXNAME)
characters then it may be truncated during output. For example,
if a single address in the To: header is longer than 256 characters
then it will be truncated which may result in a syntactically
invalid address.
+* Berkeley DB map locking problem with fcntl().
+
+ For Linux the default is to use fcntl() for file locking. However,
+ this does not work with Berkeley DB 5.x and probably later.
+ Switching to flock(), i.e., compile with -DHASFLOCK fixes this
+ (however, the have been problems with flock() on some Linux
+ versions). Alternatively, use CDB or an earlier BDB version.
+
* Delivery to programs that generate too much output may cause problems
If e-mail is delivered to a program which generates too much
output, then sendmail may issue an error:
timeout waiting for input from local during Draining Input
Make sure that the program does not generate output beyond a
status message (corresponding to the exit status). This may
require a wrapper around the actual program to redirect output
to /dev/null.
Such a problem has been reported for bulk_mailer.
* Null bytes are not handled properly in headers.
Sendmail should handle full binary data. As it stands, it handles
all values in the body, but not 0x00 in the header. Changing
this would require a major restructuring of the code -- for
example, almost no C library support could be used to handle
strings.
* Header checks are not called if header value is too long or empty.
If the value of a header is longer than 1250 (MAXNAME + MAXATOM - 6)
characters or it contains a single word longer than 256 (MAXNAME)
characters then no header check is done even if one is configured for
the header.
* Header lines which are too long will be split incorrectly.
Header lines which are longer than 2045 characters will be split
but some characters might be lost. Fix: obey RFC (2)822 and do not
send lines that are longer than 1000 characters.
* milter communication fails if a single header is larger than 64K.
If a single header is larger than 64KB (which is not possible in the
default configuration) then it cannot be transferred in one block to
libmilter and hence the communication fails. This can be avoided by
increasing the constant MILTER_CHUNK_SIZE in
include/libmilter/mfdef.h and recompiling sendmail, libmilter, and
all (statically linked) milters (or by using undocumented compile
time options: _FFR_MAXDATASIZE/_FFR_MDS_NEGOTIATE; you have to
read the source code in order to use these properly).
* Sender addresses whose domain part cause a temporary A record lookup
failure but have a valid MX record will be temporarily rejected in
the default configuration. Solution: fix the DNS at the sender side.
If that's not easy to achieve, possible workarounds are:
- add an entry to the access map:
dom.ain OK
- (only for advanced users) replace
# Resolve map (to check if a host exists in check_mail)
Kresolve host -a<OKR> -T<TEMP>
with
# Resolve map (to check if a host exists in check_mail)
Kcanon host -a<OKR> -T<TEMP>
Kdnsmx dns -R MX -a<OKR> -T<TEMP>
Kresolve sequence dnsmx canon
* Duplicate error messages.
Sometimes identical, duplicate error messages can be generated. As
near as I can tell, this is rare and relatively innocuous.
* Misleading error messages.
If an illegal address is specified on the command line together
with at least one valid address and PostmasterCopy is set, the
DSN does not contain the illegal address, but only the valid
address(es).
* \231 considered harmful.
Header addresses that have the \231 character (and possibly others
in the range \201 - \237) behave in odd and usually unexpected ways.
* AuthRealm for Cyrus SASL may not work as expected. The man page
and the actual usage for sasl_server_new() seem to differ.
Feedback for the "correct" usage is welcome, a patch to match
the description of the man page is in contrib/AuthRealm.p0.
* accept() problem on SVR4.
Apparently, the sendmail daemon loop (doing accept()s on the network)
can get into a weird state on SVR4; it starts logging ``SYSERR:
getrequests: accept: Protocol Error''. The workaround is to kill
and restart the sendmail daemon. We don't have an SVR4 system at
Berkeley that carries more than token mail load, so I can't validate
this. It is likely to be a glitch in the sockets emulation, since
"Protocol Error" is not possible error code with Berkeley TCP/IP.
I've also had someone report the message ``sendmail: accept:
SIOCGPGRP failed errno 22'' on an SVR4 system. This message is
not in the sendmail source code, so I assume it is also a bug
in the sockets emulation. (Errno 22 is EINVAL "Invalid Argument"
on all the systems I have available, including Solaris 2.x.)
Apparently, this problem is due to linking -lc before -lsocket;
if you are having this problem, check your Makefile.
* accept() problem on Linux.
The accept() in sendmail daemon loop can return ETIMEDOUT. An
error is reported to syslog:
Jun 9 17:14:12 hostname sendmail[207]: NOQUEUE: SYSERR(root):
getrequests: accept: Connection timed out
"Connection timed out" is not documented as a valid return from
accept(2) and this was believed to be a bug in the Linux kernel.
Later information from the Linux kernel group states that Linux
2.0 kernels follow RFC1122 while sendmail follows the original BSD
(now POSIX 1003.1g draft) specification. The 2.1.X and later kernels
will follow the POSIX draft.
* Excessive mailing list nesting can run out of file descriptors.
If you have a mailing list that includes lots of other mailing
lists, each of which has a separate owner, you can run out of
file descriptors. Each mailing list with a separate owner uses
one open file descriptor (prior to 8.6.6 it was three open
file descriptors per list). This is particularly egregious if
you have your connection cache set to be large.
* Connection caching breaks if you pass the port number as an argument.
If you have a definition such as:
Mport, P=[IPC], F=kmDFMuX, S=11/31, R=21,
M=2100000, T=DNS/RFC822/SMTP,
A=IPC [127.0.0.1] $h
(i.e., where $h is the port number instead of the host name) the
connection caching code will break because it won't notice that
two messages addressed to different ports should use different
connections.
* ESMTP SIZE underestimates the size of a message
Sendmail makes no allowance for headers that it adds, nor does it
account for the SMTP on-the-wire \r\n expansion. It probably doesn't
allow for 8->7 bit MIME conversions either.
* Client ignores SIZE parameter.
When sendmail acts as client and the server specifies a limit
for the mail size, sendmail will ignore this and try to send the
mail anyway. The server will usually reject the MAIL command
which specifies the size of the message and hence this problem
is not significant.
* Paths to programs being executed and the mode of program files are
not checked. Essentially, the RunProgramInUnsafeDirPath and
RunWritableProgram bits in the DontBlameSendmail option are always
set. This is not a problem if your system is well managed (that is,
if binaries and system directories are mode 755 instead of something
foolish like 777).
* 8-bit data in GECOS field
If the GECOS (personal name) information in the passwd file contains
8-bit characters, those characters can be included in the message
header, which can cause problems when sending SMTP to hosts that
only accept 7-bit characters.
* 8->7 bit MIME conversion
When sendmail is doing 8->7 bit MIME conversions, and the message
contains certain MIME body types that cannot be converted to 7-bit,
sendmail will pass the message as 8-bit.
* 7->8 bit MIME conversion
If a message that is encoded as 7-bit MIME is converted to 8-bit and
that message when decoded is illegal (e.g., because of long lines or
illegal characters), sendmail can produce an illegal message.
* MIME encoded full name phrases in the From: header
If a full name phrase includes characters from MustQuoteChars, sendmail
will quote the entire full name phrase. If MustQuoteChars includes
characters which are not special characters according to STD 11 (RFC
822), this quotation can interfere with MIME encoded full name phrases.
By default, sendmail includes the single quote character (') in
MustQuoteChars even though it is not listed as a special character in
STD 11.
* bestmx map with -z flag truncates the list of MX hosts
A bestmx map configured with the -z flag will truncate the list
of MX hosts. This prevents creation of strings which are too
long for ruleset parsing. This can have an adverse effect on the
relay_based_on_MX feature.
* Saving to ~sender/dead.letter fails if su'ed to root
If ErrorMode is set to print and an error in sending mail occurs,
the normal action is to print a message to the screen and append
the message to a dead.letter file in the sender's home directory.
In the case where the sender is using su to act as root, the file
safety checks prevent sendmail from saving the dead.letter file
because the sender's uid and the current real uid do not match.
* Berkeley DB 2.X race condition with fcntl() locking
There is a race condition for Berkeley DB 2.X databases on
operating systems which use fcntl() style locking, such as
Solaris. Sendmail locks the map before calling db_open() to
prevent others from modifying the map while it is being opened.
Unfortunately, Berkeley DB opens the map, closes it, and then
reopens it. fcntl() locking drops the lock when any file
descriptor pointing to the file is closed, even if it is a
different file descriptor than the one used to initially lock
the file. As a result there is a possibility that entries in a
map might not be found during a map rebuild. As a workaround,
you can use makemap to build a map with a new name and then
"mv" the new db file to replace the old one.
Sleepycat Software has added code to avoid this race condition to
Berkeley DB versions after 2.7.5.
* File open timeouts not available on hard mounted NFS file systems
Since SIGALRM does not interrupt an RPC call for hard mounted
NFS file systems, it is impossible to implement a timeout on a file
open operation. Therefore, while the NFS server is not responding,
attempts to open a file on that server will hang. Systems with
local mail delivery and NFS hard mounted home directories should be
avoided, as attempts to open the forward files could hang.
* Race condition for delivery to set-user-ID files
Sendmail will deliver to a file if the file is owned by the DefaultUser
or has the set-user-ID bit set. Unfortunately, some systems clear that bit
when a file is modified. Sendmail compensates by resetting the file mode
back to it's original settings. Unfortunately, there's still a
permission failure race as sendmail checks the permissions before locking
the file. This is unavoidable as sendmail must verify the file is safe
to open before opening it. A file can not be locked until it is open.
* MAIL_HUB always takes precedence over LOCAL_RELAY
Despite the information in the documentation, MAIL_HUB ($H) will always
be used if set instead of LOCAL_RELAY ($R). This will be fixed in a
future version.

+-----------------------+
| DIRECTORY PERMISSIONS |
+-----------------------+
Sendmail often gets blamed for many problems that are actually the
result of other problems, such as overly permissive modes on directories.
For this reason, sendmail checks the modes on system directories and
files to determine if they can be trusted. For sendmail to run without
complaining, you MUST execute the following command:
chmod go-w / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
chown root / /etc /etc/mail /usr /var /var/spool /var/spool/mqueue
You will probably have to tweak this for your environment (for example,
some systems put the spool directory into /usr/spool instead of
/var/spool). If you set the RunAsUser option in your sendmail.cf, the
/var/spool/mqueue directory will have to be owned by the RunAsUser user.
As a general rule, after you have compiled sendmail, run the command
sendmail -v -bi
to initialize the alias database. If it gives messages such as
WARNING: writable directory /etc
WARNING: writable directory /var/spool/mqueue
then the directories listed have inappropriate write permissions and
should be secured to avoid various possible security attacks.
Beginning with sendmail 8.9, these checks have become more strict to
prevent users from being able to access files they would normally not
be able to read. In particular, .forward and :include: files in unsafe
directory paths (directory paths which are group or world writable) will
no longer be allowed. This would mean that if user joe's home directory
was writable by group staff, sendmail would not use his .forward file.
This behavior can be altered, at the expense of system security, by
setting the DontBlameSendmail option. For example, to allow .forward
files in group writable directories:
O DontBlameSendmail=forwardfileingroupwritabledirpath
Or to allow them in both group and world writable directories:
O DontBlameSendmail=forwardfileinunsafedirpath
Items from these unsafe .forward and :include: files will be marked
as unsafe addresses -- the items can not be deliveries to files or
programs. This behavior can also be altered via DontBlameSendmail:
O DontBlameSendmail=forwardfileinunsafedirpath,
forwardfileinunsafedirpathsafe
The first flag allows the .forward file to be read, the second allows
the items in the file to be marked as safe for file and program
delivery.
Other files affected by this strengthened security include class
files (i.e., Fw /etc/mail/local-host-names), persistent host status files,
and the files specified by the ErrorHeader and HelpFile options. Similar
DontBlameSendmail flags are available for the class, ErrorHeader, and
HelpFile files.
If you have an unsafe configuration of .forward and :include:
files, you can make it safe by finding all such files, and doing
a "chmod go-w $FILE" on each. Also, do a "chmod go-w $DIR" for
each directory in the file's path.
+--------------------------+
| FILE AND MAP PERMISSIONS |
+--------------------------+
Any application which uses either flock() or fcntl() style locking or
other APIs that use one of these locking methods (such as open() with
O_EXLOCK and O_SHLOCK) on files readable by other local untrusted users
may be susceptible to local denial of service attacks.
File locking is used throughout sendmail for a variety of files
including aliases, maps, statistics, and the pid file. Any user who
can open one of these files can prevent sendmail or it's associated
utilities, e.g., makemap or newaliases, from operating properly. This
can also affect sendmail's ability to update status files such as
statistics files. For system which use flock() for file locking, a
user's ability to obtain an exclusive lock prevents other sendmail
processes from reading certain files such as alias or map databases.
A workaround for this problem is to protect all sendmail files such
that they can't be opened by untrusted users. As long as users can
not open a file, they can not lock it. Since queue files should
already have restricted permissions, the only files that need
adjustment are alias, map, statistics, and pid files. These files
should be owned by root or the trusted user specified in the
TrustedUser option. Changing the permissions to be only readable and
writable by that user is sufficient to avoid the denial of service.
For example, depending on the paths you use, these commands would be
used:
chmod 0640 /etc/mail/aliases /etc/mail/aliases.{db,pag,dir}
chmod 0640 /etc/mail/*.{db,pag,dir}
chmod 0640 /etc/mail/statistics /var/log/sendmail.st
chmod 0600 /var/run/sendmail.pid /etc/mail/sendmail.pid
If the permissions 0640 are used, be sure that only trusted users belong
to the group assigned to those files. Otherwise, files should not even
be group readable. As of sendmail 8.12.4, the permissions shown above
are the default permissions for newly created files.
Note that the denial of service on the plain text aliases file
(/etc/mail/aliases) only prevents newaliases from rebuilding the
aliases file. The same is true for the database files on systems which
use fcntl() style locking. Since it does not interfere with normal
operations, sites may chose to leave these files readable. Also, it is
not necessary to protect the text files associated with map databases
as makemap does not lock those files.

doc/op/op.me
The sendmail Installation & Operations Guide. In addition
to the shipped PostScript version, plain text and PDF versions
can be generating using (assuming the required conversion software
is installed on your system, see doc/op/Makefile):
cd doc/op && make op.txt op.pdf
Be warned: on some systems calling make in doc/op/ will cause
errors due to nroff/groff problems. Known problems are:
- running this off on systems with an old version of -me, you
need to add the following macro to the macros:
.de sm
\s-1\\$1\\s0\\$2
..
This sets a word in a smaller pointsize.
- with new groff versions (1.18 seems affected)
GROFF_NO_SGR=1
needs to be set, e.g., in doc/op/Makefile:
ROFF_CMD= GROFF_NO_SGR=1 groff

+-------------------+
| DATABASE ROUTINES |
+-------------------+
IF YOU WANT TO RUN THE NEW BERKELEY DB SOFTWARE: **** DO NOT ****
use the version that was on the Net2 tape -- it has a number of
nefarious bugs that were bad enough when I got them; you shouldn't have
to go through the same thing. Instead, get a new version via the web at
http://www.sleepycat.com/. This software is highly recommended; it gets
rid of several stupid limits, it's much faster, and the interface is
nicer to animals and plants. If the Berkeley DB include files
are installed in a location other than those which your compiler searches,
you will need to provide that directory when building:
./Build -I/path/to/include/directory
If you are using Berkeley DB versions 1.85 or 1.86, you are *strongly*
urged to upgrade to DB version 2 or later, available from
http://www.sleepycat.com/. Berkeley DB versions 1.85 and 1.86 are known to
be broken in various nasty ways (see http://www.sleepycat.com/db.185.html),
and can cause sendmail to dump core. In addition, the newest versions of
gcc and the Solaris compilers perform optimizations in those versions that
may cause fairly random core dumps.
If you have no choice but to use Berkeley DB 1.85 or 1.86, and you are
using both Berkeley DB and files in the UNIX ndbm format, remove ndbm.h
and ndbm.o from the DB library after building it. You should also apply
all of the patches for DB 1.85 and 1.86 found at the Sleepycat web site
(see http://www.sleepycat.com/db.185.html), as they fix some of the known
problems.
If you are using a version of Berkeley DB 2 previous to 2.3.15, and you
are using both Berkeley DB and files in the UNIX ndbm format, remove dbm.o
from the DB library after building it. No other changes are necessary.
If you are using Berkeley DB version 2.3.15 or greater, no changes are
necessary.
The underlying database file formats changed between Berkeley DB versions
1.85 and 1.86, again between DB 1.86 and version 2.0, and finally between
DB 2.X and 3.X. If you are upgrading from one of those versions, you must
recreate your database file(s). Do this by rebuilding all maps with
makemap and rebuilding the alias file with newaliases.
+--------------------+
| HOST NAME SERVICES |
+--------------------+
If you are using NIS or /etc/hosts, it is critical that you
list the long (fully qualified) name somewhere (preferably first) in
the /etc/hosts file used to build the NIS database. For example, the
line should read
128.32.149.68 mastodon.CS.Berkeley.EDU mastodon
**** NOT ****
128.32.149.68 mastodon
If you do not include the long name, sendmail will complain loudly
about ``unable to qualify my own domain name (mastodon) -- using
short name'' and conclude that your canonical name is the short
version and use that in messages. The name "mastodon" doesn't mean
much outside of Berkeley, and so this creates incorrect and unreplyable
messages.
+-------------+
| USE WITH MH |
+-------------+
This version of sendmail notices and reports certain kinds of SMTP
protocol violations that were ignored by older versions. If you
are running MH you may wish to install the patch in contrib/mh.patch
that will prevent these warning reports. This patch also works
with the old version of sendmail, so it's safe to go ahead and
install it.
+----------------+
| USE WITH IDENT |
+----------------+
Sendmail 8 supports the IDENT protocol, as defined by RFC 1413.
Note that the RFC states a client should wait at least 30 seconds
for a response. As of 8.10.0, the default Timeout.ident is 5 seconds
as many sites have adopted the practice of dropping IDENT queries.
This has lead to delays processing mail.
-No ident server is included with this distribution. It is available
-from:
-
- ftp://ftp.lysator.liu.se/pub/ident/servers/
- http://sf.www.lysator.liu.se/~pen/pidentd/
+-------------------------+
| INTEROPERATION PROBLEMS |
+-------------------------+
Microsoft Exchange Server 5.0
We have had a report that ``about 7% of messages from Sendmail
to Exchange were not being delivered with status messages of
"connection reset" and "I/O error".'' Upgrading Exchange from
Version 5.0 to Version 5.5 Service Pack 2 solved this problem.
CommuniGate Pro
CommuniGate Pro 3.2.4 does not accept the AUTH= -parameter on
the MAIL FROM command if the client is not authenticated. Use
define(`confAUTH_OPTIONS', `A')
in .mc file if you have compiled sendmail with Cyrus SASL
and you communicate with CommuniGate Pro servers.
+---------------------+
| DIRECTORY STRUCTURE |
+---------------------+
The structure of this directory tree is:
cf Source for sendmail configuration files. These are
different than what you've seen before. They are a
fairly dramatic rewrite, requiring the new sendmail
(since they use new features).
contrib Some contributed tools to help with sendmail. THESE
ARE NOT SUPPORTED by sendmail -- contact the original
authors if you have problems. (This directory is not
on the 4.4BSD tape.)
devtools Build environment. See devtools/README.
doc Documentation. If you are getting source, read
op.me -- it's long, but worth it.
editmap A program to edit and query maps that have been created
with makemap, e.g., adding and deleting entries.
include Include files used by multiple programs in the distribution.
libsmdb sendmail database library with support for Berkeley DB 1.X,
Berkeley DB 2.X, Berkeley DB 3.X, and NDBM.
libsmutil sendmail utility library with functions used by different
programs.
mail.local The source for the local delivery agent used for 4.4BSD.
THIS IS NOT PART OF SENDMAIL! and may not compile
everywhere, since it depends on some 4.4-isms. Warning:
it does mailbox locking differently than other systems.
mailstats Statistics printing program.
makemap A program that creates the keyed maps used by the $( ... $)
construct in sendmail. It is primitive but effective.
It takes a very simple input format, so you will probably
expect to preprocess must human-convenient formats
using sed scripts before this program will like them.
But it should be functionally complete.
praliases A program to print the map version of the aliases file.
rmail Source for rmail(8). This is used as a delivery
agent for for UUCP, and could presumably be used by
other non-socket oriented mailers. Older versions of
rmail are probably deficient. RMAIL IS NOT PART OF
SENDMAIL!!! The 4.4BSD source is included for you to
look at or try to port to your system. There is no
guarantee it will even compile on your operating system.
smrsh The "sendmail restricted shell", which can be used as
a replacement for /bin/sh in the prog mailer to provide
increased security control. NOT PART OF SENDMAIL!
sendmail Source for the sendmail program itself.
test Some test scripts (currently only for compilation aids).
vacation Source for the vacation program. NOT PART OF SENDMAIL!

SENDMAIL RELEASE NOTES
This listing shows the version of the sendmail binary, the version
of the sendmail configuration files, the date of release, and a
summary of the changes in that release.
+8.17.1/8.17.1 2021/08/17
+ Deprecation notice: due to compatibility problems with some
+ third party code, we plan to finally switch from K&R
+ to ANSI C. If you are using sendmail on a system
+ which does not have a compiler for ANSI C contact us
+ with details as soon as possible so we can determine
+ how to proceed.
+ Experimental support for SMTPUTF8 (EAI, see RFC 6530-6533)
+ is available when using the compile time option USE_EAI
+ (see also devtools/Site/site.config.m4.sample for other
+ required settings) and the cf option SMTPUTF8.
+ If a mail submission via the command line requires
+ the use of SMTPUTF8, e.g., because a header uses UTF-8
+ encoding, but the addresses on the command line are all
+ ASCII, then the new option -U must be used, and
+ the cf option SMTPUTF8 must be set in submit.cf.
+ Please test and provide feedback.
+ Experimental support for SMTP MTA Strict Transport Security
+ (MTA-STS, see RFC 8461) is available when using
+ - the compile time option _FFR_MTA_STS (which requires
+ STARTTLS, MAP_REGEX, SOCKETMAP, and _FFR_TLS_ALTNAMES),
+ - FEATURE(sts), which implicitly sets the cf option
+ StrictTransportSecurity,
+ - postfix-mta-sts-resolver, see
+ https://github.com/Snawoot/postfix-mta-sts-resolver.git
+ New ruleset check_other which is called for all unknown SMTP
+ commands in the server and for commands which do not
+ have specific rulesets, e.g., NOOP and VERB.
+ New ruleset clt_features which can be used to select features
+ in the SMTP client per server. Currently only two
+ flags are available: D/M to disable DANE/MTA-STS,
+ respectively.
+ Avoid leaking session macros for an envelope between
+ delivery attempts to different servers. This problem
+ could have affected check_compat.
+ Avoid leaking actual SMTP replies between delivery attempts
+ to different servers which could cause bogus logging
+ of reply= entries.
+ Change default SMTP reply code for STARTTLS related problems
+ from 403 to 454 to better match the RFCs.
+ Fix a theoretical buffer overflow when encountering an
+ unknown/unsupported socket address family on an
+ operating system where sa_data is larger than 30
+ (the standard is 14). Based on patch by Toomas Soome.
+ Several potential memory leaks and other similar problems
+ (mostly in error handling code) have been fixed.
+ Problems reported by Tomas Korbar of RedHat.
+ Previously the commands GET, POST, CONNECT, or USER terminate
+ a connection immediately only if sent as first command.
+ Now this is also done if any of these is sent directly
+ after STARTTLS or if the 'h' option is set via
+ srv_features.
+ CDB map locking has been changed so a sendmail process which
+ does have a CDB map open does not block an in-place
+ update of the map by makemap. The simple workaround
+ for that problem in earlier versions is to create
+ the map under a different name and then move it
+ into place.
+ On some systems the rejection of a RCPT by a milter could
+ silently fail.
+ CONFIG: New FEATURE(`check_other') to provide a default
+ check_other ruleset.
+ CONFIG: FEATURE(`tls_failures') is deprecated and will be
+ removed in future versions because it has a fundamental
+ problem: it is message oriented but STARTTLS is
+ session oriented. For example, having multiple
+ RCPTs in one envelope for different destinations,
+ with different temporary errors, does not work
+ properly, as the persistent macro applies to all
+ RCPTs and hence implicitly to all destinations (servers).
+ The option TLSFallbacktoClear should be used if needed.
+ MAIL.LOCAL: Enhance some error messages to simplify
+ troubleshooting.
+ Portability:
+ Add support for Darwin 19 & 20.
+ NOTE: File locking using fcntl() does not interoperate
+ with Berkeley DB 5.x (and probably later). Use
+ CDB, flock() (-DHASFLOCK), or an earlier Berkeley
+ DB version. Problem noted by Harald Hannelius.

+ end of the message header.
+ CONTRIB: AuthRealm.p0 has been modified for 8.16.1 by Anne Bennett.
+ CONTRIB: Added cidrexpand -O option for suppressing duplicates from
+ a CIDR expansion that overlaps a later entry and -S option
+ for skipping comments exactly like makemap does.

+ compiling. Fix from Brooks Davis of the FreeBSD
+ project.

8.16.1/8.16.1 2020/07/05
SECURITY: If sendmail tried to reuse an SMTP session which had
already been closed by the server, then the connection
cache could have invalid information about the session.
One possible consequence was that STARTTLS was not
used even if offered. This problem has been fixed
by clearing out all relevant status information
when a closed session is encountered.
OpenSSL versions before 0.9.8 are no longer supported.
OpenSSL version 1.1.0 and 1.1.1 are supported.
Initial support for DANE (see RFC 7672 et.al.) is available if
the compile time option DANE is set. Only TLSA RR 3-1-x
is currently implemented.
New options SSLEngine and SSLEnginePath to support OpenSSL engines.
Note: this feature has so far only been tested with the
"chil" engine; please report problems with other engines
if you encounter any.
New option CRLPath to specify a directory which contains
hashes pointing to certificate revocations files.
Based on patch from Al Smith.
New rulesets tls_srv_features and tls_clt_features which
can return a (semicolon separated) list of TLS related
options, e.g., CipherList, CertFile, KeyFile,
see doc/op/op.me for details.
To automatically handle TLS interoperability problems for outgoing
mail, sendmail can now immediately try a connection again
without STARTTLS after a TLS handshake failure.
This can be configured globally via the option
TLSFallbacktoClear or per session via the 'C' flag
of tls_clt_features.
This also adds the new value "CLEAR" for the macro
{verify}: STARTTLS has been disabled internally for
a clear text delivery attempt.
Apply Timeout.starttls also to the server waiting for the TLS
handshake to begin. Based on patch from Simon Hradecky.
New compile time option TLS_EC to enable the use of elliptic
curve cryptography in STARTTLS (previously available as
_FFR_TLS_EC).
Handle MIME boundaries specified in headers which contain CRLF.
Fix detection of loopback net (it was broken when compiled
with NETINET6) and only set the macros {if_addr_out}
and {if_family_out} if the interface of the outgoing
connection does not belong to the loopback net.
Fix logic to enable a milter to delete a recipient in
DeliveryMode=interactive even if it might be subject
to alias expansion.
Log name of a milter making changes (this was missing for
some functions).
Log the actual reply of a server when an SMTP delivery problem
occurs in a "reply=" field if possible.
Log user= for failed AUTH attempts if possible. Based on
patch from Packet Hack, Jim Hranicky, Kevin A. McGrail,
and Joe Quinn.
Add CDB as map type. Note: CDB is a "Constant DataBase", i.e.,
no changes can be made after it is created, hence it
does not work with vacation(1) nor editmap(8) (except
for query mode).
Fix some memory leaks (mostly in error cases) and properly handle
copied varargs in sm_io_vfprintf(). The issues were found
using Coverity Scan and reported (including patches) by
Ondřej Lysoněk of Red Hat.
Do not override ServerSSLOptions and ClientSSLOptions when they
are specified on the command line. Based on patch from
Hiroki Sato.
Add RFC7505 Null MX support for domains that declare they do not
accept mail.
New compile time option LDAP_NETWORK_TIMEOUT which is set
automatically when LDAPMAP is used and
LDAP_OPT_NETWORK_TIMEOUT is available to enable the
new -c option for LDAP maps to specify the network timeout.
CONFIG: New FEATURE(`tls_session_features') to enable standard
rules for tls_srv_features and tls_clt_features; for
details see cf/README.
CONFIG: New options confSSL_ENGINE and confSSL_ENGINE_PATH
for SSLEngine and SSLEnginePath, respectively.
CONFIG: New options confDANE to enable DANE support.
CONFIG: New option confTLS_FALLBACK_TO_CLEAR for TLSFallbacktoClear.
CONFIG: New extension CITag: for TLS restrictions, see cf/README
for details.
CONFIG: FEATURE(`blacklist_recipients') renamed to
FEATURE(`blocklist_recipients').
CONTRIB: cidrexpand updated to support IPv6 CIDR ranges and to
canonicalize IPv6 addresses; if cidrexpand is used with IPv6
addresses then UseCompressedIPv6Addresses must be disabled.
DOC: The dns map can return multiple values in a single result
if the -z option is used.
DOC: Note to set MustQuoteChars=. due to DKIM signatures.
LIBMILTER: Fix typo in a macro. Patch from Ignacio Goyret
of Alcatel-Lucent.
LIBMILTER: Fix reference in xxfi_negotiate documentation.
Patch from Sven Neuhaus.
LIBMILTER: Fix function name in smfi_addrcpt_par documentation.
Patch from G.W. Haywood.
LIBMILTER: Fix a potential memory leak in smfi_setsymlist().
Patch from Martin Svec.
MAKEMAP: New map type "implicit" refers to the first available type,
i.e., it depends on the compile time options NEWDB, DBM,
and CDB. This can be used in conjunction with the
"implicit" map type in sendmail.cf.
Note: makemap, libsmdb, and sendmail must be compiled
with the same options (and library versions of course).
Portability:
Add support for Darwin 14-18 (Mac OS X 10.x).
New option HAS_GETHOSTBYNAME2: set if your system
supports gethostbyname2(2).
Set SM_CONF_SEM=2 for FreeBSD 12 and later due to
changes in sys/sem.h
On Linux set MAXHOSTNAMELEN (the maximum length
of a FQHN) to 256 if it is less than that value.

8.15.2/8.15.2 2015/07/03
If FEATURE(`nopercenthack') is used then some bogus input triggered
a recursion which was caught and logged as
SYSERR: rewrite: excessive recursion (max 50) ...
Fix based on patch from Ondrej Holas.
DHParameters now by default uses an included 2048 bit prime.
The value 'none' previously caused a log entry claiming
there was an error "cannot read or set DH parameters".
Also note that this option applies to the server side only.
The U= mailer field didn't accept group names containing hyphens,
underbars, or periods. Based on patch from David Gwynne
of the University of Queensland.
CONFIG: Allow connections from IPv6:0:0:0:0:0:0:0:1 to relay again.
Patch from Lars-Johan Liman of Netnod Internet Exchange.
CONFIG: New option UseCompressedIPv6Addresses to select between
compressed and uncompressed IPv6 addresses. The default
value depends on the compile-time option IPV6_FULL:
For 1 the default is False, for 0 it is True, thus
preserving the current behaviour. Based on patch from
John Beck of Oracle.
CONFIG: Account for IPv6 localhost addresses in
FEATURE(`block_bad_helo'). Suggested by Andrey Chernov
from FreeBSD and Robert Scheck from the Fedora Project.
CONFIG: Account for IPv6 localhost addresses in check_mail ruleset.
LIBMILTER: Deal with more invalid protocol data to avoid potential
crashes. Problem noted by Dimitri Kirchner.
LIBMILTER: Allow a milter to specify an empty macro list ("", not
NULL) in smfi_setsymlist() so no macro is sent for the
selected stage.
MAKEMAP: A change to check TrustedUser in fewer cases which was
made in 2013 caused a potential regression when makemap
was run as root (which should not be done anyway).
Note: sendmail often contains options "For Future Releases"
(prefix _FFR_) which might be enabled in a subsequent
version or might simply be removed as they turned out not
to be really useful. These features are usually not
documented but if they are, then the required (FFR)
options are listed in
- doc/op/op.* for rulesets and macros,
- cf/README for mc/cf options.
8.15.1/8.15.1 2014/12/06
SECURITY: Properly set the close-on-exec flag for file descriptors
(except stdin, stdout, and stderr) before executing mailers.
If header rewriting fails due to a temporary map lookup failure,
queue the mail for later retry instead of sending it
without rewriting the header. Note: this is done
while the mail is being sent and hence the transaction
is aborted, which only works for SMTP/LMTP mailers
hence the handling of temporary map failures is
suppressed for other mailers. SMTP/LMTP servers may
complain about aborted transactions when this problem
occurs.
See also "DNS Lookups" in sendmail/TUNING.
Incompatible Change: Use uncompressed IPv6 addresses by default,
i.e., they will not contain "::". For example,
instead of ::1 it will be 0:0:0:0:0:0:0:1. This
permits a zero subnet to have a more specific match,
such as different map entries for IPv6:0:0 vs IPv6:0.
This change requires that configuration data
(including maps, files, classes, custom ruleset,
etc) must use the same format, so make certain such
configuration data is updated before using 8.15.
As a very simple check search for patterns like
'IPv6:[0-9a-fA-F:]*::' and 'IPv6::'. If necessary,
the prior format can be retained by compiling with:
APPENDDEF(`conf_sendmail_ENVDEF', `-DIPV6_FULL=0')
in your devtools/Site/site.config.m4 file.
If debugging is turned on (-d0.14) also print the OpenSSL
versions, both build time and run time
(provided STARTTLS is compiled in).
If a connection to the MTA is dropped by the client before its
hostname can be validated, treat it as "may be forged",
so that the unvalidated hostname is not passed to a
milter in xxfi_connect().
Add a timeout for communication with socket map servers
which can be specified using the -d option.
Add a compile time option HESIOD_ALLOW_NUMERIC_LOGIN to allow
numeric logins even if HESIOD is enabled.
The new option CertFingerprintAlgorithm specifies the finger-
print algorithm (digest) to use for the presented cert.
If the option is not set, md5 is used and the macro
{cert_md5} contains the cert fingerprint.
However, if the option is set, the specified algorithm
(e.g., sha1) is used and the macro {cert_fp} contains
the cert fingerprint.
That is, as long as the option is not set, the behaviour
does not change, but otherwise, {cert_md5} is superseded
by {cert_fp} even if you set CertFingerprintAlgorithm
to md5.
The options ServerSSLOptions and ClientSSLOptions can be used
to set SSL options for the server and client side
respectively. See SSL_CTX_set_options(3) for a list.
Note: this change turns on SSL_OP_NO_SSLv2 and
SSL_OP_NO_TICKET for the client. See doc/op/op.me
for details.
The option CipherList sets the list of ciphers for STARTTLS.
See ciphers(1) for possible values.
Do not log "STARTTLS: internal error: tls_verify_cb: ssl == NULL"
if a CRLFile is in use (and LogLevel is 14 or higher.)
Store a more specific TLS protocol version in ${tls_version}
instead of a generic one, e.g., TLSv1 instead of
TLSv1/SSLv3.
Properly set {client_port} value on little endian machines.
Patch from Kelsey Cummings of Sonic.net.
Per RFC 3848, indicate in the Received: header whether SSL or
SMTP AUTH was negotiated by setting the protocol clause
to ESMTPS, ESMTPA, or ESMTPSA instead of ESMTP.
If the 'C' flag is listed as TLSSrvOptions the requirement for the
TLS server to have a cert is removed. This only works
under very specific circumstances and should only be used
if the consequences are understood, e.g., clients
may not work with a server using this.
The options ClientCertFile, ClientKeyFile, ServerCertFile, and
ServerKeyFile can take a second file name, which must be
separated from the first with a comma (note: do not use
any spaces) to set up a second cert/key pair. This can
be used to have certs of different types, e.g., RSA
and DSA.
A new map type "arpa" is available to reverse an IP (IPv4 or IPv6)
address. It returns the string for the PTR lookup, but
without trailing {ip6,in-addr}.arpa.
New operation mode 'C' just checks the configuration file, e.g.,
sendmail -C new.cf -bC
will perform a basic syntax/consistency check of new.cf.
The mailer flag 'I' is deprecated and will be removed in a
future version.
Allow local (not just TCP) socket connections to the server, e.g.,
O DaemonPortOptions=Family=local, Addr=/var/mta/server.sock
can be used.
If the new option MaxQueueAge is set to a value greater than zero,
entries in the queue will be retried during a queue run
only if the individual retry time has been reached which
is doubled for each attempt. The maximum retry time is
limited by the specified value.
New DontBlameSendmail option GroupReadableDefaultAuthInfoFile
to relax requirement for DefaultAuthInfo file.
Reset timeout after receiving a message to appropriate value if
STARTTLS is in use. Based on patch by Kelsey Cummings
of Sonic.net.
Report correct error messages from the LDAP library for a range of
small negative return values covering those used by OpenLDAP.
Fix compilation with Berkeley DB 5.0 and 6.0. Patch from
Allan E Johannesen of Worcester Polytechnic Institute.
CONFIG: FEATURE(`nopercenthack') takes one parameter: reject or
nospecial which describes whether to disallow "%" in the
local part of an address.
DEVTOOLS: Fix regression in auto-detection of libraries when only
shared libraries are available. Problem reported by
Bryan Costales.
LIBMILTER: Mark communication socket as close-on-exec in case
a user's filter starts other applications.
Based on patch from Paul Howarth.
Portability:
SunOS 5.12 has changed the API for sigwait(2) to conform
with XPG7. Based on patch from Roger Faulkner of Oracle.
Deleted Files:
libsm/path.c
8.14.9/8.14.9 2014/05/21
SECURITY: Properly set the close-on-exec flag for file descriptors
(except stdin, stdout, and stderr) before executing mailers.
Fix a misformed comment in conf.c: "/*" within comment
which may cause a compilation error on some systems.
Problem reported by John Beck of Oracle.
DEVTOOLS: Fix regression in auto-detection of libraries when only
shared libraries are available. Problem reported by
Bryan Costales.
8.14.8/8.14.8 2014/01/26
Properly initialize all OpenSSL algorithms for versions before
OpenSSL 0.9.8o. Without this SHA2 algorithms may not
work properly, causing for example failures for certs
that use sha256WithRSAEncryption as signature algorithm.
When looking up hostnames, ensure only to return those records
for the requested family (AF_INET or AF_INET6).
On system that have NEEDSGETIPNODE and NETINET6
this may have failed and cause delivery problems.
Problem noted by Kees Cook.
A new mailer flag '!' is available to suppress an MH hack
that drops an explicit From: header if it is the
same as what sendmail would generate.
Add an FFR (for future release) to use uncompressed IPv6 addresses,
i.e., they will not contain "::". For example, instead
of ::1 it will be 0:0:0:0:0:0:0:1. This means that
configuration data (including maps, files, classes,
custom ruleset, etc) have to use the same format.
This will be turned on in 8.15. It can be enabled in 8.14

Drop support for IPv4-mapped IPv6 addresses to prevent the MTA
from using a mapped address over a legitimate IPv6 address
and to enforce the proper semantics over the IPv6
connection. Problem noted by Ulrich Sporlein.
Fix a regression introduced in 8.14.6: the wrong list of
macros was sent to a milter in the EHLO stage.
Problem found by Fabrice Bellet, reported via RedHat
(Jaroslav Skarvada).
Fix handling of ORCPT parameter for DSNs: xtext decoding
was not performed and a wrong syntax check was applied
to the "addr-type" field. Problem noted by Dan Lukes
of Obludarium.
Fix handling of NUL characters in the MIME conversion functions
so that message bodies containing them will be sent
on properly. Note: this usually also affects mails
that are not converted as those functions are used
for other purposes too. Problem noted by Elchonon
Edelson of Lockheed Martin.
Do not perform "duplicate" elimination of recipients if they
resolve to the error mailer using a temporary failure
(4xy) via ruleset 0. Problem noted by Akira Takahashi

8.14.6/8.14.6 2012/12/23
Fix a regression introduced in 8.14.5: if a server offers
two AUTH lines, the MTA would not read them after
STARTTLS has been used and hence SMTP AUTH for
the client side would fail. Problem noted by Lena.
Do not cache hostnames internally in a non case sensitive way
as that may cause addresses to change from lower case
to upper case or vice versa. These header modifications
can cause problems with milters that rely on receiving
headers in the same way as they are being sent out such
as a DKIM signing milter.
If MaxQueueChildren is set then it was possible that new queue
runners could not be started anymore because an
internal counter was subject to a race condition.
If a milter decreases the timeout it waits for a communication
with the MTA, the MTA might experience a write() timeout.
In some situations, the resulting error might have been
ignored. Problem noted by Werner Wiethege.
Note: decreasing the communication timeout in a milter
should not be done without considering the potential
problems.
smfi_setsymlist() now properly sets the list of macros for
the milter which invoked it, instead of a global
list for all milters. Problem reported by
David Shrimpton of the University of Queensland.
If Timeout.resolver.retrans is set to a value larger than 20,
then resolver.retry was temporarily set to 0 for
gethostbyaddr() lookups. Now it is set to 1 instead.
Patch from Peter.
If sendmail could not lock the statistics file due to a system
error, and sendmail later sends a DSN for a mail that
triggered such an error, then sendmail tried to access
memory that was freed before (causing a crash on some
systems). Problem reported by Ryan Stone.
Do not log negative values for size= nor pri= to avoid confusing

Do not cache SMTP extensions across connections as the cache
is based on hostname which may not be a unique identifier
for a server, i.e., different machines may have the
same hostname but provide different SMTP extensions.
Problem noted by Jim Hermann.
Avoid an out-of-bounds access in case a resolver reply for a DNS
map lookup returns a size larger than 1K. Based on a
patch from Dr. Werner Fink of SuSE.
If a job is aborted using the interrupt signal (e.g., control-C from
the keyboard), perform minimal cleanup to avoid invoking
functions that are not signal-safe. Note: in previous
versions the mail might have been queued up already
and would be delivered subsequently, now an interrupt
will always remove the queue files and thus prevent
delivery.
Per RFC 6176, when operating as a TLS client, do not offer SSLv2.
Since TLS session resumption is never used as a client, disable
use of RFC 4507-style session tickets.
Work around gcc4 versions which reverse 25 years of history and
no longer align char buffers on the stack, breaking calls
to resolver functions on strict alignment platforms.
Found by Stuart Henderson of OpenBSD.
Read at most two AUTH lines from a server greeting (up to two
lines are read because servers may use "AUTH mechs" and
"AUTH=mechs"). Otherwise a malicious server may exhaust
the memory of the client. Bug report by Nils of MWR
InfoSecurity.
Avoid triggering an assertion in the OpenLDAP code when the
connection to an LDAP server is lost while making a query.
Problem noted and patch provided by Andy Fiddaman.
If ConnectOnlyTo is set and sendmail is compiled with NETINET6
it would try to use an IPv6 address if an IPv4 (or
unparseable) address is specified.
If SASLv2 is used, make sure that the macro {auth_authen} is
stored in xtext format to avoid problems with parsing
it. Problem noted by Christophe Wolfhugel.
CONFIG: FEATURE(`ldap_routing') in 8.14.4 tried to add a missing

in the {cn_subject} or {cn_issuer} macro. Patch inspired
by Matthias Andree's changes for fetchmail.
During the generation of a queue identifier an integer overflow
could occur which might result in bogus characters

Patch from Kazuteru Okahashi of IIJ.
If a Diffie-Hellman cipher is selected for STARTTLS, the
handshake could fail with some TLS implementations
because the prime used by the server is not long enough.
Note: the initialization of the DSA/DH parameters for

If a milter sets the reply code to "421" during the transfer
of the body, the SMTP server will terminate the SMTP session
with that error to match the behavior of the other callbacks.

missing disk space in the mail queue. Based on patch
from Martin Poole of RedHat.
CONFIG: Using FEATURE(`ldap_routing')'s `nodomain' argument would

8.14.3/8.14.3 2008/05/03
During ruleset processing the generation of a key for a map
lookup and the parsing of the default value was broken
for some macros, e.g., $|, which caused the BlankSub
character to be inserted into the workspace and thus
failures, e.g., rules that should have matched did not.
8.14.2 caused a regression: it accessed (macro) storage which was

8.14.2/8.14.2 2007/11/01
If a message was queued and it contained 8 bit characters in
a From: or To: header, then those characters could be
"mistaken" for internal control characters during a queue
run and trigger various consistency checks. Problem
noted by Neil Rickert of Northern Illinois University.
If MaxMimeHeaderLength is set to a value greater than 0 (which
it is by default) then even if the Linelimit parameter
is 0, sendmail corrupted in the non-transfer-encoding
case every MAXLINE-1 characters. Patch from John Gardiner
Myers of Proofpoint.
Setting the suboption DeliveryMode for DaemonPortOptions did not
work in earlier 8.14 versions.
Note: DeliveryMode=interactive is silently converted to
background if a milter can reject or delete a recipient.
Prior to 8.14 this happened only if milter could delete
recipients.
ClientRate should trigger when the limit was exceeded (as
documented), not when it was reached. Patch from
John Beck of Sun Microsystems.
Force a queue run for -qGqueuegroup even if no runners are
specified (R=0) and forking (F=f) is requested.
When multiple results are requested for a DNS map lookup
(-z and -Z), return only those that are relevant for
the query (not also those in the "additional section".)
If the message transfer time to sendmail (when acting as server)
exceeds Timeout.queuewarn or Timeout.queuereturn and
the message is refused (by a milter), sendmail previously
created a delivery status notification (DSN). Patch
from Doug Heath of The Hertz Corporation.
A code change in Cyrus-SASL 2.1.22 for sasl_decode64() requires
the MTA to deal with some input (i.e., "=") itself.
Problem noted by Eliot Lear.
sendmail counted a delivery as successful if PIPELINING is
compiled in but not offered by the server and the
delivery failed temporarily. Patch from Werner Wiethege.
If getting the result of an LDAP query times out then close the
map so it will be reopened on the next lookup. This
should help "failover" configurations that specify more
than one LDAP server.
If check_compat returns $#discard then a "savemail panic" could
be triggered under some circumstances (e.g., requiring
a system which does not have the compile time flag
HASFLOCK set). Based on patch by Motonori Nakamura
of National Institute of Informatics, Japan.
If a milter rejected a recipient, the count for nrcpts= in the
logfile entry might have been wrong. Problem found by
Petra Humann of TU Dresden.
If a milter invoked smfi_chgfrom() where ESMTP arguments are not
NULL, the message body was lost. Patch from Motonori
Nakamura of National Institute of Informatics, Japan.

LIBMILTER: smfi_version() did not properly extract the patchlevel
from the version number, however, the returned value was

8.14.1/8.14.1 2007/04/03
Even though a milter rejects a recipient the MTA will still keep
it in its list of recipients and deliver to it if the
transaction is accepted. This is a regression introduced
in 8.14.0 due to the change for SMFIP_RCPT_REJ. Bug
found by Andy Fiddaman.
The new DaemonPortOptions which begin with a lower case character
could not be set in 8.14.0.
If a server shut down the connection in response to a STARTTLS
command, sendmail would log a misleading error message
due to an internal inconsistency. Problem found by

8.14.0/8.14.0 2007/01/31
Header field values are now 8 bit clean. Notes:
- header field names are still restricted to 7 bit.
- RFC 2822 allows only 7 bit (US-ASCII) characters in
headers.
Preserve spaces after the colon in a header. Previously, any
number of spaces after the colon would be changed to
exactly one space.
In some cases of deeply nested aliases/forwarding, mail can
be silently lost. Moreover, the MaxAliasRecursion
limit may be reached too early, e.g., the counter
may be off by a factor of 4 in case of a sequence of
.forward files that refer to others. Patch from
Motonori Nakamura of Kyoto University.
Fix a regression in 8.13.8: if InputMailFilters is set then
"sendmail -bs" can trigger an assertion because the
hostname of the client is undefined. It is now set
to "localhost" for the xxfi_connect() callback.
Avoid referencing a freed variable during cleanup when terminating.
Problem reported and diagnosed by Joe Maimon.
New option HeloName to set the name for the HELO/EHLO command.
Patch from Nik Clayton.
New option SoftBounce to issue temporary errors (4xy) instead of

DeliveryMode DeliveryMode
refuseLA RefuseLA
delayLA DelayLA
queueLA QueueLA

New option -K for LDAP maps to replace %1 through %9 in the
lookup key with the LDAP escaped contents of the
arguments specified in the map lookup. Loosely based
on patch from Wolfgang Hottgenroth.
Log the time after which a greet_pause delay triggered. Patch
from Nik Clayton.
If a client is rejected via TCP wrapper or some other check
performed by validate_connection() (in conf.c) then do
not also invoke greet_pause. Problem noted by Jim Pirzyk
of the University of Illinois at Urbana-Champaign.
If a client terminates the SMTP connection during a pause
introduced by greet_pause, then a misleading message
was logged previously. Problem noted by Vernon Schryver
et.al., patch from Matej Vela.
New command "mstat" for control socket to provide "machine
readable" status.
New named config file rule check_eom which is called at the end
of a message, its parameter is the size of the message.
If the macro {addr_type} indicates that the current address
is a header address it also distinguishes between
recipient and sender addresses (as it is done for
envelope addresses).
When a macro is set in check_relay, then its value is accessible
by all transactions in the same SMTP session.
Increase size of key for ldap lookups to 1024 (MAXKEY).
New option MaxNOOPCommands to override default of 20 for the
number of "useless" commands before the SMTP server will
slow down responding.
New option SharedMemoryKeyFile: if shared memory support is
enabled, the MTA can be asked to select a shared memory
key itself by setting SharedMemoryKey to -1 and specifying
a file where to store the selected key.
Try to deal with open HTTP proxies that are used to send spam
by recognizing some commands from them. If the first command
from the client is GET, POST, CONNECT, or USER, then the
connection is terminated immediately.
New PrivacyOptions noactualrecipient to avoid putting
X-Actual-Recipient lines in DSNs revealing the actual
account that addresses map to. Patch from Dan Harkless.
New options B, z, and Z for DNS maps:
-B: specify a domain that is always appended to queries.
-z: specify the delimiter at which to cut off the result of
a query if it is too long.
-Z: specify the maximum number of entries to be concatenated
to form the result of a lookup.
New target "check" in the Makefile of libsm: instead of running tests
implicitly while building libsm, they must be explicitly
started by using "make check".
Fixed some inconsistent checks for NULL pointers that have been
reported by the SATURN tool which has been developed by
Isil Dillig and Thomas Dillig of Stanford University.
Fix a potential race condition caused by a signal handler for
terminated child processes. Problem noted by David F. Skoll.
When a milter deleted a recipient, that recipient could cause a
queue group selection. This has been disabled as it was not
intended.
New operator 'r' for the arith map to return a random number.
Patch from Motonori Nakamura of Kyoto University.
New compile time option MILTER_NO_NAGLE to turn off the Nagle
algorithm for communication with libmilter ("cork" on Linux),
which may improve the communication performance on some
operating systems. Patch from John Gardiner Myers of
Proofpoint.
If sendmail received input that contained a CR without subsequent LF
(thus violating RFC 2821 (2.3.7)), it could previously
generate an additional blank line in the output as the last
line.
Restarting persistent queue runners by sending a HUP signal to
the "queue control process" (QCP) works now.
Increase the length of an input line to 12288 to deal with
really long lines during SMTP AUTH negotiations.
Problem noted by Werner Wiethege.
If ARPANET mode (-ba) was selected STARTTLS would fail (due to
a missing initialization call for that case). Problem
noted by Neil Rickert of Northern Illinois University.
If sendmail is linked against a library that initializes Cyrus-SASL
before sendmail did it (such as libnss-ldap), then SMTP AUTH
could fail for the sendmail client. A patch by Moritz Both
works around the API design flaw of Cyrus-SASLv2.
CONFIG: Make it possible to unset the StatusFile option by
undefining STATUS_FILE. By not setting StatusFile,
the MTA will not attempt to open a statistics file on
each delivery.
CONFIG: New FEATURE(`require_rdns') to reject messages from SMTP
clients whose IP address does not have proper reverse DNS.
Contributed by Neil Rickert of Northern Illinois University
and John Beck of Sun Microsystems.
CONFIG: New FEATURE(`block_bad_helo') to reject messages from SMTP
clients which provide a HELO/EHLO argument which is either
unqualified, or is one of our own names (i.e., the server
name instead of the client name). Contributed by Neil
Rickert of Northern Illinois University and John Beck of
Sun Microsystems.
CONFIG: New FEATURE(`badmx') to reject envelope sender addresses
(MAIL) whose domain part resolves to a "bad" MX record.
Based on contribution from William Dell Wisner.
CONFIG: New macros SMTP_MAILER_LL and RELAY_MAILER_LL to override
the maximum line length of the smtp mailers.
CONFIG: New option `relaytofulladdress' for FEATURE(`access_db')

To:user@example.com RELAY
CONFIG: New subsuboptions eoh and data to specify the list of
macros a milter should receive at those stages in the
SMTP dialogue.
CONFIG: New option confHELO_NAME for HeloName to set the name
for the HELO/EHLO command.
CONFIG: dnsbl and enhdnsbl can now also discard or quarantine
messages by using those values as second argument.
Patches from Nelson Fung.
CONTRIB: cidrexpand uses a hash symbol as comment character and
ignores everything after it unless it is in quotes or
preceded by a backslash.
DEVTOOLS: New macro confMKDIR: if set to a program that creates
directories, then it used for "make install" to create
the required installation directories.
DEVTOOLS: New macro confCCLINK to specify the linker to use for
executables (defaults to confCC).
LIBMILTER: A new version of the milter API has been created that
has several changes which are listed below and documented
in the webpages reachable via libmilter/docs/index.html.
LIBMILTER: The meaning of the version macro SMFI_VERSION has been
changed. It now refers only to the version of libmilter,
not to the protocol version (which is used only internally,
it is not user/milter-programmer visible). Additionally,
a version function smfi_version() has been introduced such
that a milter program can check the libmilter version also
at runtime which is useful if a shared library is used.
LIBMILTER: A new callback xxfi_negotiate() can be used to
dynamically (i.e., at runtime) determine the available
protocol actions and features of the MTA and also to
specify which of these a milter wants to use. This allows
for more flexibility than hardcoding these flags in the
xxfi_flags field of the smfiDesc structure.
LIBMILTER: A new callback xxfi_data() is available so milters
can act on the DATA command.
LIBMILTER: A new callback xxfi_unknown() is available so milters
can receive also unknown SMTP commands.
LIBMILTER: A new return code SMFIS_NOREPLY has been added which
can be used by the xxfi_header() callback provided the
milter requested the SMFIP_NOHREPL protocol action.
LIBMILTER: The new return code SMFIS_SKIP can be used in the
xxfi_body() callback to skip over further body chunks
and directly advance to the xxfi_eom() callback. This
is useful if a milter can make a decision based on the
body chunks it already received without reading the entire
rest of the body and the milter wants to invoke functions
that are only available from the xxfi_eom() callback.
LIBMILTER: A new function smfi_addrcpt_par() can be used to add
new recipients including ESMTP parameters.
LIBMILTER: A new function smfi_chgfrom() can be used to change the
envelope sender including ESMTP parameters.
LIBMILTER: A milter can now request to be informed about rejected
recipients (RCPT) too. This requires to set the protocol
flag SMFIP_RCPT_REJ during option negotiation. Whether
a RCPT has been rejected can be checked by comparing the
value of the macro {rcpt_mailer} with "error".
LIBMILTER: A milter can now override the list of macros that it
wants to receive from the MTA for each protocol step
by invoking the function smfi_setsymlist() during option
negotiation.
LIBMILTER: A milter can receive header field values with all
leading spaces by requesting the SMFIP_HDR_LEADSPC
protocol action. Also, if the flag is set then the MTA
does not add a leading space to headers that are added,
inserted, or replaced.
LIBMILTER: If a milter sets the reply code to "421" for the HELO
callback, the SMTP server will terminate the SMTP session
with that error to match the behavior of all other callbacks.

8.13.8/8.13.8 2006/08/09
Fix a regression in 8.13.7: if shared memory is activated, then
the server can erroneously report that there is
insufficient disk space. Additionally make sure that
an internal variable is set properly to avoid those
misleading errors. Based on patch from Steve Hubert
of University of Washington.
Fix a regression in 8.13.7: the PidFile could be removed after
the process that forks the daemon exited, i.e., if
sendmail -bd is invoked. Problem reported by Kan Sasaki
of Fusion Communications Corp. and Werner Wiethege.
Avoid opening qf files if QueueSortOrder is "none". Patch from
David F. Skoll.
Avoid a crash when finishing due to referencing a freed variable.
Problem reported and diagnosed by Moritz Jodeit.
CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4
range (0..255).
LIBMILTER: The "hostname" argument of the xxfi_connect() callback
previously was the equivalent of {client_ptr}. However,
this did not match the documentation of the function, hence
it has been changed to {client_name}. See doc/op/op.me
about these macros.
8.13.7/8.13.7 2006/06/14
A malformed MIME structure with many parts can cause sendmail to
crash while trying to send a mail due to a stack overflow,
e.g., if the stack size is limited (ulimit -s). This
happens because the recursion of the function mime8to7()
was not restricted. The function is called for MIME 8 to
7 bit conversion and also to enforce MaxMimeHeaderLength.
To work around this problem, recursive calls are limited to
a depth of MAXMIMENESTING (20); message content after this
limit is treated as opaque and is not checked further.
Problem noted by Frank Sheiness.
The changes to the I/O layer in 8.13.6 caused a regression for
SASL mechanisms that use the security layer, e.g.,
DIGEST-MD5. Problem noted by Robert Stampfli.
If a timeout occurs while reading a message (during the DATA phase)
a df file might have been left behind in the queue.
This was another side effect of the changes to the I/O
layer made in 8.13.6.
Several minor problems have been fixed that were found by a
Coverity scan of sendmail 8 as part of the NetBSD
distribution. See http://scan.coverity.com/
Note: the scan generated also a lot of "false positives",
e.g., "error" reports about situations that cannot happen.
Most of those code places are marked with lint(1) comments
like NOTREACHED, but Coverity does not understand those.
Hence an explicit assertion has been added in some cases
to avoid those false positives.
If the start of the sendmail daemon fails due to a configuration
error then in some cases shared memory segments or pid
files were not removed.
If DSN support is disabled via access_db, then related ESMTP
parameters for MAIL and RCPT should be rejected. Problem
reported by Akihiro Sagawa.
Enabling zlib compression in OpenSSL 0.9.8[ab] breaks the padding
bug work-around. Hence if sendmail is linked against
either of these versions and compression is available,
the padding bug work-around is turned off. Based on
patch from Victor Duchovni of Morgan Stanley.
CONFIG: FEATURE(`dnsbl') and FEATURE(`enhdnsbl') used
blackholes.mail-abuse.org as default domain for lookups,
however, that list is no longer available. To avoid
further problems, no default value is available anymore,
but an argument must be specified.
Portability:
Fix compilation on OSF/1 for sfsasl.c. Patch from
Pieter Bowman of the University of Utah.
8.13.6/8.13.6 2006/03/22
SECURITY: Replace unsafe use of setjmp(3)/longjmp(3) in the server
and client side of sendmail with timeouts in the libsm I/O
layer and fix problems in that code. Also fix handling of
a buffer in sm_syslog() which could have been used as an
attack vector to exploit the unsafe handling of
setjmp(3)/longjmp(3) in combination with signals.
Problem detected by Mark Dowd of ISS X-Force.
Handle theoretical integer overflows that could triggered if
the server accepted headers larger than the maximum
(signed) integer value. This is prevented in the default
configuration by restricting the size of a header, and on
most machines memory allocations would fail before reaching
those values. Problems found by Phil Brass of ISS.
If a server returns 421 for an RSET command when trying to start
another transaction in a session while sending mail, do
not trigger an internal consistency check. Problem found
by Allan E Johannesen of Worcester Polytechnic Institute.
If a server returns a 5xy error code (other than 501) in response
to a STARTTLS command despite the fact that it advertised
STARTTLS and that the code is not valid according to RFC
2487 treat it nevertheless as a permanent failure instead
of a protocol error (which has been changed to a
temporary error in 8.13.5). Problem reported by Jeff
A. Earickson of Colby College.
Clear SMTP state after a HELO/EHLO command. Patch from John
Myers of Proofpoint.
Observe MinQueueAge option when gathering entries from the queue
for sorting etc instead of waiting until the entries are
processed. Patch from Brian Fundakowski Feldman.
Set up TLS session cache to properly handle clients that try to
resume a stored TLS session.
Properly count the number of (direct) child processes such that
a configured value (MaxDaemonChildren) is not exceeded.
Based on patch from Attila Bruncsak.
LIBMILTER: Remove superfluous backslash in macro definition
(libmilter.h). Based on patch from Mike Kupfer of
Sun Microsystems.
LIBMILTER: Don't try to set SO_REUSEADDR on UNIX domain sockets.
This generates an error message from libmilter on
Solaris, though other systems appear to just discard the
request silently.
LIBMILTER: Deal with sigwait(2) implementations that return
-1 and set errno instead of returning an error code
directly. Patch from Chris Adams of HiWAAY Informations
Services.
Portability:
Fix compilation checks for closefrom(3) and statvfs(2)
in NetBSD. Problem noted by S. Moonesamy, patch from
Andrew Brown.
8.13.5/8.13.5 2005/09/16
Store the filesystem identifier of the df/ subdirectory (if it
exists) in an internal structure instead of the base
directory. This structure is used decide whether there
is enough free disk space when selecting a queue, hence
without this change queue selection could fail if a df/
subdirectory exists and is on a different filesystem
than the base directory.
Use the queue index of the df file (instead of the qf file) for
checking whether a link(2) operation can be used to split
an envelope across queue groups. Problem found by
Werner Wiethege.
If the list of items in the queue is larger than the maximum
number of items to process, sort the queue first and
then cut the list off instead of the other way around.
Patch from Matej Vela of Rudjer Boskovic Institute.
Fix helpfile to show full entry for ETRN. Problem noted by
Penelope Fudd, patch from Neil Rickert of Northern Illinois
University.
FallbackSmartHost should also be tried on temporary errors.
From John Beck of Sun Microsystems.
When a server responds with 421 to the STARTTLS command then treat
it as a temporary error, not as protocol error. Problem
noted by Andrey J. Melnikoff.
Properly define two functions in libsm as static because their
prototype used static too. Patch from Peter Klein.
Fix syntax errors in helpfile for MAIL and RCPT commands.
LIBMILTER: When smfi_replacebody() is called with bodylen equals
zero then do not silently ignore that call. Patch from
Gurusamy Sarathy of Active State.
LIBMILTER: Recognize "421" also in a multi-line reply to terminate
the SMTP session with that error. Fix from Brian Kantor.
Portability: New option HASSNPRINTF which can be set if the OS
has a properly working snprintf(3) to get rid
of the last two (safe) sprintf(3) calls in the
source code.
Add support for AIX 5.3.
Add support for SunOS 5.11 (aka Solaris 11).
Add support for Darwin 8.x. Patch from Lyndon Nerenberg.
OpenBSD 3.7 has removed support for NETISO.
CONFIG: Add OSTYPE(freebsd6) for FreeBSD 6.X.
Set DontBlameSendmail to AssumeSafeChown and
GroupWritableDirPathSafe for OSTYPE(darwin).
Patch from Lyndon Nerenberg.
Some features still used 4.7.1 as enhanced status code which
was supposed to be eliminated in 8.13.0 because some
broken systems misinterpret it as a permanent error.
Patch from Matej Vela of Rudjer Boskovic Institute.

The bug fixes in 8.13.3 for connection handling uncovered a
different error which could result in connections that
stay in CLOSE_WAIT state due to a variable that was not
properly initialized. Problem noted by Michael Sims.
Deal with empty hostnames in hostsignature(). This bug could lead
to an endless loop when doing LMTP deliveries to another
host. Problem first reported by Martin Lathoud and
tracked down by Gael Roualland.
Make sure return parameters are initialized in getmxrr(). Problem
found by Gael Roualland using valgrind.
If shared memory is used and the RunAsUser option is set, then the
owner and group of the shared memory segment is set to
the ids specified RunAsUser and the access mode is set
to 0660 to allow for updates by sendmail processes.
The number of queue entries that is (optionally) kept in shared
memory was wrong in some cases, e.g., envelope splitting
and bounce generation.
Undo a change made in 8.13.0 to silently truncate long strings
in address rewriting because the message can be triggered
for header checks where long strings are legitimate.
Problem reported by Mary Verge DeSisto, and tracked
down with the help of John Beck of Sun Microsystems.
The internal stab map did not obey the -m flag. Patch from
Rob McMahon of Warwick University, England.
The socket map did not obey the -f flag. Problem noted by
Dan Ringdahl, forwarded by Andrzej Filip.
The addition of LDAP recursion in 8.13.0 broke enforcement of
the LDAP map -1 argument which tells the MTA to only
return success if and only if a single LDAP match is found.
Add additional error checks in the MTA for milter communication
to avoid a possible segmentation fault. Based on patch
by Joe Maimon.
Do not trigger an assertion if X509_digest() returns success but
does not assign a value to its output parameter. Based
on patch by Brian Kantor.
Add more checks when resetting internal AUTH data (applies only
to Cyrus SASL version 2). Otherwise an SMTP session might
be dropped after an AUTH failure.
Portability:
Add LA_LONGLONG as valid LA_TYPE type for systems that use
"long long" to read load average data, e.g.,
AIX 5.1 in 32 bit mode. Note: this has to be set
"by hand", it is not (yet) automatically detected.
Problem noted by Burak Bilen.
Use socklen_t for accept(), etc. on AIX 5.x. This should
fix problems when compiling in 64 bit mode.

Make sure a connection is not reused after it has been closed
due to a 421 error. Problem found by Allan E Johannesen
of Worcester Polytechnic Institute.
Avoid triggering an assertion when sendmail is interrupted while
closing a connection. Problem found by Allan E Johannesen
of Worcester Polytechnic Institute.
Regression: a change in 8.13.2 caused sendmail not to try the
next MX host (or FallbackMXhost if configured) when, at
connection open, the current server returns a 4xy or 5xy
SMTP reply code. Problem noted by Mark Tranchant.
8.13.2/8.13.2 2004/12/15
Do not split the first header even if it exceeds the internal
buffer size. Previously a part of such a header would
end up in the body of the message. Problem noted by
Simple Nomad of BindView.
Do not complain about "cataddr: string too long" when checking
headers that do not contain RFC 2822 addresses.
Problem noted by Rich Graves of Brandeis University.
If a server returns a 421 reply to the RSET command between
message deliveries, do not attempt to deliver any more
messages on that connection. This prevents bogus "Bad
file number" recipient status. Problem noted by
Allan E Johannesen of Worcester Polytechnic Institute.
Allow trailing white space in EHLO command as recommended by RFC
2821. Problem noted by Ralph Santagato of SBC Services.
Deal with clients which use AUTH but negotiate a smaller buffer size
for data exchanges than the value used by sendmail, e.g.,
Cyrus IMAP lmtp server. Based on patch by Jamie Clark.
When passing ESMTP arguments for RCPT to a milter, do not cut
them off at a comma. Problem noted by Krzysztof Oledzki.

Fix SuperSafe=PostMilter behavior when a milter replaces a body
but the data file is not yet stored on disk because it is
smaller than the size of the memory buffer. Problem noted

Fix certificate revocation list support; if a CRL was specified
but the other side presented a cert that was signed by
a different (trusted) CA than the one which issued the CRL,

Fix bug in conversion from 8bit to quoted-printable. Problem found
by Christof Haerens, patch from Per Hedeland.
Add support for LDAP recursion based on types given to attribute
specifications in an LDAP map definition. This allows
LDAP queries to return a new query, a DN, or an LDAP
URL which will in turn be queried. See the ``LDAP
Recursion'' section of doc/op/op.me for more information.
Based on patch from Andrew Baucom.
Extend the default LDAP specifications for AliasFile
(O AliasFile=ldap:) and file classes (F{X}@LDAP) to
include support for LDAP recursion via new attributes.
See ``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section
of cf/README for more information.
New option for LDAP maps: the -w option allows you to specify the
LDAP API/protocol version to use. The default depends on
the LDAP library.
New option for LDAP maps: the -H option allows you to specify an
LDAP URI instead of specifying the LDAP server via -h host
and -p port. This also allows for the use of LDAP over
SSL and connections via named sockets if your LDAP
library supports it.
New compile time flag SM_CONF_LDAP_INITIALIZE: set this if
ldap_initialize(3) is available (and LDAPMAP is set).
If MaxDaemonChildren is set and a command is repeated too often
during a SMTP session then terminate it just like it is
done for too many bad SMTP commands.
Basic connection rate control support has been added: the daemon
maintains the number of incoming connections per client
IP address and total in the macros {client_rate} and
{total_rate}, respectively. These macros can be used
in the cf file to impose connection rate limits.
A new option ConnectionRateWindowSize (default: 60s)
determines the length of the interval for which the
number of connections is stored. Based on patch from
Jose Marcio Martins da Cruz, Ecole des Mines de Paris.
Add optional protection from open proxies and SMTP slammers which
send SMTP traffic without waiting for the SMTP greeting.
If enabled by the new ruleset greet_pause (see
FEATURE(`greet_pause')), sendmail will wait the specified
amount of time before sending the initial 220 SMTP
greeting. If any traffic is received before then, a 554
SMTP response is sent and all SMTP commands are rejected
during that connection.
If 32 NOOP (or unknown/bad) commands are issued by a client the SMTP
server could sleep for a very long time. Fix based on
patch from Tadashi Kobayashi of IIJ.
Fix a potential memory leak in persistent queue runners if the
number of entries in the queue exceeds the limit of jobs.
Problem noted by Steve Hubert of University of Washington.
Do not use 4.7.1 as enhanced status code because some broken systems
misinterpret it as a permanent error.
New value for SuperSafe: PostMilter which will delay fsync() until
all milters accepted the mail. This can increase
performance if many mails are rejected by milters due to
body scans. Based on patch from David F. Skoll.
New macro {msg_id} which contains the value of the Message-Id:
header, whether provided by the client or generated by
sendmail.
New macro {client_connections} which contains the number of open
connections in the SMTP server for the client IP address.
Based on patch from Jose Marcio Martins da Cruz, Ecole des
Mines de Paris.
sendmail will now remove its pidfile when it exits. This was done
to prevent confusion caused by running sendmail stop
scripts two or more times, where the second and subsequent
runs would report misleading error messages about sendmail's
pid no longer existing. See section 1.3.15 of doc/op/op.me
for a discussion of the implications of this, including
how to correct broken scripts which may have depended on
the old behavior. From John Beck of Sun Microsystems.
Support per-daemon input filter lists which override the default
filter list specified in InputMailFilters. The filters
can be listed in the I= equate of DaemonPortOptions.
Do not add all domain prefixes of the hostname to class 'w'. If
your configuration relies on this behavior, you have to
add those names to class 'w' yourself. Problem noted
by Sander Eerkes.
Support message quarantining in the mail queue. Quarantined
messages are not run on normal queue displays or runs
unless specifically requested with -qQ. Quarantined queue
files are named with an hf prefix instead of a qf prefix.
The -q command line option now can specify which queue to display
or run. -qQ operates on quarantined queue items. -qL
operates on lost queue items.
Restricted mail queue runs and displays can be done based on the
quarantined reason using -qQtext to run or display
quarantined items if the quarantine reason contains the
given text. Similarly, -q!Qtext will run or display
quarantined items which do not have the given text in the
quarantine reason.
Items in the queue can be quarantined or unquarantined using the
new -Q option. See doc/op/op.me for more information.
When displaying the quarantine mailq with 'mailq -qQ', the
quarantine reason is shown in a new line prefixed by
"QUARANTINE:".
A new error code for the $#error mailer, $@ quarantine, can be used
to quarantine messages in check_* (except check_compat) and
header check rulesets. The $: of the mailer triplet will
be used for the quarantine reason.
Add a new quarantine count to the mailstats collected.
Add a new macro ${quarantine} which is the quarantine reason for a
message if it is quarantined.
New map type "socket" for a trivial query protocol over UNIX domain
or TCP sockets (requires compile time option SOCKETMAP).
See sendmail/README and doc/op/op.me for details as well as
socketmapServer.pl and socketmapClient.pl in contrib.
Code donated by Bastiaan Bakker of LifeLine Networks.
Define new macro ${client_ptr} which holds the result of the PTR
lookup for the client IP address. Note: this is the same
as ${client_name} if and only if ${client_resolve} is OK.
Add a new macro ${nbadrcpts} which contains the number of bad
recipients received so far in a transaction.
Call check_relay with the value of ${client_name} to deal with bogus
DNS entries. See also FEATURE(`use_client_ptr'). Problem
noted by Kai Schlichting.

Add a new AuthOption=m flag to require the use of mechanisms which
support mutual authentication. From Kenneth Murchison of
Oceana Matrix Ltd.
Fix logging of TLS related problems (introduced in 8.12.11).
The macros {auth_author} and {auth_authen} are stored in xtext

problems with parsing them. Problem noted by Pierangelo
Masarati of SysNet s.n.c.
New option AuthRealm to set the authentication realm that is
passed to the Cyrus SASL library. Patch from Gary Mills
of the University of Manitoba.
Enable AUTH mechanism EXTERNAL if STARTTLS verification was
successful, otherwise relaying would be allowed if
EXTERNAL is listed in TRUST_AUTH_MECH() and STARTTLS
is active.
Add basic support for certificate revocation lists. Note: if a
CRLFile is specified but the file is unusable, STARTTLS
is disabled. Based on patch by Ralf Hornik.
Enable workaround for inconsistent Cyrus SASLv1 API for mechanisms
DIGEST-MD5 and LOGIN.
Write pid to file also if sendmail only acts as persistent queue
runner. Proposed by Gary Mills of the University of Manitoba.
Keep daemon pid file(s) locked so other daemons don't try to
overwrite each other's pid files.
Increase maximum length of logfile fields for {cert_subject} and
{cert_issuer} from 128 to 256. Requested by Christophe
Wolfhugel of France Telecom.
Log the TLS verification message on the STARTTLS= log line at
LogLevel 12 or higher.
If the MSP is invoked with the verbose option (-v) then it will
try to use the SMTP command VERB to propagate this option
to the MTA which in turn will show the delivery just like
it was done before the default 8.12 separation of MSP and
MTA. Based on patch by Per Hedeland.
If a daemon is refusing connections for longer than the time specified
by the new option RejectLogInterval (default: 3 hours) due
to high load, log this information. Patch from John Beck
of Sun Microsystems.
Remove the ability for non-trusted users to raise the value of
CheckpointInterval on the command line.
New mailer flag 'B' to strip leading backslashes, which is a
subset of the functionality of the 's' flag.
New mailer flag 'W' to ignore long term host status information.
Patch from Juergen Georgi of RUS University of Stuttgart.
Enable generic mail filter API (milter) by default. To turn
it off, add -DMILTER=0 to the compile time options.
An internal SMTP session discard flag was lost after an RSET/HELO/EHLO
causing subsequent messages to be sent instead of being
discarded. This also caused milter callbacks to be called
out of order after the SMTP session was reset.
New option RequiresDirfsync to turn off the compile time flag
REQUIRES_DIR_FSYNC at runtime. See sendmail/README for
further information.
New command line option -D logfile to send debug output to
the indicated log file instead of stdout.
Add Timeout.queuereturn.dsn and Timeout.queuewarn.dsn to control
queue return and warning times for delivery status
notifications.
New queue sort order option: 'n'one for not sorting the queue entries
at all.
Several more return values for ruleset srv_features have been added
to enable/disable certain features in the server per
connection. See doc/op/op.me for details.
Support for SMTP over SSL (smtps), activated by Modifier=s
for DaemonPortOptions.
Continue with DNS lookups on ECONNREFUSED and TRY_AGAIN when
trying to canonify hostnames. Suggested by Neil Rickert
of Northern Illinois University.
Add support for a fallback smart host (option FallbackSmartHost) to
be tried as a last resort after all other fallbacks. This
is designed for sites with partial DNS (e.g., an accurate
view of inside the company, but an incomplete view of
outside). From John Beck of Sun Microsystems.
Enable timeout for STARTTLS even if client does not start the TLS
handshake. Based on patch by Andrey J. Melnikoff.
Remove deprecated -v option for PH map, use -k instead. Patch from
Mark Roth of the University of Illinois at Urbana-Champaign.
libphclient is version 1.2.x by default, if version 1.1.x is required
then compile with -DNPH_VERSION=10100. Patch from Mark Roth
of the University of Illinois at Urbana-Champaign.
Add Milter.macros.eom, allowing macros to be sent to milter
applications for use in the xxfi_eom() callback.
New macro {time} which contains the output of the time(3) function,
i.e., the number of seconds since 0 hours, 0 minutes,
0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
If check_relay sets the reply code to "421" the SMTP server will
terminate the SMTP session with a 421 error message.
Get rid of dead code that tried to access the environment variable
HOSTALIASES.
Deprecate the use of ErrorMode=write. To enable this in 8.13
compile with -DUSE_TTYPATH=1.
Header check rulesets using $>+ (do not strip comments) will get
the header value passed in without balancing quotes,
parentheses, and angle brackets. Based on patch from
Oleg Bulyzhin.
Do not complain and fix up unbalanced quotes, parentheses, and
angle brackets when reading in rulesets. This allows
rules to be written for header checks to catch strings
that contain quotes, parentheses, and/or angle brackets.
Based on patch from Oleg Bulyzhin.
Do not close socket when accept(2) in the daemon encounters
some temporary errors like ECONNABORTED.
Added list of CA certificates that are used by members of the
sendmail consortium, see CACerts.
Portability:
Two new compile options have been added:
HASCLOSEFROM System has closefrom(3).
HASFDWALK System has fdwalk(3).
Based on patch from John Beck of Sun Microsystems.
The Linux kernel version 2.4 series has a broken flock() so
change to using fcntl() locking until they can fix
it. Be sure to update other sendmail related
programs to match locking techniques.
New compile time option NEEDINTERRNO which should be set
if <errno.h> does not declare errno itself.
Support for UNICOS/mk and UNICOS/mp added, some changes for
UNICOS. Patches contributed by Aaron Davis and
Brian Ginsbach, Cray Inc., and Manu Mahonen of
Center for Scientific Computing.
Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
Extend support to Darwin 7.x/Mac OS X 10.3 (a.k.a. Panther).
Remove path from compiler definition for Interix because
Interix 3.0 and 3.5 put gcc in different locations.
Also use <sys/mkdev.h> to get the correct
major()/minor() definitions. Based on feedback
from Mark Funkenhauser.
CONFIG: Add support for LDAP recursion to the default LDAP searches
for maps via new attributes. See the ``USING LDAP FOR
ALIASES, MAPS, and CLASSES'' section of cf/README and
cf/sendmail.schema for more information.
CONFIG: Make sure confTRUSTED_USER is valid even if confRUN_AS_USER
is of the form "user:group" when used for submit.mc.
Problem noted by Carsten P. Gehrke, patch from Neil Rickert
of Northern Illinois University.
CONFIG: Add a new access DB value of QUARANTINE:reason which
instructs the check_* (except check_compat) to quarantine
the message using the given reason.
CONFIG: Use "dns -R A" as map type for dnsbl (just as for enhdnsbl)
instead of "host" to avoid problem with looking up other
DNS records than just A.
CONFIG: New option confCONNECTION_RATE_WINDOW_SIZE to define the
length of the interval for which the number of incoming
connections is maintained.
CONFIG: New FEATURE(`ratecontrol') to set the limits for connection
rate control for individual hosts or nets.
CONFIG: New FEATURE(`conncontrol') to set the limits for the
number of open SMTP connections for individual hosts or nets.
CONFIG: New FEATURE(`greet_pause') enables open proxy and SMTP
slamming protection described above. The feature can
take an argument specifying the milliseconds to wait and/or
use the access database to look the pause time based on
client hostname, domain, IP address, or subnet.
CONFIG: New FEATURE(`use_client_ptr') to have check_relay use
$&{client_ptr} as its first argument. This is useful for
rejections based on the unverified hostname of client,
which turns on the same behavior as in earlier sendmail
versions when delay_checks was not in use. See also entry
above about check_relay being invoked with ${client_name}.
CONFIG: New option confREJECT_LOG_INTERVAL to specify the log
interval when refusing connections for this long.
CONFIG: Remove quotes around usage of confREJECT_MSG; in some cases
this requires a change in a mc file. Requested by
Ted Roberts of Electronic Data Systems.
CONFIG: New option confAUTH_REALM to set the authentication realm
that is passed to the Cyrus SASL library. Patch from
Gary Mills of the University of Manitoba.
CONFIG: Rename the (internal) classes {tls}/{src} to {Tls}/{Src}
to follow the naming conventions.
CONFIG: Add a third optional argument to local_lmtp to specify
the A= argument.
CONFIG: Remove the f flag from the default mailer flags of
local_lmtp.
CONFIG: New option confREQUIRES_DIR_FSYNC to turn off the compile
time flag REQUIRES_DIR_FSYNC at runtime.
CONFIG: New LOCAL_UUCP macro to insert rules into the generated
cf file at the same place where MAILER(`uucp') inserts
its rules.
CONFIG: New options confTO_QUEUERETURN_DSN and confTO_QUEUEWARN_DSN
to control queue return and warning times for delivery
status notifications.
CONFIG: New option confFALLBACK_SMARTHOST to define FallbackSmartHost.
CONFIG: Add the mc file which has been used to create the cf
file to the end of the cf file when using make in cf/cf/.
Patch from Richard Rognlie.
CONFIG: FEATURE(nodns) has been removed, it was a no-op since 8.9.
Use ServiceSwitchFile to turn off DNS lookups, see
doc/op/op.me.
CONFIG: New option confMILTER_MACROS_EOM (sendmail Milter.macros.eom
option) defines macros to be sent to milter applications for
use in the xxfi_eom() callback.
CONFIG: New option confCRL to specify file which contains
certificate revocations lists.
CONFIG: Add a new value (sendertoo) for the third argument to
FEATURE(`ldap_routing') which will reject the SMTP
MAIL From: command if the sender address doesn't exist
in LDAP. See cf/README for more information.
CONFIG: Add a fifth argument to FEATURE(`ldap_routing') which
instructs the rulesets on whether or not to do a domain
lookup if a full address lookup doesn't match. See cf/README
for more information.
CONFIG: Add a sixth argument to FEATURE(`ldap_routing') which
instructs the rulesets on whether or not to queue the mail
or give an SMTP temporary error if the LDAP server can't be
reached. See cf/README for more information. Based on
patch from Billy Ray Miller of Caterpillar.
CONFIG: Experimental support for MTAMark, see cf/README for details.
CONFIG: New option confMESSAGEID_HEADER to define a different
Message-Id: header format. Patch from Bastiaan Bakker
of LifeLine Networks.
CONTRIB: New version of cidrexpand which uses Net::CIDR. From
Derek J. Balling.
CONTRIB: oldbind.compat.c has been removed due to security problems.
Found by code inspection done by Reasoning, Inc.
DEVTOOLS: Add an example file for devtools/Site/, contributed
by Neil Rickert of Northern Illinois University.
LIBMILTER: Add new function smfi_quarantine() which allows the
filter's EOM routine to quarantine the current message.
Filters which use this function must include the
SMFIF_QUARANTINE flag in the registered smfiDesc structure.
LIBMILTER: If a milter sets the reply code to "421", the SMTP server
will terminate the SMTP session with that error.
LIBMILTER: Upon filter shutdown, libmilter will not remove a
named socket in the file system if it is running as root.
LIBMILTER: Add new function smfi_progress() which allows the filter
to notify the MTA that an EOM operation is still in progress,
resetting the timeout.
LIBMILTER: Add new function smfi_opensocket() which allows the filter
to attempt to establish the interface socket, and detect
failure to do so before calling smfi_main().
LIBMILTER: Add new function smfi_setmlreply() which allows the
filter to return a multi-line SMTP reply.
LIBMILTER: Deal with more temporary errors in accept() by ignoring
them instead of stopping after too many occurred.
Suggested by James Carlson of Sun Microsystems.
LIBMILTER: Fix a descriptor leak in the sample program found in
docs/sample.html. Reported by Dmitry Adamushko.
LIBMILTER: The sample program also needs to use SMFIF_ADDRCPT.
Reported by Carl Byington of 510 Software Group.
LIBMILTER: Document smfi_stop() and smfi_setdbg(). Patches
from Bryan Costales.
LIBMILTER: New compile time option SM_CONF_POLL; define this if
poll(2) should be used instead of select(2).
LIBMILTER: New function smfi_insheader() and related protocol
amendments to support header insertion operations.
MAIL.LOCAL: Add support for hashed mail directories, see
mail.local/README. Contributed by Chris Adams of HiWAAY
Informations Services.
MAILSTATS: Display quarantine message counts.
MAKEMAP: Add new flag -D to specify the comment character to use
instead of '#'.
VACATION: Add new flag -j to auto-respond to messages regardless of
whether or not the recipient is listed in the To: or Cc:
headers.
VACATION: Add new flag -R to specify the envelope sender address
for the auto-response message.

Use QueueFileMode when opening qf files. This error was a
regression in 8.12.10. Problem detected and diagnosed
Lech Szychowski of the Polish Power Grid Company.
Properly count the number of queue runners in a work group and
make sure the total limit of MaxQueueChildren is not
exceeded. Based on patch from Takayuki Yoshizawa of
Techfirm, Inc.
Take care of systems that can generate time values where the
seconds can exceed the usual range of 0 to 59.
Problem noted by Randy Diffenderfer of EDS.
Avoid regeneration of identical queue identifiers by processes
whose process id is the same as that of the initial
sendmail process that was used to start the daemon.
Problem noted by Randy Diffenderfer of EDS.
When a milter invokes smfi_delrcpt() compare the supplied
recipient address also against the printable addresses
of the current list to deal with rewritten addresses.
Based on patch from Sean Hanson of The Asylum.
BadRcptThrottle now also works for addresses which return the
error mailer, e.g., virtusertable entries with the
right hand side error:. Patch from Per Hedeland.
Fix printing of 8 bit characters as octals in log messages.
Based on patch by Andrey J. Melnikoff.
Undo change of algorithm for MIME 7-bit base64 encoding to 8-bit
text that has been introduced in 8.12.3. There are some
examples where the new code fails, but the old code works.
To get the 8.12.3-8.12.10 version, compile sendmail with
-DMIME7TO8_OLD=0. If you have an example of improper
7 to 8 bit conversion please send it to us.
Return normal error code for unknown SMTP commands instead of
the one specified by check_relay or a milter for a
connection. Problem noted by Andrzej Filip.
Some ident responses contain data after the terminating CRLF which
causes sendmail to log "POSSIBLE ATTACK...newline in string".
To avoid this everything after LF is ignored.
If the operating system supports O_EXLOCK and HASFLOCK is set
then a possible race condition for creating qf files
can be avoided. Note: the race condition does not
exist within sendmail, but between sendmail and an
external application that accesses qf files.
Log the proper options name for TLS related mising files for
the CACertPath, CACertFile, and DHParameters options.
Do not split an envelope if it will be discarded, otherwise df
files could be left behind. Problem found by Wolfgang
Breyha.
The use of the environment variables HOME and HOSTALIASES has been
deprecated and will be removed in version 8.13. This only
effects configuration which preserve those variable via the
'E' command in the cf file as sendmail clears out its entire
environment.
Portability:
Add support for Darwin 7.0/Mac OS X 10.3 (a.k.a. Panther).
Solaris 10 has unsetenv(), patch from Craig Mohrman of
Sun Microsystems.
LIBMILTER: Add extra checks in case a broken MTA sends bogus data
to libmilter. Based on code review by Rob Grzywinski.
SMRSH: Properly assemble commands that contain '&&' or '||'.

SECURITY: Fix a buffer overflow in address parsing. Problem
detected by Michal Zalewski, patch from Todd C. Miller
of Courtesan Consulting.
Fix a potential buffer overflow in ruleset parsing. This problem
is not exploitable in the default sendmail configuration;
only if non-standard rulesets recipient (2), final (4), or
mailer-specific envelope recipients rulesets are used then
a problem may occur. Problem noted by Timo Sirainen.
Accept 0 (and 0/0) as valid input for set MaxMimeHeaderLength.
Problem noted by Thomas Schulz.
Add several checks to avoid (theoretical) buffer over/underflows.
Properly count message size when performing 7->8 or 8->7 bit MIME
conversions. Problem noted by Werner Wiethege.
Properly compute message priority based on size of entire message,
not just header. Problem noted by Axel Holscher.
Reset SevenBitInput to its configured value between SMTP
transactions for broken clients which do not properly
announce 8 bit data. Problem noted by Stefan Roehrich.
Set {addr_type} during queue runs when processing recipients.
Based on patch from Arne Jansen.
Better error handling in case of (very unlikely) queue-id conflicts.
Perform better error recovery for address parsing, e.g., when
encountering a comment that is too long. Problem noted by
Tanel Kokk, Union Bank of Estonia.
Add ':' to the allowed character list for bogus HELO/EHLO
checking. It is used for IPv6 domain literals. Patch from
Iwaizako Takahiro of FreeBit Co., Ltd.
Reset SASL connection context after a failed authentication attempt.
Based on patch from Rob Siemborski of CMU.
Check Berkeley DB compile time version against run time version
to make sure they match.
Do not attempt AAAA (IPv6) DNS lookups if IPv6 is not enabled
in the kernel.
When a milter adds recipients and one of them causes an error,
do not ignore the other recipients. Problem noted by
Bart Duchesne.
CONFIG: Use specified SMTP error code in mailertable entries which
lack a DSN, i.e., "error:### Text". Problem noted by
Craig Hunt.
CONFIG: Call Local_trust_auth with the correct argument. Patch
from Jerome Borsboom.
CONTRIB: Better handling of temporary filenames for doublebounce.pl
and expn.pl to avoid file overwrites, etc. Patches from
Richard A. Nelson of Debian and Paul Szabo.
MAIL.LOCAL: Fix obscure race condition that could lead to an
improper mailbox truncation if close() fails after the
mailbox is fsync()'ed and a new message is delivered
after the close() and before the truncate().
MAIL.LOCAL: If mail delivery fails, do not leave behind a
stale lockfile (which is ignored after the lock timeout).
Patch from Oleg Bulyzhin of Cronyx Plus LLC.
Portability:
Port for AIX 5.2. Thanks to Steve Hubert of University
of Washington for providing access to a computer
with AIX 5.2.
setreuid(2) works on OpenBSD 3.3. Patch from
Todd C. Miller of Courtesan Consulting.
Allow for custom definition of SMRSH_CMDDIR and SMRSH_PATH
on all operating systems. Patch from Robert Harker
of Harker Systems.
Use strerror(3) on Linux. If this causes a problem on
your Linux distribution, compile with
-DHASSTRERROR=0 and tell sendmail.org about it.

8.12.9/8.12.9 2003/03/29
SECURITY: Fix a buffer overflow in address parsing due to
a char to int conversion problem which is potentially
remotely exploitable. Problem found by Michal Zalewski.
Note: an MTA that is not patched might be vulnerable to
data that it receives from untrusted sources, which
includes DNS.
To provide partial protection to internal, unpatched sendmail MTAs,
8.12.9 changes by default (char)0xff to (char)0x7f in
headers etc. To turn off this conversion compile with
-DALLOW_255 or use the command line option -d82.101.
To provide partial protection for internal, unpatched MTAs that may be
performing 7->8 or 8->7 bit MIME conversions, the default
for MaxMimeHeaderLength has been changed to 2048/1024.
Note: this does have a performance impact, and it only
protects against frontal attacks from the outside.
To disable the checks and return to pre-8.12.9 defaults,
set MaxMimeHeaderLength to 0/0.
Do not complain about -ba when submitting mail. Problem noted
by Derek Wueppelmann.
Fix compilation with Berkeley DB 1.85 on systems that do not
have flock(2). Problem noted by Andy Harper of Kings
College London.
Properly initialize data structure for dns maps to avoid various
errors, e.g., looping processes. Problem noted by
Maurice Makaay of InterNLnet B.V.
CONFIG: Prevent multiple application of rule to add smart host.
Patch from Andrzej Filip.
CONFIG: Fix queue group declaration in MAILER(`usenet').
CONTRIB: buildvirtuser: New option -t builds the virtusertable
text file instead of the database map.
Portability:
Revert wrong change made in 8.12.7 and actually use the
builtin getopt() version in sendmail on Linux.
This can be overridden by using -DSM_CONF_GETOPT=0
in which case the OS supplied version will be used.
8.12.8/8.12.8 2003/02/11
SECURITY: Fix a remote buffer overflow in header parsing by
dropping sender and recipient header comments if the
comments are too long. Problem noted by Mark Dowd
of ISS X-Force.
Fix a potential non-exploitable buffer overflow in parsing the
.cf queue settings and potential buffer underflow in
parsing ident responses. Problem noted by Yichen Xie of
Stanford University Compilation Group.
Fix ETRN #queuegroup command: actually start a queue run for
the selected queue group. Problem noted by Jos Vos.
If MaxMimeHeaderLength is set and a malformed MIME header is fixed,
log the fixup as "Fixed MIME header" instead of "Truncated
MIME header". Problem noted by Ian J Hart.
CONFIG: Fix regression bug in proto.m4 that caused a bogus
error message: "FEATURE() should be before MAILER()".
MAIL.LOCAL: Be more explicit in some error cases, i.e., whether
a mailbox has more than one link or whether it is not
a regular file. Patch from John Beck of Sun Microsystems.
8.12.7/8.12.7 2002/12/29
Properly clean up macros to avoid persistence of session data
across various connections. This could cause session
oriented restrictions, e.g., STARTTLS requirements,
to erroneously allow a connection. Problem noted
by Tim Maletic of Priority Health.
Do not lookup MX records when sorting the MSP queue. The MSP
only needs to relay all mail to the MTA. Problem found
by Gary Mills of the University of Manitoba.
Do not restrict the length of connection information to 100
characters in some logging statements. Problem noted by
Erik Parker.
When converting an enhanced status code to an exit status, use
EX_CONFIG if the first digit is not 2, 4, or 5 or if *.1.5
is used.
Reset macro $x when receiving another MAIL command. Problem
noted by Vlado Potisk of Wigro s.r.o.
Don't bother setting the permissions on the build area statistics
file, the proper permissions will be put on the file at
install time. This fixes installation over NFS for some
users. Problem noted by Martin J. Dellwo of 3-Dimensional
Pharmaceuticals, Inc.
Fix problem of decoding SASLv2 encrypted data. Problem noted by
Alex Deiter of Mobile TeleSystems, Komi Republic.
Log milter socket open errors at MilterLogLevel 1 or higher instead
of 11 or higher.
Print early system errors to the console instead of silently
exiting. Problem noted by James Jong of IBM.
Do not process a queue group if Runners is set to 0, regardless
of whether F=f or sendmail is run in verbose mode (-v).
The use of -qGname will still force queue group "name"
to be run even if Runners=0.
Change the level for logging the fact that a daemon is refusing
connections due to high load from LOG_INFO to LOG_NOTICE.
Patch from John Beck of Sun Microsystems.
Use location information for submit.cf from NetInfo
(/locations/sendmail/submit.cf) if available.
Re-enable ForkEachJob which was lost in 8.12.0. Problem noted by
Neil Rickert of Northern Illinois University.
Make behavior of /canon in debug mode consistent with usage in
rulesets. Patch from Shigeno Kazutaka of IIJ.
Fix a potential memory leak in envelope splitting. Problem noted
by John Majikes of IBM.
Do not try to share an mailbox database LDAP connection across
different processes. Problem noted by Randy Kunkee.
Fix logging for undelivered recipients when the SMTP connection
times out during message collection. Problem noted by Neil
Rickert of Northern Illinois University.
Avoid problems with QueueSortOrder=random due to problems with
qsort() on Solaris (and maybe some other operating systems).
Problem noted by Stephan Schulz of Gruner+Jahr..
If -f "" is specified, set the sender address to "<>". Problem
noted by Matthias Andree.
Fix formatting problem of footnotes for plain text output on some
versions of tmac. Patch from Per Hedeland.
Portability:
Berkeley DB 4.1 support (requires at least 4.1.25).
Some getopt(3) implementations in GNU/Linux are broken
and pass a NULL pointer to an option which requires
an argument, hence the builtin version of
sendmail is used instead. This can be overridden
by using -DSM_CONF_GETOPT=0. Problem noted by
Vlado Potisk of Wigro s.r.o.
Support for nph-1.2.0 from Mark D. Roth of the University
of Illinois at Urbana-Champaign.
Support for FreeBSD 5.0's MAC labeling from Robert Watson

CONFIG: Enforce tls_client restrictions even if delay_checks
is used. Problem noted by Malte Starostik.
CONFIG: Deal with an empty hostname created via bogus
DNS entries to get around access restrictions.
Problem noted by Kai Schlichting.
CONFIG: Use FEATURE(`msp', `[127.0.0.1]') in submit.mc by default
to avoid problems with hostname resolution for localhost
which on many systems does not resolve to 127.0.0.1 (or
::1 for IPv6). If you do not use IPv4 but only IPv6 then
you need to change submit.mc accordingly, see the comment
in the file itself.
CONFIG: Set confDONT_INIT_GROUPS to True in submit.mc to avoid
error messages from initgroups(3) on AIX 4.3 when sending
mail to non-existing users. Problem noted by Mark Roth of
the University of Illinois at Urbana-Champaign.
CONFIG: Allow local_procmail to override local_lmtp settings.
CONFIG: Always allow connections from 127.0.0.1 or IPv6:::1 to
relay.

Do not send a bounce message if a message is completely collected
from the SMTP client. Problem noted by Kari Hurtta of the
Finnish Meteorological Institute.
Provide an 'install-submit-st' target for sendmail/Makefile to
install the MSP statistics file using the file named in the
confMSP_STFILE devtools variable. Requested by Jeff
Earickson of Colby College.
Queue up mail with a temporary error if setusercontext() fails
during a delivery attempt. Patch from Todd C. Miller of
Courtesan Consulting.
Fix handling of base64 encoded client authentication data for
SMTP AUTH. Patch from Elena Slobodnik of life medien GmbH.

Prevent a segmentation fault if a program passed a NULL envp using
execve().
Document a problem with the counting of queue runners that may
cause delays if MaxQueueChildren is set too low. Problem
noted by Ian Duplisse of Cable Television Laboratories, Inc.
If discarding a message based on a recipient, don't try to look up
the recipient in the mailbox database if F=w is set. This
allows users to discard bogus recipients when dealing with
spammers without tipping them off. Problem noted by Neil
Rickert of Northern Illinois University.
If applying a header check to a header with unstructured data,
e.g., Subject:, then do not run syntax checks that are
supposed for addresses on the header content.
Count messages rejected/discarded via the check_data ruleset.
Portability:
Fix compilation on systems which do not allow simple
copying of the variable argument va_list. Based on
fix from Scott Walters.
Fix NSD map open bug. From Michel Bourget of SGI.
Add some additional IRIX shells to the default shell
list. From Michel Bourget of SGI.
Fix compilation issues on Mac OS X 10.2 (Darwin 6.0).
NETISO support has been dropped.
CONFIG: There was a seemingly minor change in 8.12.4 with respect
to handling entries of IP nets/addresses with RHS REJECT.
These would be rejected in check_rcpt instead of only
being activated in check_relay. This change has been made to
avoid potential bogus temporary rejection of relay attempts
"450 4.7.1 Relaying temporarily denied. Cannot resolve PTR
record for ..." if delay_checks is enabled. However, this
modification causes a change of behavior if an IP net/address
is listed in the access map with REJECT and a host/domain
name is listed with OK or RELAY, hence it has been reversed
such that the behavior of 8.12.3 is restored. The original
change was made on request of Neil Rickert of Northern
Illinois University, the side effect has been found by
Stefaan Van Hoornick.
CONFIG: Make sure delay_checks works even for sender addresses
using the local hostname ($j) or domains in class {P}.
Based on patch from Neil Rickert of Northern Illinois
University.
CONFIG: Fix temporary error handling for LDAP Routing lookups.
Fix from Andrzej Filip.
CONTRIB: New version of etrn.pl script and external man page

SECURITY: The DNS map can cause a buffer overflow if the user
specifies a dns map using TXT records in the configuration
file and a rogue DNS server is queried. None of the
sendmail supplied configuration files use this option hence
they are not vulnerable. Problem noted independently by
Joost Pol of PINE Internet and Anton Rang of Sun Microsystems.
Unprintable characters in responses from DNS servers for the DNS
map type are changed to 'X' to avoid potential problems
with rogue DNS servers.
Require a suboption when setting the Milter option. Problem noted

Portability:
Include paths.h on Linux systems running glibc 2.0 or later
to get the definition for _PATH_SENDMAIL, used by
rmail and vacation. Problem noted by Kevin
A. McGrail of Peregrine Hardware.
NOTE: Linux appears to have broken flock() again. Unless
the bug is fixed before sendmail 8.13 is shipped,
8.13 will change the default locking method to
fcntl() for Linux kernel 2.4 and later. You may
want to do this in 8.12 by compiling with
-DHASFLOCK=0. Be sure to update other sendmail
related programs to match locking techniques.
8.12.4/8.12.4 2002/06/03
SECURITY: Inherent limitations in the UNIX file locking model
can leave systems open to a local denial of service
attack. Be sure to read the "FILE AND MAP PERMISSIONS"
section of the top level README for more information.
Problem noted by lumpy.
Use TempFileMode (defaults to 0600) for the permissions of PidFile
instead of 0644.
Change the default file permissions for new alias database files
from 0644 to 0640. This can be overridden at compile time
by setting the DBMMODE macro.
Fix a potential core dump problem if the environment variable

CONFIG: FEATURE(`preserve_luser_host') needs the macro map.
Problem noted by Andrzej Filip.
CONFIG: Using 'local:' as a mailertable value with
FEATURE(`preserve_luser_host') and LUSER_RELAY caused mail
to be misaddressed. Problem noted by Andrzej Filip.
CONFIG: Provide a workaround for DNS based rejection lists that
fail for AAAA queries. Problem noted by Chris Boyd.
CONFIG: Accept the machine's hostname as resolvable when checking
the sender address. This allows locally submitted mail to
be accepted if the machine isn't connected to a nameserver
and doesn't have an /etc/hosts entry for itself. Problem
noted by Robert Watson of the TrustedBSD Project.
CONFIG: Use deferred expansion for checking the ${deliveryMode}
macro in case the SMTP VERB command is used. Problem
noted by Bryan Costales.
CONFIG: Avoid a duplicate '@domain' virtusertable lookup if no

VACATION: When listing the vacation database (-l), don't show
bogus timestamps for excluded (-x) addresses. Problem
noted by Bryan Costales.
New Files:
cf/mailer/cyrusv2.m4
8.12.3/8.12.3 2002/04/05
NOTICE: In general queue files should not be moved if queue groups
are used. In previous versions this could cause mail
not to be delivered if a queue file is repeatedly moved
by an external process whenever sendmail moved it back
into the right place. Some precautions have been taken
to avoid moving queue files if not really necessary.
sendmail may use links to refer to queue files and it
may store the path of data files in queue files. Hence
queue files should not be moved unless those internals
are understood and the integrity of the files is not
compromised. Problem noted by Anne Bennett of Concordia
University.
If an error mail is created, and the mail is split across different
queue directories, and SuperSafe is off, then write the mail
to disk before splitting it, otherwise an assertion is
triggered. Problem tracked down by Henning Schmiedehausen
of INTERMETA.
Fix possible race condition that could cause sendmail to forget
running queues. Problem noted by Jeff Wasilko of smoe.org.
Handle bogus qf files better without triggering assertions.
Problem noted by Guy Feltin.
Protect against interrupted select() call when enforcing Milter
read and write timeouts. Patch from Gurusamy Sarathy of
ActiveState.
Matching queue IDs with -qI should be case sensitive. Problem

Northern Illinois University.
Fix SafeFileEnvironment path munging when the specified path
contains a trailing slash. Based on patch from Dirk Meyer
of Dinoex.
Do not limit sendmail command line length to SM_ARG_MAX (usually
4096). Problem noted by Allan E Johannesen of Worcester
Polytechnic Institute.
Clear full name of sender for each new envelope to avoid bogus data
if several mails are sent in one session and some of them
do not have a From: header. Problem noted by Bas Haakman.
Change timeout check such that cached information about a connection
will be immediately invalid if ConnectionCacheTimeout is zero.
Based on patch from David Burns of Portland State University.

Prevent a file descriptor leak on mail delivery if the initial
connect fails and DialDelay is set. Patch from Servaas
Vandenberghe of Katholieke Universiteit Leuven.
Properly deal with a case where sendmail is called by root running
a set-user-ID (non-root) program. Problem noted by Jon
Lusky of ISS Atlanta.
Avoid leaving behind stray transcript (xf) files if multiple queue
directories are used and mail is sent to a mailing list
which has an owner- alias. Problem noted by Anne Bennett
of Concordia University.
Fix class map parsing code if optional key is specified. Problem
found by Mario Nigrovic.
The SMTP daemon no longer tries to fix up improperly dot-stuffed
incoming messages. A leading dot is always stripped by the
SMTP receiver regardless of whether or not it is followed by
another dot. Problem noted by Jordan Ritter of darkridge.com.
Fix corruption when doing automatic MIME 7-bit quoted-printable or
base64 encoding to 8-bit text. Problem noted by Mark
Elvers.
Correct the statistics gathered for total number of connections.
Instead of being the exact same number as the total number
of messages (T line in mailstats) it now represents the
total number of TCP connections.
Be more explicit about syntax errors in addresses, especially
non-ASCII characters, and properly create DSNs if necessary.
Problem noted by Leena Heino of the University of Tampere.
Prevent small timeouts from being lost on slow machines if itimers
are used. Problem noted by Suresh Ramasubramanian.
Prevent a race condition on child cleanup for delivery to files.
Problem noted by Fletcher Mattox of the University of
Texas.
Change the SMTP error code for temporary map failures from 421
to 451.
Do not assume that realloc(NULL, size) works on all OS (this was
only done in one place: queue group creation). Based on
patch by Bryan Costales.
Initialize Timeout.iconnect in the code to prevent randomly short
timeouts. Problem noted by Bradley Watts of AT&T Canada.
Do not try to send a second SMTP QUIT command if the remote
responds to a MAIL command with a 421 reply or on I/O
errors. By doing so, the host was marked as having a
temporary problem and other mail destined for that host was
queued for the next queue run. Problem noted by Fletcher
Mattox of the University of Texas, Allan E Johannesen of
Worcester Polytechnic Institute, Larry Greenfield of CMU,
and Neil Rickert of Northern Illinois University.
Ignore error replies from the SMTP QUIT command (including servers
which drop the connection instead of responding to the
command).
Portability:
Check LDAP_API_VERSION to determine if ldap_memfree() is

Preliminary support for the sparc64 port of FreeBSD 5.0.
Add /sbin/sh as an acceptable user shell on HP-UX. From
Rajesh Somasund of Hewlett-Packard.
CONFIG: Add FEATURE(`authinfo') to allow a separate database for
SMTP AUTH information. This feature was actually added in
8.12.0 but a release note was not included.
CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce
parameter is set and the LDAP lookup returns a temporary
error.
CONFIG: Honor FEATURE(`relay_hosts_only') when using
FEATURE(`relay_mail_from', `domain'). Problem noted by
Krzysztof Oledzki.
CONFIG: FEATURE(`msp') now disables any type of alias
initialization as aliases are not needed for the MSP.
CONFIG: Allow users to override RELAY_MAILER_ARGS when FEATURE(`msp')
is in use. Patch from Andrzej Filip.
CONFIG: FEATURE(`msp') uses `[localhost]' as default instead of
`localhost' and turns on MX lookups for the SMTP mailers.
This will only have an effect if a parameter is specified,
i.e., an MX lookup will be performed on the hostname unless
it is embedded in square brackets. Problem noted by
Theo Van Dinter of Collective Technologies.
CONFIG: Set confTIME_ZONE to USE_TZ in submit.mc (TimeZoneSpec= in
submit.cf) to use $TZ for time stamps. This is a compromise
to allow for the proper time zone on systems where the
default results in misleading time stamps. That is, syslog
time stamps and Date headers on submitted mail will use the
user's $TZ setting. Problem noted by Mark Roth of the
University of Illinois at Urbana-Champaign, solution proposed
by Neil Rickert of Northern Illinois University.
CONFIG: Mac OS X (Darwin) ships with mail.local as non-set-user-ID
binary. Adjust local mailer flags accordingly. Problem
noted by John Beck.
CONTRIB: Add a warning to qtool.pl to not move queue files around
if queue groups are used.

Suggested by Bryan Costales.
DEVTOOLS: Add dependency generation for test programs.
LIBMILTER: Remove conversion of port number for the socket
structure that is passed to xxfi_connect(). Notice:
this fix requires that sendmail and libmilter both have
this change; mixing versions may lead to wrong port
values depending on the endianness of the involved systems.
Problem noted by Gisle Aas of ActiveState.
LIBMILTER: If smfi_setreply() sets a custom reply code of '4XX' but
SMFI_REJECT is returned, ignore the custom reply. Do the
same if '5XX' is used and SMFI_TEMPFAIL is returned.
LIBMILTER: Install include files in ${INCLUDEDIR}/libmilter/ as
required by mfapi.h. Problem noted by Jose Marcio Martins
da Cruz of Ecole Nationale Superieure des Mines de Paris.
LIBSM: Add SM_CONF_LDAP_MEMFREE as a configuration define. Set
this to 1 if your LDAP client libraries include
ldap_memfree().
LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X

Avoid memory corruption problems resulting from bogus .cf files.
Problem found by Michal Zalewski.
Set the ${server_addr} macro to name of mailer when doing LMTP

Continue dealing with broken nameservers by ignoring SERVFAIL
errors returned on T_AAAA (IPv6) lookups at delivery time
if ResolverOptions=WorkAroundBrokenAAAA is set. Previously
this only applied to hostname canonification. Problem
noted by Bill Fenner of AT&T Research.
Ignore comments in NIS host records when trying to find the
canonical name for a host.
When sendmail has extra privileges, limit mail submission command
line flags (i.e., -G, -h, -F, etc.) to mail submission
operating modes (i.e., -bm, -bs, -bv, etc.). Idea based on
suggestion from Michal Zalewski.

*NOTICE*: The default installation of sendmail does not use
set-user-ID root anymore. You need to create a new user and
a new group before installing sendmail (both called smmsp by
default). The installation process tries to install
/etc/mail/submit.cf and creates /var/spool/clientmqueue by
default. Please see sendmail/SECURITY for details.
SECURITY: Check for group and world writable forward and :include:
files. These checks can be turned off if absolutely
necessary using the DontBlameSendmail option and the new
flags:
GroupWritableForwardFile
WorldWritableForwardFile
GroupWritableIncludeFile
WorldWritableIncludeFile
Problem noted by Slawek Zak of Politechnika Warszawska,
SECURITY: Drop privileges when using address test mode. Suggested
by Michal Zalewski of the "Internet for Schools" project
(IdS).
Fixed problem of a global variable being used for a timeout jump
point where the variable could become overused for more than
one timeout concurrently. This erroneous behavior resulted in
a corrupted stack causing a core dump. The timeout is now
handled via libsm. Problem noted by Michael Shapiro,
John Beck, and Carl Smith of Sun Microsystems.
If sendmail is set-group-ID then that group ID is used for permission
checks (group ID of RunAsUser). This allows use of a
set-group-ID sendmail binary for initial message submission
and no set-user-ID root sendmail is needed. For details
see sendmail/SECURITY.
Log a warning if a non-trusted user changes the syslog label.
Based on notice from Bryan Costales of SL3D, Inc.
If sendmail is called for initial delivery, try to use submit.cf
with a fallback of sendmail.cf as configuration file. See
sendmail/SECURITY.
New configuration file option UseMSP to allow group writable queue
files if the group is the same as that of a set-group-ID
sendmail binary. See sendmail/SECURITY.
The .cf file is chosen based on the operation mode. For -bm (default),
-bs, and -t it is submit.cf if it exists for all others it
is sendmail.cf (to be backward compatible). This selection
can be changed by the new option -Ac or -Am (alternative .cf
file: client or mta). See sendmail/SECURITY.
The SMTP server no longer forks on each MAIL command. The ONEX
command has been removed.
Implement SMTP PIPELINING per RFC 2920. It can be turned off
at compile time or per host (ruleset).
New option MailboxDatabase specifies the type of mailbox database
used to look up local mail recipients; the default value
is "pw", which means to use getpwnam(). New mailbox database
types can be added by adding custom code to libsm/mbdb.c.
Queue file names are now 15 characters long, rather than 14 characters
long, to accommodate envelope splitting. File systems with
a 14 character file name length limit are no longer
supported.
Recipient list used for delivery now gets internally ordered by
hostsignature (character string version of MX RR). This orders
recipients for the same MX RR's together meaning smaller
portions of the list need to be scanned (instead of the whole
list) each delivery() pass to determine piggybacking. The
significance of the change is better the larger the recipient
list. Hostsignature is now created during recipient list
creation rather than just before delivery.
Enhancements for more opportunistic piggybacking. Previous
piggybacking (called coincidental) extended to coattail
piggybacking. Rather than complete MX RR matching
(coincidental) piggybacking is done if just the lowest value
preference matches (coattail).
If sendmail receives a temporary error on a RCPT TO: command, it will
try other MX hosts if available.
DefaultAuthInfo can contain a list of mechanisms to be used for
outgoing (client-side) SMTP Authentication.
New modifier 'A' for DaemonPortOptions/ClientPortOptions to disable
AUTH (overrides 'a' modifier in DaemonPortOptions). Based
on patch from Lyndon Nerenberg of Messaging Direct.
Enable AUTH mechanism EXTERNAL if STARTTLS is used.
A new ruleset authinfo can be used to return client side
authentication information for AUTH instead of DefaultAuthInfo.
Therefore the DefaultAuthInfo option is deprecated and will be
removed in future versions.
Accept any SMTP continuation code 3xy for AUTH even though RFC 2554
requires 334. Mercury 1.48 is a known offender.
Add new option AuthMaxBits to limit the overall encryption strength
for the security layer in SMTP AUTH (SASL). See
doc/op/op.me for details.
Introduce new STARTTLS related macros {cn_issuer}, {cn_subject},
{cert_md5} which hold the CN (common name) of the CA that
signed the presented certificate, the CN and the MD5 hash
of the presented certificate, respectively.
New ruleset try_tls to decide whether to try (as client) STARTTLS.
New ruleset srv_features to enable/disable certain features in the
server per connection. See doc/op/op.me for details.
New ruleset tls_rcpt to decide whether to send e-mail to a particular
recipient; useful to decide whether a connection is secure
enough on a per recipient basis.
New option TLSSrvOptions to modify some aspects of the server
for STARTTLS.
If no certificate has been requested, the macro {verify} has the
value "NOT".
New M=S modifier for ClientPortOptions/DaemonPortOptions to turn off
using/offering STARTTLS when delivering/receiving e-mail.
Macro expand filenames/directories for certs and keys in the .cf file.
Proposed by Neil Rickert of Northern Illinois University.
Generate an ephemeral RSA key for a STARTTLS connection only if
really required. This change results in a noticeable
performance gains on most machines. Moreover, if shared
memory is in use, reuse the key several times.
Add queue groups which can be used to group queue directories with
the same behavior together. See doc/op/op.me for details.
If the new option FastSplit (defaults to one) has a value greater
than zero, it suppresses the MX lookups on addresses when they
are initially sorted which may result in faster envelope
splitting. If the mail is submitted directly from the
command line, then the value also limits the number of
processes to deliver the envelopes; if more envelopes are
created they are only queued up and must be taken care of
by a queue run.
The check for 'enough disk space' now pays attention to which file
system each queue directory resides in.
All queue runners can be cleanly terminated via SIGTERM to parent.
New option QueueFileMode for the default permissions of queue files.
Add parallel queue runner code. Allows multiple queue runners per work
group (one or more queues in a multi-queue environment
collected together) to process the same work list at the
same time.
Option MaxQueueChildren added to limit the number of concurrently
active queue runner processes.
New option MaxRunnersPerQueue to specify the maximum number of queue
runners per queue group.
Queue member selection by substring pattern matching now allows
the pattern to be negated. For -qI, -qR and -qS it is
permissible for -q!I, -q!R and -q!S to mean remove members
of the queue that match during processing.
New -qp[time] option is similar to -qtime, except that instead of
periodically forking a child to process the queue, a single
child is forked for each queue that sleeps between queue
runs. A SIGHUP signal can be sent to restart this
persistent queue runner.
The SIGHUP signal now restarts a timed queue run process (i.e., a
sendmail process which only runs the queue at an interval:
sendmail -q15m).
New option NiceQueueRun to set the priority of queue runners.
Proposed by Thom O'Connor.
sendmail will run the queue(s) in the background when invoked with -q
unless the new -qf option or -v is used.
QueueSortOrder=Random sorts the queue randomly, which is useful if
several queue runners are started by hand to avoid contention.
QueueSortOrder=Modification sorts the queue by the modification time
of the qf file (older entries first).
Support Deliver By SMTP Service Extension (RFC 2852) which allows
a client to specify an amount of time within which an e-mail
should be delivered. New option DeliverByMin added to set the
minimum amount of time or disable the extension.
Non-printable characters (ASCII: 0-31, 127) in mailbox addresses are
not allowed unless escaped or quoted.
Add support for a generic DNS map. Based on a patch contributed
by Leif Johansson of Stockholm University, which was based on
work by Assar Westerlund of Swedish Institute of Computer
Science, Kista, and Johan Danielsson of Royal Institute of
Technology, Stockholm, Sweden.
MX records will be looked up for FallBackMXhost. To use the old
behavior (no MX lookups), put the name in square brackets.
Proposed by Thom O'Connor.
Use shared memory to store free space of filesystems that are used
for queues, if shared memory is available and if a key is set
via SharedMemoryKey. This minimizes the number of system
calls to check the available space. See doc/op/op.me for
details.
If shared memory is compiled in the option -bP can be used to print
the number of entries in the queue(s).
Enable generic mail filter API (milter). See libmilter/README
and the usual documentation for details.
Remove AutoRebuildAliases option, deprecated since 8.10.
Remove '-U' (initial user submission) command line option as
announced in 8.10.
Remove support for non-standard SMTP command XUSR. Use an MSA instead.
New macro {addr_type} which contains whether the current address is
an envelope sender or recipient address. Suggested by
Neil Rickert of Northern Illinois University.
Two new options for host maps: -d (retransmission timeout),
-r (number of retries).
New option for LDAP maps: the -V<sep> allows you to specify a
separator such that a lookup can return both an attribute
and value separated by the given separator.
Add new operators '%', '|', '&' (modulo, binary or, binary and)
to map class arith.
If DoubleBounceAddress expands to an empty string, ``double bounces''
(errors that occur when sending an error message) are dropped.
New DontBlameSendmail options GroupReadableSASLDBFile and
GroupWritableSASLDBFile to relax requirements for sasldb files.
New DontBlameSendmail options GroupReadableKeyFile to relax
requirements for files containing secret keys. This is
necessary for the MSP if client authentification is used.
Properly handle quoted filenames for class files (to allow for
filenames with spaces).
Honor the resolver option RES_NOALIASES when canonifying hostnames.
Add macros to avoid the reuse of {if_addr} etc:
{if_name_out} hostname of interface of outgoing connection.
{if_addr_out} address of interface of outgoing connection.
{if_family_out} family of interface of outgoing connection.
The latter two are only set if the interface does not belong
to the loopback net.
Add macro {nrcpts} which holds the number of (validated) recipients.
DialDelay option applies only to mailers with flag 'Z'. Patch from
Juergen Georgi of RUS University of Stuttgart.
New Timeout.lhlo,auth,starttls options to limit the time waiting for
an answer to the LMTP LHLO, SMTP AUTH or STARTTLS command.
New Timeout.aconnect option to limit the overall waiting time for
all connections for a single delivery attempt to succeed.
Limit the rate recipients in the SMTP envelope are accepted once
a threshold number of recipients has been rejected (option
BadRcptThrottle). From Gregory A Lundberg of the WU-FTPD
Development Group.
New option DelayLA to delay connections if the load averages
exceeds the specified value. The default of 0 does not
change the previous behavior. A value greater than 0
will cause sendmail to sleep for one second on most
SMTP commands and before accepting connections if that
load average is exceeded.
Use a dynamic (instead of fixed-size) buffer for the list of
recipients that are sent during a connection to a mailer.
This also introduces a new mailer field 'r' which defines
the maximum number of recipients (defaults to 100).
Based on patch by Motonori Nakamura of Kyoto University.
Add new F=1 mailer flag to disable sending of null characters ('\0').
Add new F=2 mailer flag to disable use of ESMTP, using SMTP instead.
The deprecated [TCP] builtin mailer pathname (P=) is gone. Use [IPC]
instead.
IPC is no longer available as first mailer argument (A=) for [IPC]
builtin mailer pathnames. Use TCP instead.
PH map code updated to use the new libphclient API instead of the
old libqiapi library. Contributed by Mark Roth of the
University of Illinois at Urbana-Champaign.
New option DirectSubmissionModifiers to define {daemon_flags}
for direct (command line) submissions.
New M=O modifier for DaemonPortOptions to ignore the socket in
case of failures. Based on patch by Jun-ichiro itojun
Hagino of the KAME Project.
Add Disposition-Notification-To: (RFC 2298) to the list of headers
whose content is rewritten similar to Reply-To:.
Proposed by Andrzej Filip.
Use STARTTLS/AUTH=server/client for logging incoming/outgoing
STARTTLS/AUTH connections; log incoming connections at level
9 or higher. Use AUTH/STARTTLS instead of SASL/TLS for SMTP
AUTH/STARTTLS related logfile entries.
Convert unprintable characters (and backslash) into octal or C format
before logging.
Log recipients if no message is transferred but QUIT/RSET is given
(at LogLevel 9/10 or higher).
Log discarded recipients at LogLevel 10 or higher.
Do not log "did not issue MAIL/EXPN/VRFY/ETRN" for connections
in which most commands are rejected due to check_relay or
TCP Wrappers if the host tries one of those commands anyway.
Change logging format for cloned envelopes to be similar to that for
DSNs ("old id: new id: clone"). Suggested by Ulrich Windl
of the Universitat Regensburg.
Added libsm, a C library of general purpose abstractions including
assertions, tracing and debugging with named debug categories,
exception handling, malloc debugging, resource pools,
portability abstractions, and an extensible buffered I/O
package. It will at some point replace libsmutil.
See libsm/index.html for details.
Fixed most memory leaks in sendmail which were previously taken
care of by fork() and exit().
Use new sm_io*() functions in place of stdio calls. Allows for
more consistent portablity amongst different platforms
new and old (from new libsm).
Common I/O pkg means just one buffering method needed instead of two
('bf_portable' and 'bf_torek' now just 'bf').
Sfio no longer needed as SASL/TLS code uses sm_io*() API's.
New possible value 'interactive' for SuperSafe which can be used
together with DeliveryMode=interactive is to avoid some disk
synchronizations calls.
Add per-recipient status information to mailq -v output.
T_ANY queries are no longer used by sendmail.
When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS"
too (see include/sm/cdefs.h for more info).
sendmail -d now has general support for named debug categories.
See libsm/debug.html and section 3.4 of doc/op/op.me
for details.
Eliminate the "postmaster warning" DSNs on address parsing errors
such as unbalanced angle brackets or parentheses. The DSNs
generated by this condition were illegal (not RFC conform).
Problem noted by Ulrich Windl of the Universitaet Regensburg.
Do not issue a DSN if the ruleset localaddr resolves to the $#error
mailer and the recipient has hence been rejected during the
SMTP dialogue. Problem reported by Larry Greenfield of CMU.
Deal with a case of multiple deliveries on misconfigured systems
that do not have postmaster defined. If an email was sent
from an address to which a DSN cannot be returned and
in which at least one recipient address is non-deliverable,
then that email had been delivered in each queue run.
Problem reported by Matteo HCE Valsasna of Universita
degli Studi dell'Insubria.
The compilation options SMTP, DAEMON, and QUEUE have been removed,
i.e., the corresponding code is always compiled in now.
Log the command line in daemon/queue-run mode at LogLevel 10 and
higher. Suggested by Robert Harker of Harker Systems.
New ResolverOptions setting: WorkAroundBrokenAAAA. When
attempting to canonify a hostname, some broken nameservers
will return SERVFAIL (a temporary failure) on T_AAAA (IPv6)
lookups. If you want to excuse this behavior, use this new
flag. Suggested by Chris Foote of SE Network Access and
Mark Roth of the University of Illinois at
Urbana-Champaign.
Free the memory allocated by getipnodeby{addr,name}(). Problem
noted by Joy Latten of IBM.
ConnectionRateThrottle limits the number of connections per second
to each daemon individually, not the overall number of
connections.
Specifying only "ldap:" as an AliasFile specification will force
sendmail to use a default alias schema as outlined in the
``USING LDAP FOR ALIASES, MAPS, and CLASSES'' section of
cf/README.
Add a new syntax for the 'F' (file class) sendmail.cf command. If
the first character after the class name is not a '/' or a
'|' and it contains an '@' (e.g., F{X}key@class:spec), the
rest of the line will be parsed as a map lookup. This
allows classes to be filled via a map lookup. See op.me
for more syntax information. Specifically, this can be
used for commands such as VIRTUSER_DOMAIN_FILE() to read
the list of domains via LDAP (see the ``USING LDAP FOR
ALIASES, MAPS, and CLASSES'' section of cf/README for an
example).
The new macro ${sendmailMTACluster} determines the LDAP cluster for
the default schema used in the above two items.
Unless DontBlameSendmail=RunProgramInUnsafeDirPath is set, log a
warning if a program being run from a mailer or file class
(e.g., F|/path/to/prog) is in an unsafe directory path.
Unless DontBlameSendmail=RunWritableProgram is set, log a warning
if a program being run from a mailer or file class
(e.g., F|/path/to/prog) is group or world writable.
Loopback interfaces (e.g., "lo0") are now probed for class {w}
hostnames. Setting DontProbeInterfaces to "loopback"
(without quotes) will disable this and return to the
pre-8.12 behavior of only probing non-loopback interfaces.
Suggested by Bryan Stansell of GNAC.
In accordance with RFC 2821 section 4.1.4, accept multiple
HELO/EHLO commands.
Multiple ClientPortOptions settings are now allowed, one for each
possible protocol family which may be used for outgoing
connections. Restrictions placed on one family only affect
outgoing connections on that particular family. Because of
this change, the ${client_flags} macro is not set until the
connection is established. Based on patch from Motonori
Nakamura of Kyoto University.
PrivacyOptions=restrictexpand instructs sendmail to drop privileges
when the -bv option is given by users who are neither root
nor the TrustedUser so users can not read private aliases,
forwards, or :include: files. It also will override the -v
(verbose) command line option.
If the M=b modifier is set in DaemonPortOptions and the interface
address can't be used for the outgoing connection, fall
back to the settings in ClientPortOptions (if set).
Problem noted by John Beck of Sun Microsystems.
New named config file rule check_data for DATA command (input:
number of recipients). Based on patch from Mark Roth of
the University of Illinois at Urbana-Champaign.
Add support for ETRN queue selection per RFC 1985. The queue group
can be specified using the '#' option character. For
example, 'ETRN #queuegroup'.
If an LDAP server times out or becomes unavailable, close the
current connection and reopen to get to one of the fallback
servers. Patch from Paul Hilchey of the University of
British Columbia.
Make default error number on $#error messages 550 instead of 501
because 501 is not allowed on all commands.
The .cf file option UnsafeGroupWrites is deprecated, it should be
replaced with the settings GroupWritableForwardFileSafe
and GroupWritableIncludeFileSafe in DontBlameSendmail
if required.
The deprecated ldapx map class has been removed. Use the ldap map
class instead.
Any IPv6 addresses used in configuration should be prefixed by the
"IPv6:" tag to identify the address properly. For example,
if you want to add the IPv6 address [2002:c0a8:51d2::23f4] to
class {w}, you would need to add [IPv6:2002:c0a8:51d2::23f4].
Change the $&{opMode} macro if the operation mode changes while the
MTA is running. For example, during a queue run.
Add "use_inet6" as a new ResolverOptions flag to control the
RES_USE_INET6 resolver option. Based on patch from Rick
Nelson of IBM.
The maximum number of commands before the MTA slows down when too
many "light weight" commands have been received are now
configurable during compile time. The current values and
their defaults are:
MAXBADCOMMANDS 25 unknown commands
MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR
MAXHELOCOMMANDS 3 HELO, EHLO
MAXVRFYCOMMANDS 6 VRFY, EXPN
MAXETRNCOMMANDS 8 ETRN
Setting a value to 0 disables the check. Patch from Bryan
Costales of SL3D, Inc.
The header syntax H?${MyMacro}?X-My-Header: now not only checks if
${MyMacro} is defined but also that it is not empty.
Properly quote usernames with special characters if they are used
in headers. Problem noted by Kari Hurtta of the Finnish
Meteorological Institute.
Be sure to include the proper Final-Recipient: DSN header in bounce
messages for messages for mailing list expanded addresses
which are not delivered on the initial attempt.
Do not treat errors as sticky when doing delivery via LMTP after
the final dot has been sent to avoid affecting future
deliveries. Problem reported by Larry Greenfield of CMU.
New compile time flag REQUIRES_DIR_FSYNC which turns on support for
file systems that require to call fsync() for a directory
if the meta-data in it has been changed. This should be
set at least for ReiserFS; it is enabled by default for Linux.
See sendmail/README for further information.
Avoid file locking deadlock when updating the statistics file if
sendmail is signaled to terminate. Problem noted by
Christophe Wolfhugel of France Telecom.
Set the $c macro (hop count) as it is being set instead of when the
envelope is initialized. Problem noted by Kari Hurtta of
the Finnish Meteorological Institute.
Properly count recipients for DeliveryMode defer and queue. Fix
from Peter A. Friend of EarthLink.
Treat invalid hesiod lookups as permanent errors instead of
temporary errors. Problem noted by Russell McOrmond of
flora.ca.
Portability:
Remove support for AIX 2, which supports only 14 character
filenames and is outdated anyway. Suggested by
Valdis Kletnieks of Virginia Tech.
Change several settings for Irix 6: remove confSBINDIR,
i.e., use default /usr/sbin, change owner/group
of man pages and user-executable to root/sys, set
optimization limit to 0 (unlimited). Based on patch
from Ayamura Kikuchi, M.D, and proposal from Kari
Hurtta of the Finnish Meteorological Institute.
Do not assume LDAP support is installed by default under
Solaris 8 and later.
Add support for OpenUNIX.
CONFIG: Increment version number of config file to 10.
CONFIG: Add an install target and a README file in cf/cf.
CONFIG: Don't accept addresses of the form a@b@, a@b@c, a@[b]c, etc.
CONFIG: Reject empty recipient addresses (in check_rcpt).
CONFIG: The access map uses an option of -T<TMPF> to deal with
temporary lookup failures.
CONFIG: New value for access map: SKIP, which causes the default
action to be taken by aborting the search for domain names
or IP nets.
CONFIG: check_rcpt can deal with TEMPFAIL for either recipient or
relay address as long as the other part allows the email
to get through.
CONFIG: Entries for virtusertable can make use of a third parameter
"%3" which contains "+detail" of a wildcard match, i.e., an
entry like user+*@domain. This allows handling of details by
using %1%3 as the RHS. Additionally, a "+" wildcard has been
introduced to match only non-empty details of addresses.
CONFIG: Numbers for rulesets used by MAILERs have been removed
and hence there is no required order within the MAILER
section anymore except for MAILER(`uucp') which must come
after MAILER(`smtp') if uucp-dom and uucp-uudom are used.
CONFIG: Hosts listed in the generics domain class {G}
(GENERICS_DOMAIN() and GENERICS_DOMAIN_FILE()) are treated
as canonical. Suggested by Per Hedeland of Ericsson.
CONFIG: If FEATURE(`delay_checks') is used, make sure that a lookup
in the access map which returns OK or RELAY actually
terminates check_* ruleset checking.
CONFIG: New tag TLS_Rcpt: for access map to be used by ruleset
tls_rcpt, see cf/README for details.
CONFIG: Change format of Received: header line which reveals whether
STARTTLS has been used to "(version=${tls_version}
cipher=${cipher} bits=${cipher_bits} verify=${verify})".
CONFIG: Use "Spam:" as tag for lookups for FEATURE(`delay_checks')
options friends/haters instead of "To:" and enable
specification of whole domains instead of just users.
Notice: this change is not backward compatible.
Suggested by Chris Adams from HiWAAY Informations Services.
CONFIG: Allow for local extensions for most new rulesets, see
cf/README for details.
CONFIG: New FEATURE(`lookupdotdomain') to lookup also .domain in
the access map. Proposed by Randall Winchester of the
University of Maryland.
CONFIG: New FEATURE(`local_no_masquerade') to avoid masquerading for
the local mailer. Proposed by Ingo Brueckl of Wupper Online.
CONFIG: confRELAY_MSG/confREJECT_MSG can override the default
messages for an unauthorized relaying attempt/for access
map entries with RHS REJECT, respectively.
CONFIG: FEATURE(`always_add_domain') takes an optional argument
to specify another domain to be added instead of the local one.
Suggested by Richard H. Gumpertz of Computer Problem
Solving.
CONFIG: confAUTH_OPTIONS allows setting of Cyrus-SASL specific
options, see doc/op/op.me for details.
CONFIG: confAUTH_MAX_BITS sets the maximum encryption strength for
the security layer in SMTP AUTH (SASL).

immediately.
CONFIG: FEATURE(`enhdnsbl') is an enhanced version of dnsbl which
allows checking of the return values of the DNS lookups.
See cf/README for details.
CONFIG: FEATURE(`dnsbl') allows now to specify the behavior for
temporary lookup failures.
CONFIG: New option confDELIVER_BY_MIN to specify minimum time for
Deliver By (RFC 2852) or to turn off the extension.
CONFIG: New option confSHARED_MEMORY_KEY to set the key for shared
memory use.
CONFIG: New FEATURE(`compat_check') to look up a key consisting
of the sender and the recipient address delimited by the
string "<@>", e.g., sender@sdomain<@>recipient@rdomain,
in the access map. Based on code contributed by Mathias
Koerber of Singapore Telecommunications Ltd.
CONFIG: Add EXPOSED_USER_FILE() command to allow an exposed user
file. Suggested by John Beck of Sun Microsystems.
CONFIG: Don't use MAILER-DAEMON for error messages delivered
via LMTP. Problem reported by Larry Greenfield of CMU.
CONFIG: New FEATURE(`preserve_luser_host') to preserve the name of
the recipient host if LUSER_RELAY is used.
CONFIG: New FEATURE(`preserve_local_plus_detail') to preserve the
+detail portion of the address when passing address to
local delivery agent. Disables alias and .forward +detail
stripping. Only use if LDA supports this.
CONFIG: Removed deprecated FEATURE(`rbl').
CONFIG: Add LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE()
which allow you to specify 'equivalent' hosts for LDAP
Routing lookups. Equivalent hostnames are replaced by the
masquerade domain name for lookups. See cf/README for
additional details.
CONFIG: Add a fourth argument to FEATURE(`ldap_routing') which
instructs the rulesets on what to do if the address being
looked up has +detail information. See cf/README for more
information.
CONFIG: When chosing a new destination via LDAP Routing, also look
up the new routing address/host in the mailertable. Based
on patch from Don Badrak of the United States Census Bureau.
CONFIG: Do not reject the SMTP Mail from: command if LDAP Routing
is in use and the bounce option is enabled. Only reject
recipients as user unknown.
CONFIG: Provide LDAP support for the remaining database map
features. See the ``USING LDAP FOR ALIASES AND MAPS''
section of cf/README for more information.
CONFIG: Add confLDAP_CLUSTER which defines the ${sendmailMTACluster}
macro used for LDAP searches as described above in ``USING
LDAP FOR ALIASES, MAPS, AND CLASSES''.
CONFIG: confCLIENT_OPTIONS has been replaced by CLIENT_OPTIONS(),
which takes the options as argument and can be used
multiple times; see cf/README for details.

MAIL_FILTER(). See libmilter/README, cf/README, and
doc/op/op.me for details.
CONFIG: Add support for accepting temporarily unresolvable domains.
See cf/README for details. Based on patch by Motonori
Nakamura of Kyoto University.
CONFIG: confDEQUOTE_OPTS can be used to specify options for the
dequote map.
CONFIG: New macro QUEUE_GROUP() to define queue groups.
CONFIG: New FEATURE(`queuegroup') to select a queue group based
on the full e-mail address or the domain of the recipient.
CONFIG: Any IPv6 addresses used in configuration should be prefixed
by the "IPv6:" tag to identify the address properly. For
example, if you want to use the IPv6 address
2002:c0a8:51d2::23f4 in the access database, you would need
to use IPv6:2002:c0a8:51d2::23f4 on the left hand side.
This affects the access database as well as the
relay-domains and local-host-names files.
CONFIG: OSTYPE(aux) has been renamed to OSTYPE(a-ux).
CONFIG: Avoid expansion of m4 keywords in SMART_HOST.
CONFIG: Add MASQUERADE_EXCEPTION_FILE() for reading masquerading

(LOCAL_USER() -- $={L}) entries from a file.
CONTRIB: dnsblaccess.m4 is a further enhanced version of enhdnsbl.m4
which allows to lookup error codes in the access map.
Contributed by Neil Rickert of Northern Illinois University.
DEVTOOLS: Add new options for installation of include and library
files: confINCGRP, confINCMODE, confINCOWN, confLIBGRP,
confLIBMODE, confLIBOWN.
DEVTOOLS: Add new option confDONT_INSTALL_CATMAN to turn off
installation of the the formatted man pages on operating
systems which don't include cat directories.
EDITMAP: New program for editing maps as supplement to makemap.
MAIL.LOCAL: Mail.local now uses the libsm mbdb package to look up
local mail recipients. New option -D mbdb specifies the
mailbox database type.
MAIL.LOCAL: New option "-h filename" which instructs mail.local to
deliver the mail to the named file in the user's home
directory instead of the system mail spool area. Based on
patch from Doug Hardie of the Los Angeles Free-Net.
MAILSTATS: New command line option -P which acts the same as -p but
doesn't truncate the statistics file.
MAKEMAP: Add new option -t to specify a different delimiter
instead of white space.
RMAIL: Invoke sendmail with '-G' to indicate this is a gateway
submission. Problem noted by Kari Hurtta of the Finnish
Meteorological Institute.
SMRSH: Use the vendor supplied directory on FreeBSD 3.3 and later.
VACATION: Change Auto-Submitted: header value from auto-generated to
auto-replied. From Kenneth Murchison of Oceana Matrix Ltd.
VACATION: New option -d to send error/debug messages to stdout
instead of syslog.
VACATION: New option -U which prevents the attempt to lookup login
in the password file. The -f and -m options must be used
to specify the database and message file since there is no
home directory for the default settings for these options.
VACATION: Vacation now uses the libsm mbdb package to look up
local mail recipients; it reads the MailboxDatabase option
from the sendmail.cf file. New option -C cffile which
specifies the path of the sendmail.cf file.

8.11.7/8.11.7 2003/03/29
SECURITY: Fix a remote buffer overflow in header parsing by
dropping sender and recipient header comments if the
comments are too long. Problem noted by Mark Dowd
of ISS X-Force.
SECURITY: Fix a buffer overflow in address parsing due to
a char to int conversion problem which is potentially
remotely exploitable. Problem found by Michal Zalewski.
Note: an MTA that is not patched might be vulnerable to
data that it receives from untrusted sources, which
includes DNS.
To provide partial protection to internal, unpatched sendmail MTAs,
8.11.7 changes by default (char)0xff to (char)0x7f in
headers etc. To turn off this conversion compile with
-DALLOW_255 or use the command line option -d82.101.
To provide partial protection for internal, unpatched MTAs that may be
performing 7->8 or 8->7 bit MIME conversions, the default
for MaxMimeHeaderLength has been changed to 2048/1024.
Note: this does have a performance impact, and it only
protects against frontal attacks from the outside.
To disable the checks and return to pre-8.11.7 defaults,
set MaxMimeHeaderLength to 0/0.
Properly clean up macros to avoid persistence of session data
across various connections. This could cause session
oriented restrictions, e.g., STARTTLS requirements,
to erroneously allow a connection. Problem noted
by Tim Maletic of Priority Health.
Ignore comments in NIS host records when trying to find the
canonical name for a host.
Fix a memory leak when closing Hesiod maps.
Set ${msg_size} macro when reading a message from the command line
or the queue.
Prevent a segmentation fault when clearing the event list by
turning off alarms before checking if event list is
empty. Problem noted by Allan E Johannesen of Worcester
Polytechnic Institute.
Fix a potential core dump problem if the environment variable
NAME is set. Problem noted by Beth A. Chaney of
Purdue University.
Prevent a race condition on child cleanup for delivery to files.
Problem noted by Fletcher Mattox of the University of
Texas.
CONFIG: Do not bounce mail if FEATURE(`ldap_routing')'s bounce
parameter is set and the LDAP lookup returns a temporary
error.
CONFIG: Fix a syntax error in the try_tls ruleset if
FEATURE(`access_db') is not enabled.
LIBSMDB: Fix a lock race condition that affects makemap, praliases,
and vacation.
LIBSMDB: Avoid a file creation race condition for Berkeley DB 1.X
and NDBM on systems with the O_EXLOCK open(2) flag.
MAKEMAP: Avoid going beyond the end of an input line if it does
not contain a value for a key. Based on patch from
Mark Bixby from Hewlett-Packard.
MAIL.LOCAL: Fix a truncation race condition if the close() on
the mailbox fails. Problem noted by Tomoko Fukuzawa of
Sun Microsystems.
SMRSH: SECURITY: Only allow regular files or symbolic links to be
used for a command. Problem noted by David Endler of
iDEFENSE, Inc.
8.11.6/8.11.6 2001/08/20
SECURITY: Fix a possible memory access violation when specifying
out-of-bounds debug parameters. Problem detected by

check_* rulesets by returning a temporary failure.
Buffered file I/O files were not being properly fsync'ed to disk
when they were committed.
Properly encode '=' for the AUTH= parameter of the MAIL command.
Problem noted by Hadmut Danisch.
Under certain circumstances the macro {server_name} could be set
to the wrong hostname (of a previous connection), which may
cause some rulesets to return wrong results. This would
usually cause mail to be queued up and delivered later on.
Ignore F=z (LMTP) mailer flag if $u is given in the mailer A=

accept() completes.
Return an SMTP "421" temporary failure if the data file can't be
opened where the "354" reply would normally be given.
Prevent a CPU loop in trying to expand a macro which doesn't exist
in a queue run. Problem noted by Gordon Lack of Glaxo
Wellcome.
If delivering via a program and that program exits with EX_TEMPFAIL,

Colby College.
Don't issue DSNs for addresses which use the NOTIFY parameter (per
RFC 1891) but don't have FAILURE as value.
Initialize Cyrus-SASL library before the SMTP daemon is started.
This implies that every change to SASL related files requires

SECURITY: If sendmail is installed as a non-root set-user-ID binary
(not the normal case), some operating systems will still
keep a saved-uid of the effective-uid when sendmail tries
to drop all of its privileges. If sendmail needs to drop
these privileges and the operating system doesn't set the
saved-uid as well, exit with an error. Problem noted by
Kari Hurtta of the Finnish Meteorological Institute.
SECURITY: sendmail depends on snprintf() NUL terminating the string
it populates. It is possible that some broken
implementations of snprintf() exist that do not do this.
Systems in this category should compile with
-DSNPRINTF_IS_BROKEN=1. Use test/t_snprintf.c to test your
system and report broken implementations to
sendmail-bugs@sendmail.org and your OS vendor. Problem
noted by Slawomir Piotrowski of TELSAT GP.
Support SMTP Service Extension for Secure SMTP (RFC 2487) (STARTTLS).
Implementation influenced by the example programs of
OpenSSL and the work of Lutz Jaenicke of TU Cottbus.

Add more protection from accidentally tripping OpenLDAP 1.X's
ld_errno == LDAP_DECODING_ERROR hack on ldap_next_attribute().
Suggested by Kurt Zeilenga of OpenLDAP.
Fix the default family selection for DaemonPortOptions. As
documented, unless a family is specified in a
DaemonPortOptions option, "inet" is the default. It is
also the default if no DaemonPortOptions value is set.
Therefore, IPv6 users should configure additional sockets
by adding DaemonPortOptions settings with Family=inet6 if
they wish to also listen on IPv6 interfaces. Problem noted
by Jun-ichiro itojun Hagino of the KAME Project.
Set ${if_family} when setting ${if_addr} and ${if_name} to reflect
the interface information for an outgoing connection.
Not doing so was creating a mismatch between the socket
family and address used in subsequent connections if the
M=b modifier was set in DaemonPortOptions. Problem noted
by John Beck of Sun Microsystems.
If DaemonPortOptions modifier M=b is used, determine the socket
family based on the IP address. ${if_family} is no longer
persistent (i.e., saved in qf files). Patch from John Beck
of Sun Microsystems.
sendmail 8.10 and 8.11 reused the ${if_addr} and ${if_family}
macros for both the incoming interface address/family and
the outgoing interface address/family. In order for M=b
modifier in DaemonPortOptions to work properly, preserve
the incoming information in the queue file for later
delivery attempts.
Use SMTP error code and enhanced status code from check_relay in

On Linux, a normal user process has the ability to subvert
the setuid() call such that it is impossible for a root
process to drop its privileges. Problem noted by Wojciech

SECURITY: Limit the choice of outgoing (client-side) SMTP
Authentication mechanisms to those specified in
AuthMechanisms to prevent information leakage. We do not
recommend use of PLAIN for outgoing mail as it sends the
password in clear text to possibly untrusted servers. See
cf/README's DefaultAuthInfo section for additional information.
Copy the ident argument for openlog() to avoid problems on some
OSs. Based on patch from Rob Bajorek from Webhelp.com.
Avoid bogus error message when reporting an alias line as too long.
Avoid bogus socket error message if sendmail.cf version level is
greater than sendmail binary supported version. Patch
from John Beck of Sun Microsystems.
Prevent a malformed ruleset (missing right hand side) from causing
a segmentation fault when using address test mode. Based on
patch from John Beck of Sun Microsystems.
Prevent memory leak from use of NIS maps and yp_match(3). Problem
noted by Gil Kloepfer of the University of Texas at Austin.
Fix queue file permission checks to allow for TrustedUser ownership.
Change logging of errors from the trust_auth ruleset to LogLevel 10
or higher.
Avoid simple password cracking attacks against SMTP AUTH by using
exponential delay after too many tries within one connection.
Encode an initial empty AUTH challenge as '=', not as empty string.
Avoid segmentation fault on EX_SOFTWARE internal error logs.
Problem noted by Allan E Johannesen of Worcester
Polytechnic Institute.
Ensure that a header check which resolves to $#discard actually
discards the message.
Emit missing value warnings for aliases with no right hand side
when newaliases is run instead of only when delivery is
attempted to the alias.
Remove AuthOptions missing value warning for consistency with other
flag options.
Portability:
SECURITY: Specify a run-time shared library search path for
AIX 4.X instead of using the dangerous AIX 4.X
linker semantics. AIX 4.X users should consult
sendmail/README for further information. Problem
noted by Valdis Kletnieks of Virginia Tech.
Avoid use of strerror(3) call. Problem noted by Charles
Levert of Ecole Polytechnique de Montreal.
DGUX requires -lsocket -lnsl and has a non-standard install

DEVTOOLS: SECURITY: Change method of linking with sendmail utility
libraries to work around the AIX 4.X and SunOS 4.X linker's
overloaded -L option. Problem noted by Valdis Kletnieks of
Virginia Tech.
DEVTOOLS: configure.sh was overriding the user's choice for
confNROFF. Problem noted by Glenn A. Malling of Syracuse

DEVTOOLS: New variables conf_prog_LIB_POST and confBLDVARIANT added
for other internal projects but included in the open source
release.
LIBSMDB: Check for ".db" instead of simply "db" at the end of the
map name to determine whether or not to add the extension.
This fixes makemap when building the userdb file. Problem
noted by Andrew J Cole of the University of Leeds.
LIBSMDB: Allow a database to be opened for updating and created if
it doesn't already exist. Problem noted by Rand Wacker of
Sendmail.
LIBSMDB: If type is SMDB_TYPE_DEFAULT and both NEWDB and NDBM are
available, fall back to NDBM if NEWDB open fails. This

SECURITY: The safe file checks now back track through symbolic
links to make sure the files can't be compromised due
to poor permissions on the parent directories of the
symbolic link target.
SECURITY: Only root, TrustedUser, and users in class t can rebuild
the alias map. Problem noted by Michal Zalewski of the
"Internet for Schools" project (IdS).
SECURITY: There is a potential for a denial of service attack if
the AutoRebuildAliases option is set as a user can kill the
sendmail process while it is rebuilding the aliases file
(leaving it in an inconsistent state). This option and
its use is deprecated and will be removed from a future
version of sendmail.
SECURITY: Make sure all file descriptors (besides stdin, stdout, and
stderr) are closed before restarting sendmail. Problem noted
by Michal Zalewski of the "Internet for Schools" project
(IdS).
Begin using /etc/mail/ for sendmail related files. This affects
a large number of files. See cf/README for more details.
The directory structure of the distribution has changed slightly
for easier code sharing among the programs.
Support SMTP AUTH (see RFC 2554). New macros for this purpose
are ${auth_authen}, ${auth_type}, and ${auth_author}
which hold the client's authentication credentials,
the mechanism used for authentication, and the
authorization identity (i.e., the AUTH= parameter if
supplied). Based on code contributed by Tim Martin of CMU.
On systems which use the Torek stdio library (all of the BSD
distributions), use memory-buffered files to reduce
file system overhead by not creating temporary files on
disk. Contributed by Exactis.com, Inc.
New option DataFileBufferSize to control the maximum size of a
memory-buffered data (df) file before a disk-based file is
used. Contributed by Exactis.com, Inc.
New option XscriptFileBufferSize to control the maximum size of a
memory-buffered transcript (xf) file before a disk-based
file is used. Contributed by Exactis.com, Inc.
sendmail implements RFC 2476 (Message Submission), e.g., it can
now listen on several different ports. Use:
O DaemonPortOptions=Name=MSA, Port=587, M=E
to run a Message Submission Agent (MSA); this is turned
on by default in m4-generated .cf files; it can be turned
off with FEATURE(`no_default_msa').
The 'XUSR' SMTP command is deprecated. Mail user agents should
begin using RFC 2476 Message Submission for initial user
message submission. XUSR may disappear from a future release.
The new '-G' (relay (gateway) submission) command line option
indicates that the message being submitted from the command
line is for relaying, not initial submission. This means
the message will be rejected if the addresses are not fully
qualified and no canonicalization will be done. Future
releases may even reject improperly formed messages.
The '-U' (initial user submission) command line option is
deprecated and may be removed from a future release.
Mail user agents should begin using '-G' to indicate that
this is a relay submission (the inverse of -U).
The next release of sendmail will assume that any message submitted
from the command line is an initial user submission and act
accordingly.
If sendmail doesn't have enough privileges to run a .forward
program or deliver to file as the owner of that file, the
address is marked as unsafe. This means if RunAsUser is
set, users won't be able to use programs or delivery to
files in their .forward files. Administrators can override
this by setting the DontBlameSendmail option to the new
setting NonRootSafeAddr.
Allow group or world writable directories if the sticky bit is set
on the directory and DontBlameSendmail is set to
TrustStickyBit. Based on patch from Chris Metcalf of
InCert Software.
Prevent logging of unsafe directory paths for non-existent forward
files if the new DontWarnForwardFileInUnsafeDirPath bit is
set in the DontBlameSendmail option. Requested by many.
New Timeout.control option to limit the total time spent satisfying
a control socket request.
New Timeout.resolver options for controlling BIND resolver
settings:
Timeout.resolver.retrans
Sets the resolver's retransmission time interval (in
seconds). Sets both Timeout.resolver.retrans.first
and Timeout.resolver.retrans.normal.
Timeout.resolver.retrans.first
Sets the resolver's retransmission time interval (in
seconds) for the first attempt to deliver a message.
Timeout.resolver.retrans.normal
Sets the resolver's retransmission time interval (in
seconds) for all resolver lookups except the first
delivery attempt.
Timeout.resolver.retry
Sets the number of times to retransmit a resolver
query. Sets both Timeout.resolver.retry.first
and Timeout.resolver.retry.normal.
Timeout.resolver.retry.first
Sets the number of times to retransmit a resolver
query for the first attempt to deliver a message.
Timeout.resolver.retry.normal
Sets the number of times to retransmit a resolver
query for all resolver lookups except the first
delivery attempt.

Support multiple queue directories. To use multiple queues, supply
a QueueDirectory option value ending with an asterisk. For
example, /var/spool/mqueue/q* will use all of the
directories or symbolic links to directories beginning with
'q' in /var/spool/mqueue as queue directories. Keep in
mind, the queue directory structure should not be changed
while sendmail is running. Queue runs create a separate
process for running each queue unless the verbose flag is
given on a non-daemon queue run. New items are randomly
assigned to a queue. Contributed by Exactis.com, Inc.
Support different directories for qf, df, and xf queue files; if
subdirectories or symbolic links to directories of those names
exist in the queue directories, they are used for the
corresponding queue files. Keep in mind, the queue
directory structure should not be changed while sendmail is
running. Proposed by Mathias Koerber of Singapore
Telecommunications Ltd.
New queue file naming system which uses a filename guaranteed to be
unique for 60 years. This allows queue IDs to be assigned
without fancy file system locking. Queued items can be
moved between queues easily. Contributed by Exactis.com,
Inc.
Messages which are undeliverable due to temporary address failures
(e.g., DNS failure) will now go to the FallBackMX host, if
set. Contributed by Exactis.com, Inc.
New command line option '-L tag' which sets the identifier used for
syslog. Contributed by Exactis.com, Inc.
QueueSortOrder=Filename will sort the queue by filename. This
avoids opening and reading each queue file when preparing
to run the queue. Contributed by Exactis.com, Inc.
Shared memory counters and microtimers functionality has been
donated by Exactis.com, Inc.
The SCCS ID tags have been replaced with RCS ID tags.
Allow trusted users (those on a T line or in $=t) to set the
QueueDirectory (Q) option without an X-Authentication-Warning:
being added. Suggested by Michael K. Sanders.
IPv6 support based on patches from John Kennedy of Cal State
University, Chico, Motonori Nakamura of Kyoto University,
and John Beck of Sun Microsystems.
In low-disk space situations, where sendmail would previously refuse
connections, still accept them, but only allow ETRN commands.
Suggested by Mathias Koerber of Singapore Telecommunications
Ltd.
The [IPC] builtin mailer now allows delivery to a UNIX domain socket
on systems which support them. This can be used with LMTP
local delivery agents which listen on a named socket. An
example mailer might be:
Mexecmail, P=[IPC], F=lsDFMmnqSXzA5@/:|, E=\r\n,
S=10, R=20/40, T=DNS/RFC822/X-Unix,
A=FILE /var/run/lmtpd
Code contributed by Lyndon Nerenberg of Messaging Direct.
The [TCP] builtin mailer name is now deprecated. Use [IPC]
instead.
The first mailer argument in the [IPC] mailer is now checked for a
legitimate value. Possible values are TCP (for TCP/IP
connections), IPC (which will be deprecated in a future
version), and FILE (for UNIX domain socket delivery).
PrivacyOptions=goaway no longer includes the noetrn and the noreceipts
flags.
PrivacyOptions=nobodyreturn instructs sendmail not to include the
body of the original message on delivery status
notifications.
Don't announce DSN if PrivacyOptions=noreceipts is set. Problem noted
by Dan Bernstein, fix from Robert Harker of Harker Systems.
Accept the SMTP RSET command even when rejecting commands due to TCP
Wrappers or the check_relay ruleset. Problem noted by
Steve Schweinhart of America Online.
Warn if OperatorChars is set multiple times. OperatorChars should
not be set after rulesets are defined. Suggested by
Mitchell Blank Jr of Exec-PC.
Do not report temporary failure on delivery to files. In
interactive delivery mode, this would result in two SMTP
responses after the DATA command. Problem noted by
Nik Conwell of Boston University.
Check file close when mailing to files. Problem noted by Nik
Conwell of Boston University.
Avoid a segmentation fault when using the LDAP map. Patch from
Curtis W. Hillegas of Princeton University.
Always bind to the LDAP server regardless of whether you are using
ldap_open() or ldap_init(). Fix from Raj Kunjithapadam of
@Home Network.
New ruleset trust_auth to determine whether a given AUTH=
parameter of the MAIL command should be trusted. See SMTP
AUTH, cf/README, and doc/op/op.ps.
Allow new named config file rules check_vrfy, check_expn, and
check_etrn for VRFY, EXPN, and ETRN commands, respectively,
similar to check_rcpt etc.
Introduce new macros ${rcpt_mailer}, ${rcpt_host}, ${rcpt_addr},
${mail_mailer}, ${mail_host}, ${mail_addr} that hold
the results of parsing the RCPT and MAIL arguments, i.e.
the resolved triplet from $#mailer $@host $:addr.
From Kari Hurtta of the Finnish Meteorological Institute.
New macro ${client_resolve} which holds the result of the resolve
call for ${client_name}: OK, FAIL, FORGED, TEMP. Proposed
by Kari Hurtta of the Finnish Meteorological Institute.
New macros ${dsn_notify}, ${dsn_envid}, and ${dsn_ret} that hold
the corresponding DSN parameter values. Proposed by
Mathias Herberts.
New macro ${msg_size} which holds the value of the SIZE= parameter,
i.e., usually the size of the message (in an ESMTP dialogue),
before the message has been collected, thereafter it holds
the message size as computed by sendmail (and can be used
in check_compat).
The macro ${deliveryMode} now specifies the current delivery mode
sendmail is using instead of the value of the DeliveryMode
option.
New macro ${ntries} holds the number of delivery attempts.
Drop explicit From: if same as what would be generated only if it is
a local address. From Motonori Nakamura of Kyoto University.
Write pid to file also if sendmail only processes the queue.
Proposed by Roy J. Mongiovi of Georgia Tech.
Log "low on disk space" only when necessary.
New macro ${load_avg} can be used to check the current load average.
Suggested by Scott Gifford of The Internet Ramp.
Return-Receipt-To: header implies DSN request if option RrtImpliesDsn
is set.
Flag -S for maps to specify the character which is substituted
for spaces (instead of the default given by O BlankSub).
Flag -D for maps: perform no lookup in deferred delivery mode.
This flag is set by default for the host map. Based on a
proposal from Ian MacPhedran of the University of Saskatchewan.
Open maps only on demand, not at startup.
Log warning about unsupported IP address families.
New option MaxHeadersLength allows to specify a maximum length
of the sum of all headers. This can be used to prevent
a denial-of-service attack.
New option MaxMimeHeaderLength which limits the size of MIME
headers and parameters within those headers. This option
is intended to protect mail user agents from buffer
overflow attacks.
Added option MaxAliasRecursion to specify the maximum depth of
alias recursion.
New flag F=6 for mailers to strip headers to seven bit.
Map type syslog to log the key via syslogd.
Entries in the alias file can be continued by putting a backslash
directly before the newline.
New option DeadLetterDrop to define the location of the system-wide
dead.letter file, formerly hardcoded to
/usr/tmp/dead.letter. If this option is not set (the
default), sendmail will not attempt to save to a
system-wide dead.letter file if it can not bounce the mail
to the user nor postmaster. Instead, it will rename the qf
file as it has in the past when the dead.letter file
could not be opened.
New option PidFile to define the location of the pid file. The
value of this option is macro expanded.
New option ProcessTitlePrefix specifies a prefix string for the
process title shown in 'ps' listings.
New macros for use with the PidFile and ProcessTitlePrefix options
(along with the already existing macros):
${daemon_info} Daemon information, e.g.
SMTP+queueing@00:30:00
${daemon_addr} Daemon address, e.g., 0.0.0.0
${daemon_family} Daemon family, e.g., inet, inet6, etc.
${daemon_name} Daemon name, e.g., MSA.
${daemon_port} Daemon port, e.g., 25
${queue_interval} Queue run interval, e.g., 00:30:00
New macros especially for virtual hosting:
${if_name} hostname of interface of incoming connection.
${if_addr} address of interface of incoming connection.
The latter is only set if the interface does not belong to the
loopback net.
If a message being accepted via a method other than SMTP and
would be rejected by a header check, do not send the message.
Suggested by Phil Homewood of Mincom Pty Ltd.
Don't strip comments for header checks if $>+ is used instead of $>.
Provide header value as quoted string in the macro
${currHeader} (possibly truncated to MAXNAME). Suggested by
Jan Krueger of Unix-AG of University of Hannover.
The length of the header value is stored in ${hdrlen}.
H*: allows to specify a default ruleset for header checks. This
ruleset will only be called if the individual header does
not have its own ruleset assigned. Suggested by Jan
Krueger of Unix-AG of University of Hannover.
The name of the header field stored in ${hdr_name}.
Comments (i.e., text within parentheses) in rulesets are not
removed if the config file version is greater than or equal
to 9. For example, "R$+ ( 1 ) $@ 1" matches the
input "token (1)" but does not match "token".
Avoid removing the Content-Transfer-Encoding MIME header on
MIME messages. Problem noted by Sigurbjorn B. Larusson of
Multimedia Consumer Services. Fix from Per Hedeland of
Ericsson.
Avoid duplicate Content-Transfer-Encoding MIME header on
messages with 8-bit text in headers. Problem noted by
Per Steinar Iversen of Oslo College. Fix from Per Hedeland
of Ericsson.
Avoid keeping maps locked longer than necessary when re-opening a
modified database map file. Problem noted by Chris Adams
of Renaissance Internet Services.
Resolving to the $#error mailer with a temporary failure code (e.g.,
$#error $@ tempfail $: "400 Temporary failure") will now
queue up the message instead of bouncing it.
Be more liberal in acceptable responses to an SMTP RSET command as
standard does not provide any indication of what to do when
something other than 250 is received. Based on a patch
from Steve Schweinhart of America Online.
New option TrustedUser allows to specify a user who can own
important files instead of root. This requires HASFCHOWN.
Fix USERDB conditional so compiling with NEWDB or HESIOD and
setting USERDB=0 works. Fix from Jorg Zanger of Schock.
Fix another instance (similar to one in 8.9.3) of a network failure
being mis-logged as "Illegal Seek" instead of whatever
really went wrong. From John Beck of Sun Microsystems.
$? tests also whether the macro is non-null.
Print an error message if a mailer definition contains an invalid
equate name.
New mailer equate /= to specify a directory to chroot() into before
executing the mailer program. Suggested by Igor Vinokurov.
New mailer equate W= to specify the maximum time to wait for the
mailer to return after sending all data to it.
Only free memory from the process list when adding a new process
into a previously filled slot. Previously, the memory was
freed at removal time. Since removal can happen in a
signal handler, this may leave the memory map in an
inconsistent state. Problem noted by Jeff A. Earickson and
David Cooley of Colby College.
When using the UserDB @hostname catch-all, do not try to lookup
local users in the passwd file. The UserDB code has
already decided the message will be passed to another host
for processing. Fix from Tony Landells of Burdett
Buckeridge Young Limited.
Support LDAP authorization via either a file containing the
password or Kerberos V4 using the new map options
'-ddistinguished_name', '-Mmethod', and '-Pfilename'. The
distinguished_name is who to login as. The method can be
one of LDAP_AUTH_NONE, LDAP_AUTH_SIMPLE, or
LDAP_AUTH_KRBV4. The filename is the file containing the
secret key for LDAP_AUTH_SIMPLE or the name of the Kerberos
ticket file for LDAP_AUTH_KRBV4. Patch from Booker Bense
of Stanford University.
The ldapx map has been renamed to ldap. The use of ldapx is
deprecated and will be removed in a future version.
If the result of an LDAP search returns a multi-valued attribute
and the map has the column delimiter set, it turns that
response into a delimiter separated string. The LDAP map
will traverse multiple entries as well. LDAP alias maps
automatically set the column delimiter to the comma.
Based on patch from Booker Bense of Stanford University and
idea from Philip A. Prindeville of Mirapoint, Inc.
Support return of multiple values for a single LDAP lookup. The
values to be returned should be in a comma separated string.
For example, `-v "email,emailother"'. Patch from
Curtis W. Hillegas of Princeton University.
Allow the use of LDAP for alias maps.
If no LDAP attributes are specified in an LDAP map declaration, all
attributes found in the match will be returned.
Prevent commas in quoted strings in the AliasFile value from
breaking up a single entry into multiple entries. This is
needed for LDAP alias file specifications to allow for
comma separated key and value strings.
Keep connections to LDAP server open instead of opening and closing
for each lookup. To reduce overhead, sendmail will cache
connections such that multiple maps which use the same
host, port, bind DN, and authentication will only result in
a single connection to that host.
Put timeout in the proper place for USE_LDAP_INIT.
Be more careful about checking for errors and freeing memory on
LDAP lookups.
Use asynchronous LDAP searches to save memory and network
resources.
Do not copy LDAP query results if the map's match only flag is set.
Increase portability to the Netscape LDAP libraries.
Change the parsing of the LDAP filter specification. '%s' is still
replaced with the literal contents of the map lookup key --
note that this means a lookup can be done using the LDAP
special characters. The new '%0' token can be used instead
of '%s' to encode the key buffer according to RFC 2254.
For example, if the LDAP map specification contains '-k
"(user=%s)"' and a lookup is done on "*", this would be
equivalent to '-k "(user=*)"' -- matching ANY record with a
user attribute. Instead, if the LDAP map specification
contains '-k "(user=%0)"' and a lookup is done on "*", this
would be equivalent to '-k "(user=\2A)"' -- matching a user
with the name "*".
New LDAP map flags: "-1" requires a single match to be returned, if
more than one is returned, it is equivalent to no records
being found; "-r never|always|search|find" sets the LDAP
alias dereference option; "-Z size" limits the number of
matches to return.
New option LDAPDefaultSpec allows a default map specification for
LDAP maps. The value should only contain LDAP specific
settings such as "-h host -p port -d bindDN", etc. The
settings will be used for all LDAP maps unless they are
specified in the individual map specification ('K'
command). This option should be set before any LDAP maps
are defined.
Prevent an NDBM alias file opening loop when the NDBM open
continually fails. Fix from Roy J. Mongiovi of Georgia
Tech.
Reduce memory utilization for smaller symbol table entries. In
particular, class entries get much smaller, which can be
important if you have large classes.
On network-related temporary failures, record the hostname which
gave error in the queued status message. Requested by
Ulrich Windl of the Universitat Regensburg.
Add new F=% mailer flag to allow for a store and forward
configuration. Mailers which have this flag will not attempt
delivery on initial receipt of a message or on queue runs
unless the queued message is selected using one of the
-qI/-qR/-qS queue run modifiers or an ETRN request. Code
provided by Philip Guenther of Gustavus Adolphus College.
New option ControlSocketName which, when set, creates a daemon
control socket. This socket allows an external program to
control and query status from the running sendmail daemon
via a named socket, similar to the ctlinnd interface to the
INN news server. Access to this interface is controlled by
the UNIX file permissions on the named socket on most UNIX
systems (see sendmail/README for more information). An
example control program is provided as contrib/smcontrol.pl.
Change the default values of QueueLA from 8 to (8 * numproc) and
RefuseLA from 12 to (12 * numproc) where numproc is the
number of processors online on the system (if that can be
determined). For single processor machines, this change
has no effect.
Don't return body of message to postmaster on "Too many hops" bounces.
Based on fix from Motonori Nakamura of Kyoto University.
Give more detailed DSN descriptions for some cases. Patch from
Motonori Nakamura of Kyoto University.
Logging of alias, forward file, and UserDB expansion now happens
at LogLevel 11 or higher instead of 10 or higher.
Logging of an envelope's complete delivery (the "done" message) now
happens at LogLevel 10 or higher instead of 11 or higher.
Logging of TCP/IP or UNIX standard input connections now happens at
LogLevel 10 or higher. Previously, only TCP/IP connections
were logged, and on at LogLevel 12 or higher. Setting
LogLevel to 10 will now assist users in tracking frequent
connection-based denial of service attacks.
Log basic information about authenticated connections at LogLevel
10 or higher.
Log SMTP Authentication mechanism and author when logging the sender
information (from= syslog line).
Log the DSN code for each recipient if one is available as a new
equate (dsn=).
Macro expand PostmasterCopy and DoubleBounceAddress options.
New "ph" map for performing ph queries in rulesets, see
sendmail/README for details. Contributed by Mark Roth
of the University of Illinois at Urbana-Champaign.
Detect temporary lookup failures in the host map if looking up a
bracketed IP address. Problem noted by Kari Hurtta of the
Finnish Meteorological Institute.
Do not report a Remote-MTA on local deliveries. Problem noted by
Kari Hurtta of the Finnish Meteorological Institute.
When a forward file points to an alias which runs a program, run
the program as the default user and the default group, not
the forward file user. This change also assures the
:include: directives in aliases are also processed using
the default user and group. Problem noted by Sergiu
Popovici of DNT Romania.
Prevent attempts to save a dead.letter file for a user with
no home directory (/no/such/directory). Problem noted by
Michael Brown of Finnigan FT/MS.
Include message delay and number of tries when logging that a
message has been completely delivered (LogLevel of 10 or
above). Suggested by Nick Hilliard of Ireland Online.
Log the sender of a message even if none of the recipients were
accepted. If some of the recipients were rejected, it is
helpful to know the sender of the message.
Check the root directory (/) when checking a path for safety.
Problem noted by John Beck of Sun Microsystems.
Prevent multiple responses to the DATA command if DeliveryMode is
interactive and delivering to an alias which resolves to
multiple files.
Macros in the helpfile are expanded if the helpfile version is 2 or
greater (see below); the help function doesn't print the
version of sendmail any longer, instead it is placed in
the helpfile ($v). Suggested by Chuck Foster of UUNET
PIPEX. Additionally, comment lines (starting with #) are
skipped and a version line (#vers) is introduced. The
helpfile version for 8.10.0 is 2, if no version or an older
version is found, a warning is logged. The '#vers'
directive should be placed at the top of the help file.
Use fsync() when delivering to a file to guarantee the delivery to
disk succeeded. Suggested by Nick Christenson.
If delivery to a file is unsuccessful, truncate the file back to its
length before the attempt.
If a forward points to a filename for delivery, change to the
user's uid before checking permissions on the file. This
allows delivery to files on NFS mounted directories where
root is remapped to nobody. Problem noted by Harald
Daeubler of Universitaet Ulm.
purgestat and sendmail -bH purge only expired (Timeout.hoststatus)
host status files, not all files.
Any macros stored in the class $={persistentMacros} will be saved
in the queue file for the message and set when delivery
is attempted on the queued item. Suggested by Kyle Jones of
Wonderworks Inc.
Add support for storing information between rulesets using the new
macro map class. This can be used to store information
between queue runs as well using $={persistentMacros}.
Based on an idea from Jan Krueger of Unix-AG of University
of Hannover.
New map class arith to allow for computations in rules. The
operation (+, -, *, /, l (for less than), and =) is given
as key. The two operands are specified as arguments; the
lookup returns the result of the computation. For example,
"$(arith l $@ 4 $@ 2 $)" will return "FALSE" and
"$(arith + $@ 4 $@ 2 $)" will return "6".
Add new syntax for header declarations which decide whether to
include the header based on a macro rather than a mailer
flag:
H?${MyMacro}?X-My-Header: ${MyMacro}
This should be used along with $={persistentMacros}.
It can be used for adding headers to a message based on
the results of check_* and header check rulesets.
Allow new named config file rule check_eoh which is called after
all of the headers have been collected. The input to the
ruleset the number of headers and the size of all of the
headers in bytes separated by $|. This ruleset along with
the macro storage map can be used to correlate information
gathered between headers and to check for missing headers.
See cf/README or doc/op/op.ps for an example.
Change the default for the MeToo option to True to correspond
to the clarification in the DRUMS SMTP Update spec. This
option is deprecated and will be removed from a future
version.
Change the sendmail binary default for SendMimeErrors to True.
Change the sendmail binary default for SuperSafe to True.
Display ruleset names in debug and address test mode output
if referencing a named ruleset.
New mailer equate m= which will limit the number of messages
delivered per connection on an SMTP or LMTP mailer.
Improve QueueSortOrder=Host by reversing the hostname before
using it to sort. Now all the same domains are really run
through the queue together. If they have the same MX host,
then they will have a much better opportunity to use the
connection cache if available. This should be a reasonable
performance improvement. Patch from Randall Winchester of
the University of Maryland.
If a message is rejected by a header check ruleset, log who would
have received the message if it had not been rejected.
New "now" value for Timeout.queuereturn to bounce entries from the
queue immediately. No delivery attempt is made.
Increase sleeping time exponentially after too many "bad" commands
up to 4 minutes delay (compare MAX{BAD,NOOP,HELO,VRFY,ETRN}-
COMMANDS).
New option ClientPortOptions similar to DaemonPortOptions
but for outgoing connections.
New suboptions for DaemonPortOptions: Name (a name used for
error messages and logging) and Modifiers, i.e.
a require authentication
b bind to interface through which mail has
been received
c perform hostname canonification
f require fully qualified hostname
h use name of interface for outgoing HELO
command
C don't perform hostname canonification
E disallow ETRN (see RFC 2476)
New suboption for ClientPortOptions: Modifiers, i.e.
h use name of interface for HELO command
The version number for queue files (qf) has been incremented to 4.
Log unacceptable HELO/EHLO domain name attempts if LogLevel is set
to 10 or higher. Suggested by Rick Troxel of the National
Institutes of Health.
If a mailer dies, print the status in decimal instead of octal
format. Suggested by Michael Shapiro of Sun Microsystems.
Limit the length of all MX records considered for delivery to 8k.
Move message priority from sender to recipient logging. Suggested by
Ulrich Windl of the Universitat Regensburg.
Add support for Berkeley DB 3.X.
Add fix for Berkeley DB 2.X fcntl() locking race condition.
Requires a post-2.7.5 version of Berkeley DB.
Support writing traffic log (sendmail -X option) to a FIFO.
Patch submitted by Rick Heaton of Network Associates, Inc.
Do not ignore Timeout settings in the .cf file when a Timeout
sub-options is set on the command line. Problem noted by
Graeme Hewson of Oracle.
Randomize equal preference MX records each time delivery is
attempted via a new connection to a host instead of once per
session. Suggested by Scott Salvidio of Compaq.
Implement enhanced status codes as defined by RFC 2034.
Add [hostname] to class w for the names of all interfaces unless
DontProbeInterfaces is set. This is useful for sending mails
to hosts which have dynamically assigned names.
If a message is bounced due to bad MIME conformance, avoid bouncing
the bounce for the same reason. If the body is not 8-bit
clean, and EightBitMode isn't set to pass8, the body will
not be included in the bounce. Problem noted by Valdis
Kletnieks of Virginia Tech.
The timeout for sending a message via SMTP has been changed from
'${msgsize} / 16 + (${nrcpts} * 300)' to a timeout which
simply checks for progress on sending data every 5 minutes.
This will detect the inability to send information quicker
and reduce the number of processes simply waiting to
timeout.
Prevent a segmentation fault on systems which give a partial filled
interface address structure when loading the system network
interface addresses. Fix from Reinier Bezuidenhout of
Nanoteq.
Add a compile-time configuration macro, MAXINTERFACES, which
indicates the number of interfaces to read when probing
for hostnames and IP addresses for class w ($=w). The
default value is 512. Based on idea from Reinier
Bezuidenhout of Nanoteq.
If the RefuseLA option is set to 0, do not reject connections based
on load average.
Allow ruleset 0 to have a name. Problem noted by Neil Rickert of
Northern Illinois University.
Expand the Return-Path: header at delivery time, after "owner-"
envelope splitting has occurred.
Don't try to sort the queue if there are no entries. Patch from
Luke Mewburn from RMIT University.
Add a "/quit" command to address test mode.
Include the proper sender in the UNIX "From " line and Return-Path:
header when undeliverable mail is saved to ~/dead.letter.
Problem noted by Kari Hurtta of the Finnish Meteorological
Institute.
The contents of a class can now be copied to another class using
the syntax: "C{Dest} $={Source}". This would copy all of
the items in class $={Source} into the class $={Dest}.
Include original envelope's error transcript in bounces created for
split (owner-) envelopes to see the original errors when
the recipients were added. Based on fix from Motonori
Nakamura of Kyoto University.
Show reason for permanent delivery errors directly after the
addresses. From Motonori Nakamura of Kyoto University.
Prevent a segmentation fault when bouncing a split-envelope
message. Patch from Motonori Nakamura of Kyoto University.
If the specification for the queue run interval (-q###) has a
syntax error, consider the error fatal and exit.
Pay attention to CheckpointInterval during LMTP delivery. Problem
noted by Motonori Nakamura of Kyoto University.
On operating systems which have setlogin(2), use it to set the
login name to the RunAsUserName when starting as a daemon.
This is for delivery to programs which use getlogin().
Based on fix from Motonori Nakamura of Kyoto University.
Differentiate between "command not implemented" and "command
unrecognized" in the SMTP dialogue.
Strip returns from forward and include files. Problem noted by
Allan E Johannesen of Worcester Polytechnic Institute.
Prevent a core dump when using 'sendmail -bv' on an address which
resolves to the $#error mailer with a temporary failure.
Based on fix from Neil Rickert of Northern Illinois
University.
Prevent multiple deliveries of a message with a "non-local alias"
pointing to a local user, if canonicalization fails
the message was requeued *and* delivered to the alias.
If an invalid ruleset is declared, the ruleset name could be
ignored and its rules added to S0. Instead, ignore the
ruleset lines as well.
Avoid incorrect Final-Recipient, Action, and X-Actual-Recipient
success DSN fields as well as duplicate entries for a
single address due to S5 and UserDB processing. Problems
noted by Kari Hurtta of the Finnish Meteorological
Institute.
Turn off timeouts when exiting sendmail due to an interrupt signal
to prevent the timeout from firing during the exit process.
Problem noted by Michael Shapiro of Sun Microsystems.
Do not append @MyHostName to non-RFC822 addresses output by the EXPN
command or on Final-Recipient: and X-Actual-Recipient: DSN
headers. Non-RFC822 addresses include deliveries to
programs, file, DECnet, etc.
Fix logic for determining if a local user is using -f or -bs to
spoof their return address. Based on idea from Neil Rickert
of Northern Illinois University and patch from Per Hedeland
of Ericsson.
Report the proper UID in the bounce message if an :include: file is
owned by a uid that doesn't map to a username and the
:include: file contains delivery to a file or program.
Problem noted by John Beck of Sun Microsystems.
Avoid the attempt of trying to send a second SMTP QUIT command if
the remote server responds to the first QUIT with a 4xx
response code and drops the connection. This behavior was
noted by Ulrich Windl of the Universitat Regensburg when
sendmail was talking to the Mercury 1.43 MTA.
If a hostname lookup times out and ServiceSwitchFile is set but the
file is not present, the lookup failure would be marked as
a permanent failure instead of a temporary failure. Fix
from Russell King of the ARM Linux Project.
Handle aliases or forwards which deliver to programs using tabs
instead of spaces between arguments. Problem noted by Randy
Wormser. Fix from Neil Rickert of Northern Illinois
University.
Allow MaxRecipientsPerMessage option to be set on the command line
by normal users (e.g., sendmail won't drop its root
privileges) to allow overrides for message submission via
'sendmail -bs'.
Set the names for help file and statistics file to "helpfile" and
"statistics", respectively, if no parameters are given for
them in the .cf file.
Avoid bogus 'errbody: I/O Error -7' log messages when sending
success DSN messages for messages relayed to non-DSN aware
systems. Problem noted by Juergen Georgi of RUS University
of Stuttgart and Kyle Tucker of Parexel International.
Prevent +detail information from interfering with local delivery to
multiple users in the same transaction (F=m).
Add H_FORCE flag for the X-Authentication-Warning: header, so it
will be added even if one already exists. Problem noted
by Michal Zalewski of Marchew Industries.
Stop processing SMTP commands if the SMTP connection is dropped.
This prevents a remote system from flooding the connection
with commands and then disconnecting. Previously, the
server would process all of the buffered commands. Problem
noted by Michal Zalewski of Marchew Industries.
Properly process user-supplied headers beginning with '?'. Problem
noted by Michal Zalewski of Marchew Industries.
If multiple header checks resolve to the $#error mailer, use the
last permanent (5XX) failure if any exist. Otherwise, use
the last temporary (4XX) failure.
RFC 1891 requires "hexchar" in a "xtext" to be upper case. Patch
from Ronald F. Guilmette of Infinite Monkeys & Co.
Timeout.ident now defaults to 5 seconds instead of 30 seconds to
prevent the now common delays associated with mailing to a
site which drops IDENT packets. Suggested by many.
Persistent host status data is not reloaded disk when current data
is available in the in-memory cache. Problem noted by Per
Hedeland of Ericsson.
mailq displays unprintable characters in addresses as their octal
representation and a leading backslash. This avoids problems
with "unprintable" characters. Problem noted by Michal
Zalewski of the "Internet for Schools" project (IdS).
The mail line length limit (L= equate) was adding the '!' indicator
one character past the limit. This would cause subsequent
hops to break the line again. The '!' is now placed in
the last column of the limit if the line needs to be broken.
Problem noted by Joe Pruett of Q7 Enterprises. Based on fix
from Per Hedeland of Ericsson.
If a resolver ANY query is larger than the UDP packet size, the
resolver will fall back to TCP. However, some
misconfigured firewalls block 53/TCP so the ANY lookup
fails whereas an MX or A record might succeed. Therefore,
don't fail on ANY queries.
If an SMTP recipient is rejected due to syntax errors in the
address, do not send an empty postmaster notification DSN
to the postmaster. Problem noted by Neil Rickert of
Northern Illinois University.
Allow '_' and '.' in map names when parsing a sequence map
specification. Patch from William Setzer of North Carolina
State University.
Fix hostname in logging of read timeouts for the QUIT command on
cached connections. Problem noted by Neil Rickert of
Northern Illinois University.
Use a more descriptive entry to log "null" connections, i.e.,
"host did not issue MAIL/EXPN/VRFY/ETRN during connection".
Fix a file descriptor leak in ONEX mode.
Portability:
Reverse signal handling logic such that sigaction(2) with
the SA_RESTART flag is the preferred method and the
other signal methods are only tried if SA_RESTART
is not available. Problem noted by Allan E
Johannesen of Worcester Polytechnic Institute.
AIX 4.x supports the sa_len member of struct sockaddr.
This allows network interface probing to work
properly. Fix from David Bronder of the
University of Iowa.
AIX 4.3 has snprintf() support.
Use "PPC" as the architecture name when building under
AIX. This will be reflected in the obj.* directory
name.
Apple Darwin support based on Apple Rhapsody port.

_PATH_SENDMAILPID from Oota Toshiya of
NEC Computers Group Planning Division.
Minor NetBSD owner/group tweaks from Ayamura Kikuchi, M.D.
NEWS-OS 6.X listed SYSLOG_BUFSIZE as 256 in confENVDEF and
1024 in conf.h. Since confENVDEF would be used,
use that value in conf.h.
Use NeXT's NETINFO to get domain name. From Gerd Knops of
BITart Consulting.
Use NeXT's NETINFO for alias and hostname resolution if
AUTO_NETINFO_ALIASES and AUTO_NETINFO_HOSTS are
defined. Patch from Wilfredo Sanchez of Apple
Computer, Inc.
NeXT portability tweaks. Problems reported by Dragan
Milicic of the University of Utah and J. P. McCann
of E I A.
New compile flag FAST_PID_RECYCLE: set this if your system
can reuse the same PID in the same second.
New compile flag HASFCHOWN: set this if your OS has
fchown(2).
New compile flag HASRANDOM: set this to 0 if your OS does
not have random(3). rand() will be used instead.
New compile flag HASSRANDOMDEV: set this if your OS has
srandomdev(3).
New compile flag HASSETLOGIN: set this if your OS has
setlogin(2).
Replace SINIX and ReliantUNIX support with version
specific SINIX files. From Gerald Rinske of
Siemens Business Services.
Use the 60-second load average instead of the 5 second load
average on Compaq Tru64 UNIX (formerly Digital
UNIX). From Chris Teakle of the University of Qld.
Use ANSI C by default for Compaq Tru64 UNIX. Suggested by
Randall Winchester of Swales Aerospace.
Correct setgroups() prototype for Compaq Tru64 UNIX.
Problem noted by Randall Winchester of Swales
Aerospace.
Hitachi 3050R/3050RX and 3500 Workstations running
HI-UX/WE2 4.02, 6.10 and 7.10 from Motonori
NAKAMURA of Kyoto University.
New compile flag NO_GETSERVBYNAME: set this to disable
use of getservbyname() on systems which can
not lookup a service by name over NIS, such as
HI-UX. Patch from Motonori NAKAMURA of Kyoto
University.
Use devtools/bin/install.sh on SCO 5.x. Problem noted
by Sun Wenbing of the China Engineering and
Technology Information Network.
make depend didn't work properly on UNIXWARE 4.2. Problem
noted by Ariel Malik of Netology, Ltd.
Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
Set confSTDIO_TYPE to torek for BSD-OS, FreeBSD, NetBSD,
and OpenBSD.
A recent Compaq Ultrix 4.5 Y2K patch has broken detection
of local_hostname_length(). See sendmail/README
for more details. Problem noted by Allan E
Johannesen of Worcester Polytechnic Institute.
CONFIG: Begin using /etc/mail/ for sendmail related files. This
affects a large number of files. See cf/README for more
details.
CONFIG: New macro MAIL_SETTINGS_DIR contains the path (including
trailing slash) for the mail settings directory.
CONFIG: Increment version number of config file to 9.
CONFIG: OSTYPE(`bsdi1.0') and OSTYPE(`bsdi2.0') have been
deprecated and may be removed from a future release.
BSD/OS users should begin using OSTYPE(`bsdi').
CONFIG: OpenBSD 2.4 installs mail.local non-set-user-ID root. This
requires a new OSTYPE(`openbsd'). From Todd C. Miller of
Courtesan Consulting.
CONFIG: New OSTYPE(`hpux11') for HP/UX 11.X.
CONFIG: A syntax error in check_mail would cause fake top-level
domains (.BITNET, .DECNET, .FAX, .USENET, and .UUCP) to
be improperly rejected as unresolvable.
CONFIG: New FEATURE(`dnsbl') takes up to two arguments (name of
DNS server, rejection message) and can be included
multiple times.
CONFIG: New FEATURE(`relay_mail_from') allows relaying if the
mail sender is listed as RELAY in the access map (and tagged
with From:).
CONFIG: Optional tagging of LHS in the access map (Connect:,
From:, To:) to enable finer control.
CONFIG: New FEATURE(`ldap_routing') implements LDAP address
routing. See cf/README for a complete description of the
new functionality.
CONFIG: New variables for the new sendmail options:
confAUTH_MECHANISMS AuthMechanisms

CONFIG: confDAEMON_OPTIONS has been replaced by DAEMON_OPTIONS(),
which takes the options as argument and can be used
multiple times; see cf/README for details.
CONFIG: Add a fifth mailer definition to MAILER(`smtp') called
"dsmtp". This mail provides on-demand delivery using the
F=% mailer flag described above. The "dsmtp" mailer
definition uses the new DSMTP_MAILER_ARGS which defaults
to "IPC $h".
CONFIG: New variables LOCAL_MAILER_MAXMSGS, SMTP_MAILER_MAXMSGS,
and RELAY_MAILER_MAXMSGS for setting the m= equate for the
local, smtp, and relay mailers respectively.
CONFIG: New variable LOCAL_MAILER_DSN_DIAGNOSTIC_CODE for setting
the DSN Diagnostic-Code type for the local mailer. The
value should be changed with care.
CONFIG: FEATURE(`local_lmtp') now sets the DSN Diagnostic-Code type
for the local mailer to the proper value of "SMTP".
CONFIG: All included maps are no longer optional by default; if
there there is a problem with a map, sendmail will
complain.
CONFIG: Removed root from class E; use EXPOSED_USER(`root')
to get the old behavior. Suggested by Joe Pruett
of Q7 Enterprises.
CONFIG: MASQUERADE_EXCEPTION() defines hosts/subdomains which
will not be masqueraded. Proposed by Arne Wichmann
of MPI Saarbruecken, Griff Miller of PGS Tensor,
Jayme Cox of Broderbund Software Inc.
CONFIG: A list of exceptions for FEATURE(`nocanonify') can be
specified by CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE,
i.e., a list of domains which are passed to $[ ... $]
for canonification. Based on an idea from Neil Rickert
of Northern Illinois University.
CONFIG: If `canonify_hosts' is specified as parameter for
FEATURE(`nocanonify') then addresses which have only
a hostname, e.g., <user@host>, will be canonified.
CONFIG: If FEATURE(`nocanonify') is turned on, a trailing dot is
nevertheless added to addresses with more than one component
in it.
CONFIG: Canonification is no longer attempted for any host or domain
in class 'P' ($=P).
CONFIG: New class for matching virtusertable entries $={VirtHost} that
can be populated by VIRTUSER_DOMAIN or VIRTUSER_DOMAIN_FILE.
FEATURE(`virtuser_entire_domain') can be used to apply this
class also to entire subdomains. Hosts in this class are
treated as canonical in SCanonify2, i.e., a trailing dot
is added.
CONFIG: If VIRTUSER_DOMAIN() or VIRTUSER_DOMAIN_FILE() are used,
include $={VirtHost} in $=R (hosts allowed to relay).
CONFIG: FEATURE(`generics_entire_domain') can be used to apply the
genericstable also to subdomains of $=G.
CONFIG: Pass "+detail" as %2 for virtusertable lookups.
Patch from Noam Freedman from University of Chicago.
CONFIG: Pass "+detail" as %1 for genericstable lookups. Suggested
by Raymond S Brand of rsbx.net.
CONFIG: Allow @domain in genericstable to override masquerading.
Suggested by Owen Duffy from Owen Duffy & Associates.
CONFIG: LOCAL_DOMAIN() adds entries to class w. Suggested by Steve
Hubert of University of Washington.
CONFIG: OSTYPE(`gnuhurd') has been replaced by OSTYPE(`gnu') as
GNU is now the canonical system name. From Mark
Kettenis of the University of Amsterdam.
CONFIG: OSTYPE(`unixware7') updates from Larry Rosenman.
CONFIG: Do not include '=' in option expansion if there is no value
associated with the option. From Andrew Brown of
Graffiti World Wide, Inc.
CONFIG: Add MAILER(`qpage') to define a new pager mailer. Contributed
by Philip A. Prindeville of Enteka Enterprise Technology
Services.
CONFIG: MAILER(`cyrus') was not preserving case for mail folder
names. Problem noted by Randall Winchester of Swales
Aerospace.
CONFIG: RELAY_MAILER_FLAGS can be used to define additional flags
for the relay mailer. Suggested by Doug Hughes of Auburn
University and Brian Candler.
CONFIG: LOCAL_MAILER_FLAGS now includes 'P' (Add Return-Path:
header) by default. Suggested by Per Hedeland of Ericsson.
CONFIG: Use SMART_HOST for bracketed addresses, e.g., user@[host].
Suggested by Kari Hurtta of the Finnish Meteorological
Institute.
CONFIG: New macro MODIFY_MAILER_FLAGS to tweak *_MAILER_FLAGS;
i.e., to set, add, or delete flags.
CONFIG: If SMTP AUTH is used then relaying is allowed for any user
who authenticated via a "trusted" mechanism, i.e., one that
is defined via TRUST_AUTH_MECH(`list of mechanisms').
CONFIG: FEATURE(`delay_checks') delays check_mail and check_relay
after check_rcpt and allows for exceptions from the checks.
CONFIG: Map declarations have been moved into their associated
feature files to allow greater flexibility in use of
sequence maps. Suggested by Per Hedeland of Ericsson.
CONFIG: New macro LOCAL_MAILER_EOL to override the default end of
line string for the local mailer. Requested by Il Oh of
Willamette Industries, Inc.
CONFIG: Route addresses are stripped, i.e., <@a,@b,@c:user@d> is
converted to <user@d>
CONFIG: Reject bogus return address of <@@hostname>, generated by
Sun's older, broken configuration files.
CONFIG: FEATURE(`nullclient') now provides the full rulesets of a
normal configuration, allowing anti-spam checks to be
performed.
CONFIG: Don't return a permanent error (Relaying denied) if
${client_name} can't be resolved just temporarily.
Suggested by Kari Hurtta of the Finnish Meteorological
Institute.
CONFIG: Change numbered rulesets into named (which still can
be accessed by their numbers).
CONFIG: FEATURE(`nouucp') takes one parameter: reject or nospecial
which describes whether to disallow "!" in the local part
of an address.
CONFIG: Call Local_localaddr from localaddr (S5) which can be used
to rewrite an address from a mailer which has the F=5 flag
set. If the ruleset returns a mailer, the appropriate
action is taken, otherwise the returned tokens are ignored.
CONFIG: cf/ostype/solaris.m4 has been renamed to solaris2.pre5.m4
and cf/ostype/solaris2.m4 is now a copy of solaris2.ml.m4.
The latter is kept around for backward compatibility.
CONFIG: Allow ":D.S.N:" for mailer/virtusertable "error:" entries,
where "D.S.N" is an RFC 1893 compliant error code.
CONFIG: Use /usr/lbin as confEBINDIR for Compaq Tru64 (Digital UNIX).
CONFIG: Remove second space between username and date in UNIX From_
line. Noted by Allan E Johannesen of Worcester Polytechnic
Institute.
CONFIG: Make sure all of the mailers have complete T= equates.
CONFIG: Extend FEATURE(`local_procmail') so it can now take
arguments overriding the mailer program, arguments, and
mailer definition flags. This makes it possible to use
other programs such as maildrop for local delivery.
CONFIG: Emit warning if FEATURE(`local_lmtp') or
FEATURE(`local_procmail') is given after MAILER(`local').
Patch from Richard A. Nelson of IBM.
CONFIG: Add SMTP Authentication information to Received: header
default value (confRECEIVED_HEADER).
CONFIG: Remove `l' flag from USENET_MAILER_FLAGS as it is not a
local mailer. Problem noted by Per Hedeland of Ericsson.
CONTRIB: Added bounce-resender.pl from Brian R. Gaeke of the
University of California at Berkeley.
CONTRIB: Added domainmap.m4 from Mark D. Roth of the University of
Illinois at Urbana-Champaign.
CONTRIB: etrn.pl now recognizes bogus host names. Patch from
Bruce Barnett of GE's R&D Lab.
CONTRIB: Patches for re-mqueue.pl by Graeme Hewson of Oracle
Corporation UK.
CONTRIB: Added qtool.pl to assist in managing the queues.
DEVTOOLS: Prevent user environment variables from interfering with
the Build scripts. Problem noted by Ezequiel H. Panepucci of
Yale University.
DEVTOOLS: 'Build -M' will display the obj.* directory which will
be used for building.
DEVTOOLS: 'Build -A' will display the architecture that would be
used for a fresh build.
DEVTOOLS: New variable confRANLIB, set automatically by configure.sh.
DEVTOOLS: New variable confRANLIBOPTS for the options to send to
ranlib.
DEVTOOLS: 'Build -O <path>' will have the object files build in
<path>/obj.*. Suggested by Bryan Costales of Exactis.
DEVTOOLS: New variable confNO_MAN_BUILD which will prevent the
building of the man pages when defined. Suggested by Bryan
Costales.
DEVTOOLS: New variables confNO_HELPFILE_INSTALL and
confNO_STATISTICS_INSTALL which will prevent the
installation of the sendmail helpfile and statistics file
respectively. Suggested by Bryan Costales.
DEVTOOLS: Recognize ReliantUNIX as SINIX. Patch from Gerald Rinske
of Siemens Business Services.
DEVTOOLS: New variable confSTDIO_TYPE which defines the type of
stdio library. The new buffered file I/O depends on the
Torek stdio library. This option can be either portable or
torek.
DEVTOOLS: New variables confSRCADD and confSMSRCADD which
correspond to confOBJADD and confSMOBJADD respectively.
They should contain the C source files for the object files
listed in confOBJADD and confSMOBJADD. These file names
will be passed to the 'make depend' stage of compilation.
DEVTOOLS: New program specific variables for each of the programs
in the sendmail distribution. Each has the form
`conf_prog_ENVDEF', for example, `conf_sendmail_ENVDEF'.
The new variables are conf_prog_ENVDEF, conf_prog_LIBS,
conf_prog_SRCADD, and conf_prog_OBJADD.
DEVTOOLS: Build system redesign. This should have little affect on
building the distribution, but documentation on the changes
are in devtools/README.
DEVTOOLS: Don't allow 'Build -f file' if an object directory already
exists. Suggested by Valdis Kletnieks of Virginia Tech.
DEVTOOLS: Rename confSRCDIR to confSMSRCDIR since it only identifies
the path to the sendmail source directory. confSRCDIR is a
new variable which identifies the root of the source
directories for all of the programs in the distribution.
DEVTOOLS: confSRCDIR and confSMSRCDIR are now determined at Build
time. They can both still be overridden by setting the m4
macro.
DEVTOOLS: confSBINGRP now defaults to bin instead of kmem.
DEVTOOLS: 'Build -Q prefix' uses devtools/Site/prefix.*.m4 for
build configurations, and places objects in obj.prefix.*/.
Complains as 'Build -f file' does for existing object
directories. Suggested by Tom Smith of Digital Equipment
Corporation.
DEVTOOLS: Setting confINSTALL_RAWMAN will install unformatted
manual pages in the directory tree specified by
confMANROOTMAN.
DEVTOOLS: If formatting the manual pages fails, copy in the
preformatted pages from the distribution. The new variable
confCOPY specifies the copying program.
DEVTOOLS: Defining confFORCE_RMAIL will install rmail without
question. Suggested by Terry Lambert of Whistle
Communications.
DEVTOOLS: confSTFILE and confHFFILE can be used to change the names
of the installed statistics and help files, respectively.
DEVTOOLS: Remove spaces in `uname -r` output when determining
operating system identity. Problem noted by Erik
Wachtenheim of Dartmouth College.
DEVTOOLS: New variable confLIBSEARCHPATH to specify the paths that
will be search for the libraries specified in confLIBSEARCH.
Defaults to "/lib /usr/lib /usr/shlib".
DEVTOOLS: New variables confSTRIP and confSTRIPOPTS for specifying
how to strip binaries. These are used by the new
install-strip target.
DEVTOOLS: New config file site.post.m4 which is included after
the others (if it exists).
DEVTOOLS: Change order of LIBS: first product specific libraries
then the default ones.
MAIL.LOCAL: Will not be installed set-user-ID root. To use mail.local
as local delivery agent without LMTP mode, use
MODIFY_MAILER_FLAGS(`LOCAL', `+S')
to set the S flag.
MAIL.LOCAL: Do not reject addresses which would otherwise be
accepted by sendmail. Suggested by Neil Rickert of
Northern Illinois University.
MAIL.LOCAL: New -7 option which causes LMTP mode not to advertise
8BITMIME in the LHLO response. Suggested by Kari Hurtta of
the Finnish Meteorological Institute.
MAIL.LOCAL: Add support for the maillock() routines by defining
MAILLOCK when compiling. Also requires linking with
-lmail. Patch from Neil Rickert of Northern Illinois
University.
MAIL.LOCAL: Create a Content-Length: header if CONTENTLENGTH is
defined when compiling. Automatically set for Solaris 2.3
and later. Patch from Neil Rickert of Northern Illinois
University.
MAIL.LOCAL: Move the initialization of the 'notifybiff' address
structure to the beginning of the program. This ensures that
the getservbyname() is done before any seteuid to a possibly
unauthenticated user. If you are using NIS+ and secure RPC
on a Solaris system, this avoids syslog messages such as,
"authdes_refresh: keyserv(1m) is unable to encrypt session
key." Patch from Neil Rickert of Northern Illinois
University.
MAIL.LOCAL: Support group writable mail spool files when MAILGID is
set to the gid to use (-DMAILGID=6) when compiling.
Patch from Neil Rickert of Northern Illinois University.
MAIL.LOCAL: When a mail message included lines longer than 2046
characters (in LMTP mode), mail.local split the incoming
line up into 2046-character output lines (excluding the
newline). If an input line was 2047 characters long
(excluding CR-LF) and the last character was a '.',
mail.local saw it as the end of input, transferred it to the
user mailbox and tried to write an `ok' back to sendmail.
If the message was much longer, both sendmail and
mail.local would deadlock waiting for each other to read
what they have written. Problem noted by Peter Jeremy of
Alcatel Australia Limited.
MAIL.LOCAL: New option -b to return a permanent error instead of a
temporary error if a mailbox exceeds quota. Suggested by
Neil Rickert of Northern Illinois University.
MAIL.LOCAL: The creation of a lockfile is subject to a global
timeout to avoid starvation.
MAIL.LOCAL: Properly parse addresses with multiple quoted
local-parts. Problem noted by Ronald F. Guilmette of
Infinite Monkeys & Co.
MAIL.LOCAL: NCR MP/RAS 3.X portability from Tom J. Moore of NCR.
MAILSTATS: New -p option to invoke program mode in which stats are
printed in a machine readable fashion and the stats file
is reset. Patch from Kevin Hildebrand of the University
of Maryland.
MAKEMAP: If running as root, automatically change the ownership of
generated maps to the TrustedUser as specified in the
sendmail configuration file.
MAKEMAP: New -C option to accept an alternate sendmail
configuration file to use for finding the TrustedUser
option.
MAKEMAP: New -u option to dump (unmap) a database. Based on
code contributed by Roy Mongiovi of Georgia Tech.
MAKEMAP: New -e option to allow empty values. Suggested by Philip
A. Prindeville of Enteka Enterprise Technology Services.
MAKEMAP: Compile cleanly on 64-bit operating systems. Problem
noted by Gerald Rinske of Siemens Business Services.
OP.ME: Correctly document interaction between F=S and U= mailer
equates. Problem noted by Bob Halley of Internet Engines.
OP.ME: Fixup Timeout documentation. From Graeme Hewson of Oracle
Corporation UK.
OP.ME: The Timeout [r] option was incorrectly listed as "safe"
(e.g., sendmail would not drop root privileges if the
option was specified on the command line). Problem noted
by Todd C. Miller of Courtesan Consulting.
PRALIASES: Handle the hash and btree map specifications for
Berkeley DB. Patch from Brian J. Coan of the
Institute for Global Communications.
PRALIASES: Read the sendmail.cf file for the location(s) of the
alias file(s) if the -f option is not used. Patch from
John Beck of Sun Microsystems.
PRALIASES: New -C option to specify an alternate sendmail
configuration file to use for finding alias file(s). Patch
from John Beck of Sun Microsystems.
SMRSH: allow shell commands echo, exec, and exit. Allow command
lists using || and &&. Based on patch from Brian J. Coan
of the Institute for Global Communications.
SMRSH: Update README for the new Build system. From Tim Pierce
of RootsWeb Genealogical Data Cooperative.
VACATION: Added vacation auto-responder to sendmail distribution.
LIBSMDB: Added abstracted database library. Works with Berkeley
DB 1.85, Berkeley DB 2.X, Berkeley DB 3.X, and NDBM.
Changed Files:
The Build script in the various program subdirectories are
no longer symbolic links. They are now scripts
which execute the actual Build script in
devtools/bin.
All the manual pages are now written against -man and not
-mandoc as they were previously.
Add a simple Makefile to every directory so make instead
of Build will work (unless parameters are
required for Build).

SECURITY: Limit message headers to a maximum of 32K bytes (total
of all headers in a single message) to prevent a denial of
service attack. This limit will be configurable in 8.10.
Problem noted by Michal Zalewski of the "Internet for
Schools" project (IdS).
Prevent segmentation fault on an LDAP lookup if the LDAP map
was closed due to an earlier failure. Problem noted by
Jeff Wasilko of smoe.org. Fix from Booker Bense of
Stanford University and Per Hedeland of Ericsson.
Preserve the order of the MIME headers in multipart messages
when performing the MIME header length check. This
will allow PGP signatures to function properly. Problem
noted by Lars Hecking of University College, Cork, Ireland.
If ruleset 5 rewrote the local address to an :include: directive,
the delivery would fail with an "aliasing/forwarding loop
broken" error. Problem noted by Eric C Hagberg of Morgan
Stanley. Fix from Per Hedeland of Ericsson.
Allow -T to work for bestmx maps. Fix from Aaron Schrab of
ExecPC Internet Systems.
During the transfer of a message in an SMTP transaction, if a
TCP timeout occurs, the message would be properly queued
for later retry but the failure would be logged as
"Illegal Seek" instead of a timeout. Problem noted by
Piotr Kucharski of the Warsaw School of Economics (SGH)
and Carles Xavier Munyoz Baldo of CTV Internet.
Prevent multiple deliveries on a self-referencing alias if the
F=w mailer flag is not set. Problem noted by Murray S.
Kucherawy of Concentric Network Corporation and Per
Hedeland of Ericsson.
Do not strip empty headers but if there is no value and a
default is defined in sendmail.cf, use the default.
Problem noted by Philip Guenther of Gustavus Adolphus
College and Christopher McCrory of Netus, Inc.
Don't inherit information about the sender (notably the full name)
in SMTP (-bs) mode, since this might be called from inetd.
Accept any 3xx reply code in response to DATA command instead of
requiring 354. This change will match the wording to be
published in the updated SMTP specification from the DRUMS
group of the IETF.
Portability:
AIX 4.2.0 or 4.2.1 may become updated by the fileset
bos.rte.net level 4.2.0.2. This introduces the
softlink /usr/lib/libbind.a which should
not be used. It conflicts with the resolver
built into libc.a. "bind" has been removed
from the confLIBSEARCH BuildTools variable.
Users who have installed BIND 8.X will have
to add it back in their site.config.m4 file.
Problem noted by Ole Holm Nielsen of the
Technical University of Denmark.
CRAY TS 10.0.x from Sven Nielsen of San Diego
Supercomputer Center.
Improved LDAP version 3 integration based on input
from Kurt D. Zeilenga of the OpenLDAP Foundation,
John Beck of Sun Microsystems, and Booker Bense
of Stanford University.
Linux doesn't have a standard way to get the timezone
between different releases. Back out the
change in 8.9.2 and don't attempt to derive
a timezone. Problem reported by Igor S. Livshits
of the University of Illinois at Urbana-Champaign
and Michael Dickens of Tetranet Communications.
Reliant UNIX, the new name for SINIX, from Gert-Jan Looy
of Siemens/SNI.
SunOS 5.8 from John Beck of Sun Microsystems.
CONFIG: SCO UnixWare 2.1 and 7.0 need TZ to get the proper

SECURITY: Remove five second sleep on accepting daemon connections
due to an accept() failure. This sleep could be used
for a denial of service attack.
Do not silently ignore queue files with names which are too long.
Patch from Bryan Costales of InfoBeat, Inc.
Do not store failures closing an SMTP session in persistent
host status. Reported by Graeme Hewson of Oracle
Corporation UK.
Allow symbolic link forward files if they are in safe directories.
Problem noted by Andreas Schott of the Max Planck Society.
Missing columns in a text map could cause a segmentation fault.
Fix from David Lee of the University of Durham.
Note that for 8.9.X, PrivacyOptions=goaway also includes the
noetrn flag. This is scheduled to change in a future
version of sendmail. Problem noted by Theo Van Dinter of
Chrysalis Symbolic Designa and Alan Brown of Manawatu
Internet Services.
When trying to do host canonification in a Wildcard MX
environment, try an MX lookup of the hostname without the
default domain appended. Problem noted by Olaf Seibert of
Polderland Language & Speech Technology.

'RCPT TO: (comment)'. Problem noted by Earle Ake of
Hassler Communication Systems Technology, Inc.
Handle any number of %s in the LDAP filter spec. Patch from
Per Hedeland of Ericsson.
Clear ldapx open timeouts even if the map open failed to prevent
a segmentation fault. Patch from Wayne Knowles of the
National Institute of Water & Atmospheric Research Ltd.
Do not syslog envelope clone messages when using address
verification (-bv). Problem noted by Kari Hurtta of the
Finnish Meteorological Institute.
Continue to perform queue runs while in daemon mode even if the
daemon is rejecting connections due to a disk full
condition. Problem noted by JR Oldroyd of TerraNet
Internet Services.
Include full filename on installation of the sendmail.hf file
in case the $HFDIR directory does not exist. Problem
noted by Josef Svitak of Montana State University.
Close all maps when exiting the process with one exception.
Berkeley DB can use internal shared memory locking for
its memory pool. Closing a map opened by another process
will interfere with the shared memory and locks of the
parent process leaving things in a bad state. For
Berkeley DB, only close the map if the current process
is also the one that opened the map, otherwise only close
the map file descriptor. Thanks to Yoseff Francus of
Collective Technologies for volunteering his system for
extended testing.
Avoid null pointer dereference on XDEBUG output for SMTP reply
failures. Problem noted by Carlos Canau of EUnet Portugal.
On mailq and hoststat listings being piped to another program, such
as more, if the pipe closes (i.e., the user quits more),
stop sending output and exit. Patch from Allan E Johannesen
of Worcester Polytechnic Institute.
In accordance with the documentation, LDAP map lookup failures
are now considered temporary failures instead of permanent
failures unless the -t flag is used in the map definition.
Problem noted by Booker Bense of Stanford University and
Eric C. Hagberg of Morgan Stanley.
Fix by one error reporting on long alias names. Problem noted by
H. Paul Hammann of the Missouri Research and Education
Network.
Fix DontBlameSendmail=IncludeFileInUnsafeDirPath behavior. Problem
noted by Barry S. Finkel of Argonne National Laboratory.
When automatically converting from 8 bit to quoted printable MIME,
be careful not to miss a multi-part boundary if that
boundary is preceded by a boundary-like line. Problem
noted by Andreas Raschle of Ansid Inc. Fix from
Kari Hurtta of the Finnish Meteorological Institute.
Avoid bogus reporting of "LMTP tobuf overflow" when the buffer
has enough space for the additional address. Problem
noted by Steve Cliffe of the University of Wollongong.
Fix DontBlameSendmail=FileDeliveryToSymlink behavior. Problem
noted by Alex Vorobiev of Swarthmore College.
If the check_compat ruleset resolves to the $#discard mailer,

New Files:
BuildTools/OS/DomainOS.10.4
8.9.0/8.9.0 1998/05/19
SECURITY: To prevent users from reading files not normally
readable, sendmail will no longer open forward, :include:,
class, ErrorHeader, or HelpFile files located in unsafe
(i.e., group or world writable) directory paths. Sites
which need the ability to override security can use the
DontBlameSendmail option. See the README file for more
information.
SECURITY: Problems can occur on poorly managed systems, specifically,
if maps or alias files are in world writable directories.
This fixes the change added to 8.8.6 to prevent links in these
world writable directories.
SECURITY: Make sure ServiceSwitchFile option file is not a link if
it is in a world writable directory.
SECURITY: Never pass a tty to a mailer -- if a mailer can get at the
tty it may be able to push bytes back to the senders input.
Unfortunately this breaks -v mode. Problem noted by
Wietse Venema of the Global Security Analysis Lab at
IBM T.J. Watson Research.
SECURITY: Empty group list if DontInitGroups is set to true to
prevent program deliveries from picking up extra group
privileges. Problem reported by Wolfgang Ley of DFN-CERT.
SECURITY: The default value for DefaultUser is now set to the uid and
gid of the first existing user mailnull, sendmail, or daemon
that has a non-zero uid. If none of these exist, sendmail
reverts back to the old behavior of using uid 1 and gid 1.
This is a security problem for Linux which has chosen that
uid and gid for user bin instead of daemon. If DefaultUser
is set in the configuration file, that value overrides this
default.
SECURITY: Since 8.8.7, the check for non-set-user-ID binaries
interfered with setting an alternate group id for the
RunAsUser option. Problem noted by Randall Winchester of
the University of Maryland.
Add support for Berkeley DB 2.X. Based on patch from John Kennedy
of Cal State University, Chico.
Remove support for OLD_NEWDB (pre-1.5 version of Berkeley DB). Users
which previously defined OLD_NEWDB=1 must now upgrade to the
current version of Berkeley DB.
Added support for regular expressions using the new map class regex.
From Jan Krueger of Unix-AG of University of Hannover.
Support for BIND 8.1.1's hesiod for hesiod maps and hesiod
UserDatabases from Randall Winchester of the University
of Maryland.
Allow any shell for user shell on program deliveries on V1
configurations for backwards compatibility on machines which
do not have getusershell(). Fix from John Beck of Sun
Microsystems.
On operating systems which change the process title by reusing the
argument vector memory, sendmail could corrupt memory if the
last argument was either "-q" or "-d". Problem noted by
Frank Langbein of the University of Stuttgart.
Support Local Mail Transfer Protocol (LMTP) between sendmail and
mail.local on the F=z flag.
Macro-expand the contents of the ErrMsgFile. Previously this was
only done if you had magic characters (0x81) to indicate
macro expansion. Now $x will be expanded. This means that
real dollar signs have to be backslash escaped.
TCP Wrappers expects "unknown" in the hostname argument if the
reverse DNS lookup for the incoming connection fails.
Problem noted by Randy Grimshaw of Syracuse University and
Wietse Venema of the Global Security Analysis Lab at
IBM T.J. Watson Research.
DSN success bounces generated from an invocation of sendmail -t
would be sent to both the sender and MAILER-DAEMON.
Problem noted by Claus Assmann of
Christian-Albrechts-University of Kiel.
Avoid "Error 0" messages on delivery mailers which exit with a
valid exit value such as EX_NOPERM. Fix from Andreas Luik
of ISA Informationssysteme GmbH.
Tokenize $&x expansions on right hand side of rules. This eliminates
the need to use tricks like $(dequote "" $&{client_name} $)
to cause the ${client_name} macro to be properly tokenized.
Add the MaxRecipientsPerMessage option: this limits the number of
recipients that will be accepted in a single SMTP
transaction. After this number is reached, sendmail
starts returning "452 Too many recipients" to all RCPT
commands. This can be used to limit the number of recipients
per envelope (in particular, to discourage use of the server
for spamming). Note: a better approach is to restrict
relaying entirely.
Fixed pointer initialization for LDAP lmap struct, fixed -s option
to ldapx map and added timeout for ldap_open call to
avoid hanging sendmail in the event of hung LDAP servers.
Patch from Booker Bense of Stanford University.
Allow multiple -qI, -qR, or -qS queue run limiters. For example,
'-qRfoo -qRbar' would deliver mail to recipients with foo or
bar in their address. Patch from Allan E Johannesen of
Worcester Polytechnic Institute.
The bestmx map will now return a list of the MX servers for a host if
passed a column delimiter via the -z map flag. This can be
used to check if the server is an MX server for the recipient
of a message. This can be used to help prevent relaying.
Patch from Mitchell Blank Jr of Exec-PC.
Mark failures for the *file* mailer and return bounce messages to the
sender for those failures.
Prevent bogus syslog timestamps on errors in sendmail.cf by
preserving the TZ environment variable until TimeZoneSpec
has been determined. Problem noted by Ralf Hildebrandt of
Technical University of Braunschweig. Patch from Per Hedeland
of Ericsson.
Print test input in address test mode when input is not from the tty
when the -v flag is given (i.e., sendmail -bt -v) to make
output easier to decipher. Problem noted by Aidan Nichol
of Procter & Gamble.
The LDAP map -s flag was not properly parsed and the error message
given included the remainder of the arguments instead of
solely the argument in error. Problem noted by Aidan Nichol
of Procter & Gamble.
New DontBlameSendmail option. This option allows administrators to
bypass some of sendmail's file security checks at the expense
of system security. This should only be used if you are
absolutely sure you know the consequences. The available
DontBlameSendmail options are:

New DontProbeInterfaces option to turn off the inclusion of all the
interface names in $=w on startup. In particular, if you
have lots of virtual interfaces, this option will speed up
startup. However, unless you make other arrangements, mail
sent to those addresses will be bounced.
Automatically create alias databases if they don't exist and
AutoRebuildAliases is set.
Add PrivacyOptions=noetrn flag to disable the SMTP ETRN command.
Suggested by Christophe Wolfhugel of the Institut Pasteur.
Add PrivacyOptions=noverb flag to disable the SMTP VERB command.
When determining the client host name ($&{client_name} macro), do
a forward (A) DNS lookup on the result of the PTR lookup
and compare results. If they differ or if the PTR lookup
fails, &{client_name} will contain the IP address
surrounded by square brackets (e.g., [127.0.0.1]).
New map flag: -Tx appends "x" to lookups that return temporary failure
(i.e, it is like -ax for the temporary failure case, in
contrast to the success case).
New syntax to do limited checking of header syntax. A config line
of the form:
HHeader: $>Ruleset
causes the indicated Ruleset to be invoked on the Header
when read. This ruleset works like the check_* rulesets --
that is, it can reject mail on the basis of the contents.
Limit the size of the HELO/EHLO parameter to prevent spammers
from hiding their connection information in Received:
headers.
When SingleThreadDelivery is active, deliveries to locked hosts
are skipped. This will cause the delivering process to
try the next MX host or queue the message if no other MX
hosts are available. Suggested by Alexander Litvin.
The [FILE] mailer type now delivers to the file specified in the
A= equate of the mailer definition instead of $u. It also
obeys all of the F= mailer flags such as the MIME
7/8 bit conversion flags. This is useful for defining
a mailer which delivers to the same file regardless of the
recipient (e.g., 'A=FILE /dev/null' to discard unwanted mail).
Do not assume the identity of a remote connection is root@localhost
if the remote connection closes the socket before the
remote identity can be queried.
Change semantics of the F=S mailer flag back to 8.7.5 behavior.
Some mailers, including procmail, require that the real
uid is left unchanged by sendmail. Problem noted by Per
Hedeland of Ericsson.
No longer is the src/obj*/Makefile selected from a large list -- it
is now generated using the information in BuildTools/OS/ --
some of the details are determined dynamically via
BuildTools/bin/configure.sh.
The other programs in the sendmail distribution -- mail.local,
mailstats, makemap, praliases, rmail, and smrsh -- now use
the new Build method which creates an operating system
specific Makefile using the information in BuildTools.
Make 4xx reply codes to the SMTP MAIL command be non-sticky (i.e.,
a failure on one message won't affect future messages to the
same host). This is necessary if the remote host sends
a 451 error if the domain of the sender does not resolve
as is common in anti-spam configurations. Problem noted
by Mitchell Blank Jr of Exec-PC.
New "discard" mailer for check_* rulesets and header checking
rulesets. If one of the above rulesets resolves to the
$#discard mailer, the commands will be accepted but the
message will be completely discarded after it is accepting.
This means that even if only one of the recipients
resolves to the $#discard mailer, none of the recipients
will receive the mail. Suggested by Brian Kantor.
All but the last cloned envelope of a split envelope were queued
instead of being delivered. Problem noted by John Caruso
of CNET: The Computer Network.
Fix deadlock situation in persistent host status file locking.
Syslog an error if a user forward file could not be read due to
an error. Patch from John Beck of Sun Microsystems.
Use the first name returned on machine lookups when canonifying a
hostname via NetInfo. Patch from Timm Wetzel of GWDG.
Clear the $&{client_addr}, $&{client_name}, and $&{client_port}
macros when delivering a bounce message to prevent
rejection by a check_compat ruleset which uses these macros.
Problem noted by Jens Hamisch of AgiX Internetservices GmbH.
If the check_relay ruleset resolves to the the error mailer, the
error in the $: portion of the resolved triplet is used
in the rejection message given to the remote machine.
Suggested by Scott Gifford of The Internet Ramp.
Set the $&{client_addr}, $&{client_name}, and $&{client_port} macros
before calling the check_relay ruleset. Suggested by Scott
Gifford of The Internet Ramp.
Sendmail would get a segmentation fault if a mailer exited with an
exit code of 79. Problem noted by Aaron Schrab of ExecPC
Internet. Fix from Christophe Wolfhugel of the Pasteur
Institute.
Separate snprintf/vsnprintf routines into separate file for use by
mail.local.
Allow multiple map lookups on right hand side, e.g.,
R$* $( host $1 $) $| $( passwd $1 $). Patch from
Christophe Wolfhugel of the Pasteur Institute.
Properly generate success DSN messages if requested for aliases
which have owner- aliases. Problem noted by Kari Hurtta
of the Finnish Meteorological Institute.
Properly display delayed-expansion macros ($&{macroname}) in
address test mode (-bt). Problem noted by Bryan Costales
of InfoBeat, Inc.
-qR could sometimes match names incorrectly. Problem noted by
Lutz Euler of Lavielle EDV Systemberatung GmbH & Co.
Include a magic number and version in the StatusFile for the
mailstats command.
Record the number of rejected and discarded messages in the
StatusFile for display by the mailstats command. Patch
from Randall Winchester of the University of Maryland.
IDENT returns where the OSTYPE field equals "OTHER" now list the
user portion as IDENT:username@site instead of
username@site to differentiate the two. Suggested by
Kari Hurtta of the Finnish Meteorological Institute.
Enforce timeout for LDAP queries. Patch from Per Hedeland of
Ericsson.
Change persistent host status filename substitution so '/' is
replaced by ':' instead of '|' to avoid clashes. Also
avoid clashes with hostnames with leading dots. Fix from
Mitchell Blank Jr. of Exec-PC.
If the system lock table is full, only attempt to create a new
queue entry five times before giving up. Previously, it
was attempted indefinitely which could cause the partition
to run out of inodes. Problem noted by Suzie Weigand of
Stratus Computer, Inc.
In verbose mode, warn if the sendmail.cf version is less than the
currently supported version.
Sorting for QueueSortOrder=host is now case insensitive. Patch
from Randall S. Winchester of the University of Maryland.
Properly quote a full name passed via the -F command line option,
the Full-Name: header, or the NAME environment variable if
it contains characters which must be quoted. Problem noted
by Kari Hurtta of the Finnish Meteorological Institute.
Avoid possible race condition that unlocked a mail job before
releasing the transcript file on systems that use flock(2).
In some cases, this might result in a "Transcript Unavailable"
message in error bounces.
Accept SMTP replies which contain only a reply code and no
accompanying text. Problem noted by Fernando Fraticelli of
Digital Equipment Corporation.
Portability:
AIX 4.1 uses int for SOCKADDR_LEN_T from Motonori Nakamura
of Kyoto University.

QNX from Glen McCready <glen@qnx.com>.
SCO 4.2 and 5.x use /usr/bin instead of /usr/ucb for links
to sendmail. Install with group bin instead of kmem
as kmem does not exist. From Guillermo Freige of
Gobernacion de la Pcia de Buenos Aires and Paul
Fischer of BTG, Inc.
SunOS 4.X does not include memmove(). Patch from
Per Hedeland of Ericsson.
SunOS 5.7 includes getloadavg() function for determining
load average. Patch from John Beck of Sun
Microsystems.
CONFIG: Increment version number of config file.
CONFIG: add DATABASE_MAP_TYPE to set the default type of database
map for the various maps. The default is hash. Patch from
Robert Harker of Harker Systems.
CONFIG: new confEBINDIR m4 variable for defining the executable
directory for certain programs.
CONFIG: new FEATURE(local_lmtp) to use the new LMTP support for
local mail delivery. By the default, /usr/libexec/mail.local
is used. This is expected to be the mail.local shipped
with 8.9 which is LMTP capable. The path is based on the
new confEBINDIR m4 variable.
CONFIG: Use confEBINDIR in determining path to smrsh for
FEATURE(smrsh). Note that this changes the default from
/usr/local/etc/smrsh to /usr/libexec/smrsh. To obtain the
old path for smrsh, use FEATURE(smrsh, /usr/local/etc/smrsh).
CONFIG: DOMAIN(generic) changes the default confFORWARD_PATH to
include $z/.forward.$w+$h and $z/.forward+$h which allow
the user to setup different .forward files for
user+detail addressing.
CONFIG: add confMAX_RCPTS_PER_MESSAGE, confDONT_PROBE_INTERFACES,
and confDONT_BLAME_SENDMAIL to set MaxRecipientsPerMessage,
DontProbeInterfaces, and DontBlameSendmail options.
CONFIG: by default do not allow relaying (that is, accepting mail
from outside your domain and sending it to another host
outside your domain).
CONFIG: new FEATURE(promiscuous_relay) to allow mail relaying from
any site to any site.
CONFIG: new FEATURE(relay_entire_domain) allows any host in your
domain as defined by the 'm' class ($=m) to relay.
CONFIG: new FEATURE(relay_based_on_MX) to allow relaying based on
the MX records of the host portion of an incoming recipient.
CONFIG: new FEATURE(access_db) which turns on the access database
feature. This database gives you the ability to allow
or refuse to accept mail from specified domains for
administrative reasons. By default, names that are listed
as "OK" in the access db are domain names, not host names.
CONFIG: new confCR_FILE m4 variable for defining the name of the file
used for class 'R'. Defaults to /etc/mail/relay-domains.
CONFIG: new command RELAY_DOMAIN(domain) and RELAY_DOMAIN_FILE(file)
to add items to class 'R' ($=R) for hosts allowed to relay.
CONFIG: new FEATURE(relay_hosts_only) to change the behavior
of FEATURE(access_db) and class 'R' to lookup individual
host names only.
CONFIG: new FEATURE(loose_relay_check). Normally, if a recipient
using % addressing is used, e.g. user%site@othersite,
and othersite is in class 'R', the check_rcpt ruleset
will strip @othersite and recheck user@site for relaying.
This feature changes that behavior. It should not be
needed for most installations.
CONFIG: new FEATURE(relay_local_from) to allow relaying if the
domain portion of the mail sender is a local host. This
should only be used if absolutely necessary as it opens
a window for spammers. Patch from Randall S. Winchester of
the University of Maryland.
CONFIG: new FEATURE(blacklist_recipients) turns on the ability to
block incoming mail destined for certain recipient
usernames, hostnames, or addresses.
CONFIG: By default, MAIL FROM: commands in the SMTP session will be
refused if the host part of the argument to MAIL FROM: cannot
be located in the host name service (e.g., DNS).
CONFIG: new FEATURE(accept_unresolvable_domains) accepts
unresolvable hostnames in MAIL FROM: SMTP commands.
CONFIG: new FEATURE(accept_unqualified_senders) accepts
MAIL FROM: senders which do not include a domain.
CONFIG: new FEATURE(rbl) Turns on rejection of hosts found in the
Realtime Blackhole List. You can specify the RBL name
server to contact by specifying it as an optional argument.
The default is rbl.maps.vix.com. For details, see
http://maps.vix.com/rbl/.
CONFIG: Call Local_check_relay, Local_check_mail, and
Local_check_rcpt from check_relay, check_mail, and
check_rcpt. Users with local rulesets should place the
rules using LOCAL_RULESETS. If a Local_check_* ruleset
returns $#OK, the message is accepted. If the ruleset
returns a mailer, the appropriate action is taken, else
the return of the ruleset is ignored.
CONFIG: CYRUS_MAILER_FLAGS now includes the /:| mailer flags by
default to support file, :include:, and program deliveries.
CONFIG: Remove the default for confDEF_USER_ID so the binary can
pick the proper default value. See the SECURITY note
above for more information.
CONFIG: FEATURE(nodns) now warns the user that the feature is a
no-op. Patch from Kari Hurtta of the Finnish
Meteorological Institute.
CONFIG: OSTYPE(osf1) now sets DefaultUser (confDEF_USER_ID) to
daemon since DEC's /bin/mail will drop the envelope
sender if run as mailnull. See the Digital UNIX section
of src/README for more information. Problem noted by
Kari Hurtta of the Finnish Meteorological Institute.
CONFIG: .cf files are now stored in the same directory with the
.mc files instead of in the obj directory.
CONFIG: New options confSINGLE_LINE_FROM_HEADER,
confALLOW_BOGUS_HELO, and confMUST_QUOTE_CHARS for
setting SingleLineFromHeader, AllowBogusHELO, and
MustQuoteChars respectively.
MAIL.LOCAL: support -l flag to run LMTP on stdin/stdout. This
SMTP-like protocol allows detailed reporting of delivery
status on a per-user basis. Code donated by John Myers of
CMU (now of Netscape).
MAIL.LOCAL: HP-UX support from Randall S. Winchester of the
University of Maryland. NOTE: mail.local is not
compatible with the stock HP-UX mail format. Be sure to
read mail.local/README.
MAIL.LOCAL: Prevent other mail delivery agents from stealing a
mailbox lock. Patch from Randall S. Winchester of the
University of Maryland.
MAIL.LOCAL: glibc portability from John Kennedy of Cal State
University, Chico.
MAIL.LOCAL: IRIX portability from Kari Hurtta of the Finnish
Meteorological Institute.
MAILSTATS: Display the number of rejected and discarded messages
in the StatusFile. Patch from Randall Winchester of the
University of Maryland.
MAKEMAP: New -s flag to ignore safety checks on database map files
such as linked files in world writable directories.
MAKEMAP: Add support for Berkeley DB 2.X. Remove OLD_NEWDB support.
PRALIASES: Add support for Berkeley DB 2.X.
PRALIASES: Do not automatically include NDBM support. Problem
noted by Ralf Hildebrandt of the Technical University of
Braunschweig.
RMAIL: Improve portability for other platforms. Patches from
Randall S. Winchester of the University of Maryland and
Kari Hurtta of the Finnish Meteorological Institute.

If the check_relay ruleset failed, the relay= field was logged
incorrectly. Problem noted by Kari Hurtta of the Finnish
Meteorological Institute.
If /usr/tmp/dead.letter already existed, sendmail could not
add additional bounces to it. Problem noted by Thomas J.
Arseneault of SRI International.
If an SMTP mailer used a non-standard port number for the outgoing
connection, it would be displayed incorrectly in verbose mode.
Problem noted by John Kennedy of Cal State University, Chico.
Log the ETRN parameter specified by the client before altering them
to internal form. Suggested by Bob Kupiec of GES-Verio.
EXPN and VRFY SMTP commands on malformed addresses were logging as
User unknown with bogus delay= values. Change them to log
the same as compliant addresses. Problem noted by Kari E.
Hurtta of the Finnish Meteorological Institute.
Ignore the debug resolver option unless using sendmail debug trace
option for resolver. Problem noted by Greg Nichols of Wind
River Systems.
If SingleThreadDelivery was enabled and the remote server returned a
protocol error on the DATA command, the connection would be
closed but the persistent host status file would not be
unlocked so other sendmail processes could not deliver to
that host. Problem noted by Peter Wemm of DIALix.
If queueing up a message due to an expensive mailer, don't increment
the number of delivery attempts or set the last delivery
attempt time so the message will be delivered on the next
queue run regardless of MinQueueAge. Problem noted by
Brian J. Coan of the Institute for Global Communications.
Authentication warnings of "Processed from queue _directory_" and
"Processed by _username_ with -C _filename_" would be logged
with the incorrect timestamp. Problem noted by Kari E. Hurtta
of the Finnish Meteorological Institute.
Use a better heuristic for detecting GDBM.
Log null connections on dropped connections. Problem noted by
Jon Lewis of Florida Digital Turnpike.
If class dbm maps are rebuilt, sendmail will now detect this and
reopen the map. Previously, they could give stale
results during a single message processing (but would
recover when the next message was received). Fix from
Joe Pruett of Q7 Enterprises.
Do not log failures such as "User unknown" on -bv or SMTP VRFY
requests. Problem noted by Kari E. Hurtta of the
Finnish Meteorological Institute.
Do not send a bounce message back to the sender regarding bad
recipients if the SMTP connection is dropped before the
message is accepted. Problem noted by Kari E. Hurtta of the
Finnish Meteorological Institute.
Use "localhost" instead of "[UNIX: localhost]" when connecting to
sendmail via a UNIX pipe. This will allow rulesets using
$&{client_name} to process without sending the string through
dequote. Problem noted by Alan Barrett of Internet Africa.
A combination of deferred delivery mode, a double bounce situation,
and the inability to save a bounce message to
/var/tmp/dead.letter would cause sendmail to send a bounce
to postmaster but not remove the offending envelope from the
queue causing it to create a new bounce message each time the
queue was run. Problem noted by Brad Doctor of Net Daemons
Associates.
Remove newlines from hostname information returned via DNS. There are
no known security implications of newlines in hostnames as
sendmail filters newlines in all vital areas; however, this
could cause confusing error messages.
Starting with sendmail 8.8.6, mail sent with the '-t' option would be
rejected if any of the specified addresses were bad. This
behavior was modified to only reject the bad addresses and not
the entire message. Problem noted by Jozsef Hollosi of
SuperNet, Inc.
Use Timeout.fileopen when delivering mail to a file. Suggested by
Bryan Costales of InfoBeat, Inc.
Display the proper Final-Recipient on DSN messages for non-SMTP
mailers. Problem noted by Kari E. Hurtta of the
Finnish Meteorological Institute.
An error in calculating the available space in the list of addresses
for logging deliveries could cause an address to be silently
dropped.
Include the initial user environment if sendmail is restarted via
a HUP signal. This will give room for the process title.
Problem noted by Jon Lewis of Florida Digital Turnpike.
Mail could be delivered without a body if the machine does not
support flock locking and runs out of processes during
delivery. Fix from Chuck Lever of the University of Michigan.
Drop recipient address from 251 and 551 SMTP responses per RFC 821.
Problem noted by Kari E. Hurtta of the Finnish Meteorological
Institute.
Make sure non-rebuildable database maps are opened before the
rebuildable maps (i.e., alias files) in case the database maps
are needed for verifying the left hand side of the aliases.
Problem noted by Lloyd Parkes of Victoria University.
Make sure sender RFC822 source route addresses are alias expanded for
bounce messages. Problem noted by Juergen Georgi of
RUS University of Stuttgart.
Minor lint fixes.
Return a temporary error instead of a permanent error if an LDAP map
search returns an error. This will allow sequenced maps which
use other LDAP servers to be checked. Fix from Booker Bense
of Stanford University.
When automatically converting from quoted printable to 8bit text do
not pad bare linefeeds with a space. Problem noted by Theo
Nolte of the University of Technology Aachen, Germany.
Portability:
Non-standard C compilers may have had a problem compiling
conf.c due to a standard C external declaration of
setproctitle(). Problem noted by Ted Roberts of
Electronic Data Systems.
AUX: has a broken O_EXCL implementation. Reported by Jim
Jagielski of jaguNET Access Services.
BSD/OS: didn't compile if HASSETUSERCONTEXT was defined.
Digital UNIX: Digital UNIX (and possibly others) moves
loader environment variables into the loader memory
area. If one of these environment variables (such as
LD_LIBRARY_PATH) was the last environment variable,
an invalid memory address would be used by the process
title routine causing memory corruption. Problem
noted by Sam Hartman of Mesa Internet Systems.
GNU libc: uses an enum for _PC_CHOWN_RESTRICTED which caused
chownsafe() to always return 0 even if the OS does
not permit file giveaways. Problem noted by
Yasutaka Sumi of The University of Tokyo.
IRIX6: Syslog buffer size set to 512 bytes. Reported by
Gerald Rinske of Siemens Business Services VAS.
Linux: Pad process title with NULLs. Problem noted by
Jon Lewis of Florida Digital Turnpike.
SCO OpenServer 5.0: SIOCGIFCONF ioctl call returns an
incorrect value for the number of interfaces.
Problem noted by Chris Loelke of JetStream Internet
Services.
SINIX: Update for Makefile and syslog buffer size from Gerald
Rinske of Siemens Business Services VAS.
Solaris: Make sure HASGETUSERSHELL setting for SunOS is not
used on a Solaris machine. Problem noted by
Stephen Ma of Jtec Pty Limited.
CONFIG: SINIX: Update from Gerald Rinske of Siemens Business

OP.ME: Document the F=i mailer flag. Problem noted by Per Hedeland of
Ericsson.
8.8.7/8.8.7 1997/08/03
If using Berkeley DB on systems without O_EXLOCK (open a file with
an exclusive lock already set -- i.e., almost all systems
except 4.4-BSD derived systems), the initial attempt at
rebuilding aliases file if the database didn't already
exist would fail. Patch from Raymund Will of LST Software
GmbH.
Bogus incoming SMTP commands would reset the SMTP conversation.
Problem noted by Fredrik Jönsson of the Royal Institute
of Technology, Stockholm.
Since TCP Wrappers includes setenv(), unsetenv(), and putenv(),
some environments could give "multiple definitions" for these
routines during compilation. If using TCP Wrappers, assume
that these routines are included as though they were in the
C library. Patch from Robert La Ferla.
When a NEWDB database map was rebuilt at the same time it was being
used by a queue run, the maps could be left locked for the
duration of the queue run, causing other processes to hang.
Problem noted by Kendall Libby of Shore.NET.
In some cases, NoRecipientAction=add-bcc was being ignored, so the
mail was passed on without any recipient header. This could
cause problems downstream. Problem noted by Xander Jansen
of SURFnet ExpertiseCentrum.
Give error when GDBM is used with sendmail. GDBM's locking and
linking of the .dir and .pag files interferes with sendmail's
locking and security checks. Problems noted by Fyodor
Yarochkin of the Kyrgyz Republic FreeNet.
Don't fsync qf files if SuperSafe option is not set.
Avoid extra calls to gethostbyname for addresses for which a
gethostbyaddr found no value. Also, ignore any returns
from gethostbyaddr that look like a dotted quad.
If PTR lookup fails when looking up an SMTP peer, don't tag it as
"may be forged", since at the network level we pretty much
have to assume that the information is good.
In some cases, errors during an SMTP session could leave files
open or locked.
Better handling of missing file descriptors (0, 1, 2) on startup.
Better handling of non-set-user-ID binaries -- avoids certain obnoxious
errors during testing.
Errors in file locking of NEWDB maps had the incorrect file name
printed in the error message.
If the AllowBogusHELO option were set and an EHLO with a bad or
missing parameter were issued, the EHLO behaved like a HELO.
Load limiting never kicked in for incoming SMTP transactions if the
DeliveryMode=background and any recipient was an alias or
had a .forward file. From Nik Conwell of Boston University.
On some non-Posix systems, the decision of whether chown(2) permits
file giveaway was undefined. From Tetsu Ushijima of the
Tokyo Institute of Technology.
Fix race condition that could cause the body of a message to be
lost (so only the header was delivered). This only occurs
on systems that do not use flock(2), and only when a queue
runner runs during a critical section in another message
delivery. Based on a patch from Steve Schweinhart of
Results Computing.
If a qf file was found in a mail queue directory that had a problem
(wrong ownership, bad format, etc.) and the file name was
exactly MAXQFNAME bytes long, then instead of being tried
once, it would be tried on every queue run. Problem noted
by Bryan Costales of Mercury Mail.
If the system supports an st_gen field in the status structure,
include it when reporting that a file has changed after open.
This adds a new compile flag, HAS_ST_GEN (0/1 option).
This out to be checked as well as reported, since it is
theoretically possible for an attacker to remove a file after
it is opened and replace it with another file that has the
same i-number, but some filesystems (notably AFS) return
garbage in this field, and hence always look like the file
has changed. As a practical matter this is not a security
problem, since the files can be neither hard nor soft links,
and on no filesystem (that I am aware of) is it possible to
have two files on the same filesystem with the same i-number
simultaneously.
Delete the root Makefile from the distribution -- it is only for
use internally, and does not work at customer sites.
Fix botch that caused the second MAIL FROM: command in a single
transaction to clear the entire transaction. Problem
noted by John Kennedy of Cal State University, Chico.
Work properly on machines that have _PATH_VARTMP defined without
a trailing slash. (And a pox on vendors that decide to
ignore the established conventions!) Problem noted by
Gregory Neil Shapiro of WPI.
Internal changes to make it easier to add another protocol family
(intended for IPv6). Patches are from John Kennedy of
CSU Chico.
In certain cases, 7->8 bit MIME decoding of Base64 text could leave
an extra space at the beginning of some lines. Problem
noted by Charles Karney of Princeton University; fix based
on a patch from Christophe Wolfhugel.
Portability:
Allow _PATH_VENDOR_CF to be set in Makefile for consistency
with the _Sendmail_ book, 2nd edition. Note that
the book is actually wrong: _PATH_SENDMAILCF should
be used instead.
AIX 3.x: Include <sys/select.h>. Patch from Gene Rackow
of Argonne National Laboratory.
OpenBSD from from Paul DuBois of the University of Wisconsin.
RISC/os 4.0 from Paul DuBois of the University of Wisconsin.
SunOS: Include <memory.h> to fix warning from util.c. From
James Aldridge of EUnet Ltd.
Solaris: Change STDIR (location of status file) to /etc/mail
in Makefiles.
Linux, Dynix, UNICOS: Remove -DNDBM and -lgdbm from
Makefiles. Use NEWDB on Linux instead.
NCR MP-RAS 3.x with STREAMware TCP/IP: SIOCGIFNUM ioctl
exists but behaves differently than other OSes.
Add SIOCGIFNUM_IS_BROKEN compile flag to get
around the problem. Problem noted by Tom Moore of
NCR Corp.

getsockname, and getsockopt. Adds new compile flags
SOCKADDR_SIZE_T and SOCKOPT_SIZE_T. Problem reported
by Tom Good of St. Vincent's North Richmond Community
Mental Health Center Residential Services.
AIX 4: Use size_t for SOCKADDR_SIZE_T and SOCKOPT_SIZE_T.
Suggested by Brett Hogden of Rochester Gas & Electric
Corp.
Linux: avoid compile problem for versions of <setjmp.h> that
#define both setjmp and longjmp. Problem pointed out
by J.R. Oldroyd of TerraNet.
CONFIG: SCO UnixWare 2.1: Support for OSTYPE(sco-uw-2.1)

CONFIG: MAILER(fax) called a program that hasn't existed for a long
time. Convert to use the HylaFAX 4.0 conventions. Suggested
by Harry Styron.
CONFIG: Improve sample anti-spam rulesets in cf/cf/knecht.mc. These
are the rulesets in use on sendmail.org.
MAKEMAP: give error on GDBM files.

*************************************************************
SECURITY: A few systems allow an open with the O_EXCL|O_CREAT open
mode bits set to create a file that is a symbolic link that
points nowhere. This makes it possible to create a root
owned file in an arbitrary directory by inserting the symlink
into a writable directory after the initial lstat(2) check
determined that the file did not exist. The only verified
example of a system having these odd semantics for O_EXCL
and symbolic links was HP-UX prior to version 9.07. Most
systems do not have the problem, since a exclusive create
of a file disallows symbolic links. Systems that have been
verified to NOT have the problem include AIX 3.x, *BSD,
DEC OSF/1, HP-UX 9.07 and higher, Linux, SunOS, Solaris,
and Ultrix. This is a potential exposure on systems that
have this bug and which do not have a MAILER-DAEMON alias
pointing at a legitimate account, since this will cause old
mail to be dropped in /var/tmp/dead.letter.
SECURITY: Problems can occur on poorly managed systems, specifically,
if maps or alias files are in world writable directories.
If your system has alias maps in writable directories, it
is potentially possible for an attacker to replace the .db
(or .dir and .pag) files by symbolic links pointing at
another database; this can be used either to expose
information (e.g., by pointing an alias file at /etc/spwd.db
and probing for accounts), or as a denial-of-service attack
(by trashing the password database). The fix disallows
symbolic links entirely when rebuilding alias files or on
maps that are in writable directories, and always warns on
writable directories; 8.9 will probably consider writable
directories to be fatal errors. This does not represent an
exposure on systems that have alias files in unwritable
system directories.
SECURITY: disallow .forward or :include: files that are links (hard
or soft) if the parent directory (or any directory in the
path) is writable by anyone other than the owner. This is
similar to the previous case for user files. This change
should not affect most systems, but is necessary to prevent
an attacker who can write the directory from pointing such
files at other files that are readable only by the owner.
SECURITY: Tighten safechown rules: many systems will say that they
have a safe (restricted to root) chown even on files that
are mounted from another system that allows owners to give
away files. The new rules are very strict, trusting file
ownership only in those few cases where the system has
been verified to be at least as paranoid as necessary.
However, it is possible to relax the rules to partially
trust the ownership if the directory path is not world or
group writable. This might allow someone who has a legitimate
:include: file (referenced directly from /etc/aliases) to
become another non-root user if the :include: file is in a
non-writable directory on an NFS-mounted filesystem where
the local system says that giveaway is denied but it is
actually permitted. I believe this to be a very small set
of cases. If in doubt, do not point :include: aliases at
NFS-mounted filesystems.
SECURITY: When setting a numeric group id using the RunAsUser option
(e.g., "O RunAsUser=10:20", the group id would not be set.
Implicit group ids (e.g., "O RunAsUser=mailnull") or alpha
group ids (e.g., "O RunAsUser=mailuser:mailgrp") worked fine.
The user id was still set properly. Problem noted by Uli
Pralle of the Technical University of Berlin.
Save the initial gid set for use when checking for if the
PrivacyOptions=restrictmailq option is set. Problem reported
by Wolfgang Ley of DFN-CERT.
Make 55x reply codes to the SMTP DATA-"." be non-sticky (i.e., a
failure on one message won't affect future messages to the
same host).
IP source route printing had an "off by one" error that would
affect any options that came after the route option. Patch
from Theo de Raadt.
The "Message is too large" error didn't successfully bounce the error
back to the sender. Problem reported by Stephen More of
PSI; patch from Gregory Neil Shapiro of WPI.
Change SMTP status code 553 to map into Extended code 5.1.0 (instead
of 5.1.3); it apparently gets used in multiple ways.
Suggested by John Myers of Portola Communications.
Fix possible extra null byte generated during collection if errors
occur at the beginning of the stream. Patch contributed by
Andrey A. Chernov and Gregory Neil Shapiro.
Code changes to avoid possible reentrant call of malloc/free within
a signal handler. Problem noted by John Beck of Sun
Microsystems.
Move map initialization to be earlier so that check_relay ruleset
will have the latest version of the map data. Problem noted
by Paul Forgey of Metainfo; patch from Gregory Neil Shapiro.
If there are fatal errors during the collection phase (e.g., message
too large) don't send the bogus message.
Avoid "cannot open xfAAA00000" messages when sending to aliases that
have errors and have owner- aliases. Problem noted by Michael
Barber of MTU; fix from Gregory Neil Shapiro of WPI.
Avoid null pointer dereference on illegal Boundary= parameters in
multipart/mixed Content-Type: header. Problem noted by
Richard Muirden of RMIT University.
Always print error messages during newaliases (-bi) even if the
ErrorMode is not set to "print". Fix from Gregory Neil
Shapiro.
Test mode could core dump if you did a /map lookup in an optional map
that could not be opened. Based on a fix from John Beck of
Sun Microsystems.
If DNS is misconfigured so that the last MX record tried points to
a host that does not have an A record, but other MX records
pointed to something reasonable, don't bounce the message
with a "host unknown" error. Note that this should really
be fixed in the zone file for the domain. Problem noted by
Joe Rhett of Navigist, Inc.
If a map fails (e.g., DNS times out) on all recipient addresses, mark
the message as having been tried; otherwise the next queue
run will not realize that this is a second attempt and will
retry immediately. Problem noted by Bryan Costales of
Mercury Mail.
If the clock is set backwards, and a MinQueueAge is set, no jobs
will be run until the later setting of the clock is reached.
"Problem" (I use the term loosely) noted by Eric Hagberg of
Morgan Stanley.
If the load average rises above the cutoff threshold (above which
sendmail will not process the queue at all) during a queue
run, abort the queue run immediately. Problem noted by
Bryan Costales of Mercury Mail.
The variable queue processing algorithm (based on the message size,
number of recipients, message precedence, and job age) was
non-functional -- either the entire queue was processed or
none of the queue was processed. The updated algorithm
does no queue run if a single recipient zero size job will
not be run.
If there is a fatal ("panic") message that will cause sendmail to
die immediately, never hold the error message for future
printing.
Force ErrorMode=print in -bt mode so that all errors are printed
regardless of the setting of the ErrorMode option in the
configuration file. Patch from Gregory Neil Shapiro.
New compile flag HASSTRERROR says that this OS has the strerror(3)
routine available in one of the libraries. Use it in conf.h.
The -m (match only) flag now works on host class maps.
If class hash or btree maps are rebuilt, sendmail will now detect
this and reopen the map. Previously, they could give
erroneous results during a single message processing
(but would recover when the next message was received).
Don't delete zero length queue files when doing queue runs until the
files are at least ten minutes old. This avoids a potential
race condition: the creator creates the qf file, getting back
a file descriptor. The queue runner locks it and deletes it
because it is zero length. The creator then writes the
descriptor that is now for a disconnected file, and the
job goes away. Based on a suggestion by Bryan Costales.
When determining the "validated" host name ($_ macro), do a forward
(A) DNS lookup on the result of the PTR lookup and compare
results. If they differ or if the PTR lookup fails, tag the
address as "may be forged".
Log null connections (i.e., hosts that connect but do not do any
substantive activity on the connection before disconnecting;
"substantive" is defined to be MAIL, EXPN, VRFY, or ETRN.
Always permit "writes" to /dev/null regardless of the link count.
This is safe because /dev/null is special cased, and no open
or write is ever actually attempted. Patch from Villy Kruse
of TwinCom.
If a message cannot be sent because of a 552 (exceeded storage
allocation) response to the MAIL FROM:<>, and a SIZE= parameter
was given, don't return the body in the bounce, since there
is a very good chance that the message will double-bounce.
Fix possible line truncation if a quoted-printable had an =00 escape
in the body. Problem noted by Charles Karney of the Princeton
Plasma Physics Laboratory.
Notify flags (e.g., -NSUCCESS) were lost on user+detail addresses.
Problem noted by Kari Hurtta of the Finnish Meteorological
Institute.
The MaxDaemonChildren option wasn't applying to queue runs as
documented. Note that this increases the potential denial
of service problems with this option: an attacker can
connect many times, and thereby lock out queue runs as well
as incoming connections. If you use this option, you should
run the "sendmail -bd" and "sendmail -q30m" jobs separately
to avoid this attack. Failure to limit noted by Matthew
Dillon of BEST Internet Communications.
Always give a message in newaliases if alias files cannot be
opened instead of failing silently. Suggested by Gregory
Neil Shapiro. This change makes the code match the O'Reilly
book (2nd edition).
Some older versions of the resolver could return with h_errno == -1
if no name server could be reached, causing mail to bounce
instead of queueing. Treat this like TRY_AGAIN. Fix from
John Beck of SunSoft.
If a :include: file is owned by a user that does not have an entry
in the passwd file, sendmail could dereference a null pointer.
Problem noted by Satish Mynam of Sun Microsystems.
Take precautions to make sure that the SMTP protocol cannot get out
of sync if (for example) an alias file cannot be opened.
Fix a possible race condition that can cause a SIGALRM to come in
immediately after a SIGHUP, causing the new sendmail to die.
Avoid possible hang on SVr3 systems when doing child reaping. Patch
from Villy Kruse of TwinCom.
Ignore improperly formatted SMTP reply codes. Previously these were
partially processed, which could cause confusing error
returns.
Fix possible bogus pointer dereference when doing ldapx map lookups
on some architectures.
Portability:
A/UX: from Jim Jagielski of NASA/GSFC.
glibc: SOCK_STREAM was changed from a #define to an enum,
thus breaking #ifdef SOCK_STREAM. Only option seems
to be to assume SOCK_STREAM if __GNU_LIBRARY__ is
defined. Problem reported by A Sun of the University
of Washington.
Solaris: use SIOCGIFNUM to get the number of interfaces on
the system rather than guessing at compile time.
Patch contributed by John Beck of Sun Microsystems.
Intel Paragon: from Wendy Lin of Purdue University.
GNU Hurd: from Miles Bader of the GNU project.
RISC/os 4.50 from Harlan Stenn of PFCS Corporation.
ISC Unix: wait never returns if SIGCLD signals are blocked.
Unfortunately releasing them opens a race condition,
but there appears to be no fix for this. Patch from
Gregory Neil Shapiro.
BIND 8.1 for IPv6 compatibility from John Kennedy.
Solaris: a bug in strcasecmp caused characters with the
high order bit set to apparently randomly match
letters -- for example, $| (0233) matches "i" and "I".
Problem noted by John Gregson of the University of
Cambridge.
IRIX 6.x: make Makefile.IRIX.6.2 apply to all 6.x. From
Kari Hurtta.
IRIX 6.x: Create Makefiles for systems that claim to be
IRIX64 but are 6.2 or higher (so use the regular
IRIX Makefile).
IRIX 6.x: Fix load average computation on 64 bit kernels.
Problem noted by Eric Hagberg of Morgan Stanley.
CONFIG: Some canonification was still done for UUCP-like addresses
even if FEATURE(nocanonify) was set. Problem pointed out by
Brian Candler.
CONFIG: In some cases UUCP mailers wouldn't properly recognize all
local names as local. Problem noted by Jeff Polk of BSDI;
fix provided by Gregory Neil Shapiro.
CONFIG: The "local:user" syntax entries in mailertables and other
"mailer:user" syntax locations returned an incorrect value
for the $h macro. Problem noted by Gregory Neil Shapiro.
CONFIG: Retain "+detail" information when forwarding mail to a
MAIL_HUB, LUSER_RELAY, or LOCAL_RELAY. Patch from Philip
Guenther of Gustavus Adolphus College.
CONFIG: Make sure user+detail works for FEATURE(virtusertable);
rules are the same as for aliasing. Based on a patch from
Gregory Neil Shapiro.
CONFIG: Break up parsing rules into several pieces; this should
have no functional change in this release, but makes it
possible to have better anti-spam rulesets in the future.
CONFIG: Disallow double dots in host names to avoid having the
HostStatusDirectory store status under the wrong name.
In some cases this can be used as a denial-of-service attack.
Problem noted by Ron Jarrell of Virginia Tech, patch from
Gregory Neil Shapiro.
CONFIG: Don't use F=m (multiple recipients per invocation) for
MAILER(procmail), but do pass F=Pn9 (include Return-Path:,
don't include From_, and convert to 8-bit). Suggestions
from Kimmo Suominen and Roderick Schertler.
CONFIG: Domains under $=M (specified with MASQUERADE_DOMAIN) were
being masqueraded as though FEATURE(masquerade_entire_domain)
was specified, even when it wasn't.
MAIL.LOCAL: Solaris 2.6 has snprintf. From John Beck of SunSoft.
MAIL.LOCAL: SECURITY: check to make sure that an attacker doesn't
"slip in" a symbolic link between the lstat(2) call and the
exclusive open. This is only a problem on System V derived
systems that allow an exclusive create on files that are
symbolic links pointing nowhere.
MAIL.LOCAL: If the final mailbox close() failed, the user id was
not reset back to root, which on some systems would cause
later mailboxes to fail. Also, any partial message would
not be truncated, which could result in repeated deliveries.
Problem noted by Bruce Evans via Peter Wemm (FreeBSD
developers).
MAKEMAP: Handle cases where O_EXLOCK is #defined to be 0. A similar
change to the sendmail map code was made in 8.8.3. Problem
noted by Gregory Neil Shapiro.
MAKEMAP: Give warnings on file problems such as map files that are
symbolic links; although makemap is not set-user-ID root, it is
often run as root and hence has the potential for the same
sorts of problems as alias rebuilds.
MAKEMAP: Change compilation so that it will link properly on
NEXTSTEP.
CONTRIB: etrn.pl: search for Cw as well as Fw lines in sendmail.cf.
Accept an optional list of arguments following the server
name for the ETRN arguments to use (instead of $=w). Other
miscellaneous bug fixes. From Christian von Roques via
John Beck of Sun Microsystems.
CONTRIB: Add passwd-to-alias.pl, contributed by Kari Hurtta. This
Perl script converts GECOS information in the /etc/passwd
file into aliases, allowing for faster access to full name
lookups; it is also clever about adding aliases (to root)
for system accounts.

SECURITY: Clear out group list during startup. Without this, sendmail
will continue to run with the group permissions of the caller,
even if RunAsUser is specified.
SECURITY: Make purgestat (-bH) be root-only. This is not in response
to any known attack, but it's best to be conservative.
Suggested by Peter Wemm of DIALix.
SECURITY: Fix buffer overrun problem in MIME code that has possible
security implications. Patch from Alex Garthwaite of the
University of Pennsylvania.
Use of a -f flag with a phrase attached (e.g., "-f 'Full Name <addr>'")
would truncate the address after "Full". Although the -f
syntax is incorrect (since it is in the envelope, it
shouldn't have comments and full names), the failure mode
was unnecessarily awful.
Fix a possible null pointer dereference when converting 8-bit data
to a 7-bit format. Problem noted by Jim Hutchins of
Sandia National Labs and David James of British Telecom.
Clear out stale state that affected F=9 on SMTP mailers in queue
runs. Although this really shouldn't be used (F=9 is for
final delivery only, and using it on an SMTP mailer makes
it possible for a message to be converted from 8->7->8->7
bits several times), it shouldn't have failed with a syserr.
Problem noted by Eric Hagberg of Morgan Stanley.
_Really_ fix the multiple :maildrop code in the user database
module. Patch from Roy Mongiovi of Georgia Tech.
Let F lines in the configuration file actually read root-only
files if the configuration file is safe. Based on a
patch from Keith Reynolds of SCO.
ETRN followed by QUIT would hold the connection open until the queue
run completed. Problem noted by Truck Lewis of TDK
Semiconductor Corp.
It turns out that despite the documentation, the TCP wrappers library
does _not_ log rejected connections. Do the logging ourselves.
Problem noted by Fletcher Mattox of the University of Texas
at Austin.
If sendmail finds a qf file in its queue directory that is an unknown
version (e.g., when backing out to an old version), the
error is reported on every queue run. Change it to only
give the error once (and rename the qf => Qf). Patch from
William A. Gianopoulos of Raytheon Company.
Start a new session when doing background delivery; currently it
ignored signals but didn't start a new signal, that caused
some problems if a background process tried to send mail
under certain circumstances. Problem noted by Eric Hagberg
of Morgan Stanley; fix from Kari Hurtta.
Simplify test for skipping a queue run to just check if the current
load average is >= the queueing load average. Previously
the check factored in some other parameters that caused it
to essentially never skip the queue run. Patch from Bryan
Costales.
If the SMTP server is running in "nullserver" mode (that is, it is
rejecting all commands), start sleeping after MAXBADCOMMAND
(25) commands; this helps prevent a bad guy from putting
you into a tight loop as a denial-of-service attack. Based
on an e-mail conversation with Brad Knowles of AOL.
Slow down when too many "light weight" commands have been issued;
this helps prevent a class of denial-of-service attacks.
The current values and defaults are:
MAXNOOPCOMMANDS 20 NOOP, VERB, ONEX, XUSR
MAXHELOCOMMANDS 3 HELO, EHLO
MAXVRFYCOMMANDS 6 VRFY, EXPN
MAXETRNCOMMANDS 8 ETRN
These will probably be configurable in a future release.
On systems that have uid_t typedefed to be an unsigned short, programs
that had the F=S flag and no U= equate would be invoked with
the real uid set to 65535 rather than being left unchanged.
In some cases, NOTIFY=NEVER was not being honored. Problem noted
by Steve Hubert of the University of Washington, Seattle.
Mail that was Quoted-Printable encoded and had a soft line break on
the last line (i.e., an incomplete continuation) had the last
line dropped. Since this appears to be illegal it isn't
clear what to do with it, but flushing the last line seems
to be a better "fail soft" approach. Based on a patch from
Eric Hagberg.
If AllowBogusHELO and PrivacyOptions=needmailhelo are both set, a
bogus HELO command still causes the "Polite people say HELO
first" error message. Problem pointed out by Chris Thomas
of UCLA; patch from John Beck of SunSoft.
Handle "sendmail -bp -qSfoobar" properly if restrictqrun is set
in PrivacyOptions. The -q shouldn't turn this command off.
Problem noted by Murray Kucherawy of Pacific Bell Internet;
based on a patch from Gregory Neil Shapiro of WPI.
Don't consider SMTP reply codes 452 or 552 (exceeded storage allocation)
in a DATA transaction to be sticky; these can occur because
a message is too large, and smaller messages should still go
through. Problem noted by Matt Dillon of Best Internet
Communications.
In some cases bounces were saved in /var/tmp/dead.letter even if they
had been successfully delivered to the envelope sender.
Problem noted Eric Hagberg of Morgan Stanley; solution from
Gregory Neil Shapiro of WPI.
Give better diagnostics on long alias lines. Based on code contributed
by Patrick Gosling of the University of Cambridge.
Increase the number of virtual interfaces that will be probed for
alternate names. Problem noted by Amy Rich of Shore.Net.

CONFIG: It seems that I hadn't gotten the Received: line syntax
_just_right_ yet. Tweak it again. I'll omit the names
of the "contributors" (quantity two) in this one case.
As of now, NO MORE DISCUSSION about the syntax of the
Received: line.
CONFIG: Although FEATURE(nullclient) uses EXPOSED_USER (class $=E),
it never inserts that class into the output file. Fix it
so it will honor EXPOSED_USER but will _not_ include root
automatically in this class. Problem noted by Ronan KERYELL
of Centre de Recherche en Informatique de l'École Nationale
Supérieure des Mines de Paris (CRI-ENSMP).
CONFIG: Clean up handling of "local:" syntax in relay specifications
such as LUSER_RELAY. This change permits the following
syntaxes: ``local:'' will send to the same user on the
local machine (e.g., in a mailertable entry for "host",
``local:'' will cause an address addressed to user@host to
go to user on the local machone). ``local:user'' will send
to the named user on the local machine. ``local:user@host''
is equivalent to ``local:user'' (the host is ignored). In
all cases, the original user@host is passed in $@ (i.e., the
detail information). Inspired by a report from Michael Fuhr.
CONFIG: Strip quotes from the first word of an "error:" host
indication. This lets you set (for example) the LUSER_RELAY
to be ``error:\"5.1.1\" Your Message Here''. Note the use
of the \" so that the resulting string is properly quoted.
Problem noted by Gregory Neil Shapiro of WPI.
OP.ME: documentation was inconsistent about whether sendmail did a
NOOP or a RSET to probe the connection (it does a RSET).
Inconsistency noted by Deeran Peethamparam.
OP.ME: insert additional blank pages so it will print properly on
a duplex printer. From Matthew Black of Cal State University,
Long Beach.
8.8.4/8.8.4 1996/12/02
SECURITY: under some circumstances, an attacker could get additional
permissions by hard linking to files that were group
writable by the attacker. The solution is to disallow any
files that have hard links -- this will affect .forward,
:include:, and output files. Problem noted by Terry
Kyriacopoulos of Interlog Internet Services. As a
workaround, set UnsafeGroupWrites -- always a good idea.
SECURITY: the TryNullMXList (w) option should not be safe -- if it
is, it is possible to do a denial-of-service attack on
MX hosts that rely on the use of the null MX list. There
is no danger if you have this option turned off (the default).
Problem noted by Dan Bernstein. Also, make the DontInitGroups
unsafe. I know of no specific attack against this, although
a denial-of-service attack is probably possible, but in theory
you should not be able to safely tweak anything that affects
the permissions that are used when mail is delivered.
Purgestat could go into an infinite loop if one of the host status
directories somehow became empty. Problem noted by Roy
Mongiovi of Georgia Tech.
Processes got "lost" when counting children due to a race condition.
This caused "proc_list_probe: lost pid" messages to be logged.
Problem noted by several people.
On systems with System V SIGCLD child signal semantics (notably AIX
and HP-UX), mail transactions would print the message "451
SMTP-MAIL: lost child: No child processes". Problem noted
by several people.
Miscellaneous compiler warnings on picky compilers (or when setting
gcc to high warning levels). From Tom Moore of NCR Corp.
SMTP protocol errors, and most errors on MAIL FROM: lines should
not be persistent between runs, since they are based on the
message rather than the host. Problem noted by Matt Dillon
of Best Internet Communications.
The F=7 flag was ignored on SMTP mailers. Problem noted by Tom Moore
of NCR (a.k.a., AT&T Global Information Solutions).
Avoid the possibility of having a child daemon run to completion
(including closing the SMTP socket) before the parent has
had a chance to close the socket; this can cause the parent
to hang for a long time waiting for the socket to drain.
Patch from Don Lewis of TDK Semiconductor.
If the fork() failed in a queue run, the queue runners would not be
rescheduled (so queue runs would stop). Patch from Don Lewis.
Some error conditions in ETRN could cause output without an SMTP
status code. Problem noted by Don Lewis.
Multiple :maildrop addresses in the user database didn't work properly.
Patch from Roy Mongiovi of Georgia Tech.
Add ".db" automatically onto any user database spec that does not
already have it; this is for consistency with makemap, the
K line, and the documentation. Inconsistency pointed out
by Roy Mongiovi.
Allow sendmail to be properly called in nohup mode. Patch from
Kyle Jones of UUNET.
Change ETRN to ignore but still update host status files; previously
it would ignore them and not save the updated status, which
caused stale information to be maintained. Based on a patch
from Christopher Davis of Kapor Enterprises Inc. Also, have
ETRN ignore the MinQueueAge option.
Patch long term host status to recover more gracefully from an empty
host status file condition. Patch from NAKAMURA Motonori
of Kyoto University.
Several patches to signal handling code to fix potential race
conditions from Don Lewis.
Make it possible to compile with -DDAEMON=0 (previously it had some
compile errors). This turns DAEMON, QUEUE, and SMTP into
0/1 compilation flags. Note that DAEMON is an obsolete
compile flag; use NETINET instead. Solution based on a
patch from Bryan Costales.
PORTABILITY FIXES:
AIX4: getpwnam() and getpwuid() do a sequential scan of the
/etc/security/passwd file when called as root. This
is very slow on some systems. To speed it up, use the
(undocumented) _getpw{nam,uid}_shadow() routines.
Patch from Chris Thomas of UCLA/OAC Systems Group.
SCO 5.x: include -lprot in the Makefile. Patch from Bill
Glicker of Burrelle's Information Service.
NEWS-OS 4.x: need a definition for MODE_T to compile. Patch
from Makoto MATSUSHITA of Osaka University.
SunOS 4.0.3: compile problems. Patches from Andrew Cole of
Leeds University and SASABE Tetsuro of the University
of Tokyo.
DG/UX 5.4.4.11 from Brian J. Murrell of InterLinx Support
Services, Inc.
Domain/OS from Don (Truck) Lewis of TDK Semiconductor Corp.
I believe this to have only been a problem if you
compiled with -DUSE_VENDOR_CF_PATH -- another reason
to stick with /etc/sendmail.cf as your One True Path.
Digital UNIX (OSF/1 on Alpha) load average computation from
Martin Laubach of the Technischen Universität Wien.
CONFIG: change default Received: line to be multiple lines rather
than one long one. By popular demand.
MAIL.LOCAL: warnings weren't being logged on some systems. Patch
from Jerome Berkman of U.C. Berkeley.
MAKEMAP: be sure to zero hinfo to avoid cruft that can cause runs
to take a very long time. Problem noted by Yoshiro YONEYA
of NTT Software Corporation.
CONTRIB: add etrn.pl, contributed by John Beck.
NEW FILES:
contrib/etrn.pl
8.8.3/8.8.3 1996/11/17
SECURITY: it was possible to get a root shell by lying to sendmail
about argv[0] and then sending it a signal. Problem noted
by Leshka Zakharoff <leshka@leshka.chuvashia.su> on the
best-of-security list.
Log sendmail binary version number in "Warning: .cf version level
(%d) exceeds program functionality (%d) message" -- this
should make it clearer to people that they are running
the wrong binary.
Fix a problem that occurs when you open an SMTP connection and then
do one or more ETRN commands followed by a MAIL command; at
the end of the DATA phase sendmail would incorrectly report
"451 SMTP-MAIL: lost child: No child processes". Problem
noted by Eric Bishop of Virginia Tech.
When doing text-based host canonification (typically /etc/hosts
lookup), a null host name would match any /etc/hosts entry
with space at the end of the line. Problem noted by Steve
Hubert of the University of Washington, Seattle.
7 to 8 bit BASE64 MIME conversions could duplicate bits of text.
Problem reported by Tom Smith of Digital Equipment Corp.
Increase the size of the DNS answer buffer -- the standard UDP packet
size PACKETSZ (512) is not sufficient for some nameserver
answers containing very many resource records. The resolver
may also switch to TCP and retry if it detects UDP packet
overflow. Also, allow for the fact that the resolver
routines res_query and res_search return the size of the
*un*truncated answer in case the supplied answer buffer it
not big enough to accommodate the entire answer. Patch from
Eric Wassenaar.
Improvements to MaxDaemonChildren code. If you think you have too
many children, probe the ones you have to verify that they
are still around. Suggested by Jared Mauch of CICnet, Inc.
Also, do this probe before growing the vector of children
pids; this previously caused the vector to grow indefinitely
due to a race condition. Problem reported by Kyle Jones of
UUNET.
On some architectures, <db.h> (from the Berkeley DB library) defines
O_EXLOCK to zero; this fools the map compilation code into
thinking that it can avoid race conditions by locking on open.
Change it to check for O_EXLOCK non-zero. Problem noted by
Leif Erlingsson of Data Lege.
Always call res_init() on startup (if compiled in, of course) to
allow the sendmail.cf file to tweak resolver flags; without
it, flag tweaks in ResolverOptions are ignored. Patch from
Andrew Sun of Merrill Lynch.
Improvements to host status printing code. Suggested by Steve Hubert
of the University of Washington, Seattle.
Change MinQueueAge option processing to do the check for the job age
when reading the queue file, rather than at the end; this
avoids parsing the addresses, which can do DNS lookups.
Problem noted by John Beck of InReference, Inc.
When MIME was being 7->8 bit decoded, "From " lines weren't being
properly escaped. Problem noted by Peter Nilsson of the
University of Linkoping.
In some cases, sendmail would retain root permissions during queue
runs even if RunAsUser was set. Problem noted by Mark
Thomas of Mark G. Thomas Consulting.
If the F=l flag was set on an SMTP mailer to indicate that it is
actually local delivery, and NOTIFY=SUCCESS is specified in
the envelope, and the receiving SMTP server speaks DSN, then
the DSN would be both generated locally and propagated to the
other end.
The U= mailer field didn't correctly extract the group id if the
user id was numeric. Problem noted by Kenneth Herron of
MCI Telecommunications Communications.
If a message exceeded the fixed maximum size on input, the body of
the message was included in the bounce. Note that this did
not occur if it exceeded the maximum _output_ size. Problem
reported by Kyle Jones of UUNET.
PORTABILITY FIXES:
AIX4: 4.1 doesn't have a working setreuid(2); change the
AIX4 defines to use seteuid(2) instead, which
works on 4.1 as well as 4.2. Problem noted by
Håkan Lindholm of interAF, Sweden.
AIX4: use tzname[] vector to determine time zone name.
Patch from NAKAMURA Motonori of Kyoto University.
MkLinux: add Makefile.Linux.ppc and OSTYPE(mklinux) support.
Contributed by Paul DuBois <dubois@primate.wisc.edu>.
Solaris: kstat(3k) support for retrieving the load average.
This adds the LA_KSTAT definition for LA_TYPE.
The outline of the implementation was contributed
by Michael Tokarev of Telecom Service, JSC, Moscow.
HP-UX 10.0 gripes about the (perfectly legal!) forward
declaration of struct rusage at the top of conf.h;
change it to only be included if you are using gcc,
which is apparently the only compiler that requires
it in the first place. Problem noted by Jeff
Earickson of Colby College.
IRIX: don't default to using gcc. IRIX is a civilized
operating system that comes with a decent compiler
by default. Problem noted by Barry Bouwsma and
Kari Hurtta.
CONFIG: specify F=9 as default in FEATURE(local_procmail) for
consistency with other local mailers. Inconsistency
pointed out by Teddy Hogeborn <teddy@fukt.hk-r.se>.
CONFIG: if the "limited best mx" feature is used (to reduce DNS
overhead) as part of the bestmx_is_local feature, the
domain part was dropped from the name. Patch from Steve
Hubert of the University of Washington, Seattle.
CONFIG: catch addresses of the form "user@.dom.ain"; these could
end up being translated to the null host name, which would
return any entry in /etc/hosts that had a space at the end
of the line. Problem noted by Steve Hubert of the
University of Washington, Seattle.
CONFIG: add OSTYPE(aix4). From Michael Sofka of Rensselaer
Polytechnic Institute.
MAKEMAP: tweak hash and btree parameters for better performance.
Patch from Matt Dillon of Best Internet Communications.
NEW FILES:
src/Makefiles/Makefile.Linux.ppc

cf/ostype/mklinux.m4
8.8.2/8.8.2 1996/10/18
SECURITY: fix a botch in the 7-bit MIME patch; the previous patch
changed the code but didn't fix the problem.
PORTABILITY FIXES:
Solaris: Don't use the system getusershell(3); it can
apparently corrupt the heap in some circumstances.
Problem found by Ken Pizzini of Spry, Inc.
OP.ME: document several mailer flags that were accidentally omitted
from this document. These flags were F=d, F=j, F=R, and F=9.
CONFIG: no changes.
8.8.1/8.8.1 1996/10/17
SECURITY: unset all environment variables that the resolver will
examine during queue runs and daemon mode. Problem noted
by Dan Bernstein of the University of Illinois at Chicago.
SECURITY: in some cases an illegal 7-bit MIME-encoded text/plain
message could overflow a buffer if it was converted back
to 8 bits. This caused core dumps and has the potential
for a remote attack. Problem first noted by Gregory Shapiro
of WPI.
Avoid duplicate deliveries of error messages on systems that don't
have flock(2) support. Patch from Motonori Nakamura of
Kyoto University.
Ignore null FallBackMX (V) options. If this option is null (as
opposed to undefined) it can cause "null signature" syserrs
on illegal host names.
If a Base64 encoded text/plain message has no trailing newline in
the encoded text, conversion back to 8 bits will drop the
final line. Problem noted by Pierre David.
If running with a RunAsUser, sendmail would give bogus "cannot
setuid" (or seteuid, or setreuid) messages on some systems.
Problem pointed out by Jordan Mendelson of Web Services, Inc.
Always print error messages in -bv mode -- previously, -bv would
be absolutely silent on errors if the error mode was sent
to (say) mail-back. Problem noted by Kyle Jones of UUNET.
If -qI/R/S is set (or the ETRN command is used), ignore all long
term host status. This is necessary because it is common
to do this when you know a host has just come back up.
Disallow duplicate HELO/EHLO commands as required by RFC 1651 section
4.2. Excessive permissiveness noted by Lee Flight of the
University of Leicester.
If a service (such as NIS) is specified as the last entry in the
service switch, but that service is not compiled in, sendmail
would return a temporary failure when an entry was not found
in the map. This caused the message to be queued instead of
bouncing immediately. Problem noted by Harry Edmon of the
University of Washington.
PORTABILITY FIXES:
Solaris 2.3 had compilation problems in conf.c. Several
people pointed this out.
NetBSD from Charles Hannum of MIT.
AIX4 improvements based on info from Steve Bauer of South
Dakota School of Mines & Technology.
CONFIG: ``error:code message'' syntax was broken in virtusertable.
Patch from Gil Kloepfer Jr.
CONFIG: if FEATURE(nocanonify) was specified, hosts in $=M (set
using MASQUERADE_DOMAIN) were not masqueraded unless they
were also in $=w. Problem noted by Zoltan Basti of
Softec.
MAIL.LOCAL: patches to compile and link cleanly on AIX. Based
on a patch from Eric Hagberg of Morgan Stanley.
MAIL.LOCAL: patches to compile on NEXTSTEP. From Patrick Nolan
of Stanford via Robert La Ferla.
8.8.0/8.8.0 1996/09/26
Under some circumstances, Bcc: headers would not be properly
deleted. Pointed out by Jonathan Kamens of OpenVision.
Log a warning if the sendmail daemon is invoked without a full
pathname, which prevents "kill -1" from working. I was
urged to put this in by Andrey A. Chernov of DEMOS (Russia).
Fix small buffer overflow. Since the data in this buffer was not
read externally, there was no security problem (and in fact
probably wouldn't really overflow on most compilers). Pointed
out by KIZU takashi of Osaka University.
Fix problem causing domain literals such as [1.2.3.4] to be ignored
if a FallbackMXHost was specified in the configuration file
-- all mail would be sent to the fallback even if the original
host was accessible. Pointed out by Munenari Hirayama of
NSC (Japan).
A message that didn't terminate with a newline would (sometimes) not
have the trailing "." added properly in the SMTP dialogue,
causing SMTP to hang. Patch from Per Hedeland of Ericsson.
The DaemonPortOptions suboption to bind to a particular address was
incorrect and nonfunctional due to a misunderstanding of the
semantics of binding on a passive socket. Patch from
NIIBE Yutaka of Mitsubishi Research Institute.
Increase the number of MX hosts for a single name to 100 to better
handle the truly huge service providers such as AOL, which
has 13 at the moment (and climbing). In order to avoid
trashing memory, the buffer for all names has only been
slightly increased in size, to 12.8K from 10.2K -- this means
that if a single name had 100 MX records, the average size
of those records could not exceed 128 bytes. Requested by
Brad Knowles of America On Line.
Restore use of IDENT returns where the OSTYPE field equals "OTHER".
Urged by Dan Bernstein of U.C. Berkeley.
Print q_statdate and q_specificity in address structure debugging
printout.
Expand MCI structure flag bits for debugging output.
Support IPv6-style domain literals, which can have colons between
square braces.
Log open file descriptors for the "cannot dup" messages in deliver();
this is an attempt to track down a bug that one person seems
to be having (it may be a Solaris bug!).
DSN NOTIFY parameters were not properly propagated across queue runs;
this caused the NOTIFY info to sometimes be lost. Problem
pointed out by Claus Assmann of the
Christian-Albrechts-University of Kiel.
The statistics gathered in the sendmail.st file were too high; in
some cases failures (e.g., user unknown or temporary failure)
would count as a delivery as far as the statistics were
concerned. Problem noted by Tom Moore of AT&T GIS.
Systems that don't have flock() would not send split envelopes in
the initial run. Problem pointed out by Leonard Zubkoff of
Dandelion Digital.
Move buffer overflow checking -- these primarily involve distrusting
results that may come from NIS and DNS.
4.4-BSD-derived systems, including FreeBSD, NetBSD, and BSD/OS didn't
include <paths.h> and hence had the wrong pathnames for a few
things like /var/tmp. Reported by Matthew Green.
Conditions were reversed for the Priority: header, resulting in all
values being interpreted as non-urgent except for non-urgent,
which was interpreted as normal. Patch from Bryan Costales.
The -o (optional) flag was being ignored on hash and btree maps
since 8.7.2. Fix from Bryan Costales.
Content-Types listed in class "q" will always be encoded as
Quoted-Printable (or more accurately, will never be encoded
as base64). The class can have primary types (e.g., "text")
or full types (e.g., "text/plain"). Based on a suggestion by
Marius Olafsson of the University of Iceland.
Define ${envid} to be the original envelope id (from the ESMTP DSN
dialogue) so it can be passed to programs in mailers.
Define ${bodytype} to be the body type (from the -B flag or the
BODY= ESMTP parameter) so it can be passed to programs in
mailers.
Cause the VRFY command to return 252 instead of 250 unless the F=q
flag is set in the mailer descriptor. Suggested by John
Myers of CMU.
Implement ESMTP ETRN command to flush the queue for a specific host.
The command takes a host name; data for that host is
immediately (and asynchronously) flushed. Because this shares
the -qR implementation, other hosts may be attempted, but
there should be no security implications. Implementation
from John Beck of InReference, Inc. See RFC 1985 for details.
Add three new command line flags to pass in DSN parameters: -V envid
(equivalent to ENVID=envid on the MAIL command), -R ret
(equivalent to RET=ret on the MAIL command), and -Nnotify
(equivalent to NOTIFY=notify on the RCPT command). Note
that the -N flag applies to all recipients; there is no way
to specify per-address notifications on the command line,
nor is there an equivalent for the ORCPT= per-address
parameter.
Restore LogLevel option to be safe (it can only be increased);
apparently I went into paranoid mode between 8.6 and 8.7
and made it unsafe. Pointed out by Dabe Murphy of the
University of Maryland.
New logging on log level 15: all SMTP traffic. Patches from
Andrew Gross of San Diego Supercomputer Center.
NetInfo property value searching code wasn't stopping when it found
a match. This was causing the wrong values to be found (and
had a memory leak). Found by Bastian Schleuter of TU-Berlin.
Add new F=0 (zero) mailer flag to turn off MX lookups. It was pointed
out by Bill Wisner of Electronics for Imaging that you can't
use the bracket address form for the MAIL_HUB macro, since
that causes the brackets to remain in the envelope recipient
address used for delivery. The simple fix (stripping off the
brackets in the config file) breaks the use of IP literal
addresses. This flag will solve that problem.
Add MustQuoteChars option. This is a list of characters that must
be quoted if they are found in the phrase part of an address
(that is, the full name part). The characters @,;:\()[] are
always in this list and cannot be removed. The default is
this list plus . and ' to match RFC 822.
Add AllowBogusHELO option; if set, sendmail will allow HELO commands
that do not include a host name for back compatibility with
some stupid SMTP clients. Setting this violates RFC 1123
section 5.2.5.
Add MaxDaemonChildren option; if this is set, sendmail will start
rejecting connections if it has more than this many
outstanding children accepting mail. Note that you may
see more processes than this because of outgoing mail; this
is for incoming connections only.
Add ConnectionRateThrottle option. If set to a positive value, the
number of incoming SMTP connections that will be permitted
in a single second is limited to this number. Connections are
not refused during this time, just deferred. The intent is to
flatten out demand so that load average limiting can kick in.
It is less radical than MaxDaemonChildren, which will stop
accepting connections even if all the connections are idle
(e.g., due to connection caching).
Add Timeout.hoststatus option. This interval (defaulting to 30m)
specifies how long cached information about the state of a
host will be kept before they are considered stale and the
host is retried. If you are using persistent host status
(i.e., the HostStatusDirectory option is set) this will apply
between runs; otherwise, it applies only within a single queue
run and hence is useful only for hosts that have large queues
that take a very long time to run.
Add SingleLineFromHeader option. If set, From: headers are coerced
into being a single line even if they had newlines in them
when read. This is to get around a botch in Lotus Notes.
Text class maps were totally broken -- if you ever retrieved the last
item in a table it would be truncated. Problem noted by
Gregory Neil Shapiro of WPI.
Extend the lines printed by the mailq command (== the -bp flag) when
-v is given to 120 characters; this allows more information
to be displayed. Suggested by Gregory Neil Shapiro of WPI.
Allow macro definitions (`D' lines) with unquoted commas; previously
this was treated as end-of-input. Problem noted by Bryan
Costales.
The RET= envelope parameter (used for DSNs) wasn't properly written
to the queue file. Fix from John Hughes of Atlantic
Technologies, Inc.
Close /var/tmp/dead.letter after a successful write -- otherwise
if this happens in a queue run it can cause nasty delays.
Problem noted by Mark Horton of AT&T.
If userdb entries pointed to userdb entries, and there were multiple
values for a given key, the database cursor would get
trashed by the recursive call. Problem noted by Roy Mongiovi
of Georgia Tech. Fixed by reading all the values and creating
a comma-separated list; thus, the -v output will be somewhat
different for this case.
Fix buffer allocation problem with Hesiod-based userdb maps when
HES_GETMAILHOST is defined. Based on a patch by Betty Lee
of Stanford University.
When envelopes were split due to aliases with owner- aliases, and
there was some error on one of the lists, more than one of
the owners would get the message. Problem pointed out by
Roy Mongiovi of Georgia Tech.
Detect excessive recursion in macro expansions, e.g., $X defined
in terms of $Y which is defined in terms of $X. Problem
noted by Bryan Costales; patch from Eric Wassenaar.
When using F=U to get "ugly UUCP" From_ lines, a buffer could in
some cases get trashed causing bogus From_ lines. Fix from
Kyle Jones of UUNET.
When doing load average initialization, if the nlist call for avenrun
failed, the second and subsequent lookups wouldn't notice
that fact causing bogus load averages to be returned. Noted
by Casper Dik of Sun Holland.
Fix problem with incompatibility with some versions of inet_aton that
have changed the return value to unsigned, so a check for an
error return of -1 doesn't work. Use INADDR_NONE instead.
This could cause mail to addresses such as [foo.com] to bounce
or get dropped. Problem noted by Christophe Wolfhugel of the
Pasteur Institute.
DSNs were inconsistent if a failure occurred during the DATA phase
rather than the RCPT phase: the Action: would be correct, but
the detailed status information would be wrong. Problem noted
by Bob Snyder of General Electric Company.
Add -U command line flag and the XUSR ESMTP extension, both indicating
that this is the initial MUA->MTA submission. The flag current
does nothing, but in future releases (when MUAs start using
these flags) it will probably turn on things like DNS
canonification.
Default end-of-line string (E= specification on mailer [M] lines)
to \r\n on SMTP mailers. Default remains \n on non-SMTP
mailers.
Change the internal definition for the *file* and *include* mailers
to have $u in the argument vectors so that they aren't
misinterpreted as SMTP mailers and thus use \r\n line
termination. This will affect anyone who has redefined
either of these in their configuration file.
Don't assume that IDENT servers close the connection after a query;
responses can be newline terminated. From Terry Kennedy of
St. Peter's College.
Avoid core dumps on erroneous configuration files that have
$#mailer with nothing following. From Bryan Costales.
Avoid null pointer dereference with high debug values in unlockqueue.
Fix from Randy Martin of Clemson University.
Fix possible buffer overrun when expanding very large macros. Fix
from Kyle Jones of UUNET.
After 25 EXPN or VRFY commands, start pausing for a second before
processing each one. This avoids a certain form of denial
of service attack. Potential attack pointed out by Bryan
Costales.
Allow new named (not numbered!) config file rules to do validity
checking on SMTP arguments: check_mail for MAIL commands and
check_rcpt for RCPT commands. These rulesets can do anything
they want; their result is ignored unless they resolve to the
$#error mailer, in which case the indicated message is printed
and the command is rejected. Similarly, the check_compat
ruleset is called before delivery with "from_addr $| to_addr"
(the $| is a meta-symbol used to separate the two addresses);
it can give a "this sender can't send to this recipient"
notification. Note that this patch allows $| to stand alone
in rulesets.
Define new macros ${client_name}, ${client_addr}, and ${client_port}
that have the name, IP address, and port number (respectively)
of the SMTP client (that is, the entity at the other end of
the connection. These can be used in (e.g.) check_rcpt to
verify that someone isn't trying to relay mail through your
host inappropriately. Be sure to use the deferred evaluation
form, for example $&{client_name}, to avoid having these bound
when sendmail reads the configuration file.
Add new config file rule check_relay to check the incoming connection
information. Like check_compat, it is passed the host name
and host address separated by $| and can reject connections
on that basis.
Allow IDA-style recursive function calls. Code contributed by Mark
Lovell and Paul Vixie.
Eliminate the "No ! in UUCP From address!" message" -- instead, create
a virtual UUCP address using either a domain address or the $k
macro. Based on code contributed by Mark Lovell and Paul
Vixie.
Add Stanford LDAP map. Requires special libraries that are not
included with sendmail. Contributed by Booker C. Bense
<bbense@networking.stanford.edu>; contact him for support.
See also the src/READ_ME file.
Allow -dANSI to turn on ANSI escape sequences in debug output; this
puts metasymbols (e.g., $+) in reverse video. Really useful
only for debugging deep bits of code where it is important to
distinguish between the single-character metasymbol $+ and the
two characters $, +.
Changed ruleset 89 (executed in dumpstate()) to a named ruleset,
debug_dumpstate.
Add new UnsafeGroupWrites option; if set, .forward and :include:
files that are group writable are considered "unsafe" -- that
is, programs and files referenced from such files are not
valid recipients.
Delete bogosity test for FallBackMX host; this prevented it to be a
name that was not in DNS or was a domain-literal. Problem
noted by Tom May.
Change the introduction to error messages to more clearly delineate
permanent from temporary failures; if both existed in a
single message it could be confusing. Suggested by John
Beck of InReference, Inc.
The IngoreDot (i) option didn't work for lines that were terminated
with CRLF. Problem noted by Ted Stockwell of Secure
Computing Corporation.
Add a heuristic to improve the handling of unbalanced `<' signs in
message headers. Problem reported by Matt Dillon of Best
Internet Communications.
Check for bogus characters in the 0200-0237 range; since these are
used internally, very strange errors can occur if those
characters appear in headers. Problem noted by Anders Gertz
of Lysator.
Implement 7 -> 8 bit MIME conversions. This only takes place if the
recipient mailer has the F=9 flag set, and only works on
text/plain body types. Code contributed by Marius Olafsson
of the University of Iceland.
Special case "postmaster" name so that it is always treated as lower
case in alias files regardless of configuration settings;
this prevents some potential problems where "Postmaster" or
"POSTMASTER" might not match "postmaster". In most cases
this change is a no-op.
The -o map flag was ignored for text maps. Problem noted by Bryan
Costales.
The -a map flag was ignored for dequote maps. Problem noted by
Bryan Costales.
Fix core dump when a lookup of a class "prog" map returns no
response. Patch from Bryan Costales.
Log instances where sendmail is deferring or rejecting connections
on LogLevel 14. Suggested by Kyle Jones of UUNET.
Include port number in process title for network daemons. Suggested
by Kyle Jones of UUNET.
Send ``double bounces'' (errors that occur when sending an error
message) to the address indicated in the DoubleBounceAddress
option (default: postmaster). Previously they were always
sent to postmaster. Suggested by Kyle Jones of UUNET.
Add new mode, -bD, that acts like -bd in all respects except that
it runs in foreground. This is useful for using with a
wrapper that "watches" system services. Suggested by Kyle
Jones of UUNET.
Fix botch in spacing around (parenthesized) comments in addresses
when the comment comes before the address. Patch from
Motonori Nakamura of Kyoto University.
Use the prefix "Postmaster notify" on the Subject: lines of messages
that are being bounced to postmaster, rather than "Returned
mail". This permits the person who is postmaster more
easily determine what messages are to their role as
postmaster versus bounces to mail they actually sent. Based
on a suggestion by Motonori Nakamura.
Add new value "time" for QueueSortOrder option; this causes the queue
to be sorted strictly by the time of submission. Note that
this can cause very bad behavior over slow lines (because
large jobs will tend to delay small jobs) and on nodes with
heavy traffic (because old things in the queue for hosts that
are down delay processing of new jobs). Also, this does not
guarantee that jobs will be delivered in submission order
unless you also set DeliveryMode=queue. In general, it should
probably only be used on the command line, and only in
conjunction with -qRhost.domain. In fact, there are very few
cases where it should be used at all. Based on an
implementation by Motonori Nakamura.
If a map lookup in ruleset 5 returns tempfail, queue the message in
the same manner as other rulesets. Previously a temporary
failure in ruleset 5 was ignored. Patch from Booker Bense
of Stanford University.
Don't proceed to the next MX host if an SMTP MAIL command returns a
5yz (permanent failure) code. The next MX host will still be
tried if the connection cannot be opened in the first place
or if the MAIL command returns a 4yz (temporary failure) code.
(It's hard to know what to do here, since neither RFC 974 nor
RFC 1123 specify when to proceed to the next MX host.)
Suggested by Jonathan Kamens of OpenVision, Inc.
Add new "-t" flag for map definitions (the "K" line in the .cf file).
This causes map lookups that get a temporary failure (e.g.,
name server failure) to _not_ defer the delivery of the
message. This should only be used if your configuration file
is prepared to do something sensible in this case. Based on
an idea by Gregory Shapiro of WPI.
Fix problem finding network interface addresses. Patch from
Motonori Nakamura.
Don't reject qf entries that are not owned by your effective uid if
you are not running set-user-ID; this makes management of
certain kinds of firewall setups difficult. Patch
suggested by Eamonn Coleman of Qualcomm.
Add persistent host status. This keeps the information normally
maintained within a single queue run in disk files that are
shared between sendmail instances. The HostStatusDirectory
is the directory in which the information is maintained. If
not set, persistent host status is turned off. If not a full
pathname, it is relative to the queue directory. A common
value is ".hoststat".
There are also two new operation modes:
* -bh prints the status of hosts that have had recent
connections.
* -bH purges the host statuses. No attempt is made to save
recent status information.
This feature was originally written by Paul Vixie of Vixie
Enterprises for KJS and adapted for V8 by Mark Lovell of
Bigrock Consulting. Paul's funding of Mark and Mark's patience
with my insistence that things fit cleanly into the V8
framework is gratefully appreciated.
New SingleThreadDelivery option (requires HostStatusDirectory to
operate). Avoids letting two sendmails on the local machine
open connections to the same remote host at the same time.
This reduces load on the other machine, but can cause mail to
be delayed (for example, if one sendmail is delivering a huge
message, other sendmails won't be able to send even small
messages). Also, it requires another file descriptor (for the
lock file) per connection, so you may have to reduce
ConnectionCacheSize to avoid running out of per-process
file descriptors. Based on the persistent host status code
contributed by Paul Vixie and Mark Lovell.
Allow sending to non-simple files (e.g., /dev/null) even if the
SafeFileEnvironment option is set. Problem noted by Bryan
Costales.
The -qR flag mistakenly matched flags in the "R" line of the queue
file. Problem noted by Bryan Costales.
If a job was aborted using the interrupt signal (e.g., control-C from
the keyboard), on some occasions an empty df file would be
left around; these would collect in the queue directory.
Problem noted by Bryan Costales.
Change the makesendmail script to enhance the search for Makefiles
based on release number. For example, on SunOS 5.5.1, it will
search for Makefile.SunOS.5.5.1, Makefile.SunOS.5.5, and then
Makefile.SunOS.5.x (in addition to the other rules, e.g.,
adding $arch). Problem noted by Jason Mastaler of Atlanta
Webmasters.
When creating maps using "newaliases", always map the keys to lower
case when creating the map unless the -f flag is specified on
the map itself. Previously this was done based on the F=u
flag in the local mailer, which meant you could create aliases
that you could never access. Problem noted by Bob Wu of DEC.
When a job was read from the queue, the bits causing notification on
failure or delay were always set. This caused those
notifications to be sent even if NOTIFY=NEVER had been
specified. Problem noted by Steve Hubert of the University
of Washington, Seattle.
Add new configurable routine validate_connection (in conf.c). This
lets you decide if you are willing to accept traffic from
this host. If it returns FALSE, all SMTP commands will return
"550 Access denied". -DTCPWRAPPERS will include support for
TCP wrappers; you will need to add -lwrap to the link line.
(See src/READ_ME for details.)
Don't include the "THIS IS A WARNING MESSAGE ONLY" banner on postmaster
bounces. Some people seemed to think that this could be
confusing (even though it is true). Suggested by Motonori
Nakamura.
Add new RunAsUser option; this causes sendmail to do a setuid to that
user early in processing to avoid potential security problems.
However, this means that all .forward and :include: files must
be readable by that user, and all files to be written must be
writable by that user and all programs will be executed by that
user. It is also incompatible with the SafeFileEnvironment
option. In other words, it may not actually add much to
security. However, it should be useful on firewalls and other
places where users don't have accounts and the aliases file is
well constrained.
Add Timeout.iconnect. This is like Timeout.connect except it is used
only on the first attempt to delivery to an address. It could
be set to be lower than Timeout.connect on the principle that
the mail should go through quickly to responsive hosts; less
responsive hosts get to wait for the next queue run.
Fix a problem on Solaris that occasionally causes programs
(such as vacation) to hang with their standard input connected
to a UDP port. It also created some signal handling problems.
The problems turned out to be an interaction between vfork(2)
and some of the libraries, particularly NIS/NIS+. I am
indebted to Tor Egge <tegge@idt.ntnu.no> for this fix.
Change user class map to do the same matching that actual delivery
will do instead of just a /etc/passwd lookup. This adds
fuzzy matching to the user map. Patch from Dan Oscarsson.
The Timeout.* options are not safe -- they can be used to create a
denial-of-service attack. Problem noted by Christophe
Wolfhugel.
Don't send PostmasterCopy messages in the event of a "delayed"
notification. Suggested by Barry Bouwsma.
Don't advertise "VERB" ESMTP extension if the "noexpn" privacy
option is set, since this disables VERB mode. Suggested
by John Hawkinson of MIT.
Complain if the QueueDirectory (Q) option is not set. Problem noted
by Motonori Nakamura of Kyoto University.
Only queue messages on transient .forward open failures if there
were no successful opens. The previous behavior caused it
to queue even if a "fall back" .forward was found. Problem
noted by Ann-Kian Yeo of the Dept. of Information Systems
and Computer Science (DISCS), NUS, Singapore.
Don't do 8->7 bit conversions when bouncing a MIME message that
is bouncing because of a MIME error during 8->7 bit conversion;
the encapsulated message will bounce again, causing a loop.
Problem noted by Steve Hubert of the University of Washington.
Create xf (transcript) files using the TempFileMode option value
instead of 0644. Suggested by Ann-Kian Yeo of the
National University of Singapore.
Print errors if setgid/setuid/etc. fail during delivery. This helps
detect cases where DefaultUser is set to something that the
system can't cope with.
PORTABILITY FIXES:
Support for AIX/RS 2.2.1 from Mark Whetzel of Western
Atlas International.
Patches for Intel Paragon OSF/1 1.3 from Leo Bicknell
<bicknell@ufp.org>.
On DEC OSF/1 3.2 and earlier, the MatchGECOS code would only
work on the first recipient of a message due to a
bug in the getpwent family. If this is something you
use, you can define DEC_OSF_BROKEN_GETPWENT=1 for a
workaround. From Maximum Entropy of Sanford C.

of the University of Arizona.
Solaris 2.5 has a working setreuid. Noted by David Linn of
Vanderbilt University.
Solaris changes for praliases, makemap, mailstats, and smrsh.
Previously you had to add -DSOLARIS in Makefile.dist;
this auto-detects. Based on a patch from Randall
Winchester of the University of Maryland.
CONFIG: add generic-nextstep3.3.mc file. Contributed by
Robert La Ferla of Hot Software.
CONFIG: allow mailertables to resolve to ``error:code message''
(where "code" is an exit status) on domains (previously
worked only on hosts). Patch from Cor Bosman of Xs4all
Foundation.
CONFIG: hooks for IPv6-style domain literals.
CONFIG: predefine ALIAS_FILE and change the prototype file so that
if it is undefined the AliasFile option is never set; this
should be transparent for most everyone. Suggested by John
Myers of CMU.
CONFIG: add FEATURE(limited_masquerade). Without this feature, any
domain listed in $=w is masqueraded. With it, only those
domains listed in a MASQUERADE_DOMAIN macro are masqueraded.
CONFIG: add FEATURE(masquerade_entire_domain). This causes
masquerading specified by MASQUERADE_DOMAIN to apply to all
hosts under those domains as well as the domain headers
themselves. For example, if a configuration had
MASQUERADE_DOMAIN(foo.com), then without this feature only
foo.com would be masqueraded; with it, *.foo.com would be
masqueraded as well. Based on an implementation by Richard
(Pug) Bainter of U. Texas.
CONFIG: add FEATURE(genericstable) to do a more general rewriting of
outgoing addresses. Defaults to ``hash -o /etc/genericstable''.
Keys are user names; values are outgoing mail addresses. Yes,
this does overlap with the user database, and figuring out
just when to use which one may be tricky. Based on code
contributed by Richard (Pug) Bainter of U. Texas with updates
from Per Hedeland of Ericsson.
CONFIG: add FEATURE(virtusertable) to do generalized rewriting of
incoming addresses. Defaults to ``hash -o /etc/virtusertable''.
Keys are either fully qualified addresses or just the host
part (with the @ sign). For example, a table containing:
info@foo.com foo-info
info@bar.com bar-info
@baz.org jane@elsewhere.net
would send all mail destined for info@foo.com to foo-info
(which is presumably an alias), mail addressed to info@bar.com
to bar-info, and anything addressed to anyone at baz.org will
be sent to jane@elsewhere.net. The names foo.com, bar.com,
and baz.org must all be in $=w. Based on discussions with
a great many people.
CONFIG: add nullclient configurations to define SMTP_MAILER_FLAGS.
Suggested by Richard Bainter.
CONFIG: add FAX_MAILER_ARGS to tweak the arguments passed to the
"fax" mailer.
CONFIG: allow mailertable entries to resolve to local:user; this
passes the original user@host in to procmail-style local
mailers as the "detail" information to allow them to do
additional clever processing. From Joe Pruett of
Teleport Corporation. Delivery to the original user can
be done by specifying "local:" (with nothing after the colon).
CONFIG: allow any context that takes "mailer:domain" to also take
"mailer:user@domain" to force mailing to the given user;
"local:user" can also be used to do local delivery. This
applies on *_RELAY and in the mailertable entries. Based
on a suggestion by Ribert Kiessling of Easynet.
CONFIG: Allow FEATURE(bestmx_is_local) to take an argument that
limits the possible domains; this reduces the number of DNS
lookups required to support this feature. For example,
FEATURE(bestmx_is_local, my.site.com) limits the lookups
to domains under my.site.com. Code contributed by Anthony
Thyssen <anthony@cit.gu.edu.au>.
CONFIG: LOCAL_RULESETS introduces any locally defined rulesets,
such as the check_rcpt ruleset. Suggested by Gregory Shapiro
of WPI.
CONFIG: MAILER_DEFINITIONS introduces any mailer definitions, in the
event you have to define local mailers. Suggested by
Gregory Shapiro of WPI.
CONFIG: fix cases where a three- (or more-) stage route-addr could
be misinterpreted as a list:...; syntax. Based on a patch by
Vlado Potisk <Vlado_Potisk@tempest.sk>.
CONFIG: Fix masquerading of UUCP addresses when the UUCP relay is
remotely connected. The address host!user was being
converted to host!user@thishost instead of host!user@uurelay.
Problem noted by William Gianopoulos of Raytheon Company.
CONFIG: add confTO_ICONNECT to set Timeout.iconnect.
CONFIG: change FEATURE(redirect) message from "User not local" to
"User has moved"; the former wording was confusing if the
new address is still on the local host. Based on a suggestion
by Andreas Luik.
CONFIG: add support in FEATURE(nullclient) for $=E (exposed users).
However, the class is not pre-initialized to contain root.
Suggested by Gregory Neil Shapiro.
CONTRIB: Remove XLA code at the request of the author, Christophe
Wolfhugel.
CONTRIB: Add re-mqueue.pl, contributed by Paul Pomes of Qualcomm.
MAIL.LOCAL: make it possible to compile mail.local on Solaris. Note
well: this produces a slightly different mailbox format (no
Content-Length: headers), file ownerships and modes are
different (not owned by group mail; mode 600 instead of 660),
and the local mailer flags will have to be tweaked (make them
match bsd4.4) in order to use this mailer. Patches from Paul
Hammann of the Missouri Research and Education Network.
MAIL.LOCAL: in some cases it could return EX_OK even though there
was a delivery error, such as if the ownership on the file
was wrong or the mode changed between the initial stat and
the open. Problem reported by William Colburn of the New
Mexico Institute of Mining and Technology.
MAILSTATS: handle zero length files more reliably. Patch from Bryan
Costales.
MAILSTATS: add man page contributed by Keith Bostic of BSDI.
MAKEMAP: The -d flag (to allow duplicate keys) to a btree map wasn't
honored. Fix from Michael Scott Shappe.
PRALIASES: add man page contributed by Keith Bostic of BSDI.

8.7.6/8.7.3 1996/09/17
SECURITY: It is possible to force getpwuid to fail when writing the
queue file, causing sendmail to fall back to running programs
as the default user. This is not exploitable from off-site.
Workarounds include using a unique user for the DefaultUser
(old u & g options) and using smrsh as the local shell.
SECURITY: fix some buffer overruns; in at least one case this allows
a local user to get root. This is not known to be exploitable
from off-site. The workaround is to disable chfn(1) commands.
8.7.5/8.7.3 1996/03/04
Fix glitch in 8.7.4 when putting certain internal lines; this can
in some case cause connections to hang or messages to have
extra spaces in odd places. Patch from Eric Wassenaar;
reports from Eric Hall of Chiron Corporation, Stephen
Hansen of Stanford University, Dean Gaudet of HotWired,
and others.
8.7.4/8.7.3 1996/02/18
SECURITY: In some cases it was still possible for an attacker to
insert newlines into a queue file, thus allowing access to
any user (except root).
CONFIG: no changes -- it is not a bug that the configuration
version number is unchanged.
8.7.3/8.7.3 1995/12/03
Fix botch in name server timeout in RCPT code; this problem caused
two responses in SMTP, which breaks things horribly. Fix
from Gregory Neil Shapiro of WPI.
Verify that L= value on M lines cannot be negative, which could cause
negative array subscripting. Not a security problem since
this has to be in the config file, but it could have caused
core dumps. Pointed out by Bryan Costales.
Fix -d21 debug output for long macro names. Pointed out by Bryan
Costales.
PORTABILITY FIXES:
SCO doesn't have ftruncate. From Bill Aten of Computerizers.
IBM's version of arpa/nameser.h defaults to the wrong byte
order. Tweak it to work properly. Based on fixes
from Fletcher Mattox of UTexas and Betty Lee of
Stanford University.
CONFIG: add confHOSTS_FILE m4 variable to set HostsFile option.
Deficiency pointed out by Bryan Costales of ICSI.
8.7.2/8.7.2 1995/11/19
REALLY fix the backslash escapes in SmtpGreetingMessage,
OperatorChars, and UnixFromLine options. They were not
properly repaired in 8.7.1.
Completely delete the Bcc: header if and only if there are other
valid recipient headers (To:, Cc: or Apparently-To:, the
last being a historic botch, of course). If Bcc: is the
only recipient header in the message, its value is tossed,
but the header name is kept. The old behavior (always keep
the header name and toss the value) allowed primary recipients
to see that a Bcc: went to _someone_.
Include queue id on ``Authentication-Warning: <host>: <user> set
sender to <address> using -f'' syslog messages. Suggested
by Kari Hurtta.
If a sequence or switch map lookup entry gets a tempfail but then
continues on to another map type, but the name is not found,
return a temporary failure from the sequence or switch map.
For example, if hosts search ``dns files'' and DNS fails
with a tempfail, the hosts map will go on and search files,
but if it fails the whole thing should be a tempfail, not
a permanent (host unknown) failure, even though that is the
failure in the hosts.files map. This error caused hard
bounces when it should have requeued.
Aliases to files such as /users/bar/foo/inbox, with /users/bar/foo
owned by bar mode 700 and inbox being set-user-ID bar stopped
working properly due to excessive paranoia. Pointed out by
John Hawkinson of Panix.
An SMTP RCPT command referencing a host that gave a nameserver
timeout would return a 451 command (8.6 accepted it and
queued it locally). Revert to the 8.6 behavior in order
to simplify queue management for clustered systems. Suggested
by Gregory Neil Shapiro of WPI. The same problem could break
MH, which assumes that the SMTP session will succeed (tsk, tsk
-- mail gets lost!); this was pointed out by Stuart Pook of
Infobiogen.
Fix possible buffer overflow in munchstring(). This was not a security
problem because you couldn't specify any argument to this
without first giving up root privileges, but it is still a
good idea to avoid future problems. Problem noted by John
Hawkinson and Sam Hartman of MIT.
``452 Out of disk space for temp file'' messages weren't being
printed. Fix from David Perlin of Nanosoft.
Don't advertise the ESMTP DSN extension if the SendMimeErrors option
is not set, since this is required to get the actual DSNs
created. Problem pointed out by John Gardiner Myers of CMU.
Log permission problems that cause .forward and :include: files to
be untrusted or ignored on log level 12 and higher. Suggested
by Randy Martin of Clemson University.
Allow user ids in U= clauses of M lines to have hyphens and
underscores.
Fix overcounting of recipients -- only happened when sending to an
alias. Pointed out by Mark Andrews of SGI and Jack Woolley
of Systems and Computer Technology Corporation.
If a message is sent to an address that fails, the error message that
is returned could show some extraneous "success" information
included even if the user did not request success notification,
which was confusing. Pointed out by Allan Johannesen of WPI.
Config files that had no AliasFile definition were defaulting to
using /etc/aliases; this caused problems with nullclient
configurations. Change it back to the 8.6 semantics of
having no local alias file unless it is declared. Problem
noted by Charles Karney of Princeton University.
Fix compile problem if NOTUNIX is defined. Pointed out by Bryan
Costales of ICSI.
Map lookups of class "userdb" maps were always case sensitive; they
should be controlled by the -f flag like other maps. Pointed
out by Bjart Kvarme <bjart.kvarme@usit.uio.no>.
Fix problem that caused some addresses to be passed through ruleset 5
even when they were tagged as "sticky" by prefixing the
address with an "@". Patch from Thomas Dwyer III of Michigan
Technological University.
When converting a message to Quoted-Printable, prevent any lines with
dots alone on a line by themselves. This is because of the
preponderance of broken mailers that still get this wrong.
Code contributed by Per Hedeland of Ericsson.
Fix F{macro}/file construct -- it previously did nothing. Pointed
out by Bjart Kvarme of USIT/UiO (Norway).
Announce whether a cached connection is SMTP or ESMTP (in -v mode).
Requested by Allan Johannesen.
Delete check for text format of alias files -- it should be legal
to have the database format of the alias files without the
text version. Problem pointed out by Joe Rhett of Navigist,
Inc.
If "Ot" was specified with no value, the TZ variable was not properly
imported from the environment. Pointed out by Frank Crawford
<frank@ansto.gov.au>.
Some architectures core dumped on "program" maps that didn't have
extra arguments. Patch from Booker C. Bense of Stanford
University.
Queue run processes would re-spawn daemons when given a SIGHUP; only
the parent should do this. Fix from Brian Coan of the
Association for Progressive Communications.
If MinQueueAge was set and a message was considered but not run
during a queue run and the Timeout.queuereturn interval was
reached, a "timed out" error message would be returned that
didn't include the failed address (and claimed to be a warning
even though it was fatal). The fix is to not return such
messages until they are actually tried, i.e., in the next
MinQueueAge interval. Problem noted by Rein Tollevik of
SINTEF RUNIT, Oslo.
Add HES_GETMAILHOST compile flag to support MIT Hesiod distributions
that have the hes_getmailhost() routine. DEC Hesiod
distributions do not have this routine. Based on a patch
from Betty Lee of Stanford University.
Extensive cleanups to map open code to handle a locking race condition
in ndbm, hash, and btree format database files on some (most
non-4.4-BSD based) OS architectures. This should solve the
occasional "user unknown" problem during alias rebuilds that
has plagued me for quite some time. Based on a patch from
Thomas Dwyer III of Michigan Technological University.
PORTABILITY FIXES:
Solaris: Change location of newaliases and mailq from
/usr/ucb to /usr/bin to match Sun settings. From

DomainOS: Makefile.DomainOS doesn't require -ldbm. From
Don Lewis of Silicon Systems.
HP-UX 10: rename Makefile.HP-UX.10 => Makefile.HP-UX.10.x
so that the makesendmail script will find it. Pointed
out by Richard Allen of the University of Iceland.
Also, use -Aa -D_HPUX_SOURCE instead of -Ae, which
isn't supported on all compilers.
UXPDS: compilation fixes from Diego R. Lopez.
CONFIG: FAX mailer wasn't setting .FAX as a pseudo-domain unless
you also had a FAX_RELAY. From Thomas.Tornblom@Hax.SE.
CONFIG: Minor glitch in S21 -- attachment of local domain name
didn't have trailing dot. From Jim Hickstein of Teradyne.
CONFIG: Fix best_mx_is_local feature to allow nested addresses such as
user%host@thishost. From Claude Scarpelli of Infobiogen
(France).
CONFIG: OSTYPE(hpux10) failed to define the location of the help file.
Pointed out by Hannu Martikka of Nokia Telecommunications.
CONFIG: Diagnose some inappropriate ordering in configuration files,
such as FEATURE(smrsh) listed after MAILER(local). Based on
a bug report submitted by Paul Hoffman of Proper Publishing.
CONFIG: Make OSTYPE files consistently not override settings that
have already been set. Previously it worked differently
for different files.
CONFIG: Change relay mailer to do masquerading like 8.6 did. My take
is that this is wrong, but the change was causing problems
for some people. From Per Hedeland of Ericsson.
CONTRIB: bitdomain.c patch from John Gardiner Myers <jgm+@CMU.EDU>;
portability changes for Posix environments (no functional
changes).
8.7.1/8.7.1 1995/10/01
Old macros that have become options (SmtpGreetingMessage,
OperatorChars, and UnixFromLine) didn't allow backslash
escapes in the options, where they previously had. Bug
pointed out by John Hawkinson of MIT.
Fix strange case of an executable called by a program map that
returns a value but also a non-zero exit status; this
would give contradictory results in the higher level; in
particular, the default clause in the map lookup would be
ignored. Change to ignore the value if the program returns
non-zero exit status. From Tom Moore of AT&T GIS.
Shorten parameters passed to syslog() in some contexts to avoid a
bug in many vendors' implementations of that routine. Although
this isn't really a bug in sendmail per se, and my solution
has to assume that syslog() has at least a 1K buffer size
internally (I know some vendors have shortened this
dramatically -- they're on their own), sendmail is a popular
target. Also, limit the size of %s arguments in sprintf.
These both have possible security implications. Solutions
suggested by Casper Dik of Sun's Network Security Group
(Holland), Mark Seiden, and others.
Fix a problem that might cause a non-standard -B (body type)
parameter to be passed to the next server with undefined
results. This could have security implications.
If a filesystem was at > 100% utilization, the freediskspace()
routine incorrectly returned an error rather than zero.
Problem noted by G. Paul Ziemba of Alantec.
Change MX sort order so that local hostnames (those in $=w) always
sort first within a given preference. This forces the bestmx
map to always return the local host first, if it is included
in the list of highest priority MX records. From K. Robert
Elz.
Avoid some possible null pointer dereferences. Fixes from Randy
Martin <WOLF@CLEMSON.EDU>
When sendmail starts up on systems that have no fully qualified
domain name (FQDN) anywhere in the first matching host map
(e.g., /etc/hosts if the hosts service searches "files dns"),
sendmail would sleep to try to find a FQDN, which it really
really needs. This has been changed to fall through to the
next map type if it can't find a FQDN -- i.e., if the hosts
file doesn't have a FQDN, it will try dns even though the
short name was found in /etc/hosts. This is probably a crock,
but many people have hosts files without FQDNs. Remember:
domain names are your friends.
Log a high-priority message if you can't find your FQDN during startup.
Suggested by Simon Barnes of Schlumberger Limited.
When using Hesiod, initialize it early to improve error reporting.
Patch from Don Lewis of Silicon Systems, Inc.
Apparently at least some versions of Linux have a 90 !minute! TCP
connection timeout in the kernel. Add a new "connect" timeout
to limit this time. Defaults to zero (use whatever the
kernel provides). Based on code contributed by J.R. Oldroyd
of TerraNet.
Under some circumstances, a failed message would not be properly
removed from the queue, causing tons of bogus error messages.
(This fix eliminates the problematic EF_KEEPQUEUE flag.)
Problem noted by Allan E Johannesen and Gregory Neil Shapiro
of WPI.
PORTABILITY FIXES:
On IRIX 5.x, there was an inconsistency in the setting
of sendmail.st location. Change the Makefile to
install it in /var/sendmail.st to match the OSTYPE
file and SGI standards. From Andre
<andre@curry.zfe.siemens.de>.
Support for Fujitsu/ICL UXP/DS (For the DS/90 Series)
from Diego R. Lopez <drlopez@cica.es>.
Linux compilation patches from J.R. Oldroyd of TerraNet, Inc.
LUNA 2 Mach patches from Motonori Nakamura.
SunOS Makefile was including -ldbm, which is for the old
dbm library. The ndbm library is part of libc.
CONFIG: avoid bouncing ``user@host.'' (note trailing dot) with
``local configuration error'' in nullclient configuration.
Patch from Gregory Neil Shapiro of WPI.
CONFIG: don't allow an alias file in nullclient configurations --
since all addresses are relayed, they give errors during
rebuild. Suggested by Per Hedeland of Ericsson.
CONFIG: local mailer on Solaris 2 should always get a -f flag because
otherwise the F=S causes the From_ line to imply that root is
the sender. Problem pointed out by Claude Scarpelli of
Infobiogen (France).

Fix a problem that could cause sendmail to run out of file
descriptors due to a trashed data structure after a
vfork. Fix from Brian Coan of the Institute for
Global Communications.
Change the VRFY response if you have disabled VRFY -- some
people seemed to think that it was too rude.
Avoid reference to uninitialized file descriptor if HASFLOCK
was not defined. This was used "safely" in the sense
that it only did a stat, but it would have set the
map modification time improperly. Problem pointed out
by Roy Mongiovi of Georgia Tech.
Clean up the Subject: line on warning messages and return
receipts so that they don't say "Returned mail:"; this
can be confusing.
Move ruleset entry/exit debugging from 21.2 to 21.1 -- this is
useful enough to make it worthwhile printing on "-d".
Avoid logging alias statistics every time you read the alias
file on systems with no database method compiled in.
If you have a name with a trailing dot, and you try looking it
up using gethostbyname without the dot (for /etc/hosts
compatibility), be sure to turn off RES_DEFNAMES and
RES_DNSRCH to avoid finding the wrong name accidentally.
Problem noted by Charles Amos of the University of
Maryland.
Don't do timeouts in collect if you are not running SMTP.
There is nothing that says you can't have a long
running program piped into sendmail (possibly via
/bin/mail, which just execs sendmail). Problem reported
by Don "Truck" Lewis of Silicon Systems.
Try gethostbyname() even if the DNS lookup fails iff option I
is not set. This allows you to have hosts listed in
NIS or /etc/hosts that are not known to DNS. It's normally
a bad idea, but can be useful on firewall machines. This
should really be broken out on a separate flag, I suppose.
Avoid compile warnings against BIND 4.9.3, which uses function
prototypes. From Don Lewis of Silicon Systems.
Avoid possible incorrect diagnosis of DNS-related errors caused
by things like attempts to resolve uucp names using
$[ ... $] -- the fix is to clear h_errno at appropriate
times. From Kyle Jones of UUNET.
SECURITY: avoid denial-of-service attacks possible by destroying
the alias database file by setting resource limits low.
This involves adding two new compile-time options:
HASSETRLIMIT (indicating that setrlimit(2) support is
available) and HASULIMIT (indicating that ulimit(2) support
is available -- the Release 3 form is used). The former
is assumed on BSD-based systems, the latter on System
V-based systems. Attack noted by Phil Brandenberger of
Swarthmore University.
New syntaxes in test (-bt) mode:
``.Dmvalue'' will define macro "m" to "value".
``.Ccvalue'' will add "value" to class "c".
``=Sruleset'' will dump the contents of the indicated
ruleset.
``=M'' will display the known mailers.
``-ddebug-spec'' is equivalent to the command-line
-d debug flag.
``$m'' will print the value of macro $m.
``$=c'' will print the contents of class $=c.
``/mx host'' returns the MX records for ``host''.
``/parse address'' will parse address, returning the value of
crackaddr (essentially, the comment information)
and the parsed address.
``/try mailer address'' will rewrite address into the form
it will have when presented to the indicated mailer.
``/tryflags flags'' will set flags used by parsing. The
flags can be `H' for header or `E' for envelope,
and `S' for sender or `R' for recipient. These
can be combined, so `HR' sets flags for header
recipients.
``/canon hostname'' will try to canonify hostname and
return the result.
``/map mapname key'' will look up `key' in the indicated
`mapname' and return the result.
Somewhat better handling of UNIX-domain socket addresses -- it
should show the pathname rather than hex bytes.
Restore ``-ba'' mode -- this reads a file from stdin and parses
the header for envelope sender information and uses
CR-LF as message terminators. It was thought to be
obsolete (used only for Arpanet NCP protocols), but it
turns out that the UK ``Grey Book'' protocols require
that functionality.
Fix a fix in previous release -- if gethostname and gethostbyname
return a name without dots, and if an attempt to canonify
that name fails, wait one minute and try again. This can
result in an extra 60 second delay on startup if your system
hostname (as returned by hostname(1)) has no dot and no names
listed in /etc/hosts or your NIS map have a dot.
Check for proper domain name on HELO and EHLO commands per
RFC 1123 section 5.2.5. Problem noted by Thomas Dwyer III
of Michigan Technological University.
Relax chownsafe rules slightly -- old version said that if you
can't tell if _POSIX_CHOWN_RESTRICTED is set (that is,
if fpathconf returned EINVAL or ENOSYS), assume that
chown is not safe. The new version falls back to whether
you are on a BSD system or not. This is important for
SunOS, which apparently always returns one of those
error codes. This impacts whether you can mail to files
or not.
Syntax errors such as unbalanced parentheses in the configuration
file could be omitted if you had "Oem" prior to the
syntax error in the config file. Change to always print
the error message. It was especially weird because it
would cause a "warning" message to be sent to the Postmaster
for every message sent (but with no transcript). Problem
noted by Gregory Paris of Motorola.
Rewrite collect and putbody to handle full 8-bit data, including
zero bytes. These changes are internally extensive, but
should have minimal impact on external function.
Allow full words for option names -- if the option letter is
(apparently) a space, then take the word following -- e.g.,
O MatchGECOS=TRUE
The full list of old and new names is as follows:

The old macros that passed information into sendmail have
been changed to options; those correspondences are:
$e SmtpGreetingMessage
$l UnixFromLine
$o OperatorChars
$q (deleted -- not necessary)
To avoid possible problems with an older sendmail,
configuration level 6 is accepted by this version of
sendmail; any config file using the new names should
specify "V6" in the configuration.
Change address parsing to properly note that a phrase before a
colon and a trailing semicolon are essentially the same
as text outside of angle brackets (i.e., sendmail should
treat them as comments). This is to handle the
``group name: addr1, addr2, ..., addrN;'' syntax (it will
assume that ``group name:'' is a comment on the first
address and the ``;'' is a comment on the last address).
This requires config file support to get right. It does
understand that :: is NOT this syntax, and can be turned
off completely by setting the ColonOkInAddresses option.
Level 6 config files added with new mailer flags:
A Addresses are aliasable.
i Do udb rewriting on envelope as well as header
sender lines. Applies to the from address mailer
flags rather than the recipient mailer flags.
j Do udb rewriting on header recipient addresses.
Applies to the sender mailer flags rather than the
recipient mailer flags.
k Disable check for loops when doing HELO command.
o Always run as the mail recipient, even on local
delivery.
w Check for an /etc/passwd entry for this user.
5 Pass addresses through ruleset 5.
: Check for :include: on this address.
| Check for |program on this address.
/ Check for /file on this address.
@ Look up sender header addresses in the user
database. Applies to the mailer flags for the
mailer corresponding to the envelope sender
address, rather than to recipient mailer flags.
Pre-level 6 configuration files set A, w, 5, :, |, /, and @
on the "local" mailer, the o flag on the "prog" and "*file*"
mailers, and the ColonOkInAddresses option.
Eight-to-seven bit MIME conversions. This borrows ideas from
John Beck of Hewlett-Packard, who generously contributed
their implementation to me, which I then didn't use (see
mime.c for an explanation of why). This adds the
EightBitMode option (a.k.a. `8') and an F=8 mailer flag
to control handling of 8-bit data. These have to cope with
two types of 8-bit data: unlabelled 8-bit data (that is,
8-bit data that is entered without declaring it as 8-bit
MIME -- technically this is illegal according to the
specs) and labelled 8-bit data (that is, it was declared
as 8BITMIME in the ESMTP session or by using the
-B8BITMIME command line flag). If the F=8 mailer flag is
set then 8-bit data is sent to non-8BITMIME machines
instead of converting to 7 bit (essentially using
just-send-8 semantics). The values for EightBitMode are:
m convert unlabelled 8-bit input to 8BITMIME, and do
any necessary conversion of 8BITMIME to 7BIT
(essentially, the full MIME option).
p pass unlabelled 8-bit input, but convert labelled
8BITMIME input to 7BIT as required (default).
s strict adherence: reject unlabelled 8-bit input,
convert 8BITMIME to 7BIT as required. The F=8
flag is ignored.
Unlabelled 8-bit data is rejected in mode `s' regardless of
the setting of F=8.
Add new internal class 'n', which is the set of MIME Content-Types
which can not be 8 to 7 bit encoded because of other
considerations. Types "multipart/*" and "message/*" are
never directly encoded (although their components can be).
Add new internal class 's', which is the set of subtypes of the
MIME message/* content type that can be treated as though
they are an RFC822 message. It is predefined to have
"rfc822". Suggested By Kari Hurtta.
Add new internal class 'e'. This is the set of MIME
Content-Transfer-Encodings that can be converted to
a seven bit format (Quoted-Printable or Base64). It is
preinitialized to contain "7bit", "8bit", and "binary".
Add C=charset mailer parameter and the the DefaultCharSet option (no
short name) to set the default character set to use in the
Content-Type: header when doing encoding of an 8-bit message
which isn't marked as MIME into MIME format. If the C=
parameter is set on the Envelope From address, use that as
the default encoding; else use the DefaultCharSet option.
If neither is set, it defaults to "unknown-8bit" as
suggested by RFC 1428 section 3.
Allow ``U=user:group'' field in mailer definition to set a default
user and group that a mailer will be executed as. This
overrides the 'u' and 'g' options, and if the `F=S' flag is
also set, it is the uid/gid that will always be used (that
is, the controlling address is ignored). The values may be
numeric or symbolic; if only a symbolic user is given (no
group) that user's default group in the passwd file is used
as the group. Based on code donated by Chip Rosenthal of
Unicom.
Allow `u' option to also accept user:group as a value, in the same
fashion as the U= mailer option.
Add the symbolic time zone name in the Arpanet format dates (as
a comment). This adds a new compile-time configuration
flag: TZ_TYPE can be set to TZ_TM_NAME (use the value
of (struct tm *)->tm_name), TZ_TM_ZONE (use the value
of (struct tm *)->tm_zone), TZ_TZNAME (use extern char
*tzname[(struct tm *)->tm_isdst]), TZ_TIMEZONE (use
timezone()), or TZ_NONE (don't include the comment). Code
from Chip Rosenthal.
The "Timeout" option (formerly "r") is extended to allow suboptions.
For example,
O Timeout.helo = 2m
There are also two new suboptions "queuereturn" and
"queuewarn"; these subsume the old T option. Thus, to
set them both the preferred new syntax is
O Timeout.queuereturn = 5d
O Timeout.queuewarn = 4h
Sort queue by host name instead of by message priority if the
QueueSortOrder option (no short name) is set is set to
``host''. This makes better use of the connection cache,
but may delay more ``interactive'' messages behind large
backlogs under some circumstances. This is probably a
good option if you have high speed links or don't do lots
of ``batch'' messages, but less good if you are using
something like PPP on a 14.4 modem. Based on code
contributed by Roy Mongiovi of Georgia Tech (my main
contribution was to make it configurable).
Save i-number of df file in qf file to simplify rebuilding of queue
after disastrous disk crash. Suggested by Kyle Jones of
UUNET; closely based on code from KJS DECWRL code written
by Paul Vixie. NOTA BENE: The qf files produced by 8.7
are NOT back compatible with 8.6 -- that is, you can convert
from 8.6 to 8.7, but not the other direction.
Add ``F=d'' mailer flag to disable all use of angle brackets in
route-addrs in envelopes; this is because in some cases
they can be sent to the shell, which interprets them as
I/O redirection.
Don't include error file (option E) with return-receipts; this
can be confusing.
Don't send "Warning: cannot send" messages to owner-* or
*-request addresses. Suggested by Christophe Wolfhugel
of the Institut Pasteur, Paris.
Allow -O command line flag to set long form options.
Add "MinQueueAge" option to set the minimum time between attempts
to run the queue. For example, if the queue interval
(-q value) is five minutes, but the minimum queue age
is fifteen minutes, jobs won't be tried more often than
once every fifteen minutes. This can be used to give
you more responsiveness if your delivery mode is set to
queue-only.
Allow "fileopen" timeout (default: 60 seconds) for opening
:include: and .forward files.
Add "-k", "-v", and "-z" flags to map definitions; these set the
key field name, the value field name, and the field
delimiter. The field delimiter can be a single character
or the sequence "\t" or "\n" for tab or newline.
These are for use by NIS+ and similar access methods.
Change maps to always strip quotes before lookups; the -q flag
turns off this behavior. Suggested by Motonori Nakamura.
Add "nisplus" map class. Takes -k and -v flags to choose the
key and value field names respectively. Code donated by
Sun Microsystems.
Add "hesiod" map class. The "file name" is used as the
"HesiodNameType" parameter to hes_resolve(3). Returns the
first value found for the match. Code donated by Scott
Hutton of Indiana University.
Add "netinfo" (NeXT NetInfo) map class. Maps can have a -k flag to
specify the name of the property that is searched as the
key and a -v flag to specify the name of the property that
is returned as the value (defaults to "members"). The
default map is "/aliases". Some code based on code
contributed by Robert La Ferla of Hot Software.
Add "text" map class. This does slow, linear searches through
text files. The -z flag specifies a column delimiter
(defaults to any sequence of white space), the -k flag
sets the key column number, and the -v flag sets the
value column number. Lines beginning with `#' are treated
as comments.
Add "program" map class to execute arbitrary programs. The search
key is presented as the last argument; the output is one
line read from the programs standard output. Exit statuses
are from sysexits.h.
Add "sequence" map class -- searches maps in sequence until it
finds a match. For example, the declarations:
Kmap1 ...
Kmap2 ...
Kmapseq sequence map1 map2
defines a map "mapseq" that first searches map1; if the
value is found it is returned immediately, otherwise
map2 is searched and the value returned.
Add "switch" map class. This is much like "sequence" except that
the ordering is fetched from an external file, usually
the system service switch. The parameter is the name of
the service to switch on, and the maps that it will use
are the name of the switch map followed by ".service_type".
For example, if the declaration of the map is
Ksample switch hosts
and the system service switch specifies that hosts are
looked up using dns and nis in that order, then this is
equivalent to
Ksample sequence sample.dns sample.nis
The subordinate maps (sample.*) must already be defined.
Add "user" map class -- looks up users using getpwnam. Takes a
"-v field" flag on the definition that tells what passwd
entry to return -- legal values are name, passwd, uid, gid,
gecos, dir, and shell. Generally expected to be used with
the -m (matchonly) flag.
Add "bestmx" map class -- returns the best MX value for the host
listed as the value. If there are several "best" MX records
for this host, one will be chosen at random.
Add "userdb" map class -- looks up entries in the user database.
The "file name" is actually the tag that will be used,
typically "mailname". If there are multiple entries
matching the name, the one chosen is undefined.
Add multiple queue timeouts (both return and warning). These are
set by the Precedence: or Priority: header fields to one of
three values. If a Priority: is set and has value "normal",
"urgent", or "non-urgent" the corresponding timeouts are
used. If no priority is set, the Precedence: is consulted;
if negative, non-urgent timeouts are used; if greater than
zero, urgent timeouts are used. Otherwise, normal timeouts
are used. The timeouts are set by setting the six timeouts
queue{warn,return}.{urgent,normal,non-urgent}.
Fix problem when a mail address is resolved to a $#error mailer
with a temporary failure indication; it works in SMTP,
but when delivering locally the mail is silently discarded.
This patch, from Kyle Jones of UUNET, bounces it instead
of queueing it (queueing is very hard).
When using /etc/hosts or NIS-style lookups, don't assume that
the first name in the list is the best one -- instead,
search for the first one with a dot. For example, if
an /etc/hosts entry reads
128.32.149.68 mammoth mammoth.CS.Berkeley.EDU
this change will use the second name as the canonical
machine name instead of the initial, unqualified name.
Change dequote map to replace spaces in quoted text with a value
indicated by the -s flag on the dequote map definition.
For example, ``Mdequote dequote -s_'' will change
"Foo Bar" into an unquoted Foo_Bar instead of leaving it
quoted (because of the space character). Suggested by Dan
Oscarsson for use in X.400 addresses.
Implement long macro names as ${name}; long class names can
be similarly referenced as $={name} and $~{name}.
Definitions are (e.g.) ``D{name}value''. Names that have
a leading lower case letter or punctuation characters are
reserved for internal use by sendmail; i.e., config files
should use names that begin with a capital letter. Based
on code contributed by Dan Oscarsson.
Fix core dump if getgrgid returns a null group list (as opposed
to an empty group list, that is, a pointer to a list
with no members). Fix from Andrew Chang of Sun Microsystems.
Fix possible core dump if malloc fails -- if the malloc in xalloc
failed, it called syserr which called newstr which called
xalloc.... The newstr is now avoided for "panic" messages.
Reported by Stuart Kemp of James Cook University.
Improve connection cache timeouts; previously, they were not even
checked if you were delivering to anything other than an
IPC-connected host, so a series of (say) local mail
deliveries could cause cached connections to be open
much longer than the specified timeout.
If an incoming message exceeds the maximum message size, stop
writing the incoming bytes to the queue data file, since
this can fill your mqueue partition -- this is a possible
denial-of-service attack.
Don't reject all numeric local user names unless HESIOD is
defined. It turns out that Posix allows all-numeric
user names. Fix from Tony Sanders of BSDI.
Add service switch support. If the local OS has a service
switch (e.g., /etc/nsswitch.conf on Solaris or /etc/svc.conf
on DEC systems) that will be used; otherwise, it falls back
to using a local mechanism based on the ServiceSwitchFile
option (default: /etc/service.switch). For example, if the
service switch lists "files" and "nis" for the aliases
service, that will be the default lookup order. the "files"
("local" on DEC) service type expands to any alias files
you listed in the configuration file, even if they aren't
actually file lookups.
Option I (NameServerOptions) no longer sets the "UseNameServer"
variable which tells whether or not DNS should be considered
canonical. This is now determined based on whether or not
"dns" is in the service list for "hosts".
Add preliminary support for the ESMTP "DSN" extension (Delivery
Status Notifications). DSN notifications override
Return-Receipt-To: headers, which are bogus anyhow --
support for them has been removed.
Add T=mts-name-type/address-type/diagnostic-type keyletter to mailer
definitions to define the types used in DSN returns for
MTA names, addresses, and diagnostics respectively.
Extend heuristic to force running in ESMTP mode to look for the
five-character string "ESMTP" anywhere in the 220 greeting
message (not just the second line). This is to provide
better compatibility with other ESMTP servers.
Print sequence number of job when running the queue so you can
easily see how much progress you have made. Suggested
by Peter Wemm of DIALix.
Map newlines to spaces in logged message-ids; some versions of
syslog truncate the rest of the line after newlines.
Suggested by Fletcher Mattox of U. Texas.
Move up forking for job runs so that if a message is split into
multiple envelopes you don't get "fork storms" -- this
also improves the connection cache utilization.
Accept "<<>>", "<<<>>>", and so forth as equivalent to "<>" for
the purposes of refusing to send error returns. Suggested
by Motonori Nakamura of Ritsumeikan University.
Relax rules on when a file can be written when referenced from
the aliases file: use the default uid/gid instead of the
real uid/gid. This allows you to create a file owned by
and writable only by the default uid/gid that will work
all the time (without having the set-user-ID bit set). Change
suggested by Shau-Ping Lo and Andrew Cheng of Sun
Microsystems.
Add "DialDelay" option (no short name) to provide an "extra"
delay for dial on demand systems. If this is non-zero
and a connect fails, sendmail will wait this long and
then try again. If it takes longer than the kernel
timeout interval to establish the connection, this
option can give the network software time to establish
the link. The default units are seconds.
Move logging of sender information to be as early as possible;
previously, it could be delayed a while for SMTP mail
sent to aliases. Suggested by Brad Knowles of the
Defense Information Systems Agency.
Call res_init() before setting RES_DEBUG; this is required by
BIND 4.9.3, or so I'm told. From Douglas Anderson of
the National Computer Security Center.
Add xdelay= field in logs -- this is a transaction delay, telling
you how long it took to deliver to this address on the
last try. It is intended to be used for sorting mailing
lists to favor "quick" addresses. Provided for use by
the mailprio scripts (see below).
If a map cannot be opened, and that map is non-optional, and
an address requires that map for resolution, queue the
map instead of bouncing it. This involves creating a
pseudo-class of maps called "bogus-map" -- if a required
map cannot be opened, the class is changed to bogus-map;
all queries against bogus-map return "tempfail". The
bogus-map class is not directly accessible. A sample
implementation was donated by Jem Taylor of Glasgow
University Computing Service.
Fix a possible core dump when mailing to a program that talks
SMTP on its standard input. Fix from Keith Moore of
the University of Kentucky.
Make it possible to resolve filenames to $#local $: @ /filename;
previously, the "@" would cause it to not be recognized
as a file. Problem noted by Brian Hill of U.C. Davis.
Accept a -1 signal to re-exec the daemon. This only works if
argv[0] is a full path to sendmail.
Fix bug in "addr=..." field in O option on little-endian machines
-- the network number wasn't being converted to network
byte order. Patch from Kurt Lidl of Pix Technologies
Corporation.
Pre-initialize the resolver early on; this is to avoid a bug with
BIND 4.9.3 that can cause the _res.retry field to get
reset to zero, causing all name server lookups to time
out. Fix from Matt Day of Artisoft.
Restore T line (trusted users) in config file -- but instead of
locking out the -f flag, they just tell whether or not
an X-Authentication-Warning: will be added. This really
just creates new entries in class 't', so "Ft/file/name"
can be used to read trusted user names from a file.
Trusted users are also allowed to execute programs even
if they have a shell that isn't in /etc/shells.
Improve NEWDB alias file rebuilding so it will create them
properly if they do not already exist. This had been
a MAYBENEXTRELEASE feature in 8.6.9.
Check for @:@ entry in NIS maps before starting up to avoid
(but not prevent, sigh) race conditions. This ought to
be handled properly in ypserv, but isn't. Suggested by
Michael Beirne of Motorola.
Refuse connections if there isn't enough space on the filesystem
holding the queue. Contributed by Robert Dana of Wolf
Communications.
Skip checking for directory permissions in the path to a file
when checking for file permissions iff setreuid()
succeeded -- it is unnecessary in that case. This avoids
significant performance problems when looking for .forward
files. Based on a suggestion by Win Bent of USC.
Allow symbolic ruleset names. Syntax can be "Sname" to get an
arbitrary ruleset number assigned or "Sname = integer"
to assign a specific ruleset number. Reference is
$>name_or_number. Names can be composed of alphas, digits,
underscore, or hyphen (first character must be non-numeric).
Allow -o flag on AliasFile lines to make the alias file optional.
From Bryan Costales of ICSI.
Add NoRecipientAction option to handle the case where there is
no legal recipient header in the message. It can take
on values:
None Leave the message as is. The
message will be passed on even
though it is in technically
illegal syntax.
Add-To Add a To: header with any
recipients that it can find from
the envelope. This risks exposing
Bcc: recipients.
Add-Apparently-To Add an Apparently-To: header. This
has almost no redeeming social value,
and is provided only for back
compatibility.
Add-To-Undisclosed Add a header reading
To: undisclosed-recipients:;
which will have the effect of
making the message legal without
exposing Bcc: recipients.
Add-Bcc To add an empty Bcc: header.
There is a chance that mailers down
the line will delete this header,
which could cause exposure of Bcc:
recipients.
The default is NoRecipientAction=None.
Truncate (rather than delete) Bcc: lines in the header. This
should prevent later sendmails (at least, those that don't
themselves delete Bcc:) from considering this message to
be non-conforming -- although it does imply that non-blind
recipients can see that a Bcc: was sent, albeit not to whom.
Add SafeFileEnvironment option. If declared, files named as delivery
targets must be regular files in addition to the regular
checks. Also, if the option is non-null then it is used as
the name of a directory that is used as a chroot(2)
environment for the delivery; the file names listed in an
alias or forward should include the name of this root.
For example, if you run with
O SafeFileEnvironment=/arch
then aliases should reference "/arch/rest/of/path". If a
value is given, sendmail also won't try to save to
/usr/tmp/dead.letter (instead it just leaves the job in the
queue as Qfxxxxxx). Inspired by *Hobbit*'s sendmail patch kit.
Support -A flag for alias files; this will comma concatenate like
entries. For example, given the aliases:
list: member1
list: member2
and an alias file declared as:
OAhash:-A /etc/aliases
the final alias inserted will be "list: member1,member2";
without -A you will get an error on the second and subsequent
alias for "list". Contributed by Bryan Costales of ICSI.
Line-buffer transcript file. Suggested by Liudvikas Bukys.
Fix a problem that could cause very long addresses to core dump in
some special circumstances. Problem pointed out by Allan
Johannesen.
(Internal change.) Change interface to expand() (macro expansion)
to be simpler and more consistent.
Delete check for funny qf file names. This didn't really give
any extra security and caused some people some problems.
(If you -really- want this, define PICKY_QF_NAME_CHECK
at compile time.) Suggested by Kyle Jones of UUNET.
(Internal change.) Change EF_NORETURN to EF_NO_BODY_RETN and
merge with DSN code; this is simpler and more consistent.
This may affect some people who have written their own
checkcompat() routine.
(Internal change.) Eliminate `D' line in qf file. The df file
is now assumed to be the same name as the qf file (with
the `q' changed to a `d', of course).
Avoid forking for delivery if all recipient mailers are marked as
"expensive" -- this can be a major cost on some systems.
Essentially, this forces sendmail into "queue only" mode
if all it is going to do is queue anyway.
Avoid sending a null message in some rather unusual circumstances
(specifically, the RCPT command returns a temporary
failure but the connection is lost before the DATA
command). Fix from Scott Hammond of Secure Computing
Corporation.
Change makesendmail to use a somewhat more rational naming scheme:
Makefiles and obj directories are named $os.$rel.$arch,
where $os is the operating system (e.g., SunOS), $rel is
the release number (e.g., 5.3), and $arch is the machine
architecture (e.g., sun4). Any of these can be omitted,
and anything after the first dot in a release number can
be replaced with "x" (e.g., SunOS.4.x.sun4). The previous
version used $os.$arch.$rel and was rather less general.
Change makesendmail to do a "make depend" in the target directory
when it is being created. This involves adding an empty
"depend:" entry in most Makefiles.
Ignore IDENT return value if the OSTYPE field returns "OTHER",
as indicated by RFC 1413. Pointed out by Kari Hurtta
of the Finnish Meteorological Institute.
Fix problem that could cause multiple responses to DATA command
on header syntax errors (e.g., lines beginning with colons).
Problem noted by Jens Thomassen of the University of Oslo.
Don't let null bytes in headers cause truncation of the rest of
the header.
Log Authentication-Warning:s. Suggested by Motonori Nakamura.
Increase timeouts on message data puts to allow time for receivers
to canonify addresses in headers on the fly. This is still
a rather ugly heuristic. From Motonori Nakamura.
Add "HasWildcardMX" suboption to ResolverOptions; if set, MX
records are not used when canonifying names, and when MX
lookups are done for addressing they must be fully
qualified. This is useful if you have a wildcard MX record,
although it may cause other problems. In general, don't use
wildcard MX records. Patch from Motonori Nakamura.
Eliminate default two-line SMTP greeting message. Instead of
adding an extra "ESMTP spoken here" line, the word "ESMTP"
is added between the first and second word of the first
line of the greeting message (i.e., immediately after the
host name). This eliminates the need for the BROKEN_SMTP_PEERS
compile flag. Old sendmails won't see the ESMTP, but that's
acceptable because SIZE was the only useful extension that
old sendmails understand.
Avoid gethostbyname calls on UNIX domain sockets during SIGUSR1
invoked state dumps. From Masaharu Onishi.
Allow on-line comments in .forward and :include: files; they are
introduced by the string "<LWSP>#@#<LWSP>", where <LWSP>
is a space or a tab. This is intended for native
representation of non-ASCII sets such as Japanese, where
existing encodings would be unreadable or would lose
data -- for example,
<motonori@cs.ritsumei.ac.jp> NAKAMURA Motonori
(romanized/less information)
<motonori@cs.ritsumei.ac.jp> =?ISO-2022-JP?B?GyRCQ2ZCPBsoQg==?=
=?ISO-2022-JP?B?GyRCQUdFNRsoQg==?=
(with MIME encoding, not human readable)
<motonori@cs.ritsumei.ac.jp> #@# ^[$BCfB<^[(B ^[$BAGE5^[(B
(native encoding with ISO-2022-JP)
The last form is human readable in the Japanese environment.
Based on a fix from (surprise!) Motonori Nakamura.
Don't make SMTP error returns on MAIL FROM: line be "sticky" for all
messages to that host; these are most frequently associated
with addresses rather than the host, with the exception of
421 (service shutting down). The effect was to cause queues
to sometimes take an excessive time to flush. Reported by
Robert Sargent of Southern Geographics Technologies and
Eric Prestemon of American University.
Add Nice=N mailer option to set the niceness at which a mailer will
run. This is actually a relative niceness (that is, an
increment on the background value).
Log queue runs that are skipped due to high loads. They are logged
at LOG_INFO priority iff the log level is > 8. Contributed
by Bruce Nagel of Data General.
Allow the error mailer to accept a DSN-style error status code
instead of an sysexits status code in the host part.
Anything with a dot will be interpreted as a DSN-style code.
Add new mailer flag: F=3 will tell translations to Quoted-Printable
to encode characters that might be munged by an EBCDIC system
in addition to the set required by RFC 1521. The additional
characters are !, ", #, $, @, [, \, ], ^, `, {, |, }, and ~.
(Think of "IBM 360" as the mnemonic for this flag.)
Change check for mailing to files to look for a pathname of [FILE]
rather than looking for the mailer named *file*. The mapping
of leading slashes still goes to the *file* mailer. This
allows you to implement the *file* mailer as a separate
program, for example, to insert a Content-Length: header
or do special security policy. However, note that the usual
initial checking for the file permissions is still done, and
the program in question needs to be very careful about how
it does the file write to avoid security problems.
Be able to read ~root/.forward even if the path isn't accessible to
regular users. This is disrecommended because sendmail
sometimes does not run as root (e.g., when an unsafe option
is specified on the command line), but should otherwise be
safe because .forward files must be owned by the user for
whom mail is being forwarded, and cannot be a symbolic link.
Suggested by Forrest Aldrich of Wang Laboratories.
Add new "HostsFile" option that is the pathname to the /etc/hosts
file. This is used for canonifying hostnames when the
service type is "files".
Implement programs on F (read class from file) line. The syntax is
Fc|/path/to/program to read the output from the program
into class "c".
Probe the network interfaces to find alternate names for this
host. Requires the SIOCGIFCONF ioctl call. Code
contributed by SunSoft.
Add "E" configuration line to set or propagate environment
variables into children. "E<envar>" will propagate
the named variable from the environment when sendmail
was invoked into any children it calls; "E<envar>=<value>"
sets the named variable to the indicated value. Any
variables not explicitly named will not be in the child
environment. However, sendmail still forces an
"AGENT=sendmail" environment variable, in part to enforce
at least one environment variable, since many programs and
libraries die horribly if this is not guaranteed.
Change heuristic for rebuilding both NEWDB and NDBM versions of
alias databases -- new algorithm looks for the substring
"/yp/" in the file name. This is more portable and involves
less overhead. Suggested by Motonori Nakamura.
Dynamically allocate the queue work list so that you don't lose
jobs in large queue runs. The old QUEUESIZE compile parameter
is replaced by QUEUESEGSIZE (the unit of allocation, which
should not need to be changed) and the MaxQueueRunSize option,
which is the absolute maximum number of jobs that will ever
be handled in a single queue run. Based on code contributed
by Brian Coan of the Institute for Global Communications.
Log message when a message is dropped because it exceeds the maximum
message size. Suggested by Leo Bicknell of Virginia Tech.
Allow trusted users (those on a T line or in $=t) to use -bs without
an X-Authentication-Warning: added. Suggested by Mark Thomas
of Mark G. Thomas Consulting.
Announce state of compile flags on -d0.1 (-d0.10 throws in the
OS-dependent defines). The old semantic of -d0.1 to not
run the daemon in background has been moved to -d99.100,
and the old 52.5 flag (to avoid disconnect() from closing
all output files) has been moved to 52.100. This makes
things more consistent (flags below .100 don't change
semantics) and separates out the backgrounding so that
it doesn't happen automatically on other unrelated debugging
flags.
If -t is used but no addresses are found in the header, give an
error message rather than just doing nothing. Fix from
Motonori Nakamura.
On systems (like SunOS) where the effective gid is not necessarily
included in the group list returned by getgroups(), the
`restrictmailq' option could sometimes cause an authorized
user to not be able to use `mailq'. Fix from Charles Hannum
of MIT.
Allow symbolic service names for [IPC] mailers. Suggested by
Gerry Magennis of Logica International.
Add DontExpandCnames option to prevent $[ ... $] from expanding CNAMEs
when running DNS. For example, if the name FTP.Foo.ORG is
a CNAME for Cruft.Foo.ORG, then when sitting on a machine in
the Foo.ORG domain a lookup of "FTP" returns "Cruft.Foo.ORG"
if this option is not set, or "FTP.Foo.ORG" if it is set.
This is technically illegal under RFC 822 and 1123, but the
IETF is moving toward legalizing it. Note that turning on
this option is not sufficient to guarantee that a downstream
neighbor won't rewrite the address for you.
Add "-m" flag to makesendmail script -- this tells you what object
directory and Makefile it will use, but doesn't actually do
the make.
Do some additional checking on the contents of the qf file to try
to detect attacks against the qf file. In particular,
abort on any line beginning "From ", and add an "end of
file" line -- any data after that line is prohibited.
Always use /etc/sendmail.cf, regardless of the arbitrary vendor
choices. This can be overridden in the Makefile by using
either -DUSE_VENDOR_CF_PATH to get the vendor location
(to the extent that we know it) or by defining
_PATH_SENDMAILCF (which is a "hard override"). This allows
sendmail 8 to have more consistent installation instructions.
Allow macros on `K' line in config file. Suggested by Andrew Chang
of Sun Microsystems.
Improved symbol table hash function from Eric Wassenaar. This one
is at least 50% faster.
Fix problem that didn't notice that timeout on file open was a
transient error. Fix from Larry Parmelee of Cornell
University.
Allow comments (lines beginning with a `#') in files read for
classes. Suggested by Motonori Nakamura.
Make SIGINT (usually ^C) in test mode return to the prompt instead
of dropping out entirely. This makes testing some of the
name server lookups easier to deal with when there are
hung servers. From Motonori Nakamura.
Add new ${opMode} macro that is set to the current operation mode
(e.g., `s' for -bs, `t' for -bt, etc.). Suggested by
Claude Marinier <MARINIER@emp.ewd.dreo.dnd.ca>.
Add new delivery mode (Odd) that defers all map lookups to queue runs.
Kind of like queue-only mode (Odq) except it tries to avoid
any external service requests; for dial-on-demand hosts that
want to minimize DNS lookups when mail is being queued. For
this to work you will also have to make sure that gethostbyname
of your local host name does not do a DNS lookup.
Improved handling of "out of space" conditions from John Myers of
Carnegie Mellon.
Improved security for mailing to files on systems that have fchmod(2)
support.
Improve "cannot send message for N days" message -- now says "could
not send for past N days". Suggested by Tom Moore of AT&T
Global Information Solutions.
Less misleading Subject: line on messages sent to postmaster only.
From Motonori Nakamura.
Avoid duplicate error messages on bad command line flags. From
Motonori Nakamura.
Better error message for case where ruleset 0 falls off the end
or otherwise does not resolve to a canonical triple.
Fix a problem that could cause multiple bounce messages if a bad
address was sent along with a good address to an SMTP
site where that SMTP site returned a 4yz code in response
to the final dot of the data. Problem reported by David
James of British Telecom.
Add "volatile" declarations so that gcc -O2 will work. Patches
from Alexander Dupuy of System Management ARTS.
Delete duplicates in MX lists -- believe it or not, there are sites
that list the same host twice in an MX list. This deletion
only works on adjacent preferences, so an MX list that
had A=5, B=10, A=15 would leave both As, but one that had
A=5, A=10, B=15 would reduce to A, B. This is intentional,
just in case there is something weird I haven't thought of.
Suggested by Barry Shein of Software Tool & Die.
SECURITY: .forward files cannot be symbolic links. If they are,
a bad guy can read your private files.
PORTABILITY FIXES:
Solaris 2 from Rob McMahon <cudcv@csv.warwick.ac.uk>.
System V Release 4 from Motonori Nakamura of Ritsumeikan
University. This expands the disk size
checking to include all (?) SVR4 configurations.
System V Release 4 from Kimmo Suominen -- initgroups(3)
and setrlimit(2) are both available.
System V Release 4 from sob@sculley.ffg.com -- some versions
apparently "have EX_OK defined in other headerfiles."
Linux Makefile typo.
Linux getusershell(3) is broken in Slackware 2.0 --
from Andrew Pam of Xanadu Australia.
More Linux tweaking from John Kennedy of California State
University, Chico.
Cray changes from Eric Wassenaar: ``On Cray, shorts,
ints, and longs are all 64 bits, and all structs
are multiples of 64 bits. This means that the
sizeof operator returns only multiples of 8.
This requires adaptation of code that really
deals with 32 bit or 16 bit fields, such as IP
addresses or nameserver fields.''
DG/UX 5.4.3 from Mark T. Robinson <mtr@ornl.gov>. To
get the old behavior, use -DDGUX_5_4_2.
DG/UX hack: add _FORCE_MAIL_LOCAL_=yes environment
variable to fix bogus /bin/mail behavior.
Tandem NonStop-UX from Rick McCarty <mccarty@mpd.tandem.com>.
This also cleans up some System V Release 4 compile
problems.
Solaris 2: sendmail.cw file should be in /etc/mail to
match all the other configuration files. Fix
from Glenn Barry of Emory University.
Solaris 2.3: compile problem in conf.c. Fix from Alain
Nissen of the University of Liege, Belgium.
Ultrix: freespace calculation was incorrect. Fix from
Takashi Kizu of Osaka University.
SVR4: running in background gets a SIGTTOU because the
emulation code doesn't realize that "getpeername"
doesn't require reading the file. Fix from Peter
Wemm of DIALix.
Solaris 2.3: due to an apparent bug in the socket emulation
library, sockets can get into a "wedged" state where
they just return EPROTO; closing and re-opening the
socket clears the problem. Fix from Bob Manson
of Ohio State University.
Hitachi 3050R & 3050RX running HI-UX/WE2: portability
fixes from Akihiro Hashimoto ("Hash") of Chiba
University.
AIX changes to allow setproctitle to work from Rainer Schöpf
of Zentrum für Datenverarbeitung der Universität
Mainz.
AIX changes for load average from Ed Ravin of NASA/Goddard.
SCO Unix from Chip Rosenthal of Unicom (code was using the
wrong statfs call).
ANSI C fixes from Adam Glass (NetBSD project).
Stardent Titan/ANSI C fixes from Kate Hedstrom of Rutgers
University.
DG-UX fixes from Bruce Nagel of Data General.
IRIX64 updates from Mark Levinson of the University of
Rochester Medical Center.
Altos System V (``the first UNIX/XENIX merge the Altos
did for their Series 1000 & Series 2000 line;
their merged code was licensed back to AT&T and
Microsoft and became System V release 3.2'') from
Tim Rice <timr@crl.com>.
OSF/1 running on Intel Paragon from Jeff A. Earickson
<jeff@ssd.intel.com> of Intel Scalable Systems
Division.
Amdahl UTS System V 2.1.5 (SVr3-based) from Janet Jackson

IRIX 5.2 and 5.3 from Kari E. Hurtta.
FreeBSD 2.0 from Mike Hickey of Federal Data Corporation.
Sony NEWS-OS 4.2.1R and 6.0.3 from Motonori Nakamura.
Omron LUNA unios-b, mach from Motonori Nakamura.
NEC EWS-UX/V 4.2 from Motonori Nakamura.
NeXT 2.1 from Bryan Costales.
AUX patch thanks to Mike Erwin of Apple Computer.
HP-UX 10.0 from John Beck of Hewlett-Packard.
Ultrix: allow -DBROKEN_RES_SEARCH=0 if you are using a
non-DEC resolver. Suggested by Allan Johannesen.
UnixWare 2.0 fixes from Petr Lampa of the Technical
University of Brno (Czech Republic).
KSR OS 1.2.2 support from Todd Miller of the University
of Colorado.
UX4800 support from Kazuhisa Shimizu of NEC.
MAKEMAP: allow -d flag to allow insertion of duplicate aliases
in type ``btree'' maps. The semantics of this are undefined
for regular maps, but it can be useful for the user database.
MAKEMAP: lock database file while rebuilding to avoid sendmail
lookups while the rebuild is going on. There is a race
condition between the open(... O_TRUNC ...) and the lock
on the file, but it should be quite small.
SMRSH: sendmail restricted shell added to the release. This can
be used as an alternative to /bin/sh for the "prog" mailer,
giving the local administrator more control over what
programs can be run from sendmail.
MAIL.LOCAL: add this local mailer to the tape. It is not really
part of the release proper, and isn't fully supported; in
particular, it does not run on System V based systems and
never will.
CONTRIB: a patch to rmail.c from Bill Gianopoulos of Raytheon
to allow rmail to compile on systems that don't have
function prototypes and systems that don't have snprintf.
CONTRIB: add the "mailprio" scripts that will help you sort mailing
lists by transaction delay times so that addresses that
respond quickly get sent first. This is to prevent very
sluggish servers from delaying other peoples' mail.
Contributed by Tony Sanders of BSDI.
CONTRIB: add the "bsdi.mc" file as contributed by Tony Sanders
of BSDI. This has a lot of comments to help people out.
CONFIG: Don't have .mc files include(../m4/cf.m4) -- instead,
put this on the m4 command line. On GNU m4 (which
supports the __file__ primitive) you can run m4 in an
arbitrary directory -- use either:
m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf
or
m4 -I${CFDIR} m4/cf.m4 config.mc > config.cf
On other versions of m4 that don't support __file__, you
can use:
m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 ...
(Note the trailing slash on the _CF_DIR_ definition.)
Old versions of m4 will default to _CF_DIR_=.. for back
compatibility.
CONFIG: fix mail from <> so it will properly convert to
MAILER-DAEMON on local addresses.
CONFIG: fix code that was supposed to catch colons in host
names. Problem noted by John Gardiner Myers of CMU.
CONFIG: allow use of SMTP_MAILER_MAX in nullclient configuration.
From Paul Riddle of the University of Maryland, Baltimore
County.
CONFIG: Catch and reject "." as a host address.
CONFIG: Generalize domaintable to look up all domains, not
just unqualified ones.
CONFIG: Delete OLD_SENDMAIL support -- as near as I can tell, it
was never used and didn't work anyway.
CONFIG: Set flags A, w, 5, :, /, |, and @ on the "local" mailer
and d on all mailers in the UUCP class.
CONFIG: Allow "user+detail" to be aliased specially: it will first
look for an alias for "user+detail", then for "user+*", and
finally for "user". This is intended for forwarding mail
for system aliases such as root and postmaster to a
centralized hub.
CONFIG: add confEIGHT_BIT_HANDLING to set option 8 (see above).
CONFIG: add smtp8 mailer; this has the F=8 (just-send-8) flag set.
The F=8 flag is also set on the "relay" mailer, since
this is expected to be another sendmail.
CONFIG: avoid qualifying all UUCP addresses sent via SMTP with
the name of the UUCP_RELAY -- in some cases, this is the
wrong value (e.g., when we have local UUCP connections),
and this can create unreplyable addresses. From Chip
Rosenthal of Unicom.
CONFIG: add confRECEIVED_HEADER to change the format of the
Received: header inserted into all messages. Suggested by
Gary Mills of the University of Manitoba.
CONFIG: Make "notsticky" the default; use FEATURE(stickyhost)
to get the old behavior. I did this upon observing
that almost everyone needed this feature, and that the
concept I was trying to make happen didn't work with
some user agents anyway. FEATURE(notsticky) still works,
but it is a no-op.
CONFIG: Add LUSER_RELAY -- the host to which unrecognized user
names are sent, rather than immediately diagnosing them
as User Unknown.
CONFIG: Add SMTP_MAILER_ARGS, ESMTP_MAILER_ARGS, SMTP8_MAILER_ARGS,
and RELAY_MAILER_ARGS to set the arguments for the
indicated mailers. All default to "IPC $h". Patch from
Larry Parmelee of Cornell University.
CONFIG: pop mailer needs F=n flag to avoid "annoying side effects
on the client side" and F=P to get an appropriate
return-path. From Kimmo Suominen.
CONFIG: add FEATURE(local_procmail) to use the procmail program
as the local mailer. For addresses of the form "user+detail"
the "detail" part is passed to procmail via the -a flag.
Contributed by Kimmo Suominen.
CONFIG: add MAILER(procmail) to add an interface to procmail for
use from mailertables. This lets you execute arbitrary
procmail scripts. Contributed by Kimmo Suominen.
CONFIG: add T= fields (MTS type) to local, smtp, and uucp mailers.
CONFIG: add OSTYPE(ptx2) for DYNIX/ptx 2.x from Sequent. From
Paul Southworth of CICNet Systems Support.
CONFIG: use -a$g as default to UUCP mailers, instead of -a$f.
This causes the null return path to be rewritten as
MAILER-DAEMON; otherwise UUCP gets horribly confused.
From Michael Hohmuth of Technische Universitat Dresden.
CONFIG: Add FEATURE(bestmx_is_local) to cause any hosts that
list us as the best possible MX record to be treated as
though they were local (essentially, assume that they
are included in $=w). This can cause additional DNS
traffic, but is easier to administer if this fits your
local model. It does not work reliably if there are
multiple hosts that share the best MX preference.
Code contributed by John Oleynick of Rutgers.
CONFIG: Add FEATURE(smrsh) to use smrsh (the SendMail Restricted
SHell) instead of /bin/sh as the program used for delivery
to programs. If an argument is included, it is used as
the path to smrsh; otherwise, /usr/local/etc/smrsh is
assumed.
CONFIG: Add LOCAL_MAILER_MAX and PROCMAILER_MAILER_MAX to limit the
size of messages to the local and procmail mailers
respectively. Contributed by Brad Knowles of the Defense
Information Systems Agency.
CONFIG: Handle leading ``phrase:'' and trailing ``;'' as comments
(just like text outside of angle brackets) in order to
properly deal with ``group: addr1, ... addrN;'' syntax.
CONFIG: Require OSTYPE macro (the defaults really don't apply to
any real systems any more) and tweak the DOMAIN macro
so that it is less likely that users will accidentally use
the Berkeley defaults. Also, create some generic files
that really can be used in the real world.
CONFIG: Add new configuration macros to set character sets for
messages _arriving from_ various mailers: LOCAL_MAILER_CHARSET,
SMTP_MAILER_CHARSET, and UUCP_MAILER_CHARSET.
CONFIG: Change UUCP_MAX_SIZE to UUCP_MAILER_MAX for consistency.
The old name will still be accepted for a while at least.
CONFIG: Implement DECNET_RELAY as spec for host to which DECNET
mail (.DECNET pseudo-domain or node::user) will be sent.
As with all relays, it can be ``mailer:hostname''. Suggested
by Scott Hutton.
CONFIG: Add MAILER(mail11) to get DECnet support. Code contributed
by Barb Dijker of Labyrinth Computer Services.
CONFIG: change confCHECK_ALIASES to default to False -- it has poor
performance for large alias files, and this confused many
people.
CONFIG: Add confCF_VERSION to append local information to the
configuration version number displayed during SMTP startup.
CONFIG: fix some.newsgroup.usenet@local.host syntax (previously it
would only work when locally addressed. Fix from
Edvard Tuinder of Cistron Internet Services.
CONFIG: use ${opMode} to avoid error on .REDIRECT addresses if option
"n" (CheckAliases) is set when rebuilding alias database.
Based on code contributed by Claude Marinier.
CONFIG: Allow mailertable to have values of the form
``error:code message''. The ``code'' is a status code
derived from the sysexits codes -- e.g., NOHOST or UNAVAILABLE.
Contributed by David James <dwj@agw.bt.co.uk>.
CONFIG: add MASQUERADE_DOMAIN(domain list) to extend the list of
sender domains that will be replaced with the masquerade name.
These domains will not be treated as local, but if mail passes
through with sender addresses in those domains they will be
replaced by the masquerade name. These can also be specified
in a file using MASQUERADE_DOMAIN_FILE(filename).
CONFIG: add FEATURE(masquerade_envelope) to masquerade the envelope
as well as the header. Substantial improvements to this
code were contributed by Per Hedeland.
CONFIG: add MAILER(phquery) to define a new "ph" mailer; this can be
accessed from a mailertable to do CCSO ph lookups. Contributed
by Kimmo Suominen.
CONFIG: add MAILER(cyrus) to define a new Cyrus mailer; this can be
used to define cyrus and cyrusbb mailers (for IMAP support).
Contributed by John Gardiner Myers of Carnegie Mellon.
CONFIG: add confUUCP_MAILER to select default mailer to use for
UUCP addressing. Suggested by Tom Moore of AT&T GIS.

8.6.13/8.6.12 1996/01/25
SECURITY: In some cases it was still possible for an attacker to
insert newlines into a queue file, thus allowing access to
any user (except root).
CONFIG: no changes -- it is not a bug that the configuration
version number is unchanged.
8.6.12/8.6.12 1995/03/28
Fix to IDENT code (it was getting the size of the reply buffer
too small, so nothing was ever accepted). Fix from several
people, including Allan Johannesen, Shane Castle of the
Boulder County Information Services, and Jeff Smith of
Warwick University (all arrived within a few hours of
each other!).
Fix a problem that could cause large jobs to run out of
file descriptors on systems that use vfork() rather
than fork().
8.6.11/8.6.11 1995/03/08
The ``possible attack'' message would be logged more often
than necessary if you are using Pine as a user agent.
The wrong host would be reported in the ``possible attack''
message when attempted from IDENT.
In some cases the syslog buffer could be overflowed when
reporting the ``possible attack'' message. This can
cause denial of service attacks. Truncate the message
to 80 characters to prevent this problem.
When reading the IDENT response a loop is needed around the
read from the network to ensure that you don't get
partial lines.
Password entries without any shell listed (that is, a null
shell) wouldn't match as "ok". Problem noted by
Rob McMahon.
When running BIND 4.9.x a problem could occur because the
_res.options field is initialized differently than it
was historically -- this requires that sendmail call
res_init before it tweaks any bits.
Fix an incompatibility in openxscript() between the file open mode
and the stdio mode passed to fdopen. This caused UnixWare
2.0 to have conniptions. Fix from Martin Sohnius of
Novell Labs Europe.
Fix problem with static linking of local getopt routine when
using GNU's ld command. Fix from John Kennedy of
Cal State Chico.
It was possible to turn off privacy flags. Problem noted by
*Hobbit*.
Be more paranoid about writing files. Suggestions by *Hobbit*
and Liudvikas Bukys.
MAKEMAP: fixes for 64 bit machines (DEC Alphas in particular)
from Spider Boardman.
CONFIG: No changes (version number only, to keep it in sync
with the binaries).
8.6.10/8.6.10 1995/02/10
SECURITY: Diagnose bogus values to some command line flags that
could allow trash to get into headers and qf files.
Validate the name of the user returned by the IDENT protocol.
Some systems that really dislike IDENT send intentionally
bogus information. Problem pointed out by Michael Bushnell
of the Free Software Foundation. Has some security
implications.
Fix a problem causing error messages about DNS problems when
the host name contained a percent sign to act oddly
because it was passed as a printf-style format string.
In some cases this could cause core dumps.
Avoid possible buffer overrun in returntosender() if error
message is quite long. From Fletcher Mattox of the
University of Texas.
Fix a problem that would silently drop "too many hops" error
messages if and only if you were sending to an alias.
From Jon Giltner of the University of Colorado and
Dan Harton of Oak Ridge National Laboratory.
Fix a bug that caused core dumps on some systems if -d11.2 was
set and e->e_message was null. Fix from Bruce Nagel of
Data General.
Fix problem that can still cause df files to be left around
after "hop count exceeded" messages. Fix from Andrew
Chang and Shau-Ping Lo of SunSoft.
Fix a problem that can cause buffer overflows on very long
user names (as might occur if you piped to a program
with a lot of arguments).
Avoid returning an error and re-queueing if the host signature
is null; this can occur on addresses like ``user@.''.
Problem noted by Wesley Craig and the University of
Michigan.
Avoid possible calls to malloc(0) if MCI caching is turned
off. Bug fix from Pierre David of the Laboratoire
Parallelisme, Reseaux, Systemes et Modelisation (PRiSM),
Universite de Versailles - St Quentin, and Jacky
Thibault.
Make a local copy of the line being sent via senttolist() -- in
some cases, buffers could get trashed by map lookups
causing it to do unexpected things. This also simplifies
some of the map code.
CONFIG: No changes (version number only, to keep it in sync
with the binaries).
8.6.9/8.6.9 1994/04/19
Do all mail delivery completely disconnected from any terminal.
This provides consistency with daemon delivery and
may have some security implications.
Make sure that malloc doesn't get called with zero size,
since that fails on some systems. Reported by Ed
Hill of the University of Iowa.
Fix multi-line values for $e (SMTP greeting message). Reported
by Mike O'Connor of Ford Motor Company.
Avoid syserr if no NIS domain name is defined, but the map it
is trying to open is optional. From Win Bent of USC.
Changes for picky compilers from Ed Gould of Digital Equipment.
Hesiod support for UDB from Todd Miller of the University of
Colorado. Use "hesiod" as the service name in the U
option.
Fix a problem that failed to set the "authentic" host name (that
is, the one derived from the socket info) if you called
sendmail -bs from inetd. Based on code contributed by
Todd Miller (this problem was also reported by Guy Helmer
of Dakota State University). This also fixes a related
problem reported by Liudvikas Bukys of the University of
Rochester.
Parameterize "nroff -h" in all the Makefiles so people with
variant versions can use them easily. Suggested by
Peter Collinson of Hillside Systems.
SMTP "MAIL" commands with multiple ESMTP parameters required two
spaces between parameters instead of one. Reported by
Valdis Kletnieks of Virginia Tech.
Reduce the number of system calls during message collection by
using global timeouts around the collect() loop. This
code was contributed by Eric Wassenaar.
If the initial hostname name gathering results in a name
without a dot (usually caused by NIS misconfiguration)
and BIND is compiled in, directly access DNS to get
the canonical name. This should make life easier for
Solaris systems. If it still can't be resolved, and
if the name server is listed as "required", try again
in 30 seconds. If that also fails, exit immediately to
avoid bogus "config error: mail loops back to myself"
messages.
Improve the "MAIL DELETED BECAUSE OF LACK OF DISK SPACE" error
message to explain how much space was available and
sound a bit less threatening. Suggested by Stan Janet
of the National Institute of Standards and Technology.
If mail is delivered to an alias that has an owner, deliver any
requested return-receipt immediately, and strip the
Return-Receipt-To: header from the subsequent message.
This prevents a certain class of denial of service
attack, arguably gives more reasonable semantics, and
moves things more towards what will probably become a
network standard. Suggested by Christopher Davis of
Kapor Enterprises.
Add a "noreceipts" privacy flag to turn off all return receipts
without recompiling.
Avoid printing ESMTP parameters as part of the error message
if there are errors during parsing. This change is
purely cosmetic.
Avoid sending out error messages during the collect phase of
SMTP; there is an MVS mailer from UCLA that gets
confused by this. Of course, I think it's their bug....
Check for the $j macro getting undefined, losing a dot, or getting
lost from $=w in the daemon before accepting a connection;
if it is, it dumps state, prints a LOG_ALERT message,
and drops core for debugging. This is an attempt to
track down a bug that I thought was long since gone.
If you see this, please forward the log fragment to
sendmail@sendmail.ORG.
Change OLD_NEWDB from a #ifdef to a #if so it can be turned off
with -DOLD_NEWDB=0 on the command line. From Christophe
Wolfhugel.
Instead of trying to truncate the listen queue for the server
SMTP port when the load average is too high, just close
the port completely and reopen it later as needed.
This ensures that the other end gets a quick "connection
refused" response, and that the connection can be
recovered later. In particular, some socket emulations
seem to get confused if you tweak the listen queue
size around and can never start listening to connections
again. The down side is that someone could start up
another daemon process in the interim, so you could
have multiple daemons all not listening to connections;
this could in turn cause the sendmail.pid file to be
incorrect. A better approach might be to accept the
connection and give a 421 code, but that could break
other mailers in mysterious ways and have paging behavior
implications.
Fix a glitch in TCP-level debugging that caused flag 16.101 to
set debugging on the wrong socket. From Eric Wassenaar.
When creating a df* temporary file, be sure you truncate any
existing data in the file -- otherwise system crashes
and the like could result in extra data being sent.
DOC: Replace the CHANGES-R5-R8 readme file with a paper in the
doc directory. This includes some additional
information.
CONFIG: change UUCP rules to never add $U! or $k! on the front
of recipient envelope addresses. This should have been
handled by the $&h trick, but broke if people were
mixing domainized and UUCP addresses. They should
probably have converted all the way over to uucp-uudom
instead of uucp-{new,old}, but the failure mode was to
loop the mail, which was bad news.
Portability fixes:
Newer BSDI systems (several people).
Older BSDI systems from Christophe Wolfhugel.
Intergraph CLIX, from Paul Southworth of CICNet.
UnixWare, from Evan Champion.
NetBSD from Adam Glass.
Solaris from Quentin Campbell of the University of
Newcastle upon Tyne.
IRIX from Dean Cookson and Bill Driscoll of Mitre
Corporation.
NCR 3000 from Kevin Darcy of Chrysler Financial Corporation.

Jonathan Kamens of OpenVision Technologies.
HP-UX from Tor Lillqvist.

8.6.8/8.6.6 1994/03/21
SECURITY: it was possible to read any file as root using the
E (error message) option. Reported by Richard Jones;
fixed by Michael Corrigan and Christophe Wolfhugel.
8.6.7/8.6.6 1994/03/14
SECURITY: it was possible to get root access by using weird
values to the -d flag. Thanks to Alain Durand of
INRIA for forwarding me the notice from the bugtraq
list.
8.6.6/8.6.6 1994/03/13
SECURITY: the ability to give files away on System V-based
systems proved dangerous -- don't run as the owner
of a :include: file on a system that allows giveaways.
Unfortunately, this also applies to determining a
valid shell.
IMPORTANT: Previous versions weren't expiring old connections
in the connection cache for a long time under some
circumstances. This could result in resource exhaustion,
both at your end and at the other end. This checks the
connections for timeouts much more frequently. From
Doug Anderson of NCSC.
Fix a glitch that snuck in that caused programs to be run as
the sender instead of the recipient if the mail was
from a local user to another local user. From
Motonori Nakamura of Kyoto University.
Fix "wildcard" on /etc/shells matching -- instead of looking
for "*", look for "/SENDMAIL/ANY/SHELL/". From
Bryan Costales of ICSI.
Change the method used to declare the "statfs" availability;
instead of HASSTATFS and/or HASUSTAT with a ton of
tweaking in conf.c, there is a single #define called
SFS_TYPE which takes on one of six values (SFS_NONE
for no statfs availability, SFS_USTAT for the ustat(2)
syscall, SFS_4ARGS for a four argument statfs(2) call,
and SFS_VFS, SFS_MOUNT, or SFS_STATFS for a two argument
statfs(2) call with the declarations in <sys/vfs.h>,
<sys/mount.h>, or <sys/statfs.h> respectively).
Fix glitch in NetInfo support that could return garbage if
there was no "/locations/sendmail" property. From
David Meyer of the University of Virginia.
Change HASFLOCK from defined/not-defined to a 0/1 definition
to allow Linux to turn it off even though it is a
BSD-like system.
Allow setting of "ident" timeout to zero to turn off the ident
protocol entirely.
Make 7-bit stripping local to a connection (instead of to a
mailer); this allows you to specify that SMTP is a
7-bit channel, but revert to 8-bit should it advertise
that it supports 8BITMIME. You still have to specify
mailer flag 7 to get this stripping at all.
Improve makesendmail script so it handles more cases automatically.
Tighten up restrictions on taking ownership of :include: files
to avoid problems on systems that allow you to give away
files.
Fix a problem that made it impossible to rebuild the alias
file if it was on a read-only file system. From
Harry Edmon of the University of Washington.
Improve MX randomization function. From John Gardiner Myers
of CMU.
Fix a minor glitch causing a bogus message to be printed (used
%s instead of %d in a printf string for the line number)
when a bad queue file was read. From Harry Edmon.
Allow $s to remain NULL on locally generated mail. I'm not
sure this is necessary, but a lot of people have complained
about it, and there is a legitimate question as to whether
"localhost" is legal as an 822-style domain.
Fix a problem with very short line lengths (mailer L= flag) in
headers. This causes a leading space to be added onto
continuation lines (including in the body!), and also
tries to wrap headers containing addresses (From:, To:,
etc) intelligently at the shorter line lengths. Problem
Reported by Lars-Johan Liman of SUNET Operations Center.
Log the real user name when logging syserrs, since these can have
security implications. Suggested by several people.
Fix address logging of cached connections -- it used to always
log the numeric address as zero. This is a somewhat
bogus implementation in that it does an extra system
call, but it should be an inexpensive one. Fix from
Motonori Nakamura.
Tighten up handling of short syslog buffers even more -- there
were cases where the outgoing relay= name was too long
to share a line with delay= and mailer= logging.
Limit the overhead on split envelopes to one open file descriptor
per envelope -- previously the overhead was three
descriptors. This was in response to a problem reported
by P{r (Pell) Emanuelsson.
Fixes to better handle the case of unexpected connection closes;
this redirects the output to the transcript so the info
is not lost. From Eric Wassenaar.
Fix potential string overrun if you macro evaluate a string that
has a naked $ at the end. Problem noted by James Matheson
<jmrm@eng.cam.ac.uk>.
Make default error number on $#error messages 553 (``Requested
action not taken: mailbox name not allowed'') instead of
501 (``Syntax error in parameters or arguments'') to
avoid bogus "protocol error" messages.
Strip off any existing trailing dot on names during $[ ... $]
lookup. This prevents it from ending up with two dots
on the end of dot terminated names. From Wesley Craig
of the University of Michigan and Bryan Costales of ICSI.
Clean up file class reading so that the debugging information is
more informative. It hadn't been using setclass, so you
didn't see the class items being added.
Avoid core dump if you are running a version of sendmail where
NIS is compiled in, and you specify an NIS map, but
NIS is not running. Fix from John Oleynick of
Rutgers.
Diagnose bizarre case where res_search returns a failure value,
but sets h_errno to a success value.
Make sure that "too many hops" messages are considered important
enough to send an error to the Postmaster (that is, the
address specified in the P option). This fix should
help problems that cause the df file to be left around
sometimes -- unfortunately, I can't seem to reproduce
the problem myself.
Avoid core dump (null pointer reference) on EXPN command; this
only occurred if your log level was set to 10 or higher
and the target account was an alias or had a .forward file.
Problem noted by Janne Himanka.
Avoid "denial of service" attacks by someone who is flooding your
SMTP port with bad commands by shutting the connection
after 25 bad commands are issued. From Kyle Jones of
UUNET.
Fix core dump on error messages with very long "to" buffers;
fmtmsg overflows the message buffer. Fixed by trimming
the to address to 203 characters. Problem reported by
John Oleynick.
Fix configuration for HASFLOCK -- there were some spots where
a #ifndef was incorrectly #ifdef. Pointed out by
George Baltz of the University of Maryland.
Fix a typo in savemail() that could cause the error message To:
lists to be incorrect in some places. From Motonori
Nakamura.
Fix a glitch that can cause duplicate error messages on split
envelopes where an address on one of the lists has a
name server failure. Fix from Voradesh Yenbut of the
University of Washington.
Fix possible bogus pointer reference on ESMTP parameters that
don't have an ``=value'' part.
CNAME loops caused an error message to be generated, but also
re-queued the message. Changed to just re-queue the
message (it's really hard to just bounce it because
of the weird way the name server works in the presence
of CNAME loops). Problem noted by James M.R.Matheson
of Cambridge University.
Avoid giving ``warning: foo owned process doing -bs'' messages
if they use ``MAIL FROM:<foo>'' where foo is their true
user name. Suggested by Andreas Stolcke of ICSI.
Change the NAMED_BIND compile flag to be a 0/1 flag so you can
override it easily in the Makefile -- that is, you can
turn it off using -DNAMED_BIND=0.
If a gethostbyname(...) of an address with a trailing dot fails,
try it without the trailing dot. This is because if
you have a version of gethostbyname() that falls back
to NIS or the /etc/hosts file it will fail to find
perfectly reasonable names that just don't happen to
be dot terminated in the hosts file. You don't want to
strip the dot first though because we're trying to ensure
that country names that match one of your subdomains get
a chance.
PRALIASES: fix bogus output on non-null-terminated strings.
From Bill Gianopoulos of Raytheon.
CONFIG: Avoid rewriting anything that matches $w to be $j.
This was in code intended to only catch the self-literal
address (that is, [1.2.3.4], where 1.2.3.4 is your
IP address), but the code was broken. However, it will
still do this if $M is defined; this is necessary to
get client configurations to work (sigh). Note that this
means that $M overrides :mailname entries in the user
database! Problem noted by Paul Southworth.
CONFIG: Fix definition of Solaris help file location. From
Steve Cliffe <steve@gorgon.cs.uow.edu.au>.
CONFIG: Fix bug that broke news.group.USENET mappings.
CONFIG: Allow declaration of SMTP_MAILER_MAX, FAX_MAILER_MAX,
and USENET_MAILER_MAX to tweak the maximum message
size for various mailers.
CONFIG: Change definition of USENET_MAILER_ARGS to include argv[0]
instead of assuming that it is "inews" for consistency
with other mailers. From Michael Corrigan of UC San Diego.
CONFIG: When mail is forwarded to a LOCAL_RELAY or a MAIL_HUB,
qualify the address in the SMTP envelope as user@{relay|hub}
instead of user@$j. From Bill Wisner of The Well.
CONFIG: Fix route-addr syntax in nullrelay configuration set.
CONFIG: Don't turn off case mapping of user names in the local
mailer for IRIX. This was different than most every other
system.
CONFIG: Avoid infinite loops on certainly list:; syntaxes in
envelope. Noted by Thierry Besancon
<besancon@excalibur.ens.fr>.
CONFIG: Don't include -z by default on uux line -- most systems
don't want it set by default. Pointed out by Philippe
Michel of Thomson CSF.
CONFIG: Fix some bugs with mailertables -- for example, if your
host name was foo.bar.ray.com and you matched against
".ray.com", the old implementation bound %1 to "bar"
instead of "foo.bar". Also, allow "." in the mailertable
to match anything -- essentially, take over SMART_HOST.
This also moves matching of explicit local host names
before the mailertable so they don't have to be special
cased in the mailertable data. Reported by Bill
Gianopoulos of Raytheon; the fix for the %1 binding
problem was contributed by Nicholas Comanos of the
University of Sydney.
CONFIG: Don't include "root" in class $=L (users to deliver
locally, even if a hub or relay exists) by default.
This is because of the known bug where definition of
both a LOCAL_RELAY and a MAIL_HUB causes $=L to ignore
both and deliver into the local mailbox.
CONFIG: Move up bitdomain and uudomain handling so that they
are done before .UUCP class matching; uudomain was
reported as ineffective before. This also frees up
diversion 8 for future use. Problem reported by Kimmo
Suominen.
CONFIG: Don't try to convert dotted IP address (e.g., [1.2.3.4])
into host names. As pointed out by Jonathan Kamens,
these are often used because either the forward or reverse
mapping is broken; this translation makes it broken again.
DOC: Clarify $@ and $: in the Install & Op Guide. From Kimmo
Suominen.

8.6.5/8.6.5 1994/01/13
Security fix: /.forward could be owned by anyone (the test
to allow root to own any file was backwards). From
Bob Campbell at U.C. Berkeley.
Security fix: group ids were not completely set when programs
were invoked. This caused programs to have group
permissions they should not have had (usually group
daemon instead of their own group). In particular,
Perl scripts would refuse to run.
Security: check to make sure files that are written are not
symbolic links (at least under some circumstances).
Although this does not respond to a specific known
attack, it's just a good idea. Suggested by
Christian Wettergren.
Security fix: if a user had an NFS mounted home directory on
a system with a restricted shell listed in their
/etc/passwd entry, they could still execute any
program by putting that in their .forward file.
This fix prevents that by insisting that their shell
appear in /etc/shells before allowing a .forward to
execute a program or write a file. You can disable
this by putting "*" in /etc/shells. It also won't
permit world-writable :include: files to reference
programs or files (there's no way to disable this).
These behaviors are only one level deep -- for
example, it is legal for a world-writable :include:
file to reference an alias that writes a file, on
the assumption that the alias file is well controlled.
Security fix: root was not treated suspiciously enough when
looking into subdirectories. This would potentially
allow a cracker to examine files that were publicly
readable but in a non-publicly searchable directory.
Fix a problem that causes an error on QUIT on a cached
connection to create problems on the current job.
These are typically unrelated, so errors occur in
the wrong place.
Reset CurrentLA in sendall() -- this makes sendmail queue
runs more responsive to load average, and fixes a
problem that ignored the load average in locally
generated mail. From Eric Wassenaar.
Fix possible core dump on aliases with null LHS. From
John Orthoefer of BB&N.
Revert to using flock() whenever possible -- there are just
too many bugs in fcntl() locking, particularly over
NFS, that cause sendmail to fail in perverse ways.
Fix a bug that causes the connection cache to get confused
when sending error messages. This resulted in
"unexpected close" messages. It should fix itself
on the following queue run. Problem noted by
Liudvikas Bukys of the University of Rochester.
Include $k in $=k as documented in the Install & Op Guide.
This seems odd, but it was documented.... From
Michael Corrigan of UCSD.
Fix problem that caused :include:s from alias files to be
forced to be owned by root instead of daemon
(actually DefUid). From Tim Irvin.
Diagnose unrecognized I option values -- from Mortin Forssen
of the Chalmers University of Technology.
Make "error" mailer work consistently when there is no error
code associated with it -- previously it returned OK
even though there was a real problem. Now it assumes
EX_UNAVAILABLE.
Fix bug that caused the last header line of messages that had
no body and which were terminated with EOF instead of
"." to be discarded. Problem noted by Liudvikas Bukys.
Fix core dump on SMTP mail to programs that failed -- it tried
to go to a "next MX host" when none existed, causing
a core dump. From der Mouse at McGill University.
Change IDENTPROTO from a defined/not defined to a 0/1 switch;
this makes it easier to turn it off (using
-DIDENTPROTO=0 in the Makefile). From der Mouse.
Fix YP_MASTER_NAME store to use the unupdated result of
gethostname() (instead of myhostname(), which tries
to fully qualify the name) to be consistent with
SunOS. If your hostname is unqualified, this fixes
transfers to secondary servers. Bug noted by Keith
McMillan of Ameritech Services, Inc.
Fix Ultrix problem: gethostbyname() can return a very large
(> 500) h_length field, which causes the sockaddr
to be trashed. Use the size of the sockaddr instead.
Fix from Bob Manson of Ohio State.
Don't assume "-a." on host lookups if NAMED_BIND is not
defined -- this confuses gethostbyname on hosts
file lookups, which doesn't understand the trailing
dot convention.
Log SMTP server subprocesses that die with a signal instead
of from a clean exit.
If you don't have option "I" set, don't assume that a DNS
"host unknown" message is authoritative -- it
might still be found in /etc/hosts.
Fix a problem that would cause Deferred: messages to be sent
as the subject of an error message, even though the
actual cause of a message was more severe than that.
Problem noted by Chris Seabrook of OSSI.
Fix race condition in DBM alias file locking. From Kyle
Jones of UUNET.
Limit delivery syslog line length to avoid bugs in some
versions of syslog(3). This adds a new compile time
variable SYSLOG_BUFSIZE. From Jay Plett of Princeton
University, which is in turn derived from IDA.
Fix quotes inside of comments in addresses -- previously
it insisted that they be balanced, but the 822 spec
says that they should be ignored.
Dump open file state to syslog upon receiving SIGUSR1 (for
debugging). This also evaluates ruleset 89, if set
(with the null input), and logs the result. This
should be used sparingly, since the rewrite process
is not reentrant.
Change -qI, -qR, and -qS flags to be case-insensitive as
documented in the Bat Book.
If the mailer returned EX_IOERR or EX_OSERR, sendmail did not
return an error message and did not requeue the message.
Fix based on code from Roland Dirlewanger of
Reseau Regional Aquarel, Bordeaux, France.
Fix a problem that caused a seg fault if you got a 421 error
code during some parts of connection initialization.
I've only seen this when talking to buggy mailers on
the other end, but it shouldn't give a seg fault in
any case. From Amir Plivatsky.
Fix core dump caused by a ruleset call that returns null.
Fix from Bryan Costales of ICSI.
Full-Name: field was being ignored. Fix from Motonori Nakamura
of Kyoto University.
Fix a possible problem with very long input lines in setproctitle.
From P{r Emanuelsson.
Avoid putting "This is a warning message" out on return receipts.
Suggested by Douglas Anderson.
Detect loops caused by recursive ruleset calls. Suggested by
Bryan Costales.
Initialize non-alias maps during alias rebuilds -- they may be
needed for parsing. Problem noted by Douglas Anderson.
Log sender address even if no message was collected in SMTP
(e.g., if all RCPTs failed). Suggested by Motonori
Nakamura.
Don't reflect the owner-list contents into the envelope sender
address if the value contains ", :, /, or | (to avoid
illegal addresses appearing there).
Efficiency hack for toktype macro -- from Craig Partridge of
BB&N.
Clean up DNS error printing so that a host name is always
included.
Remember to set $i during queue runs. Reported by Stephen
Campbell of Dartmouth University.
If the environment variable HOSTALIASES is set, use it during
canonification as the name of a file with per-user host
translations so that headers are properly mapped. Reported
by Anne Bennett of Concordia University.
Avoid printing misleading error message if SMTP mailer (not
using [IPC]) should die on a core dump.
Avoid incorrect diagnosis of "file 1 closed" when it is caused
by the other end closing the connection. From
Dave Morrison of Oracle.
Improve several of the error messages printed by "mailq"
to include a host name or other useful information.
Add NetInfo preliminary support for NeXT systems. From Vince
DeMarco.
Fix a glitch that sometimes caused :include:s that pointed to
NFS filesystems that were down to give an "aliasing/
forwarding loop broken" message instead of queueing
the message for retry. Noted by William C Fenner of
the NRL Connection Machine Facility.
Fix a problem that could cause a core dump if the input sequence
had (or somehow acquired) a \231 character.
Make sure that route-addrs always have <angle brackets> around
them in non-SMTP envelopes (SMTP envelopes already do
this properly).
Avoid weird headers on unbalanced punctuation of the form:
``Joe User <user)'' -- this caused reference to the
null macro. Fix from Rick McCarty of IO.COM.
Fix a problem that caused an alias "user: user@local.host" to
not have the QNOTREMOTE bit set; this caused configs
to act as if FEATURE(notsticky) was defined even when
it was not. The effect of the problem was to make it
very hard to to set up satellite sites that had a few
local accounts, with everything else forwarded to a
corporate hub. Reported by Detlef Drewanz of the
University of Rostock and Mark Frost of NCD.
Change queuing to not call rulesets 3, {1 or 2}, 4 on header
addresses. This is more efficient (fewer name server
calls) and fixes certain unusual configurations, such
as those that have ruleset 4 do something that is
non-idempotent unless a mailer-specific ruleset did
something else. Problem reported by Brian J. Coan
of the Institute for Global Communications.
Fix the "obsolete argument" routine in main to better understand
new arguments. For example, if you used ``sendmail
-C config -v -q'' it would choke on the -q because
the -C would stop looking for old-format arguments.
Fix the code that was intended to allow two users to forward their
mail to the same program and have them appear unique.
Portability fixes for:
SCO UNIX from Murray Kucherawy.
SCO Open Server 3.2v4 from Philippe Brand.
System V Release 4 from Rick Ellis and others.
OSF/1 from Steve Campbell.
DG/UX from Ben Mesander of the USGS and Bryan Curnutt
of Stoner Associates.
Motorola SysV88 from Kevin Johnson of Motorola.
Solaris 2.3 from Casper H.S. Dik of the University
of Amsterdam and John Caruso of University
of Maryland.

RISC/os.
Linux from John Kennedy of California State University
at Chico.
Solaris 2.x from Tony Boner of the U.S. Air Force.
NEXTSTEP 3.x from Vince DeMarco.
HP-UX from various people. NOTA BENE: the location
of the config file has moved to /usr/lib
to match the HP-UX version of sendmail.
CONFIG: Don't do any recipient rewriting on relay mailer;
since this is intended only for internal use, the
usual RFC 821/822/1123 rules can be relaxed. The
main point of this is to avoid munging (ugh) UUCP
addresses when relaying internally.
CONFIG: fix typo in mailer/uucp.m4 that mutilates list:;
syntax addresses delivered via UUCP. Solution
provided by Peter Wemm.
CONFIG: fix thumb-fumble in default UUCP relaying in ruleset
zero; it caused double @ signs in addresses. From
Irving Reid of the University of Toronto.
CONFIG: Portability fixes for SCO Unix 3.2 with TCP/IP 1.2.1
from Markku Toijala of ICL Personal Systems Oy.
CONFIG: Add trailing "." on pseudo-domains for consistency;
this fixes a problem (noted by Al Whaley of Sunnyside)
that made it hard to recognize your own pseudodomain
names.
CONFIG: catch "@host" syntax errors (i.e., null local-parts)
rather than letting them get "local configuration
error"s. Problem noted by John Gardiner Myers.
CONFIG: add uucp-uudom mailer variant, based on code posted
by Spider Boardman <spider@Orb.Nashua.NH.US>; this
has uucp-dom semantics but old UUCP syntax. This
also permits "uucp-old" as an alias for "uucp" and
"uucp-new" as a synonym for "suucp" for consistency.
CONFIG: add POP mailer support (from Kimmo Suominen
<kim@grendel.lut.fi>).
CONFIG: drop CSNET_RELAY support -- CSNET is long gone.
CONFIG: fix bug caused with domain literal addresses (e.g.,
``[128.32.131.12]'') when FEATURE(allmasquerade)
was set; it would get an additional @masquerade.host
added to the address. Problem noted by Peter Wan
of Georgia Tech.
CONFIG: make sure that the local UUCP name is in $=w. From
Jim Murray of Stratus.
CONFIG: changes to UUCP rewriting to simulate IDA-style "V"
mailer flag. Briefly, if you are sending to host
"foo", then it rewrites "foo!...!baz" to "...!baz",
"foo!baz" remains "foo!baz", and anything else has
the local name prepended.
CONFIG: portability fixes for HP-UX.
DOC: several minor problems fixed in the Install & Op Guide.
MAKEMAP: fix core dump problem on lines that are too long or
which lack newline. From Mark Delany.
MAILSTATS: print sums of columns (total messages & kbytes
in and out of the system). From Tom Ferrin of UC
San Francisco Computer Graphics Lab.
SIGNIFICANT USER- OR SYSAD-VISIBLE CHANGES:
On HP-UX, /etc/sendmail.cf has been moved to
/usr/lib/sendmail.cf to match HP sendmail.
Permissions have been tightened up on world-writable
:include: files and accounts that have shells
that are not listed in /etc/shells. This may
cause some .forward files that have worked
before to start failing.
SIGUSR1 dumps some state to the log.

8.6.4/8.6.4 1993/10/31
Repair core-dump problem (write to read-only memory segment)
if you fall back to the return-to-Postmaster case in
savemail. Problem reported by Richard Liu.
Immediately diagnose bogus sender addresses in SMTP. This
makes quite certain that crackers can't use this
class of attack.
Reliability Fix: check return value from fclose() and fsync()
in a few critical places.
Minor problem in initsys() that reversed a condition for
redirecting the output channel on queue runs. It's
not clear this code even does anything. From Eric
Wassenaar of the Dutch National Institute for Nuclear
and High-Energy Physics.
Fix some problems that caused queue runs to do "too much work",
such as double-reading the Errors-To: header. From
Eric Wassenaar.
Error messages on writing the temporary file (including the
data file) were getting suppressed in SMTP -- this
fix causes them to be properly reported. From Eric
Wassenaar.
Some changes to support AF_UNIX sockets -- this will only
really become relevant in the next release, but some
people need it for local patches. From Michael
Corrigan of UC San Diego.
Use dynamically allocated memory (instead of static buffers)
for macros defined in initsys() and settime(); since
these can have different values depending on which
envelope they are in. From Eric Wassenaar.
Improve logging to show ctladdr on to= logging; this tells you
what uid/gid processes ran as.
Fix a problem that caused error messages to be discarded if
the sender address was unparseable for some reason;
this was supposed to fall back to the "return to
postmaster" case.
Improve aliaswait backoff algorithm.
Portability patches for Linux (8.6.3 required another header
file) (from Karl London) and SCO UNIX.
CONFIG: patch prog mailer to not strip host name off of envelope
addresses (so that it matches local again). From
Christopher Davis.
CONFIG: change uucp-dom mailer so that "<>" translates to $n;
this prevents uux from seeing lines with null names like
``From Sat Oct 30 14:55:31 1993''. From Motonori
Nakamura of Kyoto University.
CONFIG: handle <list:;> syntax correctly. This isn't legal, but
it shouldn't fail miserably. From Motonori Nakamura.
8.6.2/8.6.2 1993/10/15
Put a "successful delivery" message in the transcript for
addresses that get return-receipts.
Put a prominent "this is only a warning" message in warning
messages -- some people don't read carefully enough
and end up sending the message several times.
Include reason for temporary failure in the "warning" return
message. Currently, it just says "cannot send for
four hours".
Fix the "Original message received" time generated for
returntosender messages. It was previously listed as
the current time. Bug reported by Eric Hagberg of
Cornell University Medical College.
If there is an error when writing the body of a message,
don't send the trailing dot and wait for a response
in sender SMTP, as this could cause the connection to
hang up under some bizarre circumstances. From Eric
Wassenaar.
Fix some server SMTP synchronization problems caused when
connections fail during message collection. From
Eric Wassenaar.
Fix a problem that can cause srvrsmtp to reject mail if the
name server is down -- it accepts the RCPT but rejects
the DATA command. Problem reported by Jim Murray of
Stratus.
Fix a problem that can cause core dumps if the config file
incorrectly resolves to a null hostname. Reported by
Allan Johannesen of WPI.
Non-root use of -C flag, dangerous -f flags, and use of -oQ
by non-root users were not put into
X-Authentication-Warning:s as intended because the
config file hadn't set the PrivacyOptions yet. Fix
from Sven-Ove Westberg of the University of Lulea.
Under very odd circumstances, the alias file rebuild code
could get confused as to whether a database was
open or not.
Check "vendor code" on the end of V lines -- this is
intended to provide a hook for vendor-specific
configuration syntax. (This is a "new feature",
but I've made an exception to my rule in a belief
that this is a highly exceptional case.)
Portability fixes for DG/UX (from Douglas Anderson of NCSC),
SCO Unix (from Murray Kucherawy), A/UX, and OSF/1
(from Jon Forrest of UC Berkeley)
CONFIG: fix ``mailer:host'' form of UUCP relay naming.
8.6.1/8.6 1993/10/08
Portability fixes for A/UX and Encore UMAX V.
Fix error message handling -- if you had a name server down
causing an error during parsing, that message was never
propagated to the queue file.
8.6/8.6 1993/10/05
Configuration cleanup: make it easier to undo IDENTPROTO in
conf.h (other systems have the same bug).
If HASGETDTABLESIZE and _SC_OPEN_MAX are both defined, assume
getdtablesize() instead of sysconf(); a disturbingly
large number of systems defined _SC_OPEN_MAX in the
header files but don't have the syscall.
Another patch to really truly ignore MX records in getcanonname
if trymx == FALSE.
Fix problem that caused the "250 IAA25499 Message accepted for
delivery" message to be omitted if there was an error
in the header of the message (e.g., a bad Errors-To:
line). Pointed out by Michael Corrigan of UCSD.
Announce name of host we are chatting when we get errors; this
is an IDA-ism suggested by Christophe Wolfhugel.
Portability fixes for Alpha OSF/1 (from Anthony Baxter of the
Australian Artificial Intelligence Institute), SCO Unix
(from Murray Kucherawy of Hookup Communication Corp.),
NeXT (from Vince DeMarco and myself), Linux (from
Karl London <karl@borg.demon.co.uk>), BSDI (from
Christophe Wolfhugel, and SVR4 on Dell (from Kimmo
Suominen), AUX 3.0 on Macintosh, and ANSI C compilers.
Some changes to get around gcc optimizer bugs. From Takahiro
Kanbe.
Fix error recovery in queueup if another tf file of the same
name already exists. Problem stumbled over by Bill
Wisner of The Well.
Output YP_MASTER_NAME and YP_LAST_MODIFIED without null bytes.
Problem noted by Keith McMillan of Ameritech Services.
Deal with group permissions properly when opening .forward and
:include: files. This relaxes the 8.1C restrictions
slightly more. This includes proper setting of groups
when reading :include: files, allowing you to read some
files that you should be able to read but have previously
been denied unless you owned them or they had "other"
read permission.
Make certain that $j is in $=w (after the .cf is read) so that
if the user is forced to override some silly system,
MX suppression will still work.
Fix a couple of efficiency problems where newstr was double-
calling expensive routines. In at least one case, it
wasn't guaranteed that they would always return the
same result. Problem noted by Christophe Wolfhugel.
Fix null pointer dereference in putoutmsg -- only on an error
condition from a non-SMTP mailer. From Motonori
Nakamura.
Macro expand "C" line class definitions before scanning so that
"CX $Z" works.
Fix problem that caused error message to be sent while still
trying to send the original message if the connection
is closed during a DATA command after getting an error
on an RCPT command (pretty obscure). Problem reported
by John Myers of CMU.
Fix reply to NOOP to be 250 instead of 200 -- this is a long
term bug.
Fix a nasty bug causing core dumps when returning the "warning:
cannot deliver for N hours -- will keep trying" message;
it only occurred if you had PostmasterCopy set and
only on some architectures. Although sendmail would
keep trying, it would send error messages on each
queue interval. This is an important fix.
Allow u and g options to take user and group names respectively.
Don't do a chdir into the queue directory in -bt mode to make
ruleset testing a bit easier.
Don't allow users to turn off logging (using -oL) on the command
line -- command line can only raise, not lower, logging
level.
Set $u to the original recipient on the SMTP transaction or on
the command line. This is only done if there is exactly
one recipient. Technically, this does not meet the
specs, because it does not guarantee a domain on the
address.
Fix a problem that dumped error messages on bad addresses if
you used the -t flag. Problem noted by Josh Smith of
Harvey Mudd College.
Given an address such as ``<foo> <bar>'', auto-quote the first
``<foo>'' part, giving ``"<foo>" <bar>''. This is to
avoid the problem of people who use angle brackets in
their full name information.
Fix a null pointer dereference if you set option "l", have
an Errors-To: header in the message, and have Errors-To:
defined in the config file H lines. From J.R. Oldroyd.
Put YPCOMPAT on #ifdef NIS instead -- it's one less thing to get
wrong when compiling. Suggested by Rick McCarty of TI.
Fix a problem that could pass negative SIZE parameter if the
df file got lost; this would cause servers to always
give a temporary failure, making the problem even worse.
Problem noted by Allan Johannesen of WPI.
Add "ident" timeout (one of the "r" option selectors) for IDENT
protocol timeouts (30s default). Requested by Murray
Kucherawy of HookUp Communication Corp. to handle bogus
PC TCP/IP implementations.
Change $w default definition to be just the first component of
the domain name on config level 5. The $j macro defaults
to the FQDN; $m remains as before. This lets well-behaved
config files use any of the short, long, or subdomain
names.
Add makesendmail script in src to try to automate multi-architecture
builds. I know, this is sub-optimal, but it is still
helpful.
Fix very obscure race condition that can cause a queue run to
get a queue file for an already completed job. This
problem has existed for years. Problem noted by the
long suffering Allan Johannesen of WPI.
Fix a problem that caused the raw sender name to be passed to
udbsender instead of the canonified name -- this caused
it to sometimes miss records that it should have found.
Relax check of name on HELO packet so that a program using -bs
that claims to be itself works properly.
Restore rewriting of $: part of address through 2, R, 4 in
buildaddr -- this requires passing a lot of flags to get
it right. Unlike old versions, this ONLY rewrites
recipient addresses, not sender addresses.
Fix a bug that caused core dumps in config files that cannot
resolve /file/name style addresses. Fix from Jonathan
Kamens of OpenVision Technologies.
Fix problem with fcntl locking that can cause error returns to
be lost if the lock is lost; this required fully
queueing everything, dropping the envelope (so errors
would get returned), and then re-reading the queue from
scratch.
Fix a problem that caused aliases that redefine an otherwise
true address to still send to the original address
if and only if the alias failed in certain bizarre
ways (e.g, if they pointed at a list:; syntax address).
Problem pointed out by Jonathan Kamens.
Remove support for frozen configuration files. They caused
more trouble than it was worth.
Fix problem that can cause error messages to get ignored when
using both -odb and -t flags. Problem noted by Rob
McNicholas at U.C. Berkeley.
Include all "normal" variations on hostname in $=w. For example,
if the host name is vangogh.cs.berkeley.edu, $=w will
contain vangogh, vangogh.cs, and vangogh.cs.berkeley.edu.
Add "restrictqrun" privacy flag -- without this, anyone can run
the queue.
Reset SmtpPhase global on initial connection creation so that
messages don't come out with stale information.
Pass an "ext" argument to lockfile so that error/log messages
will properly reflect the true filename being locked.
Put all [...] address forms into $=w -- this eliminates the need
for MAXIPADDR in conf.h. Suggested by John Gardiner
Myers of CMU.
Fix a bug that can cause qf files to be left around even after
an SMTP RSET command. Problem and fix from Michael
Corrigan.
Don't send a PostmasterCopy to errors when the Precedence: is
negative. Error reports still go to the envelope
sender address.
Add LA_SHORT for load averages.
Lock sendmail.st file when posting statistics.
Add "SendBufSize" and "RcvBufSize" suboptions to "O" option to
set the size of the TCP send and receive buffers; if you
run over a slow slip line you may need to set these down
(although it would be better to fix the SLIP implementation
so that it's not necessary to recompile every program
that does bulk data transfer).
Allow null defaults on $( ... $) lookups. Problem reported by
Amir Plivatsky.
Diagnose crufty S and V config lines. This resulted from an
observation that some people were using the SITE macro
without the SITECONFIG macro first, which was causing
bogus config files that were not caught.
Fix makemap -f flag to turn off case folding (it was turning it
on instead). THIS IS A USER VISIBLE CHANGE!!!
Fix a problem that caused multiple error messages to be sent if
you used "sendmail -t -oem -odb", your system uses fcntl
locking, and one of the recipient addresses is unknown.
Reset uid earlier in include() so that recursive .forwards or
:include:s don't use the wrong uid.
If file descriptor 0, 1, or 2 was closed when sendmail was
called, the code to recover the descriptor was broken.
This sometimes (only sometimes) caused problems with the
alias file. Fix from Motonori Nakamura.
Fix a problem that caused aliaswait to go into infinite recursion
if the @:@ metasymbol wasn't found in the alias file.
Improve error message on newaliases if database files cannot be
opened or if running with no database format defined.
Do a better estimation of the size of error messages when NoReturn
is set. Problem noted by P{r (Pell) Emanuelsson.
Fix a problem causing the "c" option (don't connect to expensive
mailers) to be ignored in SMTP. Problem noted and the
solution suggested by Robert Elz of The University of
Melbourne.
Improve connection caching algorithm by passing "[host]" to
hostsignature, which strips the square brackets and
returns the real name. This allows mailertable entries
to match regular entries.
Re-enable Return-Receipt-To: -- people seem to want this stupid
feature, even if it doesn't work right.
Catch and log attempts to try the "wiz" command in server SMTP.
This also ups the log level from LOG_NOTICE to LOG_CRIT.
Be more generous at assigning $z to the home directory -- do this
for programs that are specified through a .forward file.
Fix from Andrew Chang of Sun Microsystems.
Always save a fatal error message in preference to a non-fatal
error message so that the "subject" line of return
messages is the best possible.
CONFIG: reduce the number of quotes needed to quote configuration
parameters with commas: two quotes should work now, e.g.,
define(ALIAS_FILE, ``/etc/aliases,/etc/aliases.local'').
CONFIG: class $=Z is a set of UUCP hosts that use uucp-dom
connections (domain-ized UUCP).
CONFIG: fix bug in default maps (-o must be before database file
name). Pointed out by Christophe Wolfhugel.
CONFIG: add FEATURE(nodns) to state that we are not relying on
DNS. This would presumably be used in UUCP islands.
CONFIG: add OSTYPE(nextstep) and OSTYPE(linux).
CONFIG: log $u in Received: line. This is in technical violation
of the standards, since it doesn't guarantee a domain
on the address.
CONFIG: don't assume "m" in local mailer flags -- this means that
if you redefine LOCAL_MAILER_FLAGS you will have to include
the "m" flag should you want it. Apparently some Solaris 2.2
installations can't handle multiple local recipients.
Problem noted by Josh Smith.
CONFIG: add confDOMAIN_NAME to set $j (if undefined, $j defaults).
CONFIG: change default version level from 4 to 5.
CONFIG: add FEATURE(nullclient) to create a config file that
forwards all mail to a hub without ever looking at the
addresses in any detail.
CONFIG: properly strip mailer: information off of relays when
used to change .BITNET form into %-hack form.
CONFIG: fix a problem that caused infinite loops if presented
with an address such as "!foo".
CONFIG: check for self literal (e.g., [128.32.131.12]) even if
the reverse "PTR" mapping is broken. There's a better
way to do this, but the change is fairly major and I
want to hold it for another release. Problem noted by
Bret Marquis.
8.5/8.5 1993/07/23
Serious bug: if you used a command line recipient that was unknown
sendmail would not send a return message (it was treating
everything as though it had an SMTP-style client that
would do the return itself). Problem noted by Josh Smith.
Change "trymx" option in getcanonname() to ignore all MX data,
even during a T_ANY query. This actually didn't break
anything, because the only time you called getcanonname
with !trymx was if you already knew there were no MX
records, but it is somewhat cleaner. From Motonori
Nakamura.
Don't call getcanonname from getmxrr if you already know there
are no DNS records matching the name.
Fix a problem causing error messages to always include "The
original message was received ... from localhost".
The correct original host information is now included.
Previous change to cf/sh/makeinfo.sh doesn't port to Ultrix (their
version of "test" doesn't have the -x flag). Change it
to use -f instead. From John Myers.
CONFIG: 8.4 mistakenly set the default SMTP-style mailer to
esmtp -- it should be smtp.
CONFIG: send all relayed mail using confRELAY_MAILER (defaults
to "relay" (a variant of "smtp") if MAILER(smtp) is used,
else "suucp" if MAILER(uucp) is used, else "unknown");
this cleans up the configs somewhat. This fixes a serious
problem that caused route-addrs to get mistaken as relays,
pointed out by John Myers. WARNING: this also causes
the default on SMART_HOST to change from "suucp" to
"relay" if you have MAILER(smtp) specified.
8.4/8.4 1993/07/22
Add option `w'. If you receive a message that comes to you because
you are the best (lowest preference) target of an MX, and
you haven't explicitly recognized the source MX host in
your .cf file, this option will cause you to try the target
host directly (as if there were no MX for it at all). If
`w' is not set, this case is a configuration error.
Beware: if `w' is set, senders may get bogus errors like
"message timed out" or "host unknown" for problems that
are really configuration errors. This option is
disrecommended, provided only for compatibility with
UIUC sendmail.
Fix a problem that caused the incoming socket to be left open
when sendmail forks after the DATA command. This caused
calling systems to wait in FIN_WAIT_2 state until the
entire list was processed and the child closed -- a
potentially prodigious amount of time. Problem noted
by Neil Rickert.
Fix problem (created in 6.64) that caused mail sent to multiple
addresses, one of which was a bad address, to completely
suppress the sending of the message. This changes
handling of EF_FATALERRS somewhat, and adds an
EF_GLOBALERRS flag. This also fixes a potential problem
with duplicate error messages if there is a syntax error
in the header of a message that isn't noticed until late
in processing. Original problem pointed out by Josh Smith
of Harvey Mudd College. This release includes quite a bit
of dickering with error handling (see below).
Back out SMTP transaction if MAIL gets nested 501 error. This
will only hurt already-broken software and should help
humans.
Fix a problem that broke aliases when neither NDBM nor NEWDB were
compiled in. It would never read the alias file.
Repair unbalanced `)' and `>' (the "open" versions are already
repaired).
Logging of "done" in dropenvelope() was incorrect: it would
log this even when the queue file still existed. Change
this to only log "done" (at log level 11) when the
queue file is actually removed. From John Myers.
Log "lost connection" in server SMTP at log level 20 if there
is no pending transaction. Some senders just close the
connection rather than sending QUIT.
Fix a bug causing getmxrr to add a dot to the end of unqualified
domains that do not have MX records -- this would cause
the subsequent host name lookup to fail. The problem
only occurred if you had FEATURE(nocanonify) set.
Problem noted by Rick McCarty of Texas Instruments.
Fix invocation of setvbuf when passed a -X flag -- I had
unwittingly used an ANSI C extension, and this caused
core dumps on some machines.
Diagnose self-destructive alias loops on RCPT as well as EXPN.
Previously it just gave an empty send queue, which
then gave either "Need RCPT (recipient)" at the DATA
(confusing, since you had given an RCPT command which
returned 250) or just dropped the email, depending on
whether you were running VERBose mode. Now it usually
diagnoses this case as "aliasing/forwarding loop broken".
Unfortunately, it still doesn't adequately diagnose
some true error conditions.
Add internal concept of "warning messages" using 6xx codes.
These are not reported only to Postmaster. Unbalanced
parens, brackets, and quotes are printed as 653 codes.
They are always mapped to 5xx codes before use in SMTP.
Clean up error messages to tell both the actual address that
failed and the alias they arose from. This makes it
somewhat easier to diagnose problems. Difficulty noted
by Motonori Nakamura.
Fix a problem that inappropriately added a ctladdr to addresses
that shouldn't have had one during a queue run. This
caused error messages to be handled differently during
a queue run than a direct run.
Don't print the qf name and line number if you get errors during
the direct run of the queue from srvrsmtp -- this was
just extra stuff for users to crawl through.
Put command line flags on second line of pid file so you can
auto-restart the daemon with all appropriate arguments.
Use "kill `head -1 /etc/sendmail.pid`" to stop the
daemon, and "eval `tail -1 /etc/sendmail.pid`" to
restart it.
Remove the ``setuid(getuid())'' in main -- this caused the
IDENT daemon to screw up. This required that I change
HASSETEUID to HASSETREUID and complicate the mode
changing somewhat because both Ultrix and SunOS seem
to have a bug causing seteuid() to set the saved uid
as well as the effective. The program test/t_setreuid.c
will test to see if your implementation of setreuid(2)
is appropriately functional.
The FallBackMX (option V) handling failed to properly identify
fallback to yourself -- most of the code was there,
but it wasn't being enabled. Problem noted by Murray
Kucherawy of the University of Waterloo.
Change :include: open timeout from ETIMEDOUT to an internal
code EOPENTIMEOUT; this avoids adding "during SmtpPhase
with CurHostName" in error messages, which can be
confusing. Reported by Jonathan Kamens of OpenVision
Technologies.
Back out setpgrp (setpgid on POSIX systems) call to reset the
process group id. The original fix was to get around
some problems with recalcitrant MUAs, but it breaks
any call from a shell that creates a process group id
different from the process id. I could try to fix
this by diddling the tty owner (using tcsetpgrp or
equivalent) but this is too likely to break other
things.
Portability changes:
Support -M as equivalent to -oM on Ultrix -- apparently
DECnet calls sendmail with -MrDECnet -Ms<HOST> -bs
instead of using standard flags. Oh joy. This
behavior reported by Jon Giltner of University
of Colorado.
SGI IRIX -- this includes several changes that should
help other strict ANSI compilers.
SCO Unix -- from Murray Kucherawy of HookUp Communication
Corporation.
Solaris running the Sun C compiler (which despite the
documentation apparently doesn't define
__STDC__ by default).
ConvexOS from Eric Schnoebelen of Convex.
Sony NEWS workstations and Omron LUNA workstations from
Motonori Nakamura.
CONFIG: add confTRY_NULL_MX_LIST to set option `w'.
CONFIG: delete `C' and `e' from default SMTP mailers flags;
several people have made a good argument that this
creates more problems than it solves (although this
may prove painful in the short run).
CONFIG: generalize all the relays to accept a "mailer:host"
format.
CONFIG: move local processing in ruleset 0 into a new ruleset
98 (8 on old sendmail). Domain literal [a.b.c.d]
addresses are also passed through this ruleset.
CONFIG: if neither SMART_HOST nor MAILER(smtp) were defined,
internet-style addresses would "fall off the end" of
ruleset zero and be interpreted as local -- however,
the angle brackets confused the recursive call.
These are now diagnosed as "Unrecognized host name".
CONFIG: USENET rules weren't included in S0 because of a mistaken
ifdef(`_MAILER_USENET_') instead of
ifdef(`_MAILER_usenet_'). Problem found by Rein Tollevik
of SINTEF RUNIT, Oslo.
CONFIG: move up LOCAL_RULE_0 processing so that it happens very
early in ruleset 0; this allows .mc authors to bypass
things like the "short circuit" code for local addresses.
Prompted by a comment by Bill Wisner of The Well.
CONFIG: add confSMTP_MAILER to define the mailer used (smtp or
esmtp) to send SMTP mail. This allows you to default
to esmtp but use a mailertable or other override to
deal with broken servers. This logic was pointed out
to me by Bill Wisner. Ditto for confLOCAL_MAILER.
Changes to cf/sh/makeinfo.sh to make it portable to SVR4
environments. Ugly as sin.
8.3/8.3 1993/07/13
Fix setuid problems introduced in 8.2 that caused messages
like "Cannot create qfXXXXXX: Invalid argument"
or "Cannot reopen dfXXXXXX: Permission denied". This
involved a new compile flag "HASSETEUID" that takes
the place of the old _POSIX_SAVED_IDS -- it turns out
that the POSIX interface is broken enough to break
some systems badly. This includes some fixes for
HP-UX. Also fixes problems where the real uid is
not reset properly on startup (from Neil Rickert).
Fix a problem that caused timed out messages to not report the
addresses that timed out. Error messages are also more
"user friendly".
Drop required bandwidth on connections from 64 bytes/sec to
16 bytes/sec.
Further Solaris portability changes -- doesn't require the BSD
compatibility library. This also adds a new
"HASGETDTABLESIZE" compile flag which can be used if
you want to use getdtablesize(2) instead of sysconf(2).
These are loosely based on changes from David Meyer at
University of Oregon. This now seems to work, at least
for quick test cases.
Fix a problem that can cause duplicate error messages to be
sent if you are in SMTP, you send to multiple addresses,
and at least one of those addresses is good and points
to an account that has a .forward file (whew!).
Fix a problem causing messages to be discarded if checkcompat()
returned EX_TEMPFAIL (because it didn't properly mark
the "to" address). Problem noted by John Myers.
Fix dfopen to return NULL if the open failed; I was depending
on fdopen(-1) returning NULL, which isn't the case. This
isn't serious, but does result in weird error diagnoses.
From Michael Corrigan.
CONFIG: add UUCP_MAX_SIZE M4 macro to set the maximum size of
messages sent through UUCP-family mailers. Suggested
by Bill Wisner of The Well.
CONFIG: if both MAILER(uucp) and MAILER(smtp) are specified,
include a "uucp-dom" mailer that uses domain-style
addressing. Suggested by Bill Wisner.
CONFIG: Add LOCAL_SHELL_FLAGS and LOCAL_SHELL_ARGS to match
LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS. Suggested by
Christophe Wolfhugel.
CONFIG: Add OSTYPE(aix3). From Christophe Wolfhugel.
8.2/8.2 1993/07/11
Don't drop out on config file parse errors in -bt mode.
On older configuration files, assume option "l" (use Errors-To
header) for back compatibility. NOTE: this DOES NOT
imply an endorsement of the Errors-To: header in any way.
Accept -x flag on AIX-3 as well as OSF/1. Why, why, why???
Don't log errors on EHLO -- it isn't a "real" error for an old
SMTP server to give an error on this command, and
logging it in the transcript can be confusing. Fix
from Bill Wisner.
IRIX compatibility changes provided by Dan Rich
<drich@sandman.lerc.nasa.gov>.
Solaris 2 compatibility changes. Provided by Bob Cunningham
<bob@kahala.soest.hawaii.edu>, John Oleynick
<juo@klinzhai.rutgers.edu>
Debugging: -d17 was overloaded (hostsignature and usersmtp.c);
move usersmtp (smtpinit and smtpmailfrom) to -d18 to
match the other flags in that file.
Flush transcript before fork in mailfile(). From Eric Wassenaar.
Save h_errno in mci struct and improve error message display.
Changes from Eric Wassenaar.
Open /dev/null for the transcript if the create of the xf file
failed; this avoids at least one possible null pointer
reference in very weird cases. From Eric Wassenaar.
Clean up statistics gathering; it was over-reporting because of
forks. From Eric Wassenaar.
Fix problem that causes old Return-Path: line to override new
Return-Path: line (conf.c needs H_FORCE to avoid
re-using old value). From Motonori Nakamura.
Fix broken -m flag in K definition -- even if -m (match only)
was specified, it would still replace the key with the
value. Noted by Rick McCarty of Texas Instruments.
If the name server timed out over several days, no "timed out"
message would ever be sent back. The timeout code
has been moved from markfailure() to dropenvelope()
so that all such failures should be diagnosed. Pointed
out by Christophe Wolfhugel and others.
Relax safefile() constraints: directories in an include or
forward path must be readable by self if the controlling
user owns the entry, readable by all otherwise (e.g.,
when reading your .forward file, you have to own and
have X permission in it; everyone needs X permission in
the root and directories leading up to your home);
include files must be readable by anyone, but need not
be owned by you.
If _POSIX_SAVED_IDS is defined, setuid to the owner before
reading a .forward file; this gets around some problems
on NFS mounts if root permission is not exported and
the user's home directory isn't x'able.
Additional NeXT portability enhancements from Axel Zinser.
Additional HP-UX portability enhancements from Brian Bullen.
Add a timeout around SMTP message writes; this assumes you can
get throughput of at least 64 bytes/second. Note that
this does not impact the "datafinal" default, which
is separate; this is just intended to work around
network clogs that will occur before the final dot
is sent. From Eric Wassenaar.
Change map code to set the "include null" flag adaptively --
it initially tries both, but if it finds anything
matching without a null it never tries again with a
null and vice versa. If -N is specified, it never
tries without the null and creates new maps with a
null byte. If -O is specified, it never tries with
the null (for efficiency). If -N and -O are specified,
you get -NO (get it?) lookup at all, so this would
be a bad idea. If you don't specify either -N or -O,
it adapts.
Fix recognition of "same from address" so that MH submissions
will insert the appropriate full name information;
this used to work and got broken somewhere along the
way.
Some changes to eliminate some unnecessary SYSERRs in the
log. For example, if you lost a connection, don't
bother reporting that fact on the connection you lost.
Add some "extended debugging" flags to try to track down
why we get occasional problems with file descriptor
one being closed when execing a mailer; it seems to
only happen when there has been another error in the
same transaction. This requires XDEBUG, defined
by default in conf.h.
Add "-X filename" command line flag, which logs both sides of
all SMTP transactions. This is intended ONLY for
debugging bad implementations of other mailers; start
it up, send a message from a mailer that is failing,
and then kill it off and examine the indicated log.
This output is not intended to be particularly human
readable. This also adds the HASSETVBUF compile
flag, defaulted on if your compiler defines __STDC__.
CONFIG: change SMART_HOST to override an SMTP mailer. If you
have a local net that should get direct connects, you
will need to use LOCAL_NET_CONFIG to catch these hosts.
See cf/README for an example.
CONFIG: add LOCAL_MAILER_ARGS (default: `mail -d $u') to handle
sites that don't use the -d flag.
CONFIG: hide recipient addresses as well as sender addresses
behind $M if FEATURE(allmasquerade) is specified; this
has been requested by several people, but can break
local aliases. For example, if you mail to "localalias"
this will be rewritten as "localalias@masqueradehost";
although initial delivery will work, replies will be
broken. Use it sparingly.
CONFIG: add FEATURE(domaintable). This maps unqualified domains
to qualified domains in headers. I believe this is
largely equivalent to the IDA feature of the same name.
CONFIG: use $U as UUCP name instead of $k. This permits you
to override the "system name" as your UUCP name --
in particular, to use domain-ized UUCP names. From
Bill Wisner of The Well.
CONFIG: create new mailer "esmtp" that always tries EHLO
first. This is currently unused in the config files,
but could be used in a mailertable entry.
8.1C/8.1B 1993/06/27
Serious security bug fix: it was possible to read any file on
the system, regardless of ownership and permissions.
If a subroutine returns a fully qualified address, return it
immediately instead of feeding it back into rewriting.
This fixes a problem with mailertable lookups.
CONFIG: fix some M4 frotz (concat => CONCAT)
8.1B/8.1A 1993/06/12
Serious bug fix: pattern matching backup algorithm stepped by
two tokens in classes instead of one. Found by Claus
Assmann at University of Kiel, Germany.
8.1A/8.1A 1993/06/08
Another mailertable fix....
8.1/8.1 1993/06/07
4.4BSD freeze. No semantic changes.

SENDMAIL CONFIGURATION FILES
This document describes the sendmail configuration files. It
explains how to create a sendmail.cf file for use with sendmail.
It also describes how to set options for sendmail which are explained
in the Sendmail Installation and Operation guide (doc/op/op.me).
To get started, you may want to look at tcpproto.mc (for TCP-only
sites) and clientproto.mc (for clusters of clients using a single
mail host), or the generic-*.mc files as operating system-specific
examples.

+--------------------------+
| INTRODUCTION AND EXAMPLE |
+--------------------------+
Configuration files are contained in the subdirectory "cf", with a
suffix ".mc". They must be run through "m4" to produce a ".cf" file.
You must pre-load "cf.m4":
m4 ${CFDIR}/m4/cf.m4 config.mc > config.cf
Alternatively, you can simply:
cd ${CFDIR}/cf
./Build config.cf
where ${CFDIR} is the root of the cf directory and config.mc is the
name of your configuration file. If you are running a version of M4
that understands the __file__ builtin (versions of GNU m4 >= 0.75 do
this, but the versions distributed with 4.4BSD and derivatives do not)
or the -I flag (ditto), then ${CFDIR} can be in an arbitrary directory.
For "traditional" versions, ${CFDIR} ***MUST*** be "..", or you MUST
use -D_CF_DIR_=/path/to/cf/dir/ -- note the trailing slash! For example:
m4 -D_CF_DIR_=${CFDIR}/ ${CFDIR}/m4/cf.m4 config.mc > config.cf
Let's examine a typical .mc file:
divert(-1)

# By using this file, you agree to the terms and conditions set

#
#
# This is a Berkeley-specific configuration file for HP-UX 9.x.
# It applies only to the Computer Science Division at Berkeley,
# and should not be used elsewhere. It is provided on the sendmail
# distribution as a sample only. To create your own configuration
# file, create an appropriate domain file in ../domain, change the
# `DOMAIN' macro below to reference that file, and copy the result
# to a name of your own choosing.
#
divert(0)
The divert(-1) will delete the crud in the resulting output file.
The copyright notice can be replaced by whatever your lawyers require;
our lawyers require the one that is included in these files. A copyleft
is a copyright by another name. The divert(0) restores regular output.
VERSIONID(`<SCCS or RCS version id>')
VERSIONID is a macro that stuffs the version information into the
resulting file. You could use SCCS, RCS, CVS, something else, or
omit it completely. This is not the same as the version id included
in SMTP greeting messages -- this is defined in m4/version.m4.
OSTYPE(`hpux9')dnl
You must specify an OSTYPE to properly configure things such as the
pathname of the help and status files, the flags needed for the local
mailer, and other important things. If you omit it, you will get an
error when you try to build the configuration. Look at the ostype
directory for the list of known operating system types.
DOMAIN(`CS.Berkeley.EDU')dnl
This example is specific to the Computer Science Division at Berkeley.
You can use "DOMAIN(`generic')" to get a sufficiently bland definition
that may well work for you, or you can create a customized domain
definition appropriate for your environment.
MAILER(`local')
MAILER(`smtp')
These describe the mailers used at the default CS site. The local
mailer is always included automatically. Beware: MAILER declarations
should only be followed by LOCAL_* sections. The general rules are
that the order should be:
VERSIONID
OSTYPE
DOMAIN
FEATURE
local macro definitions
MAILER
LOCAL_CONFIG
LOCAL_RULE_*
LOCAL_RULESETS
There are a few exceptions to this rule. Local macro definitions which
influence a FEATURE() should be done before that feature. For example,
a define(`PROCMAIL_MAILER_PATH', ...) should be done before
FEATURE(`local_procmail').
*******************************************************************
*** BE SURE YOU CUSTOMIZE THESE FILES! They have some ***
*** Berkeley-specific assumptions built in, such as the name ***
*** of their UUCP-relay. You'll want to create your own ***
*** domain description, and use that in place of ***
*** domain/Berkeley.EDU.m4. ***
*******************************************************************
Note:
Some rulesets, features, and options are only useful if the sendmail
binary has been compiled with the appropriate options, e.g., the
ruleset tls_server is only invoked if sendmail has been compiled
with STARTTLS. This is usually obvious from the context and hence
not further specified here.
There are also so called "For Future Releases" (FFR) compile time
options which might be included in a subsequent version or might
simply be removed as they turned out not to be really useful.
These are generally not documented but if they are, then the required
compile time options are listed in doc/op/op.* for rulesets and
macros, and for mc/cf specific options they are usually listed here.
In addition to compile time options for the sendmail binary, there
can also be FFRs for mc/cf which in general can be enabled when the
configuration file is generated by defining them at the top of your
.mc file:
define(`_FFR_NAME_HERE', 1)
+----------------------------+
| A BRIEF INTRODUCTION TO M4 |
+----------------------------+
Sendmail uses the M4 macro processor to ``compile'' the configuration
files. The most important thing to know is that M4 is stream-based,
that is, it doesn't understand about lines. For this reason, in some
places you may see the word ``dnl'', which stands for ``delete
through newline''; essentially, it deletes all characters starting
at the ``dnl'' up to and including the next newline character. In
most cases sendmail uses this only to avoid lots of unnecessary
blank lines in the output.
Other important directives are define(A, B) which defines the macro
``A'' to have value ``B''. Macros are expanded as they are read, so
one normally quotes both values to prevent expansion. For example,
define(`SMART_HOST', `smart.foo.com')
One word of warning: M4 macros are expanded even in lines that appear
to be comments. For example, if you have
# See FEATURE(`foo') above
it will not do what you expect, because the FEATURE(`foo') will be
expanded. This also applies to
# And then define the $X macro to be the return address
because ``define'' is an M4 keyword. If you want to use them, surround
them with directed quotes, `like this'.
Since m4 uses single quotes (opening "`" and closing "'") to quote
arguments, those quotes can't be used in arguments. For example,
it is not possible to define a rejection message containing a single
quote. Usually there are simple workarounds by changing those
messages; in the worst case it might be ok to change the value
directly in the generated .cf file, which however is not advised.
Notice:
-------
This package requires a post-V7 version of m4; if you are running the
4.2bsd, SysV.2, or 7th Edition version. SunOS's /usr/5bin/m4 or
BSD-Net/2's m4 both work. GNU m4 version 1.1 or later also works.
Unfortunately, the M4 on BSDI 1.0 doesn't work -- you'll have to use a
Net/2 or GNU version. GNU m4 is available from
ftp://ftp.gnu.org/pub/gnu/m4/m4-1.4.tar.gz (check for the latest version).
EXCEPTIONS: DEC's m4 on Digital UNIX 4.x is broken (3.x is fine). Use GNU
m4 on this platform.
+----------------+
| FILE LOCATIONS |
+----------------+
sendmail 8.9 has introduced a new configuration directory for sendmail
related files, /etc/mail. The new files available for sendmail 8.9 --
the class {R} /etc/mail/relay-domains and the access database
/etc/mail/access -- take advantage of this new directory. Beginning with
8.10, all files will use this directory by default (some options may be
set by OSTYPE() files). This new directory should help to restore
uniformity to sendmail's file locations.
Below is a table of some of the common changes:
Old filename New filename
------------ ------------
/etc/bitdomain /etc/mail/bitdomain
/etc/domaintable /etc/mail/domaintable
/etc/genericstable /etc/mail/genericstable

/usr/lib/sendmail.st /etc/mail/statistics
/usr/ucblib/sendmail.st /etc/mail/statistics
Note that all of these paths actually use a new m4 macro MAIL_SETTINGS_DIR
to create the pathnames. The default value of this variable is
`/etc/mail/'. If you set this macro to a different value, you MUST include
a trailing slash.
Notice: all filenames used in a .mc (or .cf) file should be absolute
(starting at the root, i.e., with '/'). Relative filenames most
likely cause surprises during operations (unless otherwise noted).
+--------+
| OSTYPE |
+--------+
You MUST define an operating system environment, or the configuration
file build will puke. There are several environments available; look
at the "ostype" directory for the current list. This macro changes
things like the location of the alias file and queue directory. Some
of these files are identical to one another.
It is IMPERATIVE that the OSTYPE occur before any MAILER definitions.
In general, the OSTYPE macro should go immediately after any version
information, and MAILER definitions should always go last.
Operating system definitions are usually easy to write. They may define
the following variables (everything defaults, so an ostype file may be
empty). Unfortunately, the list of configuration-supported systems is
not as broad as the list of source-supported systems, since many of
the source contributors do not include corresponding ostype files.
ALIAS_FILE [/etc/mail/aliases] The location of the text version
of the alias file(s). It can be a comma-separated
list of names (but be sure you quote values with
commas in them -- for example, use
define(`ALIAS_FILE', `a,b')
to get "a" and "b" both listed as alias files;
otherwise the define() primitive only sees "a").
HELP_FILE [/etc/mail/helpfile] The name of the file
containing information printed in response to
the SMTP HELP command.
QUEUE_DIR [/var/spool/mqueue] The directory containing
queue files. To use multiple queues, supply
a value ending with an asterisk. For
example, /var/spool/mqueue/qd* will use all of the
directories or symbolic links to directories
beginning with 'qd' in /var/spool/mqueue as queue
directories. The names 'qf', 'df', and 'xf' are
reserved as specific subdirectories for the
corresponding queue file types as explained in
doc/op/op.me. See also QUEUE GROUP DEFINITIONS.
MSP_QUEUE_DIR [/var/spool/clientmqueue] The directory containing
queue files for the MSP (Mail Submission Program,
see sendmail/SECURITY).
STATUS_FILE [/etc/mail/statistics] The file containing status
information.
LOCAL_MAILER_PATH [/bin/mail] The program used to deliver local mail.
LOCAL_MAILER_FLAGS [Prmn9] The flags used by the local mailer. The
flags lsDFMAw5:/|@q are always included.
LOCAL_MAILER_ARGS [mail -d $u] The arguments passed to deliver local
mail.
LOCAL_MAILER_MAX [undefined] If defined, the maximum size of local
mail that you are willing to accept.
LOCAL_MAILER_MAXMSGS [undefined] If defined, the maximum number of
messages to deliver in a single connection. Only
useful for LMTP local mailers.
LOCAL_MAILER_CHARSET [undefined] If defined, messages containing 8-bit data
that ARRIVE from an address that resolves to the
local mailer and which are converted to MIME will be
labeled with this character set.
LOCAL_MAILER_EOL [undefined] If defined, the string to use as the
end of line for the local mailer.
LOCAL_MAILER_DSN_DIAGNOSTIC_CODE
[X-Unix] The DSN Diagnostic-Code value for the
local mailer. This should be changed with care.
LOCAL_SHELL_PATH [/bin/sh] The shell used to deliver piped email.
LOCAL_SHELL_FLAGS [eu9] The flags used by the shell mailer. The
flags lsDFM are always included.
LOCAL_SHELL_ARGS [sh -c $u] The arguments passed to deliver "prog"
mail.
LOCAL_SHELL_DIR [$z:/] The directory search path in which the
shell should run.
LOCAL_MAILER_QGRP [undefined] The queue group for the local mailer.
USENET_MAILER_PATH [/usr/lib/news/inews] The name of the program
used to submit news.
USENET_MAILER_FLAGS [rsDFMmn] The mailer flags for the usenet mailer.
USENET_MAILER_ARGS [-m -h -n] The command line arguments for the
usenet mailer. NOTE: Some versions of inews
(such as those shipped with newer versions of INN)
use different flags. Double check the defaults
against the inews man page.
USENET_MAILER_MAX [undefined] The maximum size of messages that will
be accepted by the usenet mailer.
USENET_MAILER_QGRP [undefined] The queue group for the usenet mailer.
SMTP_MAILER_FLAGS [undefined] Flags added to SMTP mailer. Default
flags are `mDFMuX' for all SMTP-based mailers; the
"esmtp" mailer adds `a'; "smtp8" adds `8'; and
"dsmtp" adds `%'.
RELAY_MAILER_FLAGS [undefined] Flags added to the relay mailer. Default
flags are `mDFMuX' for all SMTP-based mailers; the
relay mailer adds `a8'. If this is not defined,

of the macro Name_MAILER_FLAGS (note: that means Name is entirely in
upper case) and change can be: flags that should be used directly
(thus overriding the default value), or if it starts with `+' (`-')
then those flags are added to (removed from) the default value.
Example:
MODIFY_MAILER_FLAGS(`LOCAL', `+e')
will add the flag `e' to LOCAL_MAILER_FLAGS. Notice: there are
several smtp mailers all of which are manipulated individually.
See the section MAILERS for the available mailer names.
WARNING: The FEATUREs local_lmtp and local_procmail set LOCAL_MAILER_FLAGS
unconditionally, i.e., without respecting any definitions in an
OSTYPE setting.
+---------+
| DOMAINS |
+---------+
You will probably want to collect domain-dependent defines into one
file, referenced by the DOMAIN macro. For example, the Berkeley
domain file includes definitions for several internal distinguished
hosts:
UUCP_RELAY The host that will accept UUCP-addressed email.
If not defined, all UUCP sites must be directly
connected.
BITNET_RELAY The host that will accept BITNET-addressed email.
If not defined, the .BITNET pseudo-domain won't work.
DECNET_RELAY The host that will accept DECNET-addressed email.
If not defined, the .DECNET pseudo-domain and addresses
of the form node::user will not work.
FAX_RELAY The host that will accept mail to the .FAX pseudo-domain.
The "fax" mailer overrides this value.
LOCAL_RELAY The site that will handle unqualified names -- that
is, names without an @domain extension.
Normally MAIL_HUB is preferred for this function.
LOCAL_RELAY is mostly useful in conjunction with
FEATURE(`stickyhost') -- see the discussion of
stickyhost below. If not set, they are assumed to
belong on this machine. This allows you to have a
central site to store a company- or department-wide
alias database. This only works at small sites,
and only with some user agents.
LUSER_RELAY The site that will handle lusers -- that is, apparently
local names that aren't local accounts or aliases. To
specify a local user instead of a site, set this to
``local:username''.
Any of these can be either ``mailer:hostname'' (in which case the
mailer is the internal mailer name, such as ``uucp-new'' and the hostname
is the name of the host as appropriate for that mailer) or just a
``hostname'', in which case a default mailer type (usually ``relay'',
a variant on SMTP) is used. WARNING: if you have a wildcard MX
record matching your domain, you probably want to define these to
have a trailing dot so that you won't get the mail diverted back
to yourself.
The domain file can also be used to define a domain name, if needed
(using "DD<domain>") and set certain site-wide features. If all hosts
at your site masquerade behind one email name, you could also use
MASQUERADE_AS here.
You do not have to define a domain -- in particular, if you are a
single machine sitting off somewhere, it is probably more work than
it's worth. This is just a mechanism for combining "domain dependent
knowledge" into one place.
+---------+
| MAILERS |
+---------+
There are fewer mailers supported in this version than the previous
version, owing mostly to a simpler world. As a general rule, put the
MAILER definitions last in your .mc file.
local The local and prog mailers. You will almost always
need these; the only exception is if you relay ALL
your mail to another site. This mailer is included
automatically.
smtp The Simple Mail Transport Protocol mailer. This does
not hide hosts behind a gateway or another other
such hack; it assumes a world where everyone is
running the name server. This file actually defines
five mailers: "smtp" for regular (old-style) SMTP to
other servers, "esmtp" for extended SMTP to other
servers, "smtp8" to do SMTP to other servers without
converting 8-bit data to MIME (essentially, this is
your statement that you know the other end is 8-bit
clean even if it doesn't say so), "dsmtp" to do on
demand delivery, and "relay" for transmission to the
RELAY_HOST, LUSER_RELAY, or MAIL_HUB.
uucp The UNIX-to-UNIX Copy Program mailer. Actually, this
defines two mailers, "uucp-old" (a.k.a. "uucp") and
"uucp-new" (a.k.a. "suucp"). The latter is for when you
know that the UUCP mailer at the other end can handle
multiple recipients in one transfer. If the smtp mailer
is included in your configuration, two other mailers
("uucp-dom" and "uucp-uudom") are also defined [warning: you
MUST specify MAILER(`smtp') before MAILER(`uucp')]. When you
include the uucp mailer, sendmail looks for all names in
class {U} and sends them to the uucp-old mailer; all
names in class {Y} are sent to uucp-new; and all
names in class {Z} are sent to uucp-uudom. Note that
this is a function of what version of rmail runs on
the receiving end, and hence may be out of your control.
See the section below describing UUCP mailers in more
detail.
usenet Usenet (network news) delivery. If this is specified,
an extra rule is added to ruleset 0 that forwards all
local email for users named ``group.usenet'' to the
``inews'' program. Note that this works for all groups,
and may be considered a security problem.
fax Facsimile transmission. This is experimental and based
on Sam Leffler's HylaFAX software. For more information,
see http://www.hylafax.org/.
pop Post Office Protocol.
procmail An interface to procmail (does not come with sendmail).
This is designed to be used in mailertables. For example,
a common question is "how do I forward all mail for a given
domain to a single person?". If you have this mailer
defined, you could set up a mailertable reading:
host.com procmail:/etc/procmailrcs/host.com
with the file /etc/procmailrcs/host.com reading:
:0 # forward mail for host.com
! -oi -f $1 person@other.host
This would arrange for (anything)@host.com to be sent
to person@other.host. In a procmail script, $1 is the
name of the sender and $2 is the name of the recipient.
If you use this with FEATURE(`local_procmail'), the FEATURE
should be listed first.
Of course there are other ways to solve this particular
problem, e.g., a catch-all entry in a virtusertable.
mail11 The DECnet mail11 mailer, useful only if you have the mail11
program from gatekeeper.dec.com:/pub/DEC/gwtools (and
DECnet, of course). This is for Phase IV DECnet support;
if you have Phase V at your site you may have additional
problems.
phquery The phquery program. This is somewhat counterintuitively
referenced as the "ph" mailer internally. It can be used
to do CCSO name server lookups. The phquery program, which
this mailer uses, is distributed with the ph client.
cyrus The cyrus and cyrusbb mailers. The cyrus mailer delivers to
a local cyrus user. this mailer can make use of the
"user+detail@local.host" syntax (see
FEATURE(`preserve_local_plus_detail')); it will deliver the
mail to the user's "detail" mailbox if the mailbox's ACL
permits. The cyrusbb mailer delivers to a system-wide
cyrus mailbox if the mailbox's ACL permits. The cyrus
mailer must be defined after the local mailer.
cyrusv2 The mailer for Cyrus v2.x. The cyrusv2 mailer delivers to
local cyrus users via LMTP. This mailer can make use of the
"user+detail@local.host" syntax (see
FEATURE(`preserve_local_plus_detail')); it will deliver the
mail to the user's "detail" mailbox if the mailbox's ACL
permits. The cyrusv2 mailer must be defined after the
local mailer.
qpage A mailer for QuickPage, a pager interface. See
http://www.qpage.org/ for further information.
The local mailer accepts addresses of the form "user+detail", where
the "+detail" is not used for mailbox matching but is available
to certain local mail programs (in particular, see
FEATURE(`local_procmail')). For example, "eric", "eric+sendmail", and
"eric+sww" all indicate the same user, but additional arguments <null>,
"sendmail", and "sww" may be provided for use in sorting mail.
+----------+
| FEATURES |
+----------+
Special features can be requested using the "FEATURE" macro. For
example, the .mc line:
FEATURE(`use_cw_file')
tells sendmail that you want to have it read an /etc/mail/local-host-names
file to get values for class {w}. A FEATURE may contain up to 9
optional parameters -- for example:
FEATURE(`mailertable', `dbm /usr/lib/mailertable')
The default database map type for the table features can be set with
define(`DATABASE_MAP_TYPE', `dbm')
which would set it to use ndbm databases. The default is the Berkeley DB
hash database format. Note that you must still declare a database map type
if you specify an argument to a FEATURE. DATABASE_MAP_TYPE is only used
if no argument is given for the FEATURE. It must be specified before any
feature that uses a map.
Also, features which can take a map definition as an argument can also take
the special keyword `LDAP'. If that keyword is used, the map will use the
LDAP definition described in the ``USING LDAP FOR ALIASES, MAPS, AND
CLASSES'' section below.
Available features are:
use_cw_file Read the file /etc/mail/local-host-names file to get
alternate names for this host. This might be used if you
were on a host that MXed for a dynamic set of other hosts.
If the set is static, just including the line "Cw<name1>
<name2> ..." (where the names are fully qualified domain
names) is probably superior. The actual filename can be
overridden by redefining confCW_FILE.
use_ct_file Read the file /etc/mail/trusted-users file to get the
names of users that will be ``trusted'', that is, able to
set their envelope from address using -f without generating
a warning message. The actual filename can be overridden
by redefining confCT_FILE.
redirect Reject all mail addressed to "address.REDIRECT" with
a ``551 User has moved; please try <address>'' message.
If this is set, you can alias people who have left
to their new address with ".REDIRECT" appended.
nouucp Don't route UUCP addresses. This feature takes one
parameter:
`reject': reject addresses which have "!" in the local
part unless it originates from a system
that is allowed to relay.
`nospecial': don't do anything special with "!".
Warnings: 1. See the notice in the anti-spam section.
2. don't remove "!" from OperatorChars if `reject' is
given as parameter.
nopercenthack Don't treat % as routing character. This feature takes one
parameter:
`reject': reject addresses which have % in the local
part unless it originates from a system
that is allowed to relay.
`nospecial': don't do anything special with %.
Warnings: 1. See the notice in the anti-spam section.
2. Don't remove % from OperatorChars if `reject' is
given as parameter.
nocanonify Don't pass addresses to $[ ... $] for canonification
by default, i.e., host/domain names are considered canonical,
except for unqualified names, which must not be used in this
mode (violation of the standard). It can be changed by
setting the DaemonPortOptions modifiers (M=). That is,
FEATURE(`nocanonify') will be overridden by setting the
'c' flag. Conversely, if FEATURE(`nocanonify') is not used,
it can be emulated by setting the 'C' flag
(DaemonPortOptions=Modifiers=C). This would generally only
be used by sites that only act as mail gateways or which have
user agents that do full canonification themselves. You may
also want to use
"define(`confBIND_OPTS', `-DNSRCH -DEFNAMES')" to turn off
the usual resolver options that do a similar thing.
An exception list for FEATURE(`nocanonify') can be
specified with CANONIFY_DOMAIN or CANONIFY_DOMAIN_FILE,
i.e., a list of domains which are nevertheless passed to
$[ ... $] for canonification. This is useful to turn on
canonification for local domains, e.g., use
CANONIFY_DOMAIN(`my.domain my') to canonify addresses
which end in "my.domain" or "my".
Another way to require canonification in the local
domain is CANONIFY_DOMAIN(`$=m').
A trailing dot is added to addresses with more than
one component in it such that other features which
expect a trailing dot (e.g., virtusertable) will
still work.
If `canonify_hosts' is specified as parameter, i.e.,
FEATURE(`nocanonify', `canonify_hosts'), then
addresses which have only a hostname, e.g.,
<user@host>, will be canonified (and hopefully fully
qualified), too.
stickyhost This feature is sometimes used with LOCAL_RELAY,
although it can be used for a different effect with
MAIL_HUB.
When used without MAIL_HUB, email sent to
"user@local.host" are marked as "sticky" -- that
is, the local addresses aren't matched against UDB,
don't go through ruleset 5, and are not forwarded to
the LOCAL_RELAY (if defined).
With MAIL_HUB, mail addressed to "user@local.host"
is forwarded to the mail hub, with the envelope
address still remaining "user@local.host".
Without stickyhost, the envelope would be changed
to "user@mail_hub", in order to protect against
mailing loops.
mailertable Include a "mailer table" which can be used to override
routing for particular domains (which are not in class {w},
i.e. local host names). The argument of the FEATURE may be
the key definition. If none is specified, the definition
used is:
hash /etc/mail/mailertable
Keys in this database are fully qualified domain names
or partial domains preceded by a dot -- for example,
"vangogh.CS.Berkeley.EDU" or ".CS.Berkeley.EDU". As a
special case of the latter, "." matches any domain not
covered by other keys. Values must be of the form:
mailer:domain
where "mailer" is the internal mailer name, and "domain"
is where to send the message. These maps are not
reflected into the message header. As a special case,
the forms:
local:user
will forward to the indicated user using the local mailer,
local:
will forward to the original user in the e-mail address
using the local mailer, and
error:code message
error:D.S.N:code message
will give an error message with the indicated SMTP reply
code and message, where D.S.N is an RFC 1893 compliant
error code.
domaintable Include a "domain table" which can be used to provide
domain name mapping. Use of this should really be
limited to your own domains. It may be useful if you
change names (e.g., your company changes names from
oldname.com to newname.com). The argument of the
FEATURE may be the key definition. If none is specified,
the definition used is:
hash /etc/mail/domaintable
The key in this table is the domain name; the value is
the new (fully qualified) domain. Anything in the
domaintable is reflected into headers; that is, this
is done in ruleset 3.
bitdomain Look up bitnet hosts in a table to try to turn them into
internet addresses. The table can be built using the
bitdomain program contributed by John Gardiner Myers.
The argument of the FEATURE may be the key definition; if
none is specified, the definition used is:
hash /etc/mail/bitdomain
Keys are the bitnet hostname; values are the corresponding
internet hostname.
uucpdomain Similar feature for UUCP hosts. The default map definition
is:
hash /etc/mail/uudomain
At the moment there is no automagic tool to build this
database.
always_add_domain
Include the local host domain even on locally delivered
mail. Normally it is not added on unqualified names.
However, if you use a shared message store but do not use
the same user name space everywhere, you may need the host
name on local names. An optional argument specifies
another domain to be added than the local.
allmasquerade If masquerading is enabled (using MASQUERADE_AS), this
feature will cause recipient addresses to also masquerade
as being from the masquerade host. Normally they get
the local hostname. Although this may be right for
ordinary users, it can break local aliases. For example,
if you send to "localalias", the originating sendmail will
find that alias and send to all members, but send the
message with "To: localalias@masqueradehost". Since that
alias likely does not exist, replies will fail. Use this
feature ONLY if you can guarantee that the ENTIRE
namespace on your masquerade host supersets all the
local entries.
limited_masquerade
Normally, any hosts listed in class {w} are masqueraded. If
this feature is given, only the hosts listed in class {M} (see
below: MASQUERADE_DOMAIN) are masqueraded. This is useful
if you have several domains with disjoint namespaces hosted
on the same machine.
masquerade_entire_domain
If masquerading is enabled (using MASQUERADE_AS) and
MASQUERADE_DOMAIN (see below) is set, this feature will
cause addresses to be rewritten such that the masquerading
domains are actually entire domains to be hidden. All
hosts within the masquerading domains will be rewritten
to the masquerade name (used in MASQUERADE_AS). For example,
if you have:
MASQUERADE_AS(`masq.com')
MASQUERADE_DOMAIN(`foo.org')
MASQUERADE_DOMAIN(`bar.com')
then *foo.org and *bar.com are converted to masq.com. Without
this feature, only foo.org and bar.com are masqueraded.
NOTE: only domains within your jurisdiction and
current hierarchy should be masqueraded using this.
local_no_masquerade
This feature prevents the local mailer from masquerading even
if MASQUERADE_AS is used. MASQUERADE_AS will only have effect
on addresses of mail going outside the local domain.
masquerade_envelope
If masquerading is enabled (using MASQUERADE_AS) or the
genericstable is in use, this feature will cause envelope
addresses to also masquerade as being from the masquerade
host. Normally only the header addresses are masqueraded.
genericstable This feature will cause unqualified addresses (i.e., without
a domain) and addresses with a domain listed in class {G}
to be looked up in a map and turned into another ("generic")
form, which can change both the domain name and the user name.
Notice: if you use an MSP (as it is default starting with
8.12), the MTA will only receive qualified addresses from the
MSP (as required by the RFCs). Hence you need to add your
domain to class {G}. This feature is similar to the userdb
functionality. The same types of addresses as for
masquerading are looked up, i.e., only header sender
addresses unless the allmasquerade and/or masquerade_envelope
features are given. Qualified addresses must have the domain
part in class {G}; entries can be added to this class by the
macros GENERICS_DOMAIN or GENERICS_DOMAIN_FILE (analogously
to MASQUERADE_DOMAIN and MASQUERADE_DOMAIN_FILE, see below).
The argument of FEATURE(`genericstable') may be the map
definition; the default map definition is:
hash /etc/mail/genericstable
The key for this table is either the full address, the domain
(with a leading @; the localpart is passed as first argument)
or the unqualified username (tried in the order mentioned);
the value is the new user address. If the new user address
does not include a domain, it will be qualified in the standard
manner, i.e., using $j or the masquerade name. Note that the
address being looked up must be fully qualified. For local
mail, it is necessary to use FEATURE(`always_add_domain')
for the addresses to be qualified.
The "+detail" of an address is passed as %1, so entries like
old+*@foo.org new+%1@example.com
gen+*@foo.org %1@example.com
and other forms are possible.
generics_entire_domain
If the genericstable is enabled and GENERICS_DOMAIN or
GENERICS_DOMAIN_FILE is used, this feature will cause
addresses to be searched in the map if their domain
parts are subdomains of elements in class {G}.
virtusertable A domain-specific form of aliasing, allowing multiple
virtual domains to be hosted on one machine. For example,
if the virtuser table contains:
info@foo.com foo-info
info@bar.com bar-info
joe@bar.com error:nouser 550 No such user here
jax@bar.com error:5.7.0:550 Address invalid
@baz.org jane@example.net
then mail addressed to info@foo.com will be sent to the
address foo-info, mail addressed to info@bar.com will be
delivered to bar-info, and mail addressed to anyone at baz.org
will be sent to jane@example.net, mail to joe@bar.com will
be rejected with the specified error message, and mail to
jax@bar.com will also have a RFC 1893 compliant error code
5.7.0.
The username from the original address is passed
as %1 allowing:
@foo.org %1@example.com
meaning someone@foo.org will be sent to someone@example.com.
Additionally, if the local part consists of "user+detail"
then "detail" is passed as %2 and "+detail" is passed as %3
when a match against user+* is attempted, so entries like
old+*@foo.org new+%2@example.com
gen+*@foo.org %2@example.com
+*@foo.org %1%3@example.com
X++@foo.org Z%3@example.com
@bar.org %1%3
and other forms are possible. Note: to preserve "+detail"
for a default case (@domain) %1%3 must be used as RHS.
There are two wildcards after "+": "+" matches only a non-empty
detail, "*" matches also empty details, e.g., user+@foo.org
matches +*@foo.org but not ++@foo.org. This can be used
to ensure that the parameters %2 and %3 are not empty.
All the host names on the left hand side (foo.com, bar.com,
and baz.org) must be in class {w} or class {VirtHost}. The
latter can be defined by the macros VIRTUSER_DOMAIN or
VIRTUSER_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
MASQUERADE_DOMAIN_FILE, see below). If VIRTUSER_DOMAIN or
VIRTUSER_DOMAIN_FILE is used, then the entries of class
{VirtHost} are added to class {R}, i.e., relaying is allowed
to (and from) those domains, which by default includes also
all subdomains (see relay_hosts_only). The default map
definition is:
hash /etc/mail/virtusertable
A new definition can be specified as the second argument of
the FEATURE macro, such as
FEATURE(`virtusertable', `dbm /etc/mail/virtusers')
virtuser_entire_domain
If the virtusertable is enabled and VIRTUSER_DOMAIN or
VIRTUSER_DOMAIN_FILE is used, this feature will cause
addresses to be searched in the map if their domain
parts are subdomains of elements in class {VirtHost}.
ldap_routing Implement LDAP-based e-mail recipient routing according to
the Internet Draft draft-lachman-laser-ldap-mail-routing-01.
This provides a method to re-route addresses with a
domain portion in class {LDAPRoute} to either a
different mail host or a different address. Hosts can
be added to this class using LDAPROUTE_DOMAIN and
LDAPROUTE_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
MASQUERADE_DOMAIN_FILE, see below).
See the LDAP ROUTING section below for more information.
nullclient This is a special case -- it creates a configuration file
containing nothing but support for forwarding all mail to a
central hub via a local SMTP-based network. The argument
is the name of that hub.
The only other feature that should be used in conjunction
with this one is FEATURE(`nocanonify'). No mailers
should be defined. No aliasing or forwarding is done.
local_lmtp Use an LMTP capable local mailer. The argument to this
feature is the pathname of an LMTP capable mailer. By
default, mail.local is used. This is expected to be the
mail.local which came with the 8.9 distribution which is
LMTP capable. The path to mail.local is set by the
confEBINDIR m4 variable -- making the default
LOCAL_MAILER_PATH /usr/libexec/mail.local.
If a different LMTP capable mailer is used, its pathname
can be specified as second parameter and the arguments
passed to it (A=) as third parameter, e.g.,
FEATURE(`local_lmtp', `/usr/local/bin/lmtp', `lmtp')
WARNING: This feature sets LOCAL_MAILER_FLAGS unconditionally,
i.e., without respecting any definitions in an OSTYPE setting.
local_procmail Use procmail or another delivery agent as the local mailer.
The argument to this feature is the pathname of the
delivery agent, which defaults to PROCMAIL_MAILER_PATH.
Note that this does NOT use PROCMAIL_MAILER_FLAGS or
PROCMAIL_MAILER_ARGS for the local mailer; tweak
LOCAL_MAILER_FLAGS and LOCAL_MAILER_ARGS instead, or
specify the appropriate parameters. When procmail is used,
the local mailer can make use of the
"user+indicator@local.host" syntax; normally the +indicator
is just tossed, but by default it is passed as the -a
argument to procmail.
This feature can take up to three arguments:
1. Path to the mailer program
[default: /usr/local/bin/procmail]
2. Argument vector including name of the program
[default: procmail -Y -a $h -d $u]
3. Flags for the mailer [default: SPfhn9]
Empty arguments cause the defaults to be taken.
Note that if you are on a system with a broken
setreuid() call, you may need to add -f $f to the procmail
argument vector to pass the proper sender to procmail.
- For example, this allows it to use the maildrop
- (http://www.flounder.net/~mrsam/maildrop/) mailer instead
- by specifying:
+ For example, this allows it to use the maildrop mailer
+ instead by specifying:
FEATURE(`local_procmail', `/usr/local/bin/maildrop',
`maildrop -d $u')
or scanmails using:
FEATURE(`local_procmail', `/usr/local/bin/scanmails')
WARNING: This feature sets LOCAL_MAILER_FLAGS unconditionally,
- i.e., without respecting any definitions in an OSTYPE setting.
+ i.e., without respecting any definitions in an OSTYPE setting.
bestmx_is_local Accept mail as though locally addressed for any host that
lists us as the best possible MX record. This generates
additional DNS traffic, but should be OK for low to
medium traffic hosts. The argument may be a set of
domains, which will limit the feature to only apply to
these domains -- this will reduce unnecessary DNS
traffic. THIS FEATURE IS FUNDAMENTALLY INCOMPATIBLE WITH
WILDCARD MX RECORDS!!! If you have a wildcard MX record
that matches your domain, you cannot use this feature.
smrsh Use the SendMail Restricted SHell (smrsh) provided
with the distribution instead of /bin/sh for mailing
to programs. This improves the ability of the local
system administrator to control what gets run via
e-mail. If an argument is provided it is used as the
pathname to smrsh; otherwise, the path defined by
confEBINDIR is used for the smrsh binary -- by default,
/usr/libexec/smrsh is assumed.
promiscuous_relay
By default, the sendmail configuration files do not permit
mail relaying (that is, accepting mail from outside your
local host (class {w}) and sending it to another host than
your local host). This option sets your site to allow
mail relaying from any site to any site. In almost all
cases, it is better to control relaying more carefully
with the access map, class {R}, or authentication. Domains
can be added to class {R} by the macros RELAY_DOMAIN or
RELAY_DOMAIN_FILE (analogously to MASQUERADE_DOMAIN and
MASQUERADE_DOMAIN_FILE, see below).
relay_entire_domain
This option allows any host in your domain as defined by
class {m} to use your server for relaying. Notice: make
sure that your domain is not just a top level domain,
e.g., com. This can happen if you give your host a name
like example.com instead of host.example.com.
relay_hosts_only
By default, names that are listed as RELAY in the access
db and class {R} are treated as domain names, not host names.
For example, if you specify ``foo.com'', then mail to or
from foo.com, abc.foo.com, or a.very.deep.domain.foo.com
will all be accepted for relaying. This feature changes
the behaviour to look up individual host names only.
relay_based_on_MX
Turns on the ability to allow relaying based on the MX
records of the host portion of an incoming recipient; that
is, if an MX record for host foo.com points to your site,
you will accept and relay mail addressed to foo.com. See
description below for more information before using this
feature. Also, see the KNOWNBUGS entry regarding bestmx
map lookups.
FEATURE(`relay_based_on_MX') does not necessarily allow
routing of these messages which you expect to be allowed,
if route address syntax (or %-hack syntax) is used. If
this is a problem, add entries to the access-table or use
FEATURE(`loose_relay_check').
relay_mail_from
Allows relaying if the mail sender is listed as RELAY in
the access map. If an optional argument `domain' (this
is the literal word `domain', not a placeholder) is given,
relaying can be allowed just based on the domain portion
of the sender address. This feature should only be used if
absolutely necessary as the sender address can be easily
forged. Use of this feature requires the "From:" tag to
be used for the key in the access map; see the discussion
of tags and FEATURE(`relay_mail_from') in the section on
anti-spam configuration control.
relay_local_from
Allows relaying if the domain portion of the mail sender
is a local host. This should only be used if absolutely
necessary as it opens a window for spammers. Specifically,
they can send mail to your mail server that claims to be
from your domain (either directly or via a routed address),
and you will go ahead and relay it out to arbitrary hosts
on the Internet.
accept_unqualified_senders
Normally, MAIL FROM: commands in the SMTP session will be
refused if the connection is a network connection and the
sender address does not include a domain name. If your
setup sends local mail unqualified (i.e., MAIL FROM:<joe>),
you will need to use this feature to accept unqualified
sender addresses. Setting the DaemonPortOptions modifier
'u' overrides the default behavior, i.e., unqualified
addresses are accepted even without this FEATURE.
If this FEATURE is not used, the DaemonPortOptions modifier
'f' can be used to enforce fully qualified addresses.
accept_unresolvable_domains
Normally, MAIL FROM: commands in the SMTP session will be
refused if the host part of the argument to MAIL FROM:
cannot be located in the host name service (e.g., an A or
MX record in DNS). If you are inside a firewall that has
only a limited view of the Internet host name space, this
could cause problems. In this case you probably want to
use this feature to accept all domains on input, even if
they are unresolvable.
access_db Turns on the access database feature. The access db gives
you the ability to allow or refuse to accept mail from
specified domains for administrative reasons. Moreover,
it can control the behavior of sendmail in various situations.
By default, the access database specification is:
hash -T<TMPF> /etc/mail/access
See the anti-spam configuration control section for further
important information about this feature. Notice:
"-T<TMPF>" is meant literal, do not replace it by anything.
blocklist_recipients
Turns on the ability to block incoming mail for certain
recipient usernames, hostnames, or addresses. For
example, you can block incoming mail to user nobody,
host foo.mydomain.com, or guest@bar.mydomain.com.
These specifications are put in the access db as
described in the anti-spam configuration control section
later in this document.
delay_checks The rulesets check_mail and check_relay will not be called
when a client connects or issues a MAIL command, respectively.
Instead, those rulesets will be called by the check_rcpt
ruleset; they will be skipped under certain circumstances.
See "Delay all checks" in the anti-spam configuration control
section. Note: this feature is incompatible to the versions
in 8.10 and 8.11.
+check_other Enable a default check_other ruleset which terminates
+ an SMTP session when it encounters a command which matches
+ a regular expression given as argument. If no argument
+ is given, then the default (to match potential headers) is:
+ ^[[:print:]]+ *:
+
use_client_ptr If this feature is enabled then check_relay will override
its first argument with $&{client_ptr}. This is useful for
rejections based on the unverified hostname of client,
which turns on the same behavior as in earlier sendmail
versions when delay_checks was not in use. See doc/op/op.*
about check_relay, {client_name}, and {client_ptr}.
dnsbl Turns on rejection, discarding, or quarantining of hosts
found in a DNS based list. The first argument is used as
the domain in which blocked hosts are listed. A second
argument can be used to change the default error message,
or select one of the operations `discard' and `quarantine'.
Without that second argument, the error message will be
Rejected: IP-ADDRESS listed at SERVER
where IP-ADDRESS and SERVER are replaced by the appropriate
information. By default, temporary lookup failures are
ignored. This behavior can be changed by specifying a
third argument, which must be either `t' or a full error
message. See the anti-spam configuration control section for
an example. The dnsbl feature can be included several times
to query different DNS based rejection lists. See also
enhdnsbl for an enhanced version.
Set the DNSBL_MAP mc option to change the default map
definition from `host'. Set the DNSBL_MAP_OPT mc option
to add additional options to the map specification used.
Some DNS based rejection lists cause failures if asked
for AAAA records. If your sendmail version is compiled
with IPv6 support (NETINET6) and you experience this
problem, add
define(`DNSBL_MAP', `dns -R A')
before the first use of this feature. Alternatively you
can use enhdnsbl instead (see below). Moreover, this
statement can be used to reduce the number of DNS retries,
e.g.,
define(`DNSBL_MAP', `dns -R A -r2')
See below (EDNSBL_TO) for an explanation.
enhdnsbl Enhanced version of dnsbl (see above). Further arguments
(up to 5) can be used to specify specific return values
from lookups. Temporary lookup failures are ignored unless
a third argument is given, which must be either `t' or a full
error message. By default, any successful lookup will
generate an error. Otherwise the result of the lookup is
compared with the supplied argument(s), and only if a match
occurs an error is generated. For example,
FEATURE(`enhdnsbl', `dnsbl.example.com', `', `t', `127.0.0.2.')
will reject the e-mail if the lookup returns the value
``127.0.0.2.'', or generate a 451 response if the lookup
temporarily failed. The arguments can contain metasymbols
as they are allowed in the LHS of rules. As the example
shows, the default values are also used if an empty argument,
i.e., `', is specified. This feature requires that sendmail
has been compiled with the flag DNSMAP (see sendmail/README).
Set the EDNSBL_TO mc option to change the DNS retry count
from the default value of 5, this can be very useful when
a DNS server is not responding, which in turn may cause
clients to time out (an entry stating
did not issue MAIL/EXPN/VRFY/ETRN
will be logged).
ratecontrol Enable simple ruleset to do connection rate control
checking. This requires entries in access_db of the form
ClientRate:IP.ADD.RE.SS LIMIT
The RHS specifies the maximum number of connections
(an integer number) over the time interval defined
by ConnectionRateWindowSize, where 0 means unlimited.
Take the following example:
ClientRate:10.1.2.3 4
ClientRate:127.0.0.1 0
ClientRate: 10
10.1.2.3 can only make up to 4 connections, the
general limit it 10, and 127.0.0.1 can make an unlimited
number of connections per ConnectionRateWindowSize.
See also CONNECTION CONTROL.
conncontrol Enable a simple check of the number of incoming SMTP
connections. This requires entries in access_db of the
form
ClientConn:IP.ADD.RE.SS LIMIT
The RHS specifies the maximum number of open connections
(an integer number).
Take the following example:
ClientConn:10.1.2.3 4
ClientConn:127.0.0.1 0
ClientConn: 10
10.1.2.3 can only have up to 4 open connections, the
general limit it 10, and 127.0.0.1 does not have any
explicit limit.
See also CONNECTION CONTROL.
mtamark Experimental support for "Marking Mail Transfer Agents in
Reverse DNS with TXT RRs" (MTAMark), see
draft-stumpf-dns-mtamark-01. Optional arguments are:
1. Error message, default:
550 Rejected: $&{client_addr} not listed as MTA
2. Temporary lookup failures are ignored unless a second
argument is given, which must be either `t' or a full
error message.
3. Lookup prefix, default: _perm._smtp._srv. This should
not be changed unless the draft changes it.
Example:
FEATURE(`mtamark', `', `t')
lookupdotdomain Look up also .domain in the access map. This allows to
match only subdomains. It does not work well with
FEATURE(`relay_hosts_only'), because most lookups for
subdomains are suppressed by the latter feature.
loose_relay_check
Normally, if % addressing is used for a recipient, e.g.
user%site@othersite, and othersite is in class {R}, the
check_rcpt ruleset will strip @othersite and recheck
user@site for relaying. This feature changes that
behavior. It should not be needed for most installations.
authinfo Provide a separate map for client side authentication
information. See SMTP AUTHENTICATION for details.
By default, the authinfo database specification is:
hash /etc/mail/authinfo
preserve_luser_host
Preserve the name of the recipient host if LUSER_RELAY is
used. Without this option, the domain part of the
recipient address will be replaced by the host specified as
LUSER_RELAY. This feature only works if the hostname is
passed to the mailer (see mailer triple in op.me). Note
that in the default configuration the local mailer does not
receive the hostname, i.e., the mailer triple has an empty
hostname.
preserve_local_plus_detail
Preserve the +detail portion of the address when passing
address to local delivery agent. Disables alias and
.forward +detail stripping (e.g., given user+detail, only
that address will be looked up in the alias file; user+* and
user will not be looked up). Only use if the local
delivery agent in use supports +detail addressing.
Moreover, this will most likely not work if the 'w' flag
for the local mailer is set as the entire local address
including +detail is passed to the user lookup function.
compat_check Enable ruleset check_compat to look up pairs of addresses
with the Compat: tag -- Compat:sender<@>recipient -- in the
access map. Valid values for the RHS include
DISCARD silently discard recipient
TEMP: return a temporary error
ERROR: return a permanent error
In the last two cases, a 4xy/5xy SMTP reply code should
follow the colon.
no_default_msa Don't generate the default MSA daemon, i.e.,
DAEMON_OPTIONS(`Port=587,Name=MSA,M=E')
To define a MSA daemon with other parameters, use this
FEATURE and introduce new settings via DAEMON_OPTIONS().
msp Defines config file for Message Submission Program.
See sendmail/SECURITY for details and cf/cf/submit.mc how
to use it. An optional argument can be used to override
the default of `[localhost]' to use as host to send all
e-mails to. Note that MX records will be used if the
specified hostname is not in square brackets (e.g.,
[hostname]). If `MSA' is specified as second argument then
port 587 is used to contact the server. Example:
FEATURE(`msp', `', `MSA')
Some more hints about possible changes can be found below
in the section MESSAGE SUBMISSION PROGRAM.
Note: Due to many problems, submit.mc uses
FEATURE(`msp', `[127.0.0.1]')
by default. If you have a machine with IPv6 only,
change it to
FEATURE(`msp', `[IPv6:0:0:0:0:0:0:0:1]')
If you want to continue using '[localhost]', (the behavior
up to 8.12.6), use
FEATURE(`msp')
queuegroup A simple example how to select a queue group based
on the full e-mail address or the domain of the
recipient. Selection is done via entries in the
access map using the tag QGRP:, for example:
QGRP:example.com main
QGRP:friend@some.org others
QGRP:my.domain local
where "main", "others", and "local" are names of
queue groups. If an argument is specified, it is used
as default queue group.
Note: please read the warning in doc/op/op.me about
queue groups and possible queue manipulations.
greet_pause Adds the greet_pause ruleset which enables open proxy
and SMTP slamming protection. The feature can take an
argument specifying the milliseconds to wait:
FEATURE(`greet_pause', `5000') dnl 5 seconds
If FEATURE(`access_db') is enabled, an access database
lookup with the GreetPause tag is done using client
hostname, domain, IP address, or subnet to determine the
pause time:
GreetPause:my.domain 0
GreetPause:example.com 5000
GreetPause:10.1.2 2000
GreetPause:127.0.0.1 0
When using FEATURE(`access_db'), the optional
FEATURE(`greet_pause') argument becomes the default if
nothing is found in the access database. A ruleset called
Local_greet_pause can be used for local modifications, e.g.,
LOCAL_RULESETS
SLocal_greet_pause
R$* $: $&{daemon_flags}
R$* a $* $# 0
block_bad_helo Reject messages from SMTP clients which provide a HELO/EHLO
argument which is either unqualified, or is one of our own
names (i.e., the server name instead of the client name).
This check is performed at RCPT stage and disabled for the
following cases:
- authenticated sessions,
- connections from IP addresses in class $={R}.
Currently access_db lookups can not be used to
(selectively) disable this test, moreover,
FEATURE(`delay_checks')
is required. Note, the block_bad_helo feature automatically
adds the IPv6 and IPv4 localhost IP addresses to $={w} (local
host names) and $={R} (relay permitted).
require_rdns Reject mail from connecting SMTP clients without proper
rDNS (reverse DNS), functional gethostbyaddr() resolution.
Note: this feature will cause false positives, i.e., there
are legitimate MTAs that do not have proper DNS entries.
Rejecting mails from those MTAs is a local policy decision.
The basic policy is to reject message with a 5xx error if
the IP address fails to resolve. However, if this is a
temporary failure, a 4xx temporary failure is returned.
If the look-up succeeds, but returns an apparently forged
value, this is treated as a temporary failure with a 4xx
error code.
EXCEPTIONS:
Exceptions based on access entries are discussed below.
Any IP address matched using $=R (the "relay-domains" file)
is excepted from the rules. Since we have explicitly
allowed relaying for this host, based on IP address, we
ignore the rDNS failure.
The philosophical assumption here is that most users do
not control their rDNS. They should be able to send mail
through their ISP, whether or not they have valid rDNS.
The class $=R, roughly speaking, contains those IP addresses
and address ranges for which we are the ISP, or are acting
as if the ISP.
If `delay_checks' is in effect (recommended), then any
sender who has authenticated is also excepted from the
restrictions. This happens because the rules produced by
this FEATURE() will not be applied to authenticated senders
(assuming `delay_checks').
ACCESS MAP ENTRIES:
Entries such as
Connect:1.2.3.4 OK
- Connect:1.2 RELAY
- will allowlist IP address 1.2.3.4, so that the rDNS
- blocking does apply to that IP address
+ Connect:1.3 RELAY
+ will allowlist IP address 1.2.3.4 and IP net 1.3.*
+ so that the rDNS blocking does apply not to those IPs.
Entries such as
Connect:1.2.3.4 REJECT
will have the effect of forcing a temporary failure for
that address to be treated as a permanent failure.
badmx Reject envelope sender addresses (MAIL) whose domain part
resolves to a "bad" MX record. By default these are
MX records which resolve to A records that match the
regular expression:
^(127\.|10\.|0\.0\.0\.0)
This default regular expression can be overridden by
specifying an argument, e.g.,
FEATURE(`badmx', `^127\.0\.0\.1')
Note: this feature requires that the sendmail binary
has been compiled with the options MAP_REGEX and
DNSMAP.
+sts Experimental support for Strict Transport Security
+ (MTA-STS, see RFC 8461). It sets the option
+ StrictTransportSecurity and takes one optional
+ argument: the socket map specification to access
+ postfix-mta-sts-resolver (see feature/sts.m4
+ for the default value).
+ For more information see doc/op/op.me.

| HACKS |
+-------+
Some things just can't be called features. To make this clear,
they go in the hack subdirectory and are referenced using the HACK
macro. These will tend to be site-dependent. The release
includes the Berkeley-dependent "cssubdomain" hack (that makes
sendmail accept local names in either Berkeley.EDU or CS.Berkeley.EDU;
this is intended as a short-term aid while moving hosts into
subdomains.
+--------------------+
| SITE CONFIGURATION |
+--------------------+
*****************************************************
* This section is really obsolete, and is preserved *
* only for back compatibility. You should plan on *
* using mailertables for new installations. In *
* particular, it doesn't work for the newer forms *
* of UUCP mailers, such as uucp-uudom. *
*****************************************************
Complex sites will need more local configuration information, such as
lists of UUCP hosts they speak with directly. This can get a bit more
tricky. For an example of a "complex" site, see cf/ucbvax.mc.
The SITECONFIG macro allows you to indirectly reference site-dependent
configuration information stored in the siteconfig subdirectory. For
example, the line
SITECONFIG(`uucp.ucbvax', `ucbvax', `U')
reads the file uucp.ucbvax for local connection information. The
second parameter is the local name (in this case just "ucbvax" since
it is locally connected, and hence a UUCP hostname). The third
parameter is the name of both a macro to store the local name (in
this case, {U}) and the name of the class (e.g., {U}) in which to store
the host information read from the file. Another SITECONFIG line reads
SITECONFIG(`uucp.ucbarpa', `ucbarpa.Berkeley.EDU', `W')
This says that the file uucp.ucbarpa contains the list of UUCP sites
connected to ucbarpa.Berkeley.EDU. Class {W} will be used to
store this list, and $W is defined to be ucbarpa.Berkeley.EDU, that
is, the name of the relay to which the hosts listed in uucp.ucbarpa
are connected. [The machine ucbarpa is gone now, but this
out-of-date configuration file has been left around to demonstrate
how you might do this.]
Note that the case of SITECONFIG with a third parameter of ``U'' is
special; the second parameter is assumed to be the UUCP name of the
local site, rather than the name of a remote site, and the UUCP name
is entered into class {w} (the list of local hostnames) as $U.UUCP.
The siteconfig file (e.g., siteconfig/uucp.ucbvax.m4) contains nothing
more than a sequence of SITE macros describing connectivity. For
example:
SITE(`cnmat')
SITE(`sgi olympus')
The second example demonstrates that you can use two names on the
same line; these are usually aliases for the same host (or are at
least in the same company).
The macro LOCAL_UUCP can be used to add rules into the generated
cf file at the place where MAILER(`uucp') inserts its rules. This
should only be used if really necessary.
+--------------------+
| USING UUCP MAILERS |
+--------------------+
It's hard to get UUCP mailers right because of the extremely ad hoc
nature of UUCP addressing. These config files are really designed
for domain-based addressing, even for UUCP sites.
There are four UUCP mailers available. The choice of which one to
use is partly a matter of local preferences and what is running at
the other end of your UUCP connection. Unlike good protocols that
define what will go over the wire, UUCP uses the policy that you
should do what is right for the other end; if they change, you have
to change. This makes it hard to do the right thing, and discourages
people from updating their software. In general, if you can avoid
UUCP, please do.
The major choice is whether to go for a domainized scheme or a
non-domainized scheme. This depends entirely on what the other
end will recognize. If at all possible, you should encourage the
other end to go to a domain-based system -- non-domainized addresses
don't work entirely properly.
The four mailers are:
uucp-old (obsolete name: "uucp")
This is the oldest, the worst (but the closest to UUCP) way of
sending messages across UUCP connections. It does bangify
everything and prepends $U (your UUCP name) to the sender's
address (which can already be a bang path itself). It can
only send to one address at a time, so it spends a lot of
time copying duplicates of messages. Avoid this if at all
possible.
uucp-new (obsolete name: "suucp")
The same as above, except that it assumes that in one rmail
command you can specify several recipients. It still has a
lot of other problems.
uucp-dom
This UUCP mailer keeps everything as domain addresses.
Basically, it uses the SMTP mailer rewriting rules. This mailer
is only included if MAILER(`smtp') is specified before
MAILER(`uucp').
Unfortunately, a lot of UUCP mailer transport agents require
bangified addresses in the envelope, although you can use
domain-based addresses in the message header. (The envelope
shows up as the From_ line on UNIX mail.) So....
uucp-uudom
This is a cross between uucp-new (for the envelope addresses)
and uucp-dom (for the header addresses). It bangifies the
envelope sender (From_ line in messages) without adding the
local hostname, unless there is no host name on the address
at all (e.g., "wolf") or the host component is a UUCP host name
instead of a domain name ("somehost!wolf" instead of
"some.dom.ain!wolf"). This is also included only if MAILER(`smtp')
is also specified earlier.
Examples:
On host grasp.insa-lyon.fr (UUCP host name "grasp"), the following
summarizes the sender rewriting for various mailers.
Mailer sender rewriting in the envelope
------ ------ -------------------------
uucp-{old,new} wolf grasp!wolf
uucp-dom wolf wolf@grasp.insa-lyon.fr
uucp-uudom wolf grasp.insa-lyon.fr!wolf
uucp-{old,new} wolf@fr.net grasp!fr.net!wolf
uucp-dom wolf@fr.net wolf@fr.net
uucp-uudom wolf@fr.net fr.net!wolf
uucp-{old,new} somehost!wolf grasp!somehost!wolf
uucp-dom somehost!wolf somehost!wolf@grasp.insa-lyon.fr
uucp-uudom somehost!wolf grasp.insa-lyon.fr!somehost!wolf
If you are using one of the domainized UUCP mailers, you really want
to convert all UUCP addresses to domain format -- otherwise, it will
do it for you (and probably not the way you expected). For example,
if you have the address foo!bar!baz (and you are not sending to foo),
the heuristics will add the @uucp.relay.name or @local.host.name to
this address. However, if you map foo to foo.host.name first, it
will not add the local hostname. You can do this using the uucpdomain
feature.
+-------------------+
| TWEAKING RULESETS |
+-------------------+
For more complex configurations, you can define special rules.
The macro LOCAL_RULE_3 introduces rules that are used in canonicalizing
the names. Any modifications made here are reflected in the header.
A common use is to convert old UUCP addresses to SMTP addresses using
the UUCPSMTP macro. For example:
LOCAL_RULE_3
UUCPSMTP(`decvax', `decvax.dec.com')
UUCPSMTP(`research', `research.att.com')
will cause addresses of the form "decvax!user" and "research!user"
to be converted to "user@decvax.dec.com" and "user@research.att.com"
respectively.
This could also be used to look up hosts in a database map:
LOCAL_RULE_3
R$* < @ $+ > $* $: $1 < @ $(hostmap $2 $) > $3
This map would be defined in the LOCAL_CONFIG portion, as shown below.
Similarly, LOCAL_RULE_0 can be used to introduce new parsing rules.
For example, new rules are needed to parse hostnames that you accept
via MX records. For example, you might have:
LOCAL_RULE_0
R$+ <@ host.dom.ain.> $#uucp $@ cnmat $: $1 < @ host.dom.ain.>
You would use this if you had installed an MX record for cnmat.Berkeley.EDU
pointing at this host; this rule catches the message and forwards it on
using UUCP.
You can also tweak rulesets 1 and 2 using LOCAL_RULE_1 and LOCAL_RULE_2.
These rulesets are normally empty.
A similar macro is LOCAL_CONFIG. This introduces lines added after the
boilerplate option setting but before rulesets. Do not declare rulesets in
the LOCAL_CONFIG section. It can be used to declare local database maps or
whatever. For example:
LOCAL_CONFIG
Khostmap hash /etc/mail/hostmap
Kyplocal nis -m hosts.byname
+---------------------------+
| MASQUERADING AND RELAYING |
+---------------------------+
You can have your host masquerade as another using
MASQUERADE_AS(`host.domain')
This causes mail being sent to be labeled as coming from the
indicated host.domain, rather than $j. One normally masquerades as
one of one's own subdomains (for example, it's unlikely that
Berkeley would choose to masquerade as an MIT site). This
behaviour is modified by a plethora of FEATUREs; in particular, see
masquerade_envelope, allmasquerade, limited_masquerade, and
masquerade_entire_domain.
The masquerade name is not normally canonified, so it is important
that it be your One True Name, that is, fully qualified and not a
CNAME. However, if you use a CNAME, the receiving side may canonify
it for you, so don't think you can cheat CNAME mapping this way.
Normally the only addresses that are masqueraded are those that come
from this host (that is, are either unqualified or in class {w}, the list
of local domain names). You can augment this list, which is realized
by class {M} using
MASQUERADE_DOMAIN(`otherhost.domain')
The effect of this is that although mail to user@otherhost.domain
will not be delivered locally, any mail including any user@otherhost.domain
will, when relayed, be rewritten to have the MASQUERADE_AS address.
This can be a space-separated list of names.
If these names are in a file, you can use
MASQUERADE_DOMAIN_FILE(`filename')
to read the list of names from the indicated file (i.e., to add
elements to class {M}).
To exempt hosts or subdomains from being masqueraded, you can use
MASQUERADE_EXCEPTION(`host.domain')
This can come handy if you want to masquerade a whole domain
except for one (or a few) host(s). If these names are in a file,
you can use
MASQUERADE_EXCEPTION_FILE(`filename')
Normally only header addresses are masqueraded. If you want to
masquerade the envelope as well, use
FEATURE(`masquerade_envelope')
There are always users that need to be "exposed" -- that is, their
internal site name should be displayed instead of the masquerade name.
Root is an example (which has been "exposed" by default prior to 8.10).
You can add users to this list using
EXPOSED_USER(`usernames')
This adds users to class {E}; you could also use
EXPOSED_USER_FILE(`filename')
You can also arrange to relay all unqualified names (that is, names
without @host) to a relay host. For example, if you have a central
email server, you might relay to that host so that users don't have
to have .forward files or aliases. You can do this using
define(`LOCAL_RELAY', `mailer:hostname')
The ``mailer:'' can be omitted, in which case the mailer defaults to
"relay". There are some user names that you don't want relayed, perhaps
because of local aliases. A common example is root, which may be
locally aliased. You can add entries to this list using
LOCAL_USER(`usernames')
This adds users to class {L}; you could also use
LOCAL_USER_FILE(`filename')
If you want all incoming mail sent to a centralized hub, as for a
shared /var/spool/mail scheme, use
define(`MAIL_HUB', `mailer:hostname')
Again, ``mailer:'' defaults to "relay". If you define both LOCAL_RELAY
and MAIL_HUB _AND_ you have FEATURE(`stickyhost'), unqualified names will
be sent to the LOCAL_RELAY and other local names will be sent to MAIL_HUB.
Note: there is a (long standing) bug which keeps this combination from
working for addresses of the form user+detail.
Names in class {L} will be delivered locally, so you MUST have aliases or
.forward files for them.
For example, if you are on machine mastodon.CS.Berkeley.EDU and you have
FEATURE(`stickyhost'), the following combinations of settings will have the
indicated effects:
email sent to.... eric eric@mastodon.CS.Berkeley.EDU
LOCAL_RELAY set to mail.CS.Berkeley.EDU (delivered locally)
mail.CS.Berkeley.EDU (no local aliasing) (aliasing done)
MAIL_HUB set to mammoth.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU
mammoth.CS.Berkeley.EDU (aliasing done) (aliasing done)
Both LOCAL_RELAY and mail.CS.Berkeley.EDU mammoth.CS.Berkeley.EDU
MAIL_HUB set as above (no local aliasing) (aliasing done)
If you do not have FEATURE(`stickyhost') set, then LOCAL_RELAY and
MAIL_HUB act identically, with MAIL_HUB taking precedence.
If you want all outgoing mail to go to a central relay site, define
SMART_HOST as well. Briefly:
LOCAL_RELAY applies to unqualified names (e.g., "eric").
MAIL_HUB applies to names qualified with the name of the
local host (e.g., "eric@mastodon.CS.Berkeley.EDU").
SMART_HOST applies to names qualified with other hosts or
bracketed addresses (e.g., "eric@mastodon.CS.Berkeley.EDU"
or "eric@[127.0.0.1]").
However, beware that other relays (e.g., UUCP_RELAY, BITNET_RELAY,
DECNET_RELAY, and FAX_RELAY) take precedence over SMART_HOST, so if you
really want absolutely everything to go to a single central site you will
need to unset all the other relays -- or better yet, find or build a
minimal config file that does this.
For duplicate suppression to work properly, the host name is best
specified with a terminal dot:
define(`MAIL_HUB', `host.domain.')
note the trailing dot ---^
+-------------------------------------------+
| USING LDAP FOR ALIASES, MAPS, AND CLASSES |
+-------------------------------------------+
LDAP can be used for aliases, maps, and classes by either specifying your
own LDAP map specification or using the built-in default LDAP map
specification. The built-in default specifications all provide lookups
which match against either the machine's fully qualified hostname (${j}) or
a "cluster". The cluster allows you to share LDAP entries among a large
number of machines without having to enter each of the machine names into
each LDAP entry. To set the LDAP cluster name to use for a particular
machine or set of machines, set the confLDAP_CLUSTER m4 variable to a
unique name. For example:
define(`confLDAP_CLUSTER', `Servers')
Here, the word `Servers' will be the cluster name. As an example, assume
that smtp.sendmail.org, etrn.sendmail.org, and mx.sendmail.org all belong
to the Servers cluster.
Some of the LDAP LDIF examples below show use of the Servers cluster.
Every entry must have either a sendmailMTAHost or sendmailMTACluster
attribute or it will be ignored. Be careful as mixing clusters and
individual host records can have surprising results (see the CAUTION
sections below).
See the file cf/sendmail.schema for the actual LDAP schemas. Note that
this schema (and therefore the lookups and examples below) is experimental
at this point as it has had little public review. Therefore, it may change
in future versions. Feedback via sendmail-YYYY@support.sendmail.org is
encouraged (replace YYYY with the current year, e.g., 2005).
-------
Aliases
-------
The ALIAS_FILE (O AliasFile) option can be set to use LDAP for alias
lookups. To use the default schema, simply use:
define(`ALIAS_FILE', `ldap:')
By doing so, you will use the default schema which expands to a map
declared as follows:
ldap -k (&(objectClass=sendmailMTAAliasObject)
(sendmailMTAAliasGrouping=aliases)
(|(sendmailMTACluster=${sendmailMTACluster})
(sendmailMTAHost=$j))
(sendmailMTAKey=%0))
-v sendmailMTAAliasValue,sendmailMTAAliasSearch:FILTER:sendmailMTAAliasObject,sendmailMTAAliasURL:URL:sendmailMTAAliasObject
NOTE: The macros shown above ${sendmailMTACluster} and $j are not actually
used when the binary expands the `ldap:' token as the AliasFile option is
not actually macro-expanded when read from the sendmail.cf file.
Example LDAP LDIF entries might be:
dn: sendmailMTAKey=sendmail-list, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAAlias
objectClass: sendmailMTAAliasObject
sendmailMTAAliasGrouping: aliases
sendmailMTAHost: etrn.sendmail.org
sendmailMTAKey: sendmail-list
sendmailMTAAliasValue: ca@example.org
sendmailMTAAliasValue: eric
sendmailMTAAliasValue: gshapiro@example.com
dn: sendmailMTAKey=owner-sendmail-list, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAAlias
objectClass: sendmailMTAAliasObject
sendmailMTAAliasGrouping: aliases
sendmailMTAHost: etrn.sendmail.org
sendmailMTAKey: owner-sendmail-list
sendmailMTAAliasValue: eric
dn: sendmailMTAKey=postmaster, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAAlias
objectClass: sendmailMTAAliasObject
sendmailMTAAliasGrouping: aliases
sendmailMTACluster: Servers
sendmailMTAKey: postmaster
sendmailMTAAliasValue: eric
Here, the aliases sendmail-list and owner-sendmail-list will be available
only on etrn.sendmail.org but the postmaster alias will be available on
every machine in the Servers cluster (including etrn.sendmail.org).
CAUTION: aliases are additive so that entries like these:
dn: sendmailMTAKey=bob, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAAlias
objectClass: sendmailMTAAliasObject
sendmailMTAAliasGrouping: aliases
sendmailMTACluster: Servers
sendmailMTAKey: bob
sendmailMTAAliasValue: eric
dn: sendmailMTAKey=bobetrn, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAAlias
objectClass: sendmailMTAAliasObject
sendmailMTAAliasGrouping: aliases
sendmailMTAHost: etrn.sendmail.org
sendmailMTAKey: bob
sendmailMTAAliasValue: gshapiro
would mean that on all of the hosts in the cluster, mail to bob would go to
eric EXCEPT on etrn.sendmail.org in which case it would go to BOTH eric and
gshapiro.
If you prefer not to use the default LDAP schema for your aliases, you can
specify the map parameters when setting ALIAS_FILE. For example:
define(`ALIAS_FILE', `ldap:-k (&(objectClass=mailGroup)(mail=%0)) -v mgrpRFC822MailMember')
----
Maps
----
FEATURE()'s which take an optional map definition argument (e.g., access,
mailertable, virtusertable, etc.) can instead take the special keyword
`LDAP', e.g.:
FEATURE(`access_db', `LDAP')
FEATURE(`virtusertable', `LDAP')
When this keyword is given, that map will use LDAP lookups consisting of
the objectClass sendmailMTAClassObject, the attribute sendmailMTAMapName
with the map name, a search attribute of sendmailMTAKey, and the value
attribute sendmailMTAMapValue.
The values for sendmailMTAMapName are:
FEATURE() sendmailMTAMapName
--------- ------------------
access_db access
authinfo authinfo
bitdomain bitdomain
domaintable domain
genericstable generics
mailertable mailer
uucpdomain uucpdomain
virtusertable virtuser
For example, FEATURE(`mailertable', `LDAP') would use the map definition:
Kmailertable ldap -k (&(objectClass=sendmailMTAMapObject)
(sendmailMTAMapName=mailer)
(|(sendmailMTACluster=${sendmailMTACluster})
(sendmailMTAHost=$j))
(sendmailMTAKey=%0))
-1 -v sendmailMTAMapValue,sendmailMTAMapSearch:FILTER:sendmailMTAMapObject,sendmailMTAMapURL:URL:sendmailMTAMapObject
An example LDAP LDIF entry using this map might be:
dn: sendmailMTAMapName=mailer, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAMap
sendmailMTACluster: Servers
sendmailMTAMapName: mailer
dn: sendmailMTAKey=example.com, sendmailMTAMapName=mailer, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAMap
objectClass: sendmailMTAMapObject
sendmailMTAMapName: mailer
sendmailMTACluster: Servers
sendmailMTAKey: example.com
sendmailMTAMapValue: relay:[smtp.example.com]
CAUTION: If your LDAP database contains the record above and *ALSO* a host
specific record such as:
dn: sendmailMTAKey=example.com@etrn, sendmailMTAMapName=mailer, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAMap
objectClass: sendmailMTAMapObject
sendmailMTAMapName: mailer
sendmailMTAHost: etrn.sendmail.org
sendmailMTAKey: example.com
sendmailMTAMapValue: relay:[mx.example.com]
then these entries will give unexpected results. When the lookup is done
on etrn.sendmail.org, the effect is that there is *NO* match at all as maps
require a single match. Since the host etrn.sendmail.org is also in the
Servers cluster, LDAP would return two answers for the example.com map key
in which case sendmail would treat this as no match at all.
If you prefer not to use the default LDAP schema for your maps, you can
specify the map parameters when using the FEATURE(). For example:
FEATURE(`access_db', `ldap:-1 -k (&(objectClass=mapDatabase)(key=%0)) -v value')
-------
Classes
-------
Normally, classes can be filled via files or programs. As of 8.12, they
can also be filled via map lookups using a new syntax:
F{ClassName}mapkey@mapclass:mapspec
mapkey is optional and if not provided the map key will be empty. This can
be used with LDAP to read classes from LDAP. Note that the lookup is only
done when sendmail is initially started. Use the special value `@LDAP' to
use the default LDAP schema. For example:
RELAY_DOMAIN_FILE(`@LDAP')
would put all of the attribute sendmailMTAClassValue values of LDAP records
with objectClass sendmailMTAClass and an attribute sendmailMTAClassName of
'R' into class $={R}. In other words, it is equivalent to the LDAP map
specification:
F{R}@ldap:-k (&(objectClass=sendmailMTAClass)
(sendmailMTAClassName=R)
(|(sendmailMTACluster=${sendmailMTACluster})
(sendmailMTAHost=$j)))
-v sendmailMTAClassValue,sendmailMTAClassSearch:FILTER:sendmailMTAClass,sendmailMTAClassURL:URL:sendmailMTAClass
NOTE: The macros shown above ${sendmailMTACluster} and $j are not actually
used when the binary expands the `@LDAP' token as class declarations are
not actually macro-expanded when read from the sendmail.cf file.
This can be used with class related commands such as RELAY_DOMAIN_FILE(),
MASQUERADE_DOMAIN_FILE(), etc:
Command sendmailMTAClassName
------- --------------------
CANONIFY_DOMAIN_FILE() Canonify
EXPOSED_USER_FILE() E
GENERICS_DOMAIN_FILE() G
LDAPROUTE_DOMAIN_FILE() LDAPRoute
LDAPROUTE_EQUIVALENT_FILE() LDAPRouteEquiv
LOCAL_USER_FILE() L
MASQUERADE_DOMAIN_FILE() M
MASQUERADE_EXCEPTION_FILE() N
RELAY_DOMAIN_FILE() R
VIRTUSER_DOMAIN_FILE() VirtHost
You can also add your own as any 'F'ile class of the form:
F{ClassName}@LDAP
^^^^^^^^^
will use "ClassName" for the sendmailMTAClassName.
An example LDAP LDIF entry would look like:
dn: sendmailMTAClassName=R, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAClass
sendmailMTACluster: Servers
sendmailMTAClassName: R
sendmailMTAClassValue: sendmail.org
sendmailMTAClassValue: example.com
sendmailMTAClassValue: 10.56.23
CAUTION: If your LDAP database contains the record above and *ALSO* a host
specific record such as:
dn: sendmailMTAClassName=R@etrn.sendmail.org, dc=sendmail, dc=org
objectClass: sendmailMTA
objectClass: sendmailMTAClass
sendmailMTAHost: etrn.sendmail.org
sendmailMTAClassName: R
sendmailMTAClassValue: example.com
the result will be similar to the aliases caution above. When the lookup
is done on etrn.sendmail.org, $={R} would contain all of the entries (from
both the cluster match and the host match). In other words, the effective
is additive.
If you prefer not to use the default LDAP schema for your classes, you can
specify the map parameters when using the class command. For example:
VIRTUSER_DOMAIN_FILE(`@ldap:-k (&(objectClass=virtHosts)(host=*)) -v host')
Remember, macros can not be used in a class declaration as the binary does
not expand them.
+--------------+
| LDAP ROUTING |
+--------------+
FEATURE(`ldap_routing') can be used to implement the IETF Internet Draft
LDAP Schema for Intranet Mail Routing
(draft-lachman-laser-ldap-mail-routing-01). This feature enables
LDAP-based rerouting of a particular address to either a different host
or a different address. The LDAP lookup is first attempted on the full
address (e.g., user@example.com) and then on the domain portion
(e.g., @example.com). Be sure to setup your domain for LDAP routing using
LDAPROUTE_DOMAIN(), e.g.:
LDAPROUTE_DOMAIN(`example.com')
Additionally, you can specify equivalent domains for LDAP routing using
LDAPROUTE_EQUIVALENT() and LDAPROUTE_EQUIVALENT_FILE(). 'Equivalent'
hostnames are mapped to $M (the masqueraded hostname for the server) before
the LDAP query. For example, if the mail is addressed to
user@host1.example.com, normally the LDAP lookup would only be done for
'user@host1.example.com' and '@host1.example.com'. However, if
LDAPROUTE_EQUIVALENT(`host1.example.com') is used, the lookups would also be
done on 'user@example.com' and '@example.com' after attempting the
host1.example.com lookups.
By default, the feature will use the schemas as specified in the draft
and will not reject addresses not found by the LDAP lookup. However,
this behavior can be changed by giving additional arguments to the FEATURE()
command:
FEATURE(`ldap_routing', <mailHost>, <mailRoutingAddress>, <bounce>,
<detail>, <nodomain>, <tempfail>)
where <mailHost> is a map definition describing how to look up an alternative
mail host for a particular address; <mailRoutingAddress> is a map definition
describing how to look up an alternative address for a particular address;
the <bounce> argument, if present and not the word "passthru", dictates
that mail should be bounced if neither a mailHost nor mailRoutingAddress
is found, if set to "sendertoo", the sender will be rejected if not
found in LDAP; and <detail> indicates what actions to take if the address
contains +detail information -- `strip' tries the lookup with the +detail
and if no matches are found, strips the +detail and tries the lookup again;
`preserve', does the same as `strip' but if a mailRoutingAddress match is
found, the +detail information is copied to the new address; the <nodomain>
argument, if present, will prevent the @domain lookup if the full
address is not found in LDAP; the <tempfail> argument, if set to
"tempfail", instructs the rules to give an SMTP 4XX temporary
error if the LDAP server gives the MTA a temporary failure, or if set to
"queue" (the default), the MTA will locally queue the mail.
The default <mailHost> map definition is:
ldap -1 -T<TMPF> -v mailHost -k (&(objectClass=inetLocalMailRecipient)
(mailLocalAddress=%0))
The default <mailRoutingAddress> map definition is:
ldap -1 -T<TMPF> -v mailRoutingAddress
-k (&(objectClass=inetLocalMailRecipient)
(mailLocalAddress=%0))
Note that neither includes the LDAP server hostname (-h server) or base DN
(-b o=org,c=COUNTRY), both necessary for LDAP queries. It is presumed that
your .mc file contains a setting for the confLDAP_DEFAULT_SPEC option with
these settings. If this is not the case, the map definitions should be
changed as described above. The "-T<TMPF>" is required in any user
specified map definition to catch temporary errors.
The following possibilities exist as a result of an LDAP lookup on an
address:
mailHost is mailRoutingAddress is Results in
----------- --------------------- ----------
set to a set mail delivered to
"local" host mailRoutingAddress
set to a not set delivered to
"local" host original address
set to a set mailRoutingAddress
remote host relayed to mailHost
set to a not set original address
remote host relayed to mailHost
not set set mail delivered to
mailRoutingAddress
not set not set delivered to
original address *OR*
bounced as unknown user
The term "local" host above means the host specified is in class {w}. If
the result would mean sending the mail to a different host, that host is
looked up in the mailertable before delivery.
Note that the last case depends on whether the third argument is given
to the FEATURE() command. The default is to deliver the message to the
original address.
The LDAP entries should be set up with an objectClass of
inetLocalMailRecipient and the address be listed in a mailLocalAddress
attribute. If present, there must be only one mailHost attribute and it
must contain a fully qualified host name as its value. Similarly, if
present, there must be only one mailRoutingAddress attribute and it must
contain an RFC 822 compliant address. Some example LDAP records (in LDIF
format):
dn: uid=tom, o=example.com, c=US
objectClass: inetLocalMailRecipient
mailLocalAddress: tom@example.com
mailRoutingAddress: thomas@mailhost.example.com
This would deliver mail for tom@example.com to thomas@mailhost.example.com.
dn: uid=dick, o=example.com, c=US
objectClass: inetLocalMailRecipient
mailLocalAddress: dick@example.com
mailHost: eng.example.com
This would relay mail for dick@example.com to the same address but redirect
the mail to MX records listed for the host eng.example.com (unless the
mailertable overrides).
dn: uid=harry, o=example.com, c=US
objectClass: inetLocalMailRecipient
mailLocalAddress: harry@example.com
mailHost: mktmail.example.com
mailRoutingAddress: harry@mkt.example.com
This would relay mail for harry@example.com to the MX records listed for
the host mktmail.example.com using the new address harry@mkt.example.com
when talking to that host.
dn: uid=virtual.example.com, o=example.com, c=US
objectClass: inetLocalMailRecipient
mailLocalAddress: @virtual.example.com
mailHost: server.example.com
mailRoutingAddress: virtual@example.com
This would send all mail destined for any username @virtual.example.com to
the machine server.example.com's MX servers and deliver to the address
virtual@example.com on that relay machine.
+---------------------------------+
| ANTI-SPAM CONFIGURATION CONTROL |
+---------------------------------+
The primary anti-spam features available in sendmail are:
* Relaying is denied by default.
* Better checking on sender information.
* Access database.
* Header checks.
Relaying (transmission of messages from a site outside your host (class
{w}) to another site except yours) is denied by default. Note that this
changed in sendmail 8.9; previous versions allowed relaying by default.
If you really want to revert to the old behaviour, you will need to use
FEATURE(`promiscuous_relay'). You can allow certain domains to relay
through your server by adding their domain name or IP address to class
{R} using RELAY_DOMAIN() and RELAY_DOMAIN_FILE() or via the access database
(described below). Note that IPv6 addresses must be prefaced with "IPv6:".
The file consists (like any other file based class) of entries listed on
separate lines, e.g.,
sendmail.org
128.32
IPv6:2002:c0a8:02c7
IPv6:2002:c0a8:51d2::23f4
host.mydomain.com
[UNIX:localhost]
Notice: the last entry allows relaying for connections via a UNIX
socket to the MTA/MSP. This might be necessary if your configuration
doesn't allow relaying by other means in that case, e.g., by having
localhost.$m in class {R} (make sure $m is not just a top level
domain).
If you use
FEATURE(`relay_entire_domain')
then any host in any of your local domains (that is, class {m})
will be relayed (that is, you will accept mail either to or from any
host in your domain).
You can also allow relaying based on the MX records of the host
portion of an incoming recipient address by using
FEATURE(`relay_based_on_MX')
For example, if your server receives a recipient of user@domain.com
and domain.com lists your server in its MX records, the mail will be
accepted for relay to domain.com. This feature may cause problems
if MX lookups for the recipient domain are slow or time out. In that
case, mail will be temporarily rejected. It is usually better to
maintain a list of hosts/domains for which the server acts as relay.
Note also that this feature will stop spammers from using your host
to relay spam but it will not stop outsiders from using your server
as a relay for their site (that is, they set up an MX record pointing
to your mail server, and you will relay mail addressed to them
without any prior arrangement). Along the same lines,
FEATURE(`relay_local_from')
will allow relaying if the sender specifies a return path (i.e.
MAIL FROM:<user@domain>) domain which is a local domain. This is a
dangerous feature as it will allow spammers to spam using your mail
server by simply specifying a return address of user@your.domain.com.
It should not be used unless absolutely necessary.
A slightly better solution is
FEATURE(`relay_mail_from')
which allows relaying if the mail sender is listed as RELAY in the
access map. If an optional argument `domain' (this is the literal
word `domain', not a placeholder) is given, the domain portion of
the mail sender is also checked to allowing relaying. This option
only works together with the tag From: for the LHS of the access
map entries. This feature allows spammers to abuse your mail server
by specifying a return address that you enabled in your access file.
This may be harder to figure out for spammers, but it should not
be used unless necessary. Instead use SMTP AUTH or STARTTLS to
allow relaying for roaming users.
If source routing is used in the recipient address (e.g.,
RCPT TO:<user%site.com@othersite.com>), sendmail will check
user@site.com for relaying if othersite.com is an allowed relay host
in either class {R}, class {m} if FEATURE(`relay_entire_domain') is used,
or the access database if FEATURE(`access_db') is used. To prevent
the address from being stripped down, use:
FEATURE(`loose_relay_check')
If you think you need to use this feature, you probably do not. This
should only be used for sites which have no control over the addresses
that they provide a gateway for. Use this FEATURE with caution as it
can allow spammers to relay through your server if not setup properly.
NOTICE: It is possible to relay mail through a system which the
anti-relay rules do not prevent: the case of a system that does use
FEATURE(`nouucp', `nospecial') / FEATURE(`nopercenthack', `nospecial')
(system A) and relays local messages to a mail hub (e.g., via
LOCAL_RELAY or LUSER_RELAY) (system B). If system B doesn't use the
same feature (nouucp / nopercenthack) at all, addresses of the form
<example.net!user@local.host> / <user%example.net@local.host>
would be relayed to <user@example.net>.
System A doesn't recognize `!' / `%' as an address separator and
therefore forwards it to the mail hub which in turns relays it
because it came from a trusted local host. So if a mailserver
allows UUCP (bang-format) / %-hack addresses, all systems from which
it allows relaying should do the same or reject those addresses.
As of 8.9, sendmail will refuse mail if the MAIL FROM: parameter has
an unresolvable domain (i.e., one that DNS, your local name service,
or special case rules in ruleset 3 cannot locate). This also applies
to addresses that use domain literals, e.g., <user@[1.2.3.4]>, if the
IP address can't be mapped to a host name. If you want to continue
to accept such domains, e.g., because you are inside a firewall that
has only a limited view of the Internet host name space (note that you
will not be able to return mail to them unless you have some "smart
host" forwarder), use
FEATURE(`accept_unresolvable_domains')
Alternatively, you can allow specific addresses by adding them to
the access map, e.g.,
From:unresolvable.domain OK
From:[1.2.3.4] OK
From:[1.2.4] OK
Notice: domains which are temporarily unresolvable are (temporarily)
rejected with a 451 reply code. If those domains should be accepted
(which is discouraged) then you can use
LOCAL_CONFIG
C{ResOk}TEMP
sendmail will also refuse mail if the MAIL FROM: parameter is not
fully qualified (i.e., contains a domain as well as a user). If you
want to continue to accept such senders, use
FEATURE(`accept_unqualified_senders')
Setting the DaemonPortOptions modifier 'u' overrides the default behavior,
i.e., unqualified addresses are accepted even without this FEATURE. If
this FEATURE is not used, the DaemonPortOptions modifier 'f' can be used
to enforce fully qualified domain names.
An ``access'' database can be created to accept or reject mail from
selected domains. For example, you may choose to reject all mail
originating from known spammers. To enable such a database, use
FEATURE(`access_db')
Notice: the access database is applied to the envelope addresses
and the connection information, not to the header.
The FEATURE macro can accept as second parameter the key file
definition for the database; for example
FEATURE(`access_db', `hash -T<TMPF> /etc/mail/access_map')
Notice: If a second argument is specified it must contain the option
`-T<TMPF>' as shown above. The optional parameters may be
`skip' enables SKIP as value part (see below).
`lookupdotdomain' another way to enable the feature of the
same name (see above).
`relaytofulladdress' enable entries of the form
To:user@example.com RELAY
to allow relaying to just a specific
e-mail address instead of an entire domain.
Remember, since /etc/mail/access is a database, after creating the text
file as described below, you must use makemap to create the database
map. For example:
makemap hash /etc/mail/access < /etc/mail/access
The table itself uses e-mail addresses, domain names, and network
numbers as keys. Note that IPv6 addresses must be prefaced with "IPv6:".
For example,
From:spammer@aol.com REJECT
From:cyberspammer.com REJECT
Connect:cyberspammer.com REJECT
Connect:TLD REJECT
Connect:192.168.212 REJECT
Connect:IPv6:2002:c0a8:02c7 RELAY
Connect:IPv6:2002:c0a8:51d2::23f4 REJECT
would refuse mail from spammer@aol.com, any user from cyberspammer.com
(or any host within the cyberspammer.com domain), any host in the entire
top level domain TLD, 192.168.212.* network, and the IPv6 address
2002:c0a8:51d2::23f4. It would allow relay for the IPv6 network
2002:c0a8:02c7::/48.
Entries in the access map should be tagged according to their type.
-Three tags are available:
+These tags are applicable:
Connect: connection information (${client_addr}, ${client_name})
From: envelope sender
To: envelope recipient
Notice: untagged entries are deprecated.
If the required item is looked up in a map, it will be tried first
with the corresponding tag in front, then (as fallback to enable
backward compatibility) without any tag, unless the specific feature
requires a tag. For example,
From:spammer@some.dom REJECT
To:friend.domain RELAY
Connect:friend.domain OK
Connect:from.domain RELAY
From:good@another.dom OK
From:another.dom REJECT
This would deny mails from spammer@some.dom but you could still
send mail to that address even if FEATURE(`blocklist_recipients')
is enabled. Your system will allow relaying to friend.domain, but
not from it (unless enabled by other means). Connections from that
domain will be allowed even if it ends up in one of the DNS based
rejection lists. Relaying is enabled from from.domain but not to
it (since relaying is based on the connection information for
outgoing relaying, the tag Connect: must be used; for incoming
relaying, which is based on the recipient address, To: must be
used). The last two entries allow mails from good@another.dom but
reject mail from all other addresses with another.dom as domain
part.
The value part of the map can contain:
OK Accept mail even if other rules in the running
ruleset would reject it, for example, if the domain
name is unresolvable. "Accept" does not mean
"relay", but at most acceptance for local
recipients. That is, OK allows less than RELAY.
RELAY Accept mail addressed to the indicated domain
(or address if `relaytofulladdress' is set) or
received from the indicated domain for relaying
through your SMTP server. RELAY also serves as
an implicit OK for the other checks.
REJECT Reject the sender or recipient with a general
purpose message.
DISCARD Discard the message completely using the
$#discard mailer. If it is used in check_compat,
it affects only the designated recipient, not
the whole message as it does in all other cases.
This should only be used if really necessary.
SKIP This can only be used for host/domain names
and IP addresses/nets. It will abort the current
search for this entry without accepting or rejecting
it but causing the default action.
### any text where ### is an RFC 821 compliant error code and
"any text" is a message to return for the command.
The entire string should be quoted to avoid
surprises:
"### any text"
Otherwise sendmail formats the text as email
addresses, e.g., it may remove spaces.
This type is deprecated, use one of the two
ERROR: entries below instead.
ERROR:### any text
as above, but useful to mark error messages as such.
If quotes need to be used to avoid modifications
(see above), they should be placed like this:
ERROR:"### any text"
ERROR:D.S.N:### any text
where D.S.N is an RFC 1893 compliant error code
and the rest as above. If quotes need to be used
to avoid modifications, they should be placed
like this:
ERROR:D.S.N:"### any text"
QUARANTINE:any text
Quarantine the message using the given text as the
quarantining reason.
For example:
From:cyberspammer.com ERROR:"550 We don't accept mail from spammers"
From:okay.cyberspammer.com OK
Connect:sendmail.org RELAY
To:sendmail.org RELAY
Connect:128.32 RELAY
Connect:128.32.2 SKIP
Connect:IPv6:1:2:3:4:5:6:7 RELAY
Connect:suspicious.example.com QUARANTINE:Mail from suspicious host
Connect:[127.0.0.3] OK
Connect:[IPv6:1:2:3:4:5:6:7:8] OK
would accept mail from okay.cyberspammer.com, but would reject mail
from all other hosts at cyberspammer.com with the indicated message.
It would allow relaying mail from and to any hosts in the sendmail.org
domain, and allow relaying from the IPv6 1:2:3:4:5:6:7:* network
and from the 128.32.*.* network except for the 128.32.2.* network,
which shows how SKIP is useful to exempt subnets/subdomains. The
last two entries are for checks against ${client_name} if the IP
address doesn't resolve to a hostname (or is considered as "may be
forged"). That is, using square brackets means these are host
names, not network numbers.
Warning: if you change the RFC 821 compliant error code from the default
value of 550, then you should probably also change the RFC 1893 compliant
error code to match it. For example, if you use
To:user@example.com ERROR:450 mailbox full
the error returned would be "450 5.0.0 mailbox full" which is wrong.
Use "ERROR:4.2.2:450 mailbox full" instead.
Note, UUCP users may need to add hostname.UUCP to the access database
or class {R}.
If you also use:
FEATURE(`relay_hosts_only')
then the above example will allow relaying for sendmail.org, but not
hosts within the sendmail.org domain. Note that this will also require
hosts listed in class {R} to be fully qualified host names.
You can also use the access database to block sender addresses based on
the username portion of the address. For example:
From:FREE.STEALTH.MAILER@ ERROR:550 Spam not accepted
Note that you must include the @ after the username to signify that
this database entry is for checking only the username portion of the
sender address.
If you use:
FEATURE(`blocklist_recipients')
then you can add entries to the map for local users, hosts in your
domains, or addresses in your domain which should not receive mail:
To:badlocaluser@ ERROR:550 Mailbox disabled for badlocaluser
To:host.my.TLD ERROR:550 That host does not accept mail
To:user@other.my.TLD ERROR:550 Mailbox disabled for this recipient
This would prevent a recipient of badlocaluser in any of the local
domains (class {w}), any user at host.my.TLD, and the single address
user@other.my.TLD from receiving mail. Please note: a local username
must be now tagged with an @ (this is consistent with the check of
the sender address, and hence it is possible to distinguish between
hostnames and usernames). Enabling this feature will keep you from
sending mails to all addresses that have an error message or REJECT
as value part in the access map. Taking the example from above:
spammer@aol.com REJECT
cyberspammer.com REJECT
Mail can't be sent to spammer@aol.com or anyone at cyberspammer.com.
That's why tagged entries should be used.
There are several DNS based blocklists which can be found by
querying a search engine. These are databases of spammers
maintained in DNS. To use such a database, specify
FEATURE(`dnsbl', `dnsbl.example.com')
This will cause sendmail to reject mail from any site listed in the
DNS based blocklist. You must select a DNS based blocklist domain
to check by specifying an argument to the FEATURE. The default
error message is
Rejected: IP-ADDRESS listed at SERVER
where IP-ADDRESS and SERVER are replaced by the appropriate
information. A second argument can be used to specify a different
text or action. For example,
FEATURE(`dnsbl', `dnsbl.example.com', `quarantine')
would quarantine the message if the client IP address is listed
at `dnsbl.example.com'.
By default, temporary lookup failures are ignored
and hence cause the connection not to be rejected by the DNS based
rejection list. This behavior can be changed by specifying a third
argument, which must be either `t' or a full error message. For
example:
FEATURE(`dnsbl', `dnsbl.example.com', `',
`"451 Temporary lookup failure for " $&{client_addr} " in dnsbl.example.com"')
If `t' is used, the error message is:
451 Temporary lookup failure of IP-ADDRESS at SERVER
where IP-ADDRESS and SERVER are replaced by the appropriate
information.
This FEATURE can be included several times to query different
DNS based rejection lists.
Notice: to avoid checking your own local domains against those
blocklists, use the access_db feature and add:
Connect:10.1 OK
Connect:127.0.0.1 RELAY
to the access map, where 10.1 is your local network. You may
want to use "RELAY" instead of "OK" to allow also relaying
instead of just disabling the DNS lookups in the blocklists.
The features described above make use of the check_relay, check_mail,
and check_rcpt rulesets. Note that check_relay checks the SMTP
client hostname and IP address when the connection is made to your
server. It does not check if a mail message is being relayed to
another server. That check is done in check_rcpt. If you wish to
include your own checks, you can put your checks in the rulesets
Local_check_relay, Local_check_mail, and Local_check_rcpt. For
example if you wanted to block senders with all numeric usernames
(i.e. 2312343@bigisp.com), you would use Local_check_mail and the
regex map:
LOCAL_CONFIG
Kallnumbers regex -a@MATCH ^[0-9]+$
LOCAL_RULESETS
SLocal_check_mail
# check address against various regex checks
R$* $: $>Parse0 $>3 $1
R$+ < @ bigisp.com. > $* $: $(allnumbers $1 $)
- R@MATCH $#error $: 553 Header Error
+ R@MATCH $#error $: 553 Address Error
These rules are called with the original arguments of the corresponding
check_* ruleset. If the local ruleset returns $#OK, no further checking
is done by the features described above and the mail is accepted. If
the local ruleset resolves to a mailer (such as $#error or $#discard),
the appropriate action is taken. Other results starting with $# are
interpreted by sendmail and may lead to unspecified behavior. Note: do
NOT create a mailer with the name OK. Return values that do not start
with $# are ignored, i.e., normal processing continues.
Delay all checks
----------------
By using FEATURE(`delay_checks') the rulesets check_mail and check_relay
will not be called when a client connects or issues a MAIL command,
respectively. Instead, those rulesets will be called by the check_rcpt
ruleset; they will be skipped if a sender has been authenticated using
a "trusted" mechanism, i.e., one that is defined via TRUST_AUTH_MECH().
If check_mail returns an error then the RCPT TO command will be rejected
with that error. If it returns some other result starting with $# then
check_relay will be skipped. If the sender address (or a part of it) is
listed in the access map and it has a RHS of OK or RELAY, then check_relay
will be skipped. This has an interesting side effect: if your domain is
my.domain and you have
my.domain RELAY
in the access map, then any e-mail with a sender address of
<user@my.domain> will not be rejected by check_relay even though
it would match the hostname or IP address. This allows spammers
to get around DNS based blocklist by faking the sender address. To
avoid this problem you have to use tagged entries:
To:my.domain RELAY
Connect:my.domain RELAY
if you need those entries at all (class {R} may take care of them).
FEATURE(`delay_checks') can take an optional argument:
FEATURE(`delay_checks', `friend')
enables spamfriend test
FEATURE(`delay_checks', `hater')
enables spamhater test
If such an argument is given, the recipient will be looked up in the
access map (using the tag Spam:). If the argument is `friend', then
the default behavior is to apply the other rulesets and make a SPAM
friend the exception. The rulesets check_mail and check_relay will be
skipped only if the recipient address is found and has RHS FRIEND. If
the argument is `hater', then the default behavior is to skip the rulesets
check_mail and check_relay and make a SPAM hater the exception. The
other two rulesets will be applied only if the recipient address is
found and has RHS HATER.
This allows for simple exceptions from the tests, e.g., by activating
the friend option and having
Spam:abuse@ FRIEND
in the access map, mail to abuse@localdomain will get through (where
"localdomain" is any domain in class {w}). It is also possible to
specify a full address or an address with +detail:
Spam:abuse@my.domain FRIEND
Spam:me+abuse@ FRIEND
Spam:spam.domain FRIEND
Note: The required tag has been changed in 8.12 from To: to Spam:.
This change is incompatible to previous versions. However, you can
(for now) simply add the new entries to the access map, the old
ones will be ignored. As soon as you removed the old entries from
the access map, specify a third parameter (`n') to this feature and
the backward compatibility rules will not be in the generated .cf
file.
Header Checks
-------------
You can also reject mail on the basis of the contents of headers.
This is done by adding a ruleset call to the 'H' header definition command
in sendmail.cf. For example, this can be used to check the validity of
a Message-ID: header:
LOCAL_CONFIG
HMessage-Id: $>CheckMessageId
LOCAL_RULESETS
SCheckMessageId
R< $+ @ $+ > $@ OK
R$* $#error $: 553 Header Error
The alternative format:
HSubject: $>+CheckSubject
that is, $>+ instead of $>, gives the full Subject: header including
comments to the ruleset (comments in parentheses () are stripped
by default).
A default ruleset for headers which don't have a specific ruleset
defined for them can be given by:
H*: $>CheckHdr
Notice:
1. All rules act on tokens as explained in doc/op/op.{me,ps,txt}.
That may cause problems with simple header checks due to the
tokenization. It might be simpler to use a regex map and apply it
to $&{currHeader}.
2. There are no default rulesets coming with this distribution of
sendmail. You can write your own, can search the WWW for examples,
or take a look at cf/cf/knecht.mc.
3. When using a default ruleset for headers, the name of the header
currently being checked can be found in the $&{hdr_name} macro.
After all of the headers are read, the check_eoh ruleset will be called for
any final header-related checks. The ruleset is called with the number of
headers and the size of all of the headers in bytes separated by $|. One
example usage is to reject messages which do not have a Message-Id:
header. However, the Message-Id: header is *NOT* a required header and is
not a guaranteed spam indicator. This ruleset is an example and should
probably not be used in production.
LOCAL_CONFIG
Kstorage macro
HMessage-Id: $>CheckMessageId
LOCAL_RULESETS
SCheckMessageId
# Record the presence of the header
R$* $: $(storage {MessageIdCheck} $@ OK $) $1
R< $+ @ $+ > $@ OK
R$* $#error $: 553 Header Error
Scheck_eoh
# Check the macro
R$* $: < $&{MessageIdCheck} >
# Clear the macro for the next message
R$* $: $(storage {MessageIdCheck} $) $1
# Has a Message-Id: header
R< $+ > $@ OK
# Allow missing Message-Id: from local mail
R$* $: < $&{client_name} >
R< > $@ OK
R< $=w > $@ OK
# Otherwise, reject the mail
R$* $#error $: 553 Header Error
+--------------------+
| CONNECTION CONTROL |
+--------------------+
The features ratecontrol and conncontrol allow to establish connection
limits per client IP address or net. These features can limit the
rate of connections (connections per time unit) or the number of
incoming SMTP connections, respectively. If enabled, appropriate
rulesets are called at the end of check_relay, i.e., after DNS
blocklists and generic access_db operations. The features require
FEATURE(`access_db') to be listed earlier in the mc file.
Note: FEATURE(`delay_checks') delays those connection control checks
after a recipient address has been received, hence making these
connection control features less useful. To run the checks as early
as possible, specify the parameter `nodelay', e.g.,
FEATURE(`ratecontrol', `nodelay')
In that case, FEATURE(`delay_checks') has no effect on connection
control (and it must be specified earlier in the mc file).
An optional second argument `terminate' specifies whether the
rulesets should return the error code 421 which will cause
sendmail to terminate the session with that error if it is
returned from check_relay, i.e., not delayed as explained in
the previous paragraph. Example:
FEATURE(`ratecontrol', `nodelay', `terminate')
+----------+
| STARTTLS |
+----------+
In this text, cert will be used as an abbreviation for X.509 certificate,
DN (CN) is the distinguished (common) name of a cert, and CA is a
certification authority, which signs (issues) certs.
For STARTTLS to be offered by sendmail you need to set at least
these variables (the file names and paths are just examples):
define(`confCACERT_PATH', `/etc/mail/certs/')
define(`confCACERT', `/etc/mail/certs/CA.cert.pem')
define(`confSERVER_CERT', `/etc/mail/certs/my.cert.pem')
define(`confSERVER_KEY', `/etc/mail/certs/my.key.pem')
On systems which do not have the compile flag HASURANDOM set (see
sendmail/README) you also must set confRAND_FILE.
See doc/op/op.{me,ps,txt} for more information about these options,
especially the sections ``Certificates for STARTTLS'' and ``PRNG for
STARTTLS''.
Macros related to STARTTLS are:
${cert_issuer} holds the DN of the CA (the cert issuer).
${cert_subject} holds the DN of the cert (called the cert subject).
${cn_issuer} holds the CN of the CA (the cert issuer).
${cn_subject} holds the CN of the cert (called the cert subject).
${tls_version} the TLS/SSL version used for the connection, e.g., TLSv1,
TLSv1/SSLv3, SSLv3, SSLv2.
${cipher} the cipher used for the connection, e.g., EDH-DSS-DES-CBC3-SHA,
EDH-RSA-DES-CBC-SHA, DES-CBC-MD5, DES-CBC3-SHA.
${cipher_bits} the keylength (in bits) of the symmetric encryption algorithm
used for the connection.
${verify} holds the result of the verification of the presented cert.
Possible values are:
OK verification succeeded.
NO no cert presented.
NOT no cert requested.
FAIL cert presented but could not be verified,
e.g., the cert of the signing CA is missing.
NONE STARTTLS has not been performed.
TEMP temporary error occurred.
PROTOCOL protocol error occurred (SMTP level).
SOFTWARE STARTTLS handshake failed.
${server_name} the name of the server of the current outgoing SMTP
connection.
${server_addr} the address of the server of the current outgoing SMTP
connection.
Relaying
--------
SMTP STARTTLS can allow relaying for remote SMTP clients which have
successfully authenticated themselves. If the verification of the cert
failed (${verify} != OK), relaying is subject to the usual rules.
Otherwise the DN of the issuer is looked up in the access map using the
tag CERTISSUER. If the resulting value is RELAY, relaying is allowed.
If it is SUBJECT, the DN of the cert subject is looked up next in the
access map using the tag CERTSUBJECT. If the value is RELAY, relaying
is allowed.
To make things a bit more flexible (or complicated), the values for
${cert_issuer} and ${cert_subject} can be optionally modified by regular
expressions defined in the m4 variables _CERT_REGEX_ISSUER_ and
_CERT_REGEX_SUBJECT_, respectively. To avoid problems with those macros in
rulesets and map lookups, they are modified as follows: each non-printable
character and the characters '<', '>', '(', ')', '"', '+', ' ' are replaced
by their HEX value with a leading '+'. For example:
/C=US/ST=California/O=endmail.org/OU=private/CN=Darth Mail (Cert)/emailAddress=
darth+cert@endmail.org
is encoded as:
/C=US/ST=California/O=endmail.org/OU=private/CN=
Darth+20Mail+20+28Cert+29/emailAddress=darth+2Bcert@endmail.org
(line breaks have been inserted for readability).
-The macros which are subject to this encoding are ${cert_subject},
-${cert_issuer}, ${cn_subject}, and ${cn_issuer}.
+The macros which are subject to this encoding are ${cert_subject},
+${cert_issuer}, ${cn_subject}, and ${cn_issuer}.
Examples:
To allow relaying for everyone who can present a cert signed by
/C=US/ST=California/O=endmail.org/OU=private/CN=
Darth+20Mail+20+28Cert+29/emailAddress=darth+2Bcert@endmail.org
simply use:
CertIssuer:/C=US/ST=California/O=endmail.org/OU=private/CN=
Darth+20Mail+20+28Cert+29/emailAddress=darth+2Bcert@endmail.org RELAY
To allow relaying only for a subset of machines that have a cert signed by
/C=US/ST=California/O=endmail.org/OU=private/CN=
Darth+20Mail+20+28Cert+29/emailAddress=darth+2Bcert@endmail.org
use:
CertIssuer:/C=US/ST=California/O=endmail.org/OU=private/CN=
Darth+20Mail+20+28Cert+29/emailAddress=darth+2Bcert@endmail.org SUBJECT
CertSubject:/C=US/ST=California/O=endmail.org/OU=private/CN=
DeathStar/emailAddress=deathstar@endmail.org RELAY
Note: line breaks have been inserted after "CN=" for readability,
each tagged entry must be one (long) line in the access map.
Of course it is also possible to write a simple ruleset that allows
relaying for everyone who can present a cert that can be verified, e.g.,
LOCAL_RULESETS
SLocal_check_rcpt
R$* $: $&{verify}
ROK $# OK
Allowing Connections
--------------------
The rulesets tls_server, tls_client, and tls_rcpt are used to decide whether
an SMTP connection is accepted (or should continue).
tls_server is called when sendmail acts as client after a STARTTLS command
(should) have been issued. The parameter is the value of ${verify}.
tls_client is called when sendmail acts as server, after a STARTTLS command
has been issued, and from check_mail. The parameter is the value of
${verify} and STARTTLS or MAIL, respectively.
Both rulesets behave the same. If no access map is in use, the connection
will be accepted unless ${verify} is SOFTWARE, in which case the connection
is always aborted. For tls_server/tls_client, ${client_name}/${server_name}
is looked up in the access map using the tag TLS_Srv/TLS_Clt, which is done
with the ruleset LookUpDomain. If no entry is found, ${client_addr}
(${server_addr}) is looked up in the access map (same tag, ruleset
LookUpAddr). If this doesn't result in an entry either, just the tag is
looked up in the access map (included the trailing colon). Notice:
requiring that e-mail is sent to a server only encrypted, e.g., via
TLS_Srv:secure.domain ENCR:112
doesn't necessarily mean that e-mail sent to that domain is encrypted.
If the domain has multiple MX servers, e.g.,
secure.domain. IN MX 10 mail.secure.domain.
secure.domain. IN MX 50 mail.other.domain.
then mail to user@secure.domain may go unencrypted to mail.other.domain.
tls_rcpt can be used to address this problem.
tls_rcpt is called before a RCPT TO: command is sent. The parameter is the
current recipient. This ruleset is only defined if FEATURE(`access_db')
is selected. A recipient address user@domain is looked up in the access
map in four formats: TLS_Rcpt:user@domain, TLS_Rcpt:user@, TLS_Rcpt:domain,
and TLS_Rcpt:; the first match is taken.
The result of the lookups is then used to call the ruleset TLS_connection,
which checks the requirement specified by the RHS in the access map against
the actual parameters of the current TLS connection, esp. ${verify} and
${cipher_bits}. Legal RHSs in the access map are:
VERIFY verification must have succeeded
VERIFY:bits verification must have succeeded and ${cipher_bits} must
be greater than or equal bits.
ENCR:bits ${cipher_bits} must be greater than or equal bits.
The RHS can optionally be prefixed by TEMP+ or PERM+ to select a temporary
or permanent error. The default is a temporary error code (403 4.7.0)
unless the macro TLS_PERM_ERR is set during generation of the .cf file.
If a certain level of encryption is required, then it might also be
possible that this level is provided by the security layer from a SASL
algorithm, e.g., DIGEST-MD5.
Furthermore, there can be a list of extensions added. Such a list
starts with '+' and the items are separated by '++'. Allowed
extensions are:
CN:name name must match ${cn_subject}
CN ${client_name}/${server_name} must match ${cn_subject}
CS:name name must match ${cert_subject}
CI:name name must match ${cert_issuer}
CITag:MYTag look up MYTag:${cert_issuer} in access map; the check
only succeeds if it is found with a RHS of OK.
Example: e-mail sent to secure.example.com should only use an encrypted
connection. E-mail received from hosts within the laptop.example.com domain
should only be accepted if they have been authenticated. The host which
receives e-mail for darth@endmail.org must present a cert that uses the
CN smtp.endmail.org. E-mail sent to safe.example.com must be verified,
have a matching CN, and must present a cert signed by a CA with one of
the listed DNs.
TLS_Srv:secure.example.com ENCR:112
TLS_Clt:laptop.example.com PERM+VERIFY:112
TLS_Rcpt:darth@endmail.org ENCR:112+CN:smtp.endmail.org
TLS_Srv:safe.example.net VERIFY+CN++CITag:MyCA
MyCA:/C=US/ST=CA/O=safe/CN=example.net/ OK
MyCA:/C=US/ST=CA/O=secure/CN=example.net/ OK
TLS Options per Session
-----------------------
By default STARTTLS is used whenever possible. However, there are
MTAs with STARTTLS interoperability issues. To be able to send to
(or receive from) those MTAs several features are available:
1) Various TLS options be be set per IP/domain.
2) STARTTLS can be turned off for specific IP addresses/domains.
About 1): the rulesets tls_srv_features and tls_clt_features can
be used to return a (semicolon separated) list of TLS related
options:
- Options: compare {Server,Client}SSLOptions.
- CipherList: same as the global option.

Received: Header
----------------
The Received: header reveals whether STARTTLS has been used. It contains an
extra line:
(version=${tls_version} cipher=${cipher} bits=${cipher_bits} verify=${verify})
+---------------------+
| SMTP AUTHENTICATION |
+---------------------+
The macros ${auth_authen}, ${auth_author}, and ${auth_type} can be
used in anti-relay rulesets to allow relaying for those users that
authenticated themselves. A very simple example is:
SLocal_check_rcpt
R$* $: $&{auth_type}
R$+ $# OK
which checks whether a user has successfully authenticated using
any available mechanism. Depending on the setup of the Cyrus SASL
library, more sophisticated rulesets might be required, e.g.,
SLocal_check_rcpt
R$* $: $&{auth_type} $| $&{auth_authen}
RDIGEST-MD5 $| $+@$=w $# OK
to allow relaying for users that authenticated using DIGEST-MD5
and have an identity in the local domains.
The ruleset trust_auth is used to determine whether a given AUTH=
parameter (that is passed to this ruleset) should be trusted. This
ruleset may make use of the other ${auth_*} macros. Only if the
ruleset resolves to the error mailer, the AUTH= parameter is not
trusted. A user supplied ruleset Local_trust_auth can be written
to modify the default behavior, which only trust the AUTH=
parameter if it is identical to the authenticated user.
Per default, relaying is allowed for any user who authenticated
via a "trusted" mechanism, i.e., one that is defined via
TRUST_AUTH_MECH(`list of mechanisms')
For example:
TRUST_AUTH_MECH(`KERBEROS_V4 DIGEST-MD5')
If the selected mechanism provides a security layer the number of
bits used for the key of the symmetric cipher is stored in the
macro ${auth_ssf}.
Providing SMTP AUTH Data when sendmail acts as Client
-----------------------------------------------------
If sendmail acts as client, it needs some information how to
authenticate against another MTA. This information can be provided
by the ruleset authinfo or by the option DefaultAuthInfo. The
authinfo ruleset looks up {server_name} using the tag AuthInfo: in
the access map. If no entry is found, {server_addr} is looked up
in the same way and finally just the tag AuthInfo: to provide
default values. Note: searches for domain parts or IP nets are
only performed if the access map is used; if the authinfo feature
is used then only up to three lookups are performed (two exact
matches, one default).
Note: If your daemon does client authentication when sending, and
if it uses either PLAIN or LOGIN authentication, then you *must*
prevent ordinary users from seeing verbose output. Do NOT install
sendmail set-user-ID. Use PrivacyOptions to turn off verbose output
("goaway" works for this).
Notice: the default configuration file causes the option DefaultAuthInfo
to fail since the ruleset authinfo is in the .cf file. If you really
want to use DefaultAuthInfo (it is deprecated) then you have to
remove the ruleset.
The RHS for an AuthInfo: entry in the access map should consists of a
list of tokens, each of which has the form: "TDstring" (including
the quotes). T is a tag which describes the item, D is a delimiter,
either ':' for simple text or '=' for a base64 encoded string.
Valid values for the tag are:
U user (authorization) id
I authentication id
P password
R realm
M list of mechanisms delimited by spaces
Example entries are:
AuthInfo:other.dom "U:user" "I:user" "P:secret" "R:other.dom" "M:DIGEST-MD5"
AuthInfo:host.more.dom "U:user" "P=c2VjcmV0"
User id or authentication id must exist as well as the password. All
other entries have default values. If one of user or authentication
id is missing, the existing value is used for the missing item.
If "R:" is not specified, realm defaults to $j. The list of mechanisms
defaults to those specified by AuthMechanisms.
Since this map contains sensitive information, either the access
map must be unreadable by everyone but root (or the trusted user)
or FEATURE(`authinfo') must be used which provides a separate map.
Notice: It is not checked whether the map is actually
group/world-unreadable, this is left to the user.
+--------------------------------+
| ADDING NEW MAILERS OR RULESETS |
+--------------------------------+
Sometimes you may need to add entirely new mailers or rulesets. They
should be introduced with the constructs MAILER_DEFINITIONS and
LOCAL_RULESETS respectively. For example:
MAILER_DEFINITIONS
Mmymailer, ...
...
LOCAL_RULESETS
Smyruleset
...
-Local additions for the rulesets srv_features, try_tls, tls_rcpt,
-tls_client, and tls_server can be made using LOCAL_SRV_FEATURES,
-LOCAL_TRY_TLS, LOCAL_TLS_RCPT, LOCAL_TLS_CLIENT, and LOCAL_TLS_SERVER,
-respectively. For example, to add a local ruleset that decides
-whether to try STARTTLS in a sendmail client, use:
+Local additions for the rulesets srv_features, clt_features, try_tls,
+tls_rcpt, tls_client, and tls_server can be made using LOCAL_SRV_FEATURES,
+LOCAL_CLT_FEATURES, LOCAL_TRY_TLS, LOCAL_TLS_RCPT, LOCAL_TLS_CLIENT,
+and LOCAL_TLS_SERVER, respectively. For example, to add a local
+ruleset that decides whether to try STARTTLS in a sendmail client, use:
LOCAL_TRY_TLS
R...
Note: you don't need to add a name for the ruleset, it is implicitly
defined by using the appropriate macro.
+-------------------------+
| ADDING NEW MAIL FILTERS |
+-------------------------+
Sendmail supports mail filters to filter incoming SMTP messages according
to the "Sendmail Mail Filter API" documentation. These filters can be
configured in your mc file using the two commands:
MAIL_FILTER(`name', `equates')
INPUT_MAIL_FILTER(`name', `equates')
The first command, MAIL_FILTER(), simply defines a filter with the given
name and equates. For example:
MAIL_FILTER(`archive', `S=local:/var/run/archivesock, F=R')
This creates the equivalent sendmail.cf entry:
Xarchive, S=local:/var/run/archivesock, F=R
The INPUT_MAIL_FILTER() command performs the same actions as MAIL_FILTER
but also populates the m4 variable `confINPUT_MAIL_FILTERS' with the name
of the filter such that the filter will actually be called by sendmail.
For example, the two commands:
INPUT_MAIL_FILTER(`archive', `S=local:/var/run/archivesock, F=R')
INPUT_MAIL_FILTER(`spamcheck', `S=inet:2525@localhost, F=T')
are equivalent to the three commands:
MAIL_FILTER(`archive', `S=local:/var/run/archivesock, F=R')
MAIL_FILTER(`spamcheck', `S=inet:2525@localhost, F=T')
define(`confINPUT_MAIL_FILTERS', `archive, spamcheck')
In general, INPUT_MAIL_FILTER() should be used unless you need to define
more filters than you want to use for `confINPUT_MAIL_FILTERS'.
Note that setting `confINPUT_MAIL_FILTERS' after any INPUT_MAIL_FILTER()
commands will clear the list created by the prior INPUT_MAIL_FILTER()
commands.
+-------------------------+
| QUEUE GROUP DEFINITIONS |
+-------------------------+
In addition to the queue directory (which is the default queue group
called "mqueue"), sendmail can deal with multiple queue groups, which
are collections of queue directories with the same behaviour. Queue
groups can be defined using the command:
QUEUE_GROUP(`name', `equates')
For details about queue groups, please see doc/op/op.{me,ps,txt}.
+-------------------------------+
| NON-SMTP BASED CONFIGURATIONS |
+-------------------------------+
These configuration files are designed primarily for use by
SMTP-based sites. They may not be well tuned for UUCP-only or
UUCP-primarily nodes (the latter is defined as a small local net
connected to the rest of the world via UUCP). However, there is
one hook to handle some special cases.
You can define a ``smart host'' that understands a richer address syntax
using:
define(`SMART_HOST', `mailer:hostname')
In this case, the ``mailer:'' defaults to "relay". Any messages that
can't be handled using the usual UUCP rules are passed to this host.
If you are on a local SMTP-based net that connects to the outside
world via UUCP, you can use LOCAL_NET_CONFIG to add appropriate rules.
For example:
define(`SMART_HOST', `uucp-new:uunet')
LOCAL_NET_CONFIG
R$* < @ $* .$m. > $* $#smtp $@ $2.$m. $: $1 < @ $2.$m. > $3
This will cause all names that end in your domain name ($m) to be sent
via SMTP; anything else will be sent via uucp-new (smart UUCP) to uunet.
If you have FEATURE(`nocanonify'), you may need to omit the dots after
the $m. If you are running a local DNS inside your domain which is
not otherwise connected to the outside world, you probably want to
use:
define(`SMART_HOST', `smtp:fire.wall.com')
LOCAL_NET_CONFIG
R$* < @ $* . > $* $#smtp $@ $2. $: $1 < @ $2. > $3
That is, send directly only to things you found in your DNS lookup;
anything else goes through SMART_HOST.
You may need to turn off the anti-spam rules in order to accept
UUCP mail with FEATURE(`promiscuous_relay') and
FEATURE(`accept_unresolvable_domains').
+-----------+
| WHO AM I? |
+-----------+
Normally, the $j macro is automatically defined to be your fully
qualified domain name (FQDN). Sendmail does this by getting your
host name using gethostname and then calling gethostbyname on the
result. For example, in some environments gethostname returns
only the root of the host name (such as "foo"); gethostbyname is
supposed to return the FQDN ("foo.bar.com"). In some (fairly rare)
cases, gethostbyname may fail to return the FQDN. In this case
you MUST define confDOMAIN_NAME to be your fully qualified domain
name. This is usually done using:
Dmbar.com
define(`confDOMAIN_NAME', `$w.$m')dnl
+-----------------------------------+
| ACCEPTING MAIL FOR MULTIPLE NAMES |
+-----------------------------------+
If your host is known by several different names, you need to augment
class {w}. This is a list of names by which your host is known, and
anything sent to an address using a host name in this list will be
treated as local mail. You can do this in two ways: either create the
file /etc/mail/local-host-names containing a list of your aliases (one per
line), and use ``FEATURE(`use_cw_file')'' in the .mc file, or add
``LOCAL_DOMAIN(`alias.host.name')''. Be sure you use the fully-qualified
name of the host, rather than a short name.
If you want to have different address in different domains, take
a look at the virtusertable feature, which is also explained at
http://www.sendmail.org/virtual-hosting.html
+--------------------+
| USING MAILERTABLES |
+--------------------+
To use FEATURE(`mailertable'), you will have to create an external
database containing the routing information for various domains.
For example, a mailertable file in text format might be:
.my.domain xnet:%1.my.domain
uuhost1.my.domain uucp-new:uuhost1
.bitnet smtp:relay.bit.net
This should normally be stored in /etc/mail/mailertable. The actual
database version of the mailertable is built using:
makemap hash /etc/mail/mailertable < /etc/mail/mailertable
The semantics are simple. Any LHS entry that does not begin with
a dot matches the full host name indicated. LHS entries beginning
with a dot match anything ending with that domain name (including
the leading dot) -- that is, they can be thought of as having a
leading ".+" regular expression pattern for a non-empty sequence of
characters. Matching is done in order of most-to-least qualified
-- for example, even though ".my.domain" is listed first in the
above example, an entry of "uuhost1.my.domain" will match the second
entry since it is more explicit. Note: e-mail to "user@my.domain"
does not match any entry in the above table. You need to have
something like:
my.domain esmtp:host.my.domain
The RHS should always be a "mailer:host" pair. The mailer is the
configuration name of a mailer (that is, an M line in the
sendmail.cf file). The "host" will be the hostname passed to
that mailer. In domain-based matches (that is, those with leading
dots) the "%1" may be used to interpolate the wildcarded part of
the host name. For example, the first line above sends everything
addressed to "anything.my.domain" to that same host name, but using
the (presumably experimental) xnet mailer.
In some cases you may want to temporarily turn off MX records,
particularly on gateways. For example, you may want to MX
everything in a domain to one machine that then forwards it
directly. To do this, you might use the DNS configuration:
*.domain. IN MX 0 relay.machine
and on relay.machine use the mailertable:
.domain smtp:[gateway.domain]
The [square brackets] turn off MX records for this host only.
If you didn't do this, the mailertable would use the MX record
again, which would give you an MX loop. Note that the use of
wildcard MX records is almost always a bad idea. Please avoid
using them if possible.
+--------------------------------+
| USING USERDB TO MAP FULL NAMES |
+--------------------------------+
The user database was not originally intended for mapping full names
to login names (e.g., Eric.Allman => eric), but some people are using
it that way. (it is recommended that you set up aliases for this
purpose instead -- since you can specify multiple alias files, this
is fairly easy.) The intent was to locate the default maildrop at
a site, but allow you to override this by sending to a specific host.
If you decide to set up the user database in this fashion, it is
imperative that you not use FEATURE(`stickyhost') -- otherwise,
e-mail sent to Full.Name@local.host.name will be rejected.
To build the internal form of the user database, use:
makemap btree /etc/mail/userdb < /etc/mail/userdb.txt
As a general rule, it is an extremely bad idea to using full names
as e-mail addresses, since they are not in any sense unique. For
example, the UNIX software-development community has at least two
well-known Peter Deutsches, and at one time Bell Labs had two
Stephen R. Bournes with offices along the same hallway. Which one
will be forced to suffer the indignity of being Stephen_R_Bourne_2?
The less famous of the two, or the one that was hired later?
Finger should handle full names (and be fuzzy). Mail should use
handles, and not be fuzzy.
+--------------------------------+
| MISCELLANEOUS SPECIAL FEATURES |
+--------------------------------+
Plussed users
Sometimes it is convenient to merge configuration on a
centralized mail machine, for example, to forward all
root mail to a mail server. In this case it might be
useful to be able to treat the root addresses as a class
of addresses with subtle differences. You can do this
using plussed users. For example, a client might include
the alias:
root: root+client1@server
On the server, this will match an alias for "root+client1".
If that is not found, the alias "root+*" will be tried,
then "root".
+----------------+
| SECURITY NOTES |
+----------------+
A lot of sendmail security comes down to you. Sendmail 8 is much
more careful about checking for security problems than previous
versions, but there are some things that you still need to watch
for. In particular:
* Make sure the aliases file is not writable except by trusted
system personnel. This includes both the text and database
version.
* Make sure that other files that sendmail reads, such as the
mailertable, are only writable by trusted system personnel.
* The queue directory should not be world writable PARTICULARLY
if your system allows "file giveaways" (that is, if a non-root
user can chown any file they own to any other user).
* If your system allows file giveaways, DO NOT create a publicly
writable directory for forward files. This will allow anyone
to steal anyone else's e-mail. Instead, create a script that
copies the .forward file from users' home directories once a
night (if you want the non-NFS-mounted forward directory).
* If your system allows file giveaways, you'll find that
sendmail is much less trusting of :include: files -- in
particular, you'll have to have /SENDMAIL/ANY/SHELL/ in
/etc/shells before they will be trusted (that is, before
files and programs listed in them will be honored).
In general, file giveaways are a mistake -- if you can turn them
off, do so.
+--------------------------------+
| TWEAKING CONFIGURATION OPTIONS |
+--------------------------------+
There are a large number of configuration options that don't normally
need to be changed. However, if you feel you need to tweak them,
you can define the following M4 variables. Note that some of these
variables require formats that are defined in RFC 2821 or RFC 2822.
Before changing them you need to make sure you do not violate those
(and other relevant) RFCs.
This list is shown in four columns: the name you define, the default
value for that definition, the option or macro that is affected
(either Ox for an option or Dx for a macro), and a brief description.
Greater detail of the semantics can be found in the Installation
and Operations Guide.
Some options are likely to be deprecated in future versions -- that is,
the option is only included to provide back-compatibility. These are
marked with "*".
Remember that these options are M4 variables, and hence may need to
be quoted. In particular, arguments with commas will usually have to
be ``double quoted, like this phrase'' to avoid having the comma
confuse things. This is common for alias file definitions and for
the read timeout.
M4 Variable Name Configuration [Default] & Description
================ ============= =======================
confMAILER_NAME $n macro [MAILER-DAEMON] The sender name used
for internally generated outgoing
messages.
confDOMAIN_NAME $j macro If defined, sets $j. This should
only be done if your system cannot
determine your local domain name,
and then it should be set to
$w.Foo.COM, where Foo.COM is your
domain name.
confCF_VERSION $Z macro If defined, this is appended to the
configuration version name.
confLDAP_CLUSTER ${sendmailMTACluster} macro
If defined, this is the LDAP
cluster to use for LDAP searches
as described above in ``USING LDAP
FOR ALIASES, MAPS, AND CLASSES''.
confFROM_HEADER From: [$?x$x <$g>$|$g$.] The format of an
internally generated From: address.
confRECEIVED_HEADER Received:

$.$?{auth_type}(authenticated)
$.by $j ($v/$Z)$?r with $r$. id $i$?u
for $u; $|;
$.$b]
The format of the Received: header
in messages passed through this host.
It is unwise to try to change this.
confMESSAGEID_HEADER Message-Id: [<$t.$i@$j>] The format of an
internally generated Message-Id:
header.
confCW_FILE Fw class [/etc/mail/local-host-names] Name
of file used to get the local
additions to class {w} (local host
names).
confCT_FILE Ft class [/etc/mail/trusted-users] Name of
file used to get the local additions
to class {t} (trusted users).
confCR_FILE FR class [/etc/mail/relay-domains] Name of
file used to get the local additions
to class {R} (hosts allowed to relay).
confTRUSTED_USERS Ct class [no default] Names of users to add to
the list of trusted users. This list
always includes root, uucp, and daemon.
See also FEATURE(`use_ct_file').
confTRUSTED_USER TrustedUser [no default] Trusted user for file
ownership and starting the daemon.
Not to be confused with
confTRUSTED_USERS (see above).
confSMTP_MAILER - [esmtp] The mailer name used when
SMTP connectivity is required.
One of "smtp", "smtp8",
"esmtp", or "dsmtp".
confUUCP_MAILER - [uucp-old] The mailer to be used by
default for bang-format recipient
addresses. See also discussion of
class {U}, class {Y}, and class {Z}
in the MAILER(`uucp') section.
confLOCAL_MAILER - [local] The mailer name used when
local connectivity is required.
Almost always "local".
confRELAY_MAILER - [relay] The default mailer name used
for relaying any mail (e.g., to a
BITNET_RELAY, a SMART_HOST, or
whatever). This can reasonably be
"uucp-new" if you are on a
UUCP-connected site.
confSEVEN_BIT_INPUT SevenBitInput [False] Force input to seven bits?
confEIGHT_BIT_HANDLING EightBitMode [pass8] 8-bit data handling
confALIAS_WAIT AliasWait [10m] Time to wait for alias file
rebuild until you get bored and
decide that the apparently pending
rebuild failed.
confMIN_FREE_BLOCKS MinFreeBlocks [100] Minimum number of free blocks on
queue filesystem to accept SMTP mail.
(Prior to 8.7 this was minfree/maxsize,
where minfree was the number of free
blocks and maxsize was the maximum
message size. Use confMAX_MESSAGE_SIZE
for the second value now.)
confMAX_MESSAGE_SIZE MaxMessageSize [infinite] The maximum size of messages
that will be accepted (in bytes).
confBLANK_SUB BlankSub [.] Blank (space) substitution
character.
confCON_EXPENSIVE HoldExpensive [False] Avoid connecting immediately
to mailers marked expensive.
confCHECKPOINT_INTERVAL CheckpointInterval
[10] Checkpoint queue files every N
recipients.
confDELIVERY_MODE DeliveryMode [background] Default delivery mode.
confERROR_MODE ErrorMode [print] Error message mode.
confERROR_MESSAGE ErrorHeader [undefined] Error message header/file.
confSAVE_FROM_LINES SaveFromLine Save extra leading From_ lines.
confTEMP_FILE_MODE TempFileMode [0600] Temporary file mode.
confMATCH_GECOS MatchGECOS [False] Match GECOS field.

mode] Ignore dot as terminator for
incoming messages?
confBIND_OPTS ResolverOptions [undefined] Default options for DNS
resolver.
confMIME_FORMAT_ERRORS* SendMimeErrors [True] Send error messages as MIME-
encapsulated messages per RFC 1344.
confFORWARD_PATH ForwardPath [$z/.forward.$w:$z/.forward]
The colon-separated list of places to
search for .forward files. N.B.: see
the Security Notes section.
confMCI_CACHE_SIZE ConnectionCacheSize
[2] Size of open connection cache.
confMCI_CACHE_TIMEOUT ConnectionCacheTimeout
[5m] Open connection cache timeout.
confHOST_STATUS_DIRECTORY HostStatusDirectory
[undefined] If set, host status is kept
on disk between sendmail runs in the
named directory tree. This need not be
a full pathname, in which case it is
interpreted relative to the queue
directory.
confSINGLE_THREAD_DELIVERY SingleThreadDelivery
[False] If this option and the
HostStatusDirectory option are both
set, single thread deliveries to other
hosts. That is, don't allow any two
sendmails on this host to connect
simultaneously to any other single
host. This can slow down delivery in
some cases, in particular since a
cached but otherwise idle connection
to a host will prevent other sendmails
from connecting to the other host.
confUSE_COMPRESSED_IPV6_ADDRESSES
UseCompressedIPv6Addresses
[undefined] If set, use the compressed
form of IPv6 addresses, such as
IPV6:::1, instead of the uncompressed
form, such as IPv6:0:0:0:0:0:0:0:1.
confUSE_ERRORS_TO* UseErrorsTo [False] Use the Errors-To: header to
deliver error messages. This should
not be necessary because of general
acceptance of the envelope/header
distinction.
confLOG_LEVEL LogLevel [9] Log level.
confME_TOO MeToo [True] Include sender in group
expansions. This option is
deprecated and will be removed from
a future version.
confCHECK_ALIASES CheckAliases [False] Check RHS of aliases when
running newaliases. Since this does
DNS lookups on every address, it can
slow down the alias rebuild process
considerably on large alias files.
confOLD_STYLE_HEADERS* OldStyleHeaders [True] Assume that headers without
special chars are old style.
confPRIVACY_FLAGS PrivacyOptions [authwarnings] Privacy flags.
confCOPY_ERRORS_TO PostmasterCopy [undefined] Address for additional
copies of all error messages.
confQUEUE_FACTOR QueueFactor [600000] Slope of queue-only function.
confQUEUE_FILE_MODE QueueFileMode [undefined] Default permissions for
queue files (octal). If not set,
sendmail uses 0600 unless its real
and effective uid are different in
which case it uses 0644.
confDONT_PRUNE_ROUTES DontPruneRoutes [False] Don't prune down route-addr
syntax addresses to the minimum
possible.
confSAFE_QUEUE* SuperSafe [True] Commit all messages to disk
before forking.
confTO_INITIAL Timeout.initial [5m] The timeout waiting for a response
on the initial connect.
confTO_CONNECT Timeout.connect [0] The timeout waiting for an initial
connect() to complete. This can only
shorten connection timeouts; the kernel
silently enforces an absolute maximum
(which varies depending on the system).
confTO_ICONNECT Timeout.iconnect
[undefined] Like Timeout.connect, but
applies only to the very first attempt
to connect to a host in a message.
This allows a single very fast pass
followed by more careful delivery
attempts in the future.
confTO_ACONNECT Timeout.aconnect
[0] The overall timeout waiting for
all connection for a single delivery
attempt to succeed. If 0, no overall
limit is applied.
confTO_HELO Timeout.helo [5m] The timeout waiting for a response
to a HELO or EHLO command.
confTO_MAIL Timeout.mail [10m] The timeout waiting for a
response to the MAIL command.
confTO_RCPT Timeout.rcpt [1h] The timeout waiting for a response
to the RCPT command.
confTO_DATAINIT Timeout.datainit
[5m] The timeout waiting for a 354
response from the DATA command.
confTO_DATABLOCK Timeout.datablock
[1h] The timeout waiting for a block
during DATA phase.
confTO_DATAFINAL Timeout.datafinal
[1h] The timeout waiting for a response
to the final "." that terminates a
message.
confTO_RSET Timeout.rset [5m] The timeout waiting for a response
to the RSET command.
confTO_QUIT Timeout.quit [2m] The timeout waiting for a response
to the QUIT command.
confTO_MISC Timeout.misc [2m] The timeout waiting for a response
to other SMTP commands.
confTO_COMMAND Timeout.command [1h] In server SMTP, the timeout
waiting for a command to be issued.
confTO_IDENT Timeout.ident [5s] The timeout waiting for a
response to an IDENT query.
confTO_FILEOPEN Timeout.fileopen
[60s] The timeout waiting for a file
(e.g., :include: file) to be opened.
confTO_LHLO Timeout.lhlo [2m] The timeout waiting for a response
to an LMTP LHLO command.
confTO_AUTH Timeout.auth [10m] The timeout waiting for a
response in an AUTH dialogue.
confTO_STARTTLS Timeout.starttls
[1h] The timeout waiting for a

[varies] Sets the resolver's
retransmission time interval (in
seconds). Sets both
Timeout.resolver.retrans.first and

a connection again without STARTTLS
after a TLS handshake failure.
confTRY_NULL_MX_LIST TryNullMXList [False] If this host is the best MX
for a host and other arrangements
haven't been made, try connecting
to the host directly; normally this
would be a config error.
confQUEUE_LA QueueLA [varies] Load average at which
queue-only function kicks in.
Default values is (8 * numproc)
where numproc is the number of
processors online (if that can be
determined).
confREFUSE_LA RefuseLA [varies] Load average at which

confMAX_QUEUE_AGE MaxQueueAge [undefined] If set to a value greater
than zero, entries in the queue
will be retried during a queue run
only if the individual retry time
has been reached which is doubled
for each attempt. The maximum retry
time is limited by the specified value.
confMIN_QUEUE_AGE MinQueueAge [0] The minimum amount of time a job
must sit in the queue between queue
runs. This allows you to set the
queue run interval low for better
responsiveness without trying all

systems that do not have a
system-defined switch.
confHOSTS_FILE HostsFile [/etc/hosts] The file to use when doing
"file" type access of hosts names.
confDIAL_DELAY DialDelay [0s] If a connection fails, wait this
long and try again. Zero means "don't
retry". This is to allow "dial on
demand" connections to have enough time
to complete a connection.
confNO_RCPT_ACTION NoRecipientAction
[none] What to do if there are no legal
recipient fields (To:, Cc: or Bcc:)
in the message. Legal values can
be "none" to just leave the
nonconforming message as is, "add-to"
to add a To: header with all the
known recipients (which may expose
blind recipients), "add-apparently-to"
to do the same but use Apparently-To:
instead of To: (strongly discouraged
in accordance with IETF standards),
"add-bcc" to add an empty Bcc:
header, or "add-to-undisclosed" to
add the header
``To: undisclosed-recipients:;''.
confSAFE_FILE_ENV SafeFileEnvironment
[undefined] If set, sendmail will do a
chroot() into this directory before
writing files.
confCOLON_OK_IN_ADDR ColonOkInAddr [True unless Configuration Level > 6]
If set, colons are treated as a regular
character in addresses. If not set,
they are treated as the introducer to
the RFC 822 "group" syntax. Colons are
handled properly in route-addrs. This
option defaults on for V5 and lower
configuration files.
confMAX_QUEUE_RUN_SIZE MaxQueueRunSize [0] If set, limit the maximum size of
any given queue run to this number of
entries. Essentially, this will stop
reading each queue directory after this
number of entries are reached; it does
_not_ pick the highest priority jobs,
so this should be as large as your
system can tolerate. If not set, there
is no limit.
confMAX_QUEUE_CHILDREN MaxQueueChildren
[undefined] Limits the maximum number
of concurrent queue runners active.
This is to keep system resources used
within a reasonable limit. Relates to
Queue Groups and ForkEachJob.
confMAX_RUNNERS_PER_QUEUE MaxRunnersPerQueue
[1] Only active when MaxQueueChildren
defined. Controls the maximum number
of queue runners (aka queue children)
active at the same time in a work
group. See also MaxQueueChildren.
confDONT_EXPAND_CNAMES DontExpandCnames
[False] If set, $[ ... $] lookups that
do DNS based lookups do not expand
CNAME records. This currently violates
the published standards, but the IETF
seems to be moving toward legalizing
this. For example, if "FTP.Foo.ORG"
is a CNAME for "Cruft.Foo.ORG", then
with this option set a lookup of
"FTP" will return "FTP.Foo.ORG"; if
clear it returns "Cruft.FOO.ORG". N.B.
you may not see any effect until your
downstream neighbors stop doing CNAME
lookups as well.
confFROM_LINE UnixFromLine [From $g $d] The From_ line used
when sending to files or programs.
confSINGLE_LINE_FROM_HEADER SingleLineFromHeader
[False] From: lines that have
embedded newlines are unwrapped
onto one line.
confALLOW_BOGUS_HELO AllowBogusHELO [False] Allow HELO SMTP command that
does not include a host name.
confMUST_QUOTE_CHARS MustQuoteChars [.'] Characters to be quoted in a full
name phrase (@,;:\()[] are automatic).
confOPERATORS OperatorChars [.:%@!^/[]+] Address operator
characters.
confSMTP_LOGIN_MSG SmtpGreetingMessage
[$j Sendmail $v/$Z; $b]
The initial (spontaneous) SMTP
greeting message. The word "ESMTP"
will be inserted between the first and
second words to convince other
sendmails to try to speak ESMTP.
confDONT_INIT_GROUPS DontInitGroups [False] If set, the initgroups(3)
routine will never be invoked. You
might want to do this if you are
running NIS and you have a large group
map, since this call does a sequential
scan of the map; in a large site this
can cause your ypserv to run
essentially full time. If you set
this, agents run on behalf of users
will only have their primary
(/etc/passwd) group permissions.
confUNSAFE_GROUP_WRITES UnsafeGroupWrites
[True] If set, group-writable
:include: and .forward files are
considered "unsafe", that is, programs
and files cannot be directly referenced
from such files. World-writable files
are always considered unsafe.
Notice: this option is deprecated and
will be removed in future versions;
Set GroupWritableForwardFileSafe
and GroupWritableIncludeFileSafe in
DontBlameSendmail if required.
confCONNECT_ONLY_TO ConnectOnlyTo [undefined] override connection
address (for testing).
confCONTROL_SOCKET_NAME ControlSocketName
[undefined] Control socket for daemon
management.
confDOUBLE_BOUNCE_ADDRESS DoubleBounceAddress
[postmaster] If an error occurs when
sending an error message, send that
"double bounce" error message to this
address. If it expands to an empty
string, double bounces are dropped.
confSOFT_BOUNCE SoftBounce [False] If set, issue temporary errors
(4xy) instead of permanent errors
(5xy). This can be useful during
testing of a new configuration to
avoid erroneous bouncing of mails.
confDEAD_LETTER_DROP DeadLetterDrop [undefined] Filename to save bounce
messages which could not be returned
to the user or sent to postmaster.
If not set, the queue file will
be renamed.
confRRT_IMPLIES_DSN RrtImpliesDsn [False] Return-Receipt-To: header
implies DSN request.
confRUN_AS_USER RunAsUser [undefined] If set, become this user
when reading and delivering mail.
Causes all file reads (e.g., .forward
and :include: files) to be done as
this user. Also, all programs will
be run as this user, and all output
files will be written as this user.
confMAX_RCPTS_PER_MESSAGE MaxRecipientsPerMessage
[infinite] If set, allow no more than
the specified number of recipients in
an SMTP envelope. Further recipients
receive a 452 error code (i.e., they
are deferred for the next delivery
attempt).
confBAD_RCPT_THROTTLE BadRcptThrottle [infinite] If set and the specified
number of recipients in a single SMTP
transaction have been rejected, sleep
for one second after each subsequent
RCPT command in that transaction.
confDONT_PROBE_INTERFACES DontProbeInterfaces
[False] If set, sendmail will _not_
insert the names and addresses of any
local interfaces into class {w}
(list of known "equivalent" addresses).
If you set this, you must also include
some support for these addresses (e.g.,
in a mailertable entry) -- otherwise,
mail to addresses in this list will
bounce with a configuration error.
If set to "loopback" (without
quotes), sendmail will skip
loopback interfaces (e.g., "lo0").
confPID_FILE PidFile [system dependent] Location of pid
file.
confPROCESS_TITLE_PREFIX ProcessTitlePrefix
[undefined] Prefix string for the
process title shown on 'ps' listings.
confDONT_BLAME_SENDMAIL DontBlameSendmail
[safe] Override sendmail's file
safety checks. This will definitely
compromise system security and should
not be used unless absolutely
necessary.
confREJECT_MSG - [550 Access denied] The message
given if the access database contains
REJECT in the value portion.
confRELAY_MSG - [550 Relaying denied] The message
given if an unauthorized relaying
attempt is rejected.
confDF_BUFFER_SIZE DataFileBufferSize
[4096] The maximum size of a
memory-buffered data (df) file
before a disk-based file is used.
confXF_BUFFER_SIZE XScriptFileBufferSize
[4096] The maximum size of a
memory-buffered transcript (xf)
file before a disk-based file is
used.

+confAUTH_MECHANISMS AuthMechanisms [EXTERNAL GSSAPI KERBEROS_V4 DIGEST-MD5
CRAM-MD5] List of authentication
mechanisms for AUTH (separated by
spaces). The advertised list of
authentication mechanisms will be the
intersection of this list and the list
of available mechanisms as determined
by the Cyrus SASL library.
confAUTH_REALM AuthRealm [undefined] The authentication realm
that is passed to the Cyrus SASL
library. If no realm is specified,
$j is used. See KNOWNBUGS.
confDEF_AUTH_INFO DefaultAuthInfo [undefined] Name of file that contains
authentication information for
outgoing connections. This file must
contain the user id, the authorization
id, the password (plain text), the
realm to use, and the list of
mechanisms to try, each on a separate
line and must be readable by root (or
the trusted user) only. If no realm
is specified, $j is used. If no
mechanisms are given in the file,
AuthMechanisms is used. Notice: this
option is deprecated and will be
removed in future versions; it doesn't
work for the MSP since it can't read
the file. Use the authinfo ruleset
instead. See also the section SMTP
AUTHENTICATION.
confAUTH_OPTIONS AuthOptions [undefined] If this option is 'A'
then the AUTH= parameter for the
MAIL FROM command is only issued
when authentication succeeded.
See doc/op/op.me for more options
and details.
confAUTH_MAX_BITS AuthMaxBits [INT_MAX] Limit the maximum encryption
strength for the security layer in
SMTP AUTH (SASL). Default is
essentially unlimited.
confTLS_SRV_OPTIONS TLSSrvOptions If this option is 'V' no client
verification is performed, i.e.,
the server doesn't ask for a
certificate.
confSERVER_SSL_OPTIONS ServerSSLOptions [undefined] SSL related
options for server side. See
SSL_CTX_set_options(3) for a list.
confCLIENT_SSL_OPTIONS ClientSSLOptions [undefined] SSL related
options for client side. See
SSL_CTX_set_options(3) for a list.
confCIPHER_LIST CipherList [undefined] Cipher list for TLS.
See ciphers(1) for possible values.
confLDAP_DEFAULT_SPEC LDAPDefaultSpec [undefined] Default map
specification for LDAP maps. The
value should only contain LDAP
specific settings such as "-h host
-p port -d bindDN", etc. The
settings will be used for all LDAP
maps unless they are specified in
the individual map specification
('K' command).
confCACERT_PATH CACertPath [undefined] Path to directory with
certificates of CAs which must contain
their hashes as filenames or links.

is used when sendmail acts as
server.
confSERVER_KEY ServerKeyFile [undefined] File containing the
private key belonging to the server
cert.
confCLIENT_CERT ClientCertFile [undefined] File containing the
cert of the client, i.e., this cert
is used when sendmail acts as

DH parameters.
confDANE DANE [false] Enable DANE support.
confRAND_FILE RandFile [undefined] File containing random
data (use prefix file:) or the
name of the UNIX socket if EGD is
used (use prefix egd:). STARTTLS

[undefined] File where the
automatically selected key for
shared memory is stored.
confFAST_SPLIT FastSplit [1] If set to a value greater than
zero, the initial MX lookups on
addresses is suppressed when they
are sorted which may result in
faster envelope splitting. If the
mail is submitted directly from the
command line, then the value also
limits the number of processes to
deliver the envelopes.

See also the description of OSTYPE for some parameters that can be
tweaked (generally pathnames to mailers).
ClientPortOptions and DaemonPortOptions are special cases since multiple
clients/daemons can be defined. This can be done via
CLIENT_OPTIONS(`field1=value1,field2=value2,...')
DAEMON_OPTIONS(`field1=value1,field2=value2,...')
Note that multiple CLIENT_OPTIONS() commands (and therefore multiple
ClientPortOptions settings) are allowed in order to give settings for each
protocol family (e.g., one for Family=inet and one for Family=inet6). A
restriction placed on one family only affects outgoing connections on that
particular family.
If DAEMON_OPTIONS is not used, then the default is
DAEMON_OPTIONS(`Port=smtp, Name=MTA')
DAEMON_OPTIONS(`Port=587, Name=MSA, M=E')
If you use one DAEMON_OPTIONS macro, it will alter the parameters
of the first of these. The second will still be defaulted; it
represents a "Message Submission Agent" (MSA) as defined by RFC
2476 (see below). To turn off the default definition for the MSA,
use FEATURE(`no_default_msa') (see also FEATURES). If you use
additional DAEMON_OPTIONS macros, they will add additional daemons.
Example 1: To change the port for the SMTP listener, while
still using the MSA default, use
DAEMON_OPTIONS(`Port=925, Name=MTA')
Example 2: To change the port for the MSA daemon, while still
using the default SMTP port, use
FEATURE(`no_default_msa')
DAEMON_OPTIONS(`Name=MTA')
DAEMON_OPTIONS(`Port=987, Name=MSA, M=E')
Note that if the first of those DAEMON_OPTIONS lines were omitted, then
there would be no listener on the standard SMTP port.
Example 3: To listen on both IPv4 and IPv6 interfaces, use
DAEMON_OPTIONS(`Name=MTA-v4, Family=inet')
DAEMON_OPTIONS(`Name=MTA-v6, Family=inet6')
A "Message Submission Agent" still uses all of the same rulesets for
processing the message (and therefore still allows message rejection via
the check_* rulesets). In accordance with the RFC, the MSA will ensure
that all domains in envelope addresses are fully qualified if the message
is relayed to another MTA. It will also enforce the normal address syntax
rules and log error messages. Additionally, by using the M=a modifier you
can require authentication before messages are accepted by the MSA.
Notice: Do NOT use the 'a' modifier on a public accessible MTA! Finally,
the M=E modifier shown above disables ETRN as required by RFC 2476.
Mail filters can be defined using the INPUT_MAIL_FILTER() and MAIL_FILTER()
commands:
INPUT_MAIL_FILTER(`sample', `S=local:/var/run/f1.sock')
MAIL_FILTER(`myfilter', `S=inet:3333@localhost')
The INPUT_MAIL_FILTER() command causes the filter(s) to be called in the
same order they were specified by also setting confINPUT_MAIL_FILTERS. A
filter can be defined without adding it to the input filter list by using
MAIL_FILTER() instead of INPUT_MAIL_FILTER() in your .mc file.
Alternatively, you can reset the list of filters and their order by setting
confINPUT_MAIL_FILTERS option after all INPUT_MAIL_FILTER() commands in
your .mc file.
+----------------------------+
| MESSAGE SUBMISSION PROGRAM |
+----------------------------+
The purpose of the message submission program (MSP) is explained
in sendmail/SECURITY. This section contains a list of caveats and
a few hints how for those who want to tweak the default configuration
for it (which is installed as submit.cf).
Notice: do not add options/features to submit.mc unless you are
absolutely sure you need them. Options you may want to change
include:
- confTRUSTED_USERS, FEATURE(`use_ct_file'), and confCT_FILE for
avoiding X-Authentication warnings.
- confTIME_ZONE to change it from the default `USE_TZ'.
- confDELIVERY_MODE is set to interactive in msp.m4 instead
of the default background mode.
- FEATURE(stickyhost) and LOCAL_RELAY to send unqualified addresses
to the LOCAL_RELAY instead of the default relay.
- confRAND_FILE if you use STARTTLS and sendmail is not compiled with
the flag HASURANDOM.
The MSP performs hostname canonicalization by default. As also
explained in sendmail/SECURITY, mail may end up for various DNS
related reasons in the MSP queue. This problem can be minimized by
using
FEATURE(`nocanonify', `canonify_hosts')
define(`confDIRECT_SUBMISSION_MODIFIERS', `C')
See the discussion about nocanonify for possible side effects.
Some things are not intended to work with the MSP. These include
features that influence the delivery process (e.g., mailertable,
aliases), or those that are only important for a SMTP server (e.g.,
virtusertable, DaemonPortOptions, multiple queues). Moreover,
relaxing certain restrictions (RestrictQueueRun, permissions on
queue directory) or adding features (e.g., enabling prog/file mailer)
can cause security problems.
Other things don't work well with the MSP and require tweaking or
workarounds. For example, to allow for client authentication it
is not just sufficient to provide a client certificate and the
corresponding key, but it is also necessary to make the key group
(smmsp) readable and tell sendmail not to complain about that, i.e.,
define(`confDONT_BLAME_SENDMAIL', `GroupReadableKeyFile')
If the MSP should actually use AUTH then the necessary data
should be placed in a map as explained in SMTP AUTHENTICATION:
FEATURE(`authinfo', `DATABASE_MAP_TYPE /etc/mail/msp-authinfo')
/etc/mail/msp-authinfo should contain an entry like:
AuthInfo:127.0.0.1 "U:smmsp" "P:secret" "M:DIGEST-MD5"
The file and the map created by makemap should be owned by smmsp,
its group should be smmsp, and it should have mode 640. The database
used by the MTA for AUTH must have a corresponding entry.
Additionally the MTA must trust this authentication data so the AUTH=
part will be relayed on to the next hop. This can be achieved by
adding the following to your sendmail.mc file:
LOCAL_RULESETS
SLocal_trust_auth
R$* $: $&{auth_authen}
Rsmmsp $# OK
Note: the authentication data can leak to local users who invoke
the MSP with debug options or even with -v. For that reason either
an authentication mechanism that does not show the password in the
AUTH dialogue (e.g., DIGEST-MD5) or a different authentication
method like STARTTLS should be used.
feature/msp.m4 defines almost all settings for the MSP. Most of
those should not be changed at all. Some of the features and options
can be overridden if really necessary. It is a bit tricky to do
this, because it depends on the actual way the option is defined
in feature/msp.m4. If it is directly defined (i.e., define()) then
the modified value must be defined after
FEATURE(`msp')
If it is conditionally defined (i.e., ifdef()) then the desired
value must be defined before the FEATURE line in the .mc file.
To see how the options are defined read feature/msp.m4.
+--------------------------+
| FORMAT OF FILES AND MAPS |
+--------------------------+
Files that define classes, i.e., F{classname}, consist of lines
each of which contains a single element of the class. For example,
/etc/mail/local-host-names may have the following content:
my.domain
another.domain
Maps must be created using makemap(8) , e.g.,
makemap hash MAP < MAP
In general, a text file from which a map is created contains lines
of the form
key value
where 'key' and 'value' are also called LHS and RHS, respectively.
By default, the delimiter between LHS and RHS is a non-empty sequence
of white space characters.
+------------------+
| DIRECTORY LAYOUT |
+------------------+
Within this directory are several subdirectories, to wit:
m4 General support routines. These are typically
very important and should not be changed without
very careful consideration.
cf The configuration files themselves. They have
".mc" suffixes, and must be run through m4 to
become complete. The resulting output should
have a ".cf" suffix.
ostype Definitions describing a particular operating
system type. These should always be referenced
using the OSTYPE macro in the .mc file. Examples
include "bsd4.3", "bsd4.4", "sunos3.5", and
"sunos4.1".
domain Definitions describing a particular domain, referenced
using the DOMAIN macro in the .mc file. These are
site dependent; for example, "CS.Berkeley.EDU.m4"
describes hosts in the CS.Berkeley.EDU subdomain.
mailer Descriptions of mailers. These are referenced using
the MAILER macro in the .mc file.
sh Shell files used when building the .cf file from the
.mc file in the cf subdirectory.
feature These hold special orthogonal features that you might
want to include. They should be referenced using
the FEATURE macro.
hack Local hacks. These can be referenced using the HACK
macro. They shouldn't be of more than voyeuristic
interest outside the .Berkeley.EDU domain, but who knows?
siteconfig Site configuration -- e.g., tables of locally connected
UUCP sites.

| ADMINISTRATIVE DETAILS |
+------------------------+
The following sections detail usage of certain internal parts of the
sendmail.cf file. Read them carefully if you are trying to modify
the current model. If you find the above descriptions adequate, these
should be {boring, confusing, tedious, ridiculous} (pick one or more).

### SearchList: search a list of items in the access map
### Parameters:
### <exact tag> $| <mark:address> <mark:address> ... <>
dnl maybe we should have a @ (again) in front of the mark to
dnl avoid errorneous matches (with error messages?)
dnl if we can make sure that tag is always a single token
dnl then we can omit the delimiter $|, otherwise we need it
dnl to avoid errorneous matchs (first rule: D: if there
dnl is that mark somewhere in the list, it will be taken).
dnl moreover, we can do some tricks to enforce lookup with
dnl the tag only, e.g.:
### where "exact" is either "+" or "!":
### <+ TAG> lookup with and w/o tag
### <! TAG> lookup with tag
dnl Warning: + and ! should be in OperatorChars (otherwise there must be
dnl a blank between them and the tag.
### possible values for "mark" are:
### D: recursive host lookup (LookUpDomain)
dnl A: recursive address lookup (LookUpAddress) [not yet required]
### E: exact lookup, no modifications
### F: full lookup, try user+ext@domain and user@domain
### U: user lookup, try user+ext and user (input must have trailing @)
### return: <RHS of lookup> or <?> (not found)

# authenticated?
dnl we do not allow relaying for anyone who can present a cert

dnl CA in CertPath so we can authenticate users, we do not allow
dnl them to abuse our server (they might be easier to get hold of,
dnl but anyway).
dnl so here is the trick: if the verification succeeded
dnl we look up the cert issuer in the access map
dnl (maybe after extracting a part with a regular expression)
dnl if this returns RELAY we relay without further questions
dnl if it returns SUBJECT we perform a similar check on the
dnl cert subject.

# Acts as a preparser on /etc/mail/access_db to allow you to use address/bit

#
# If you have two overlapping CIDR blocks with conflicting actions

# make sure that the exceptions to the more general block are specified

#
# Modifications
# -------------
# 26 Jul 2001 Derek Balling (dredd@megacity.org)
# Now uses Net::CIDR because it makes life a lot easier.
#
# 5 Nov 2002 Richard Rognlie (richard@sendmail.com)
# Added code to deal with the prefix tags that may now be included in
# the access_db
#
# Added clarification in the notes for what to do if you have
# exceptions to a larger CIDR block.
#
# 26 Jul 2006 Richard Rognlie (richard@sendmail.com)
# Added code to strip "comments" (anything after a non-escaped #)
# # characters after a \ or within quotes (single and double) are
# left intact.
#
# e.g.
# From:1.2.3.4 550 Die spammer # spammed us 2006.07.26
# becomes
# From:1.2.3.4 550 Die spammer
#
# 3 August 2006
# Corrected a bug to have it handle the special case of "0.0.0.0/0"
# since Net::CIDR doesn't handle it properly.
#
# 27 April 2016
# Corrected IPv6 handling. Note that UseCompressedIPv6Addresses must
# be turned off for this to work; there are three reasons for this:
# 1) if the MTA uses compressed IPv6 addresses then CIDR 'cuts'
# in the compressed range *cannot* be matched, as the MTA simply
# won't look for them. E.g., there's no way to accurately
# match "IPv6:fe80::/64" when for the address "IPv6:fe80::54ad"
# the MTA doesn't lookup up "IPv6:fe80:0:0:0"
# 2) cidrexpand only generates uncompressed addresses, so CIDR
# 'cuts' to the right of the compressed range won't be matched
# either. Why doesn't it generate compressed address output?
# Oh, because:
# 3) compressed addresses are ambiguous when colon-groups are
# chopped off! You want an access map entry for
# IPv6:fe80::0:5420
# but not for
# IPv6:fe80::5420:1234
# ? Sorry, the former is really
# IPv6:fe80::5420
# which will also match the latter!
#
# 25 July 2016
# Since cidrexpand already requires UseCompressedIPv6Addresses to be
# turned off, it can also canonicalize non-CIDR IPv6 addresses to the
# format that sendmail looks up, expanding compressed addresses and
# trimming superfluous leading zeros.

.i Sendmail \u\s-2TM\s0\d
implements a general purpose internetwork mail routing facility
under the UNIX\(rg
operating system.
It is not tied to any one transport protocol \*-
its function may be likened to a crossbar switch,
relaying messages from one domain into another.
In the process,
it can do a limited amount of message header editing
to put the message into a format that is appropriate
for the receiving domain.
All of this is done under the control of a configuration file.
.pp
Due to the requirements of flexibility
for
.i sendmail ,
the configuration file can seem somewhat unapproachable.
However, there are only a few basic configurations
for most sites,
for which standard configuration files have been supplied.
Most other configurations
can be built by adjusting an existing configuration file
incrementally.
.pp
.i Sendmail
is based on
RFC 821 (Simple Mail Transport Protocol),
RFC 822 (Internet Mail Headers Format),
RFC 974 (MX routing),
RFC 1123 (Internet Host Requirements),
RFC 1413 (Identification server),
RFC 1652 (SMTP 8BITMIME Extension),
RFC 1869 (SMTP Service Extensions),
RFC 1870 (SMTP SIZE Extension),
RFC 1891 (SMTP Delivery Status Notifications),
RFC 1892 (Multipart/Report),
RFC 1893 (Enhanced Mail System Status Codes),
RFC 1894 (Delivery Status Notifications),
RFC 1985 (SMTP Service Extension for Remote Message Queue Starting),
RFC 2033 (Local Message Transmission Protocol),
RFC 2034 (SMTP Service Extension for Returning Enhanced Error Codes),
RFC 2045 (MIME),
RFC 2476 (Message Submission),
RFC 2487 (SMTP Service Extension for Secure SMTP over TLS),
RFC 2554 (SMTP Service Extension for Authentication),
RFC 2821 (Simple Mail Transfer Protocol),
RFC 2822 (Internet Message Format),
RFC 2852 (Deliver By SMTP Service Extension),
RFC 2920 (SMTP Service Extension for Command Pipelining),
and
RFC 7505 (A "Null MX" No Service Resource Record for Domains That Accept No Mail).
However, since
.i sendmail
is designed to work in a wider world,
in many cases it can be configured to exceed these protocols.
These cases are described herein.
.pp
Although
.i sendmail
is intended to run
without the need for monitoring,
it has a number of features
that may be used to monitor or adjust the operation
under unusual circumstances.
These features are described.
.pp
Section one describes how to do a basic
.i sendmail
installation.
Section two
explains the day-to-day information you should know
to maintain your mail system.
If you have a relatively normal site,
these two sections should contain sufficient information
for you to install
.i sendmail
and keep it happy.
Section three
has information regarding the command line arguments.
Section four
describes some parameters that may be safely tweaked.
Section five
contains the nitty-gritty information about the configuration
file.
This section is for masochists
and people who must write their own configuration file.
Section six
describes configuration that can be done at compile time.
The appendixes give a brief
but detailed explanation of a number of features
not described in the rest of the paper.
.bp 7
.sh 1 "BASIC INSTALLATION"
.pp
There are two basic steps to installing
.i sendmail .
First, you have to compile and install the binary.
If
.i sendmail
has already been ported to your operating system
that should be simple.
Second, you must build a run-time configuration file.
This is a file that
.i sendmail
reads when it starts up
that describes the mailers it knows about,
how to parse addresses,
how to rewrite the message header,
and the settings of various options.
Although the configuration file can be quite complex,
a configuration can usually be built
using an M4-based configuration language.
Assuming you have the standard
.i sendmail
distribution, see
.i cf/README
for further information.
.pp
The remainder of this section will describe the installation of
.i sendmail
assuming you can use one of the existing configurations
and that the standard installation parameters are acceptable.
All pathnames and examples
are given from the root of the
.i sendmail
subtree,
normally
.i /usr/src/usr.\*(SD/sendmail
on 4.4BSD-based systems.
.pp
Continue with the next section if you need/want to compile
.i sendmail
yourself.
If you have a running binary already on your system,
you should probably skip to section 1.2.
.sh 2 "Compiling Sendmail"
.pp
All
.i sendmail
source is in the
.i sendmail
subdirectory.
To compile sendmail,
.q cd
into the
.i sendmail
directory and type
.(b
\&./Build
.)b
This will leave the binary in an appropriately named subdirectory,
e.g.,
obj.BSD-OS.2.1.i386.
It works for multiple object versions
compiled out of the same directory.
.sh 3 "Tweaking the Build Invocation"
.pp
You can give parameters on the
.i Build
command.
In most cases these are only used when the
.i obj.*
directory is first created.
To restart from scratch, use
.i -c .
These commands include:
.nr ii 0.5i
.ip "\-L \fIlibdirs\fP"
A list of directories to search for libraries.
.ip "\-I \fIincdirs\fP"
A list of directories to search for include files.
.ip "\-E \fIenvar\fP=\fIvalue\fP"
Set an environment variable to an indicated
.i value
before compiling.
.ip "\-c"
Create a new
.i obj.*
tree before running.
.ip "\-f \fIsiteconfig\fP"
Read the indicated site configuration file.
If this parameter is not specified,
.i Build
includes
.i all
of the files
.i $BUILDTOOLS/Site/site.$oscf.m4
and
.i $BUILDTOOLS/Site/site.config.m4 ,
where $BUILDTOOLS is normally
.i \&../devtools
and $oscf is the same name as used on the
.i obj.*
directory.
See below for a description of the site configuration file.
.ip "\-S"
Skip auto-configuration.
.i Build
will avoid auto-detecting libraries if this is set.
All libraries and map definitions must be specified
in the site configuration file.
.lp
Most other parameters are passed to the
.i make
program; for details see
.i $BUILDTOOLS/README .
.sh 3 "Creating a Site Configuration File"
.\"XXX
.pp
See sendmail/README for various compilation flags that can be set,
and devtools/README for details how to set them.
.sh 3 "Tweaking the Makefile"
.pp
.\" .b "XXX This should all be in the Site Configuration File section."
.i Sendmail
supports two different formats
for the local (on disk) version of databases,
notably the
.i aliases
database.
At least one of these should be defined if at all possible.
.nr ii 1i
.ip CDB
Constant DataBase (tinycdb).
.ip NDBM
The ``new DBM'' format,
available on nearly all systems around today.
This was the preferred format prior to 4.4BSD.
It allows such complex things as multiple databases
and closing a currently open database.
.ip NEWDB
The Berkeley DB package.
If you have this, use it.
It allows
long records,
multiple open databases,
real in-memory caching,
and so forth.
You can define this in conjunction with
.sm NDBM ;
if you do,
old alias databases are read,
but when a new database is created it will be in NEWDB format.
As a nasty hack,
if you have NEWDB, NDBM, and NIS defined,
and if the alias file name includes the substring
.q /yp/ ,
.i sendmail
will create both new and old versions of the alias file
during a
.i newalias
command.
This is required because the Sun NIS/YP system
reads the DBM version of the alias file.
It's ugly as sin,
but it works.
.lp
If neither of these are defined,
.i sendmail
reads the alias file into memory on every invocation.
This can be slow and should be avoided.
There are also several methods for remote database access:
.ip LDAP
Lightweight Directory Access Protocol.
.ip NIS
Sun's Network Information Services (formerly YP).
.ip NISPLUS
Sun's NIS+ services.
.ip NETINFO
NeXT's NetInfo service.
.ip HESIOD
Hesiod service (from Athena).
.lp
Other compilation flags are set in
.i conf.h
and should be predefined for you
unless you are porting to a new environment.
For more options see
.i sendmail/README .
.sh 3 "Compilation and installation"
.pp
After making the local system configuration described above,
You should be able to compile and install the system.
The script
.q Build
is the best approach on most systems:
.(b
\&./Build
.)b
This will use
.i uname (1)
to create a custom Makefile for your environment.
.pp
If you are installing in the standard places,
you should be able to install using
.(b
\&./Build install
.)b
This should install the binary in
/usr/\*(SD
and create links from
/usr/\*(SB/newaliases
and
/usr/\*(SB/mailq
to
/usr/\*(SD/sendmail.
On most systems it will also format and install man pages.
Notice: as of version 8.12
.i sendmail
will no longer be installed set-user-ID root by default.
If you really want to use the old method, you can specify it as target:
.(b
\&./Build install-set-user-id
.)b
.sh 2 "Configuration Files"
.pp
.i Sendmail
cannot operate without a configuration file.
The configuration defines the mail delivery mechanisms understood at this site,
how to access them,
how to forward email to remote mail systems,
and a number of tuning parameters.
This configuration file is detailed
in the later portion of this document.
.pp
The
.i sendmail
configuration can be daunting at first.
The world is complex,
and the mail configuration reflects that.
The distribution includes an m4-based configuration package
that hides a lot of the complexity.
See
.i cf/README
for details.
.pp
Our configuration files are processed by
.i m4
to facilitate local customization;
the directory
.i cf
of the
.i sendmail
distribution directory
contains the source files.
This directory contains several subdirectories:
.nr ii 1i
.ip cf
Both site-dependent and site-independent descriptions of hosts.
These can be literal host names
(e.g.,
.q ucbvax.mc )
when the hosts are gateways
or more general descriptions
(such as
.q "generic-solaris2.mc"
as a general description of an SMTP-connected host
running Solaris 2.x.
Files ending
.b \&.mc
(``M4 Configuration'')
are the input descriptions;
the output is in the corresponding
.b \&.cf
file.
The general structure of these files is described below.
.ip domain
Site-dependent subdomain descriptions.
These are tied to the way your organization wants to do addressing.
For example,
.b domain/CS.Berkeley.EDU.m4
is our description for hosts in the CS.Berkeley.EDU subdomain.
These are referenced using the
.sm DOMAIN
.b m4
macro in the
.b \&.mc
file.
.ip feature
Definitions of specific features that some particular host in your site
might want.
These are referenced using the
.sm FEATURE
.b m4
macro.
An example feature is
use_cw_file
(which tells
.i sendmail
to read an /etc/mail/local-host-names file on startup
to find the set of local names).
.ip hack
Local hacks, referenced using the
.sm HACK
.b m4
macro.
Try to avoid these.
The point of having them here is to make it clear that they smell.
.ip m4
Site-independent
.i m4 (1)
include files that have information common to all configuration files.
This can be thought of as a
.q #include
directory.
.ip mailer
Definitions of mailers,
referenced using the
.sm MAILER
.b m4
macro.
The mailer types that are known in this distribution are
fax,
local,
smtp,
uucp,
and usenet.
For example, to include support for the UUCP-based mailers,
use
.q MAILER(uucp) .
.ip ostype
Definitions describing various operating system environments
(such as the location of support files).
These are referenced using the
.sm OSTYPE
.b m4
macro.
.ip sh
Shell files used by the
.b m4
build process.
You shouldn't have to mess with these.
.ip siteconfig
Local UUCP connectivity information.
This directory has been supplanted by the mailertable feature;
any new configurations should use that feature to do UUCP
(and other) routing.
The use of this directory is deprecated.
.pp
If you are in a new domain
(e.g., a company),
you will probably want to create a
cf/domain
file for your domain.
This consists primarily of relay definitions
and features you want enabled site-wide:
for example, Berkeley's domain definition
defines relays for
BitNET
and UUCP.
These are specific to Berkeley,
and should be fully-qualified internet-style domain names.
Please check to make certain they are reasonable for your domain.
.pp
Subdomains at Berkeley are also represented in the
cf/domain
directory.
For example,
the domain
CS.Berkeley.EDU
is the Computer Science subdomain,
EECS.Berkeley.EDU
is the Electrical Engineering and Computer Sciences subdomain,
and
S2K.Berkeley.EDU
is the Sequoia 2000 subdomain.
You will probably have to add an entry to this directory
to be appropriate for your domain.
.pp
You will have to use or create
.b \&.mc
files in the
.i cf/cf
subdirectory for your hosts.
This is detailed in the
cf/README
file.
.sh 2 "Details of Installation Files"
.pp
This subsection describes the files that
comprise the
.i sendmail
installation.
.sh 3 "/usr/\*(SD/sendmail"
.pp
The binary for
.i sendmail
is located in /usr/\*(SD\**.
.(f
\**This is usually
/usr/sbin
on 4.4BSD and newer systems;
many systems install it in
/usr/lib.
I understand it is in /usr/ucblib
on System V Release 4.
.)f
It should be set-group-ID smmsp as described in
sendmail/SECURITY.
For security reasons,
/, /usr, and /usr/\*(SD
should be owned by root, mode 0755\**.
.(f
\**Some vendors ship them owned by bin;
this creates a security hole that is not actually related to
.i sendmail .
Other important directories that should have restrictive ownerships
and permissions are
/bin, /usr/bin, /etc, /etc/mail, /usr/etc, /lib, and /usr/lib.
.)f
.sh 3 "/etc/mail/sendmail.cf"
.pp
This is the main configuration file for
.i sendmail \**.
.(f
\**Actually, the pathname varies depending on the operating system;
/etc/mail is the preferred directory.
Some older systems install it in
.b /usr/lib/sendmail.cf ,
and I've also seen it in
.b /usr/ucblib .
If you want to move this file,
add -D_PATH_SENDMAILCF=\e"/file/name\e"
to the flags passed to the C compiler.
Moving this file is not recommended:
other programs and scripts know of this location.
.)f
This is one of the two non-library file names compiled into
.i sendmail \**,
the other is /etc/mail/submit.cf.
.(f
\**The system libraries can reference other files;
in particular, system library subroutines that
.i sendmail
calls probably reference
.i /etc/passwd
and
.i /etc/resolv.conf .
.)f
.pp
The configuration file is normally created
using the distribution files described above.
If you have a particularly unusual system configuration
you may need to create a special version.
The format of this file is detailed in later sections
of this document.
.sh 3 "/etc/mail/submit.cf"
.pp
This is the configuration file for
.i sendmail
when it is used for initial mail submission, in which case
it is also called ``Mail Submission Program'' (MSP)
in contrast to ``Mail Transfer Agent'' (MTA).
Starting with version 8.12,
.i sendmail
uses one of two different configuration files based on its operation mode
(or the new
.b \-A
option).
For initial mail submission, i.e., if one of the options
.b \-bm
(default),
.b \-bs ,
or
.b \-t
is specified, submit.cf is used (if available),
for other operations sendmail.cf is used.
Details can be found in
.i sendmail/SECURITY .
submit.cf is shipped with sendmail (in cf/cf/) and is installed by default.
If changes to the configuration need to be made, start with
cf/cf/submit.mc and follow the instruction in cf/README.
.sh 3 "/usr/\*(SB/newaliases"
.pp
The
.i newaliases
command should just be a link to
.i sendmail :
.(b
rm \-f /usr/\*(SB/newaliases
ln \-s /usr/\*(SD/sendmail /usr/\*(SB/newaliases
.)b
This can be installed in whatever search path you prefer
for your system.
.sh 3 "/usr/\*(SB/hoststat"
.pp
The
.i hoststat
command should just be a link to
.i sendmail ,
in a fashion similar to
.i newaliases .
This command lists the status of the last mail transaction
with all remote hosts. The
.b \-v
flag will prevent the status display from being truncated.
It functions only when the
.b HostStatusDirectory
option is set.
.sh 3 "/usr/\*(SB/purgestat"
.pp
This command is also a link to
.i sendmail .
It flushes expired (Timeout.hoststatus) information that is stored in the
.b HostStatusDirectory
tree.
.sh 3 "/var/spool/mqueue"
.pp
The directory
.i /var/spool/mqueue
should be created to hold the mail queue.
This directory should be mode 0700
and owned by root.
.pp
The actual path of this directory
is defined by the
.b QueueDirectory
option of the
.i sendmail.cf
file.
To use multiple queues,
supply a value ending with an asterisk.
For example,
.i /var/spool/mqueue/qd*
will use all of the directories or symbolic links to directories
beginning with `qd' in
.i /var/spool/mqueue
as queue directories.
Do not change the queue directory structure
while sendmail is running.
.pp
If these directories have subdirectories or symbolic links to directories
named `qf', `df', and `xf', then these will be used for the different
queue file types.
That is, the data files are stored in the `df' subdirectory,
the transcript files are stored in the `xf' subdirectory, and
all others are stored in the `qf' subdirectory.
.pp
If shared memory support is compiled in,
.i sendmail
stores the available diskspace in a shared memory segment
to make the values readily available to all children without
incurring system overhead.
In this case, only the daemon updates the data;
i.e., the sendmail daemon creates the shared memory segment
and deletes it if it is terminated.
To use this,
.i sendmail
must have been compiled with support for shared memory
(-DSM_CONF_SHM)
and the option
.b SharedMemoryKey
must be set.
Notice: do not use the same key for
.i sendmail
invocations with different queue directories
or different queue group declarations.
Access to shared memory is not controlled by locks,
i.e., there is a race condition when data in the shared memory is updated.
However, since operation of
.i sendmail
does not rely on the data in the shared memory, this does not negatively
influence the behavior.
.sh 3 "/var/spool/clientmqueue"
.pp
The directory
.i /var/spool/clientmqueue
should be created to hold the mail queue.
This directory should be mode 0770
and owned by user smmsp, group smmsp.
.pp
The actual path of this directory
is defined by the
.b QueueDirectory
option of the
.i submit.cf
file.
.sh 3 "/var/spool/mqueue/.hoststat"
.pp
This is a typical value for the
.b HostStatusDirectory
option,
containing one file per host
that this sendmail has chatted with recently.
It is normally a subdirectory of
.i mqueue .
.sh 3 "/etc/mail/aliases*"
.pp
The system aliases are held in
.q /etc/mail/aliases .
A sample is given in
.q sendmail/aliases
which includes some aliases which
.i must
be defined:
.(b
cp sendmail/aliases /etc/mail/aliases
.i "edit /etc/mail/aliases"
.)b
You should extend this file with any aliases that are apropos to your system.
.pp
Normally
.i sendmail
looks at a database version of the files,
stored either in
.q /etc/mail/aliases.dir
and
.q /etc/mail/aliases.pag
or
.q /etc/mail/aliases.db
depending on which database package you are using.
The actual path of this file
is defined in the
.b AliasFile
option of the
.i sendmail.cf
file.
.pp
The permissions of the alias file and the database versions
should be 0640 to prevent local denial of service attacks
as explained in the top level
.b README
in the sendmail distribution.
If the permissions 0640 are used, be sure that only trusted users belong
to the group assigned to those files. Otherwise, files should not even
be group readable.
.sh 3 "/etc/rc or /etc/init.d/sendmail"
.pp
It will be necessary to start up the
.i sendmail
daemon when your system reboots.
This daemon performs two functions:
it listens on the SMTP socket for connections
(to receive mail from a remote system)
and it processes the queue periodically
to insure that mail gets delivered when hosts come up.
.pp
If necessary, add the following lines to
.q /etc/rc
(or
.q /etc/rc.local
as appropriate)
in the area where it is starting up the daemons
on a BSD-base system,
or on a System-V-based system
in one of the startup files, typically
.q /etc/init.d/sendmail :
.(b
if [ \-f /usr/\*(SD/sendmail \-a \-f /etc/mail/sendmail.cf ]; then
(cd /var/spool/mqueue; rm \-f xf*)
/usr/\*(SD/sendmail \-bd \-q30m &
echo \-n ' sendmail' >/dev/console
fi
.)b
The
.q cd
and
.q rm
commands insure that all transcript files have been removed;
extraneous transcript files may be left around
if the system goes down in the middle of processing a message.
The line that actually invokes
.i sendmail
has two flags:
.q \-bd
causes it to listen on the SMTP port,
and
.q \-q30m
causes it to run the queue every half hour.
.pp
Some people use a more complex startup script,
removing zero length qf/hf/Qf files and df files for which there is no
qf/hf/Qf file.
Note this is not advisable.
For example, see Figure 1
for an example of a complex script which does this clean up.
.(z
.hl
#!/bin/sh
# remove zero length qf/hf/Qf files
for qffile in qf* hf* Qf*
do
if [ \-r $qffile ]
then
if [ ! \-s $qffile ]
then
echo \-n " <zero: $qffile>" > /dev/console
rm \-f $qffile
fi
fi
done
# rename tf files to be qf if the qf does not exist
for tffile in tf*
do
qffile=`echo $tffile | sed 's/t/q/'`
if [ \-r $tffile \-a ! \-f $qffile ]
then
echo \-n " <recovering: $tffile>" > /dev/console
mv $tffile $qffile
else
if [ \-f $tffile ]
then
echo \-n " <extra: $tffile>" > /dev/console
rm \-f $tffile
fi
fi
done
# remove df files with no corresponding qf/hf/Qf files
for dffile in df*
do
qffile=`echo $dffile | sed 's/d/q/'`
hffile=`echo $dffile | sed 's/d/h/'`
Qffile=`echo $dffile | sed 's/d/Q/'`
if [ \-r $dffile \-a ! \-f $qffile \-a ! \-f $hffile \-a ! \-f $Qffile ]
then
echo \-n " <incomplete: $dffile>" > /dev/console
mv $dffile `echo $dffile | sed 's/d/D/'`
fi
done
# announce files that have been saved during disaster recovery
for xffile in [A-Z]f*
do
if [ \-f $xffile ]
then
echo \-n " <panic: $xffile>" > /dev/console
fi
done

.sh 3 "/etc/mail/helpfile"
.pp
This is the help file used by the SMTP
.b HELP
command.
It should be copied from
.q sendmail/helpfile :
.(b
cp sendmail/helpfile /etc/mail/helpfile
.)b
The actual path of this file
is defined in the
.b HelpFile
option of the
.i sendmail.cf
file.
.sh 3 "/etc/mail/statistics"
.pp
If you wish to collect statistics
about your mail traffic,
you should create the file
.q /etc/mail/statistics :
.(b
cp /dev/null /etc/mail/statistics
chmod 0600 /etc/mail/statistics
.)b
This file does not grow.
It is printed with the program
.q mailstats/mailstats.c.
The actual path of this file
is defined in the
.b S
option of the
.i sendmail.cf
file.
.sh 3 "/usr/\*(SB/mailq"
.pp
If
.i sendmail
is invoked as
.q mailq,
it will simulate the
.b \-bp
flag
(i.e.,
.i sendmail
will print the contents of the mail queue;
see below).
This should be a link to /usr/\*(SD/sendmail.
.sh 3 "sendmail.pid"
.pp
.i sendmail
stores its current pid in the file specified by the
.b PidFile
option (default is _PATH_SENDMAILPID).
.i sendmail
uses
.b TempFileMode
(which defaults to 0600) as
the permissions of that file
to prevent local denial of service attacks
as explained in the top level
.b README
in the sendmail distribution.
If the file already exists, then it might be necessary to
change the permissions accordingly, e.g.,
.(b
chmod 0600 /var/run/sendmail.pid
.)b
Note that as of version 8.13, this file is unlinked when
.i sendmail
exits.
As a result of this change, a script such as the following,
which may have worked prior to 8.13, will no longer work:
.(b
# stop & start sendmail
PIDFILE=/var/run/sendmail.pid
kill `head -1 $PIDFILE`
`tail -1 $PIDFILE`
.)b
because it assumes that the pidfile will still exist even
after killing the process to which it refers.
Below is a script which will work correctly
on both newer and older versions:
.(b
# stop & start sendmail
PIDFILE=/var/run/sendmail.pid
pid=`head -1 $PIDFILE`
cmd=`tail -1 $PIDFILE`
kill $pid
$cmd
.)b
This is just an example script, it does not perform any error checks,
e.g., whether the pidfile exists at all.
.sh 3 "Map Files"
.pp
To prevent local denial of service attacks
as explained in the top level
.b README
in the sendmail distribution,
the permissions of map files created by
.i makemap
should be 0640.
The use of 0640 implies that only trusted users belong to the group
assigned to those files.
If those files already exist, then it might be necessary to
change the permissions accordingly, e.g.,
.(b
cd /etc/mail
chmod 0640 *.db *.pag *.dir
.)b
.sh 1 "NORMAL OPERATIONS"
.sh 2 "The System Log"
.pp
The system log is supported by the
.i syslogd \|(8)
program.
All messages from
.i sendmail
are logged under the
.sm LOG_MAIL
facility\**.
.(f
\**Except on Ultrix,
which does not support facilities in the syslog.
.)f
.sh 3 "Format"
.pp
Each line in the system log
consists of a timestamp,
the name of the machine that generated it
(for logging from several machines
over the local area network),
the word
.q sendmail: ,
and a message\**.
.(f
\**This format may vary slightly if your vendor has changed
the syntax.
.)f
Most messages are a sequence of
.i name \c
=\c
.i value
pairs.
.pp
The two most common lines are logged when a message is processed.
The first logs the receipt of a message;
there will be exactly one of these per message.
Some fields may be omitted if they do not contain interesting information.
Fields are:
.ip from
The envelope sender address.
.ip size
The size of the message in bytes.
.ip class
The class (i.e., numeric precedence) of the message.
.ip pri
The initial message priority (used for queue sorting).
.ip nrcpts
The number of envelope recipients for this message
(after aliasing and forwarding).
.ip msgid
The message id of the message (from the header).
.ip bodytype
The message body type (7BIT or 8BITMIME),
as determined from the envelope.
.ip proto
The protocol used to receive this message (e.g., ESMTP or UUCP)
.ip daemon
The daemon name from the
.b DaemonPortOptions
setting.
.ip relay
The machine from which it was received.
.lp
There is also one line logged per delivery attempt
(so there can be several per message if delivery is deferred
or there are multiple recipients).
Fields are:
.ip to
A comma-separated list of the recipients to this mailer.
.ip ctladdr
The ``controlling user'', that is, the name of the user
whose credentials we use for delivery.
.ip delay
The total delay between the time this message was received
and the current delivery attempt.
.ip xdelay
The amount of time needed in this delivery attempt
(normally indicative of the speed of the connection).
.ip mailer
The name of the mailer used to deliver to this recipient.
.ip relay
The name of the host that actually accepted (or rejected) this recipient.
.ip dsn
The enhanced error code (RFC 2034) if available.
.ip stat
The delivery status.
.lp
Not all fields are present in all messages;
for example, the relay is usually not listed for local deliveries.
.sh 3 "Levels"
.pp
If you have
.i syslogd \|(8)
or an equivalent installed,
you will be able to do logging.
There is a large amount of information that can be logged.
The log is arranged as a succession of levels.
At the lowest level
only extremely strange situations are logged.
At the highest level,
even the most mundane and uninteresting events
are recorded for posterity.
As a convention,
log levels under ten
are considered generally
.q useful;
log levels above 64
are reserved for debugging purposes.
Levels from 11\-64 are reserved for verbose information
that some sites might want.
.pp
A complete description of the log levels
is given in section ``Log Level''.
.sh 2 "Dumping State"
.pp
You can ask
.i sendmail
to log a dump of the open files
and the connection cache
by sending it a
.sm SIGUSR1
signal.
The results are logged at
.sm LOG_DEBUG
priority.
.sh 2 "The Mail Queues"
.pp
Mail messages may either be delivered immediately or be held for later
delivery.
Held messages are placed into a holding directory called a mail queue.
.pp
A mail message may be queued for these reasons:
.bu
If a mail message is temporarily undeliverable, it is queued
and delivery is attempted later.
If the message is addressed to multiple recipients, it is queued
only for those recipients to whom delivery is not immediately possible.
.bu
If the SuperSafe option is set to true,
all mail messages are queued while delivery is attempted.
.bu
If the DeliveryMode option is set to queue-only or defer,
all mail is queued, and no immediate delivery is attempted.
.bu
If the load average becomes higher than the value of the QueueLA option
and the
.b QueueFactor
(\c
.b q )
option divided by the difference in the current load average and the
.b QueueLA
option plus one
is less than the priority of the message,
messages are queued rather than immediately delivered.
.bu
One or more addresses are marked as expensive and delivery is postponed
until the next queue run or one or more address are marked as held via
mailer which uses the hold mailer flag.
.bu
The mail message has been marked as quarantined via a mail filter or
rulesets.
.sh 3 "Queue Groups and Queue Directories"
.pp
There are one or more mail queues.
Each mail queue belongs to a queue group.
There is always a default queue group that is called ``mqueue''
(which is where messages go by default unless otherwise specified).
The directory or directories which comprise the default queue group
are specified by the QueueDirectory option.
There are zero or more
additional named queue groups declared using the
.b Q
command in the configuration file.
.pp
By default, a queued message is placed in the queue group
associated with the first recipient in the recipient list.
A recipient address is mapped to a queue group as follows.
First, if there is a ruleset called ``queuegroup'',
and if this ruleset maps the address to a queue group name,
then that queue group is chosen.
That is, the argument for the ruleset is
the recipient address
(i.e., the address part of the resolved triple)
and the result should be
.b $#
followed by the name of a queue group.
Otherwise, if the mailer associated with the address specifies
a queue group, then that queue group is chosen.
Otherwise, the default queue group is chosen.
.pp
A message with multiple recipients will be split
if different queue groups are chosen
by the mapping of recipients to queue groups.
.pp
When a message is placed in a queue group, and the queue group has
more than one queue, a queue is selected randomly.
.pp
If a message with multiple recipients is placed into a queue group
with the 'r' option (maximum number of recipients per message)
set to a positive value
.i N ,
and if there are more than
.i N
recipients
in the message, then the message will be split into multiple messages,
each of which have at most
.i N
recipients.
.pp
Notice: if multiple queue groups are used, do
.b not
move queue files around, e.g., into a different queue directory.
This may have weird effects and can cause mail not to be delivered.
Queue files and directories should be treated as opaque
and should not be manipulated directly.
.sh 3 "Queue Runs"
.pp
.i sendmail
has two different ways to process the queue(s).
The first one is to start queue runners after certain intervals
(``normal'' queue runners),
the second one is to keep queue runner processes around
(``persistent'' queue runners).
How to select either of these types is discussed in the appendix
``COMMAND LINE FLAGS''.
Persistent queue runners have the advantage that no new processes
need to be spawned at certain intervals; they just sleep for
a specified time after they finished a queue run.
Another advantage of persistent queue runners is that only one process
belonging to a workgroup (a workgroup is a set of queue groups)
collects the data for a queue run
and then multiple queue runner may go ahead using that data.
This can significantly reduce the disk I/O necessary to read the
queue files compared to starting multiple queue runners directly.
Their disadvantage is that a new queue run is only started
after all queue runners belonging to a group finished their tasks.
In case one of the queue runners tries delivery to a slow recipient site
at the end of a queue run, the next queue run may be substantially delayed.
In general this should be smoothed out due to the distribution of
those slow jobs, however, for sites with small number of
queue entries this might introduce noticeable delays.
In general, persistent queue runners are only useful for
sites with big queues.
.sh 3 "Manual Intervention"
.pp
Under normal conditions the mail queue will be processed transparently.
However, you may find that manual intervention is sometimes necessary.
For example,
if a major host is down for a period of time
the queue may become clogged.
Although
.i sendmail
ought to recover gracefully when the host comes up,
you may find performance unacceptably bad in the meantime.
In that case you want to check the content of the queue
and manipulate it as explained in the next two sections.
.sh 3 "Printing the queue"
.pp
The contents of the queue(s) can be printed
using the
.i mailq
command
(or by specifying the
.b \-bp
flag to
.i sendmail ):
.(b
mailq
.)b
This will produce a listing of the queue id's,
the size of the message,
the date the message entered the queue,
and the sender and recipients.
If shared memory support is compiled in,
the flag
.b \-bP
can be used to print the number of entries in the queue(s),
provided a process updates the data.
However, as explained earlier, the output might be slightly wrong,
since access to the shared memory is not locked.
For example,
``unknown number of entries''
might be shown.
The internal counters are updated after each queue run
to the correct value again.
.sh 3 "Forcing the queue"
.pp
.i Sendmail
should run the queue automatically at intervals.
When using multiple queues,
a separate process will by default be created to
run each of the queues
unless the queue run is initiated by a user
with the verbose flag.
The algorithm is to read and sort the queue,
and then to attempt to process all jobs in order.
When it attempts to run the job,
.i sendmail
first checks to see if the job is locked.
If so, it ignores the job.
.pp
There is no attempt to insure that only one queue processor
exists at any time,
since there is no guarantee that a job cannot take forever
to process
(however,
.i sendmail
does include heuristics to try to abort jobs
that are taking absurd amounts of time;
technically, this violates RFC 821, but is blessed by RFC 1123).
Due to the locking algorithm,
it is impossible for one job to freeze the entire queue.
However,
an uncooperative recipient host
or a program recipient
that never returns
can accumulate many processes in your system.
Unfortunately,
there is no completely general way to solve this.
.pp
In some cases,
you may find that a major host going down
for a couple of days
may create a prohibitively large queue.
This will result in
.i sendmail
spending an inordinate amount of time
sorting the queue.
This situation can be fixed by moving the queue to a temporary place
and creating a new queue.
The old queue can be run later when the offending host returns to service.
.pp
To do this,
it is acceptable to move the entire queue directory:
.(b
cd /var/spool
mv mqueue omqueue; mkdir mqueue; chmod 0700 mqueue
.)b
You should then kill the existing daemon
(since it will still be processing in the old queue directory)
and create a new daemon.
.pp
To run the old mail queue, issue the following command:
.(b
/usr/\*(SD/sendmail \-C /etc/mail/queue.cf \-q
.)b
The
.b \-C
flag specifies an alternate configuration file
.b queue.cf
which should refer to the moved queue directory
.(b
O QueueDirectory=/var/spool/omqueue
.)b
and the
.b \-q
flag says to just run every job in the queue.
You can also specify the moved queue directory on the command line
.(b
/usr/\*(SD/sendmail \-oQ/var/spool/omqueue \-q
.)b
but this requires that you do not have
queue groups in the configuration file,
because those are not subdirectories of the moved directory.
See the section about ``Queue Group Declaration'' for details;
you most likely need a different configuration file to correctly deal
with this problem.
However, a proper configuration of queue groups should avoid
filling up queue directories, so you shouldn't run into
this problem.
If you have a tendency toward voyeurism,
you can use the
.b \-v
flag to watch what is going on.
.pp
When the queue is finally emptied,
you can remove the directory:
.(b
rmdir /var/spool/omqueue
.)b
.sh 3 "Quarantined Queue Items"
.pp
It is possible to "quarantine" mail messages,
otherwise known as envelopes.
Envelopes (queue files) are stored but not considered for delivery or
display unless the "quarantine" state of the envelope is undone or
delivery or display of quarantined items is requested.
Quarantined messages are tagged by using a different name for the queue
file, 'hf' instead of 'qf', and by adding the quarantine reason to the
queue file.
.pp
Delivery or display of quarantined items can be requested using the
.b \-qQ
flag to
.i sendmail
or
.i mailq .
Additionally, messages already in the queue can be quarantined or
unquarantined using the new
.b \-Q
flag to sendmail.
For example,
.(b
sendmail -Qreason -q[!][I|R|S][matchstring]
.)b
Quarantines the normal queue items matching the criteria specified by the
.b "-q[!][I|R|S][matchstring]"
using the reason given on the
.b \-Q
flag.
Likewise,
.(b
sendmail -qQ -Q[reason] -q[!][I|R|S|Q][matchstring]
.)b
Change the quarantine reason for the quarantined items matching the
criteria specified by the
.b "-q[!][I|R|S|Q][matchstring]"
using the reason given on the
.b \-Q
flag.
If there is no reason,
unquarantine the matching items and make them normal queue items.
Note that the
.b \-qQ
flag tells sendmail to operate on quarantined items instead of normal items.
.sh 2 "Disk Based Connection Information"
.pp
.i Sendmail
stores a large amount of information about each remote system it
has connected to in memory. It is possible to preserve some
of this information on disk as well, by using the
.b HostStatusDirectory
option, so that it may be shared between several invocations of
.i sendmail .
This allows mail to be queued immediately or skipped during a queue run if
there has been a recent failure in connecting to a remote machine.
Note: information about a remote system is stored in a file
whose pathname consists of the components of the hostname in reverse order.
For example, the information for
.b host.example.com
is stored in
.b com./example./host .
For top-level domains like
.b com
this can create a large number of subdirectories
which on some filesystems can exhaust some limits.
Moreover, the performance of lookups in directory with thousands of entries
can be fairly slow depending on the filesystem implementation.
.pp
Additionally enabling
.b SingleThreadDelivery
has the added effect of single-threading mail delivery to a destination.
This can be quite helpful
if the remote machine is running an SMTP server that is easily overloaded
or cannot accept more than a single connection at a time,
but can cause some messages to be punted to a future queue run.
It also applies to
.i all
hosts, so setting this because you have one machine on site
that runs some software that is easily overrun
can cause mail to other hosts to be slowed down.
If this option is set,
you probably want to set the
.b MinQueueAge
option as well and run the queue fairly frequently;
this way jobs that are skipped because another
.i sendmail
is talking to the same host will be tried again quickly
rather than being delayed for a long time.
.pp
The disk based host information is stored in a subdirectory of the
.b mqueue
directory called
.b \&.hoststat \**.
.(f
\**This is the usual value of the
.b HostStatusDirectory
option;
it can, of course, go anywhere you like in your filesystem.
.)f
Removing this directory and its subdirectories has an effect similar to
the
.i purgestat
command and is completely safe.
However,
.i purgestat
only removes expired (Timeout.hoststatus) data.
The information in these directories can
be perused with the
.i hoststat
command, which will indicate the host name, the last access, and the
status of that access.
An asterisk in the left most column indicates that a
.i sendmail
process currently has the host locked for mail delivery.
.pp
The disk based connection information is treated the same way as memory based
connection information for the purpose of timeouts.
By default, information about host failures is valid for 30 minutes.
This can be adjusted with
the
.b Timeout.hoststatus
option.
.pp
The connection information stored on disk may be expired at any time
with the
.i purgestat
command or by invoking sendmail with the
.b \-bH
switch.
The connection information may be viewed with the
.i hoststat
command or by invoking sendmail with the
.b \-bh
switch.
.sh 2 "The Service Switch"
.pp
The implementation of certain system services
such as host and user name lookup
is controlled by the service switch.
If the host operating system supports such a switch,
and sendmail knows about it,
.i sendmail
will use the native version.
Ultrix, Solaris, and DEC OSF/1 are examples of such systems\**.
.(f
\**HP-UX 10 has service switch support,
but since the APIs are apparently not available in the libraries
.i sendmail
does not use the native service switch in this release.
.)f
.pp
If the underlying operating system does not support a service switch
(e.g., SunOS 4.X, HP-UX, BSD)
then
.i sendmail
will provide a stub implementation.
The
.b ServiceSwitchFile
option points to the name of a file that has the service definitions.
Each line has the name of a service
and the possible implementations of that service.
For example, the file:
.(b
hosts dns files nis
aliases files nis
.)b
will ask
.i sendmail
to look for hosts in the Domain Name System first.
If the requested host name is not found, it tries local files,
and if that fails it tries NIS.
Similarly, when looking for aliases
it will try the local files first followed by NIS.
.pp
Notice: since
.i sendmail
must access MX records for correct operation, it will use
DNS if it is configured in the
.b ServiceSwitchFile
file.
Hence an entry like
.(b
hosts files dns
.)b
will not avoid DNS lookups even if a host can be found
in /etc/hosts.
.pp
+Note: in contrast to the
+.i sendmail
+stub implementation
+some operating systems do not preserve temporary failures.
+For example, if DNS returns a TRY_AGAIN status for this setup
+.(b
+hosts files dns myhostname
+.)b
+but myhostname does not find the requested entry,
+then a permanent error is returned to
+.i sendmail
+which obviously can cause problems,
+e.g., an immediate bounce instead of a deferral.
+.pp
Service switches are not completely integrated.
For example, despite the fact that the host entry listed in the above example
specifies to look in NIS,
on SunOS this won't happen because the system implementation of
.i gethostbyname \|(3)
doesn't understand this.
.sh 2 "The Alias Database"
.pp
After recipient addresses are read from the SMTP connection
or command line
they are parsed by ruleset 0,
which must resolve to a
{\c
.i mailer ,
.i host ,
.i address }
triple.
If the flags selected by the
.i mailer
include the
.b A
(aliasable) flag,
the
.i address
part of the triple is looked up as the key
(i.e., the left hand side)
in the alias database.
If there is a match, the address is deleted from the send queue
and all addresses on the right hand side of the alias
are added in place of the alias that was found.
This is a recursive operation,
so aliases found in the right hand side of the alias
are similarly expanded.
.pp
The alias database exists in two forms.
One is a text form,
maintained in the file
.i /etc/mail/aliases.
The aliases are of the form
.(b
name: name1, name2, ...
.)b
Only local names may be aliased;
e.g.,
.(b
eric@prep.ai.MIT.EDU: eric@CS.Berkeley.EDU
.)b
will not have the desired effect
(except on prep.ai.MIT.EDU,
and they probably don't want me)\**.
.(f
\**Actually, any mailer that has the `A' mailer flag set
will permit aliasing;
this is normally limited to the local mailer.
.)f
Aliases may be continued by starting any continuation lines
with a space or a tab or by putting a backslash directly before
the newline.
Blank lines and lines beginning with a sharp sign
(\c
.q # )
are comments.
.pp
The second form is processed by the
.i ndbm \|(3)\**
.(f
\**The
.i gdbm
package does not work.
.)f
or the Berkeley DB library.
This form is in the file
.i /etc/mail/aliases.db
(if using NEWDB)
or
.i /etc/mail/aliases.dir
and
.i /etc/mail/aliases.pag
(if using NDBM).
This is the form that
.i sendmail
actually uses to resolve aliases.
This technique is used to improve performance.
.pp
The control of search order is actually set by the service switch.
Essentially, the entry
.(b
O AliasFile=switch:aliases
.)b
is always added as the first alias entry;
also, the first alias file name without a class
(e.g., without
.q nis:
on the front)
will be used as the name of the file for a ``files'' entry
in the aliases switch.
For example, if the configuration file contains
.(b
O AliasFile=/etc/mail/aliases
.)b
and the service switch contains
.(b
aliases nis files nisplus
.)b
then aliases will first be searched in the NIS database,
then in /etc/mail/aliases,
then in the NIS+ database.
.pp
You can also use
.sm NIS -based
alias files.
For example, the specification:
.(b
O AliasFile=/etc/mail/aliases
O AliasFile=nis:mail.aliases@my.nis.domain
.)b
will first search the /etc/mail/aliases file
and then the map named
.q mail.aliases
in
.q my.nis.domain .
Warning: if you build your own
.sm NIS -based
alias files,
be sure to provide the
.b \-l
flag to
.i makedbm (8)
to map upper case letters in the keys to lower case;
otherwise, aliases with upper case letters in their names
won't match incoming addresses.
.pp
Additional flags can be added after the colon
exactly like a
.b K
line \(em for example:
.(b
O AliasFile=nis:\-N mail.aliases@my.nis.domain
.)b
will search the appropriate NIS map and always include null bytes in the key.
Also:
.(b
O AliasFile=nis:\-f mail.aliases@my.nis.domain
.)b
will prevent sendmail from downcasing the key before the alias lookup.
.sh 3 "Rebuilding the alias database"
.pp
The
.i hash
or
.i dbm
version of the database
may be rebuilt explicitly by executing the command
.(b
newaliases
.)b
This is equivalent to giving
.i sendmail
the
.b \-bi
flag:
.(b
/usr/\*(SD/sendmail \-bi
.)b
.pp
If you have multiple aliases databases specified,
the
.b \-bi
flag rebuilds all the database types it understands
(for example, it can rebuild NDBM databases but not NIS databases).
.sh 3 "Potential problems"
.pp
There are a number of problems that can occur
with the alias database.
They all result from a
.i sendmail
process accessing the DBM version
while it is only partially built.
This can happen under two circumstances:
One process accesses the database
while another process is rebuilding it,
or the process rebuilding the database dies
(due to being killed or a system crash)
before completing the rebuild.
.pp
Sendmail has three techniques to try to relieve these problems.
First, it ignores interrupts while rebuilding the database;
this avoids the problem of someone aborting the process
leaving a partially rebuilt database.
Second,
it locks the database source file during the rebuild \(em
but that may not work over NFS or if the file is unwritable.
Third,
at the end of the rebuild
it adds an alias of the form
.(b
@: @
.)b
(which is not normally legal).
Before
.i sendmail
will access the database,
it checks to insure that this entry exists\**.
.(f
\**The
.b AliasWait
option is required in the configuration
for this action to occur.
This should normally be specified.
.)f
.sh 3 "List owners"
.pp
If an error occurs on sending to a certain address,
say
.q \fIx\fP ,
.i sendmail
will look for an alias
of the form
.q owner-\fIx\fP
to receive the errors.
This is typically useful
for a mailing list
where the submitter of the list
has no control over the maintenance of the list itself;
in this case the list maintainer would be the owner of the list.
For example:
.(b
unix-wizards: eric@ucbarpa, wnj@monet, nosuchuser,
sam@matisse
owner-unix-wizards: unix-wizards-request
unix-wizards-request: eric@ucbarpa
.)b
would cause
.q eric@ucbarpa
to get the error that will occur
when someone sends to
unix-wizards
due to the inclusion of
.q nosuchuser
on the list.
.pp
List owners also cause the envelope sender address to be modified.
The contents of the owner alias are used if they point to a single user,
otherwise the name of the alias itself is used.
For this reason, and to obey Internet conventions,
the
.q owner-
address normally points at the
.q -request
address; this causes messages to go out with the typical Internet convention
of using ``\c
.i list -request''
as the return address.
.sh 2 "User Information Database"
.pp
This option is deprecated, use virtusertable and genericstable instead
as explained in
.i cf/README .
If you have a version of
.i sendmail
with the user information database
compiled in,
and you have specified one or more databases using the
.b U
option,
the databases will be searched for a
.i user :maildrop
entry.
If found, the mail will be sent to the specified address.
.sh 2 "Per-User Forwarding (.forward Files)"
.pp
As an alternative to the alias database,
any user may put a file with the name
.q .forward
in his or her home directory.
If this file exists,
.i sendmail
redirects mail for that user
to the list of addresses listed in the .forward file.
Note that aliases are fully expanded before forward files are referenced.
For example, if the home directory for user
.q mckusick
has a .forward file with contents:
.(b
mckusick@ernie
kirk@calder
.)b
then any mail arriving for
.q mckusick
will be redirected to the specified accounts.
.pp
Actually, the configuration file defines a sequence of filenames to check.
By default, this is the user's .forward file,
but can be defined to be more generally using the
.b ForwardPath
option.
If you change this,
you will have to inform your user base of the change;
\&.forward is pretty well incorporated into the collective subconscious.
.sh 2 "Special Header Lines"
.pp
Several header lines have special interpretations
defined by the configuration file.
Others have interpretations built into
.i sendmail
that cannot be changed without changing the code.
These built-ins are described here.
.sh 3 "Errors-To:"
.pp
If errors occur anywhere during processing,
this header will cause error messages to go to
the listed addresses.
This is intended for mailing lists.
.pp
The Errors-To: header was created in the bad old days
when UUCP didn't understand the distinction between an envelope and a header;
this was a hack to provide what should now be passed
as the envelope sender address.
It should go away.
It is only used if the
.b UseErrorsTo
option is set.
.pp
The Errors-To: header is officially deprecated
and will go away in a future release.
.sh 3 "Apparently-To:"
.pp
RFC 822 requires at least one recipient field
(To:, Cc:, or Bcc: line)
in every message.
If a message comes in with no recipients listed in the message
then
.i sendmail
will adjust the header based on the
.q NoRecipientAction
option.
One of the possible actions is to add an
.q "Apparently-To:"
header line for any recipients it is aware of.
.pp
The Apparently-To: header is non-standard
and is both deprecated and strongly discouraged.
.sh 3 "Precedence"
.pp
The Precedence: header can be used as a crude control of message priority.
It tweaks the sort order in the queue
and can be configured to change the message timeout values.
The precedence of a message also controls how
delivery status notifications (DSNs)
are processed for that message.
.sh 2 "IDENT Protocol Support"
.pp
.i Sendmail
supports the IDENT protocol as defined in RFC 1413.
Note that the RFC states
a client should wait at least 30 seconds for a response.
The default Timeout.ident is 5 seconds
as many sites have adopted the practice of dropping IDENT queries.
This has lead to delays processing mail.
Although this enhances identification
of the author of an email message
by doing a ``call back'' to the originating system to include
the owner of a particular TCP connection
in the audit trail
it is in no sense perfect;
a determined forger can easily spoof the IDENT protocol.
The following description is excerpted from RFC 1413:
.ba +5
.lp
6. Security Considerations
.lp
The information returned by this protocol is at most as trustworthy
as the host providing it OR the organization operating the host. For
example, a PC in an open lab has few if any controls on it to prevent
a user from having this protocol return any identifier the user
wants. Likewise, if the host has been compromised the information
returned may be completely erroneous and misleading.
.lp
The Identification Protocol is not intended as an authorization or
access control protocol. At best, it provides some additional
auditing information with respect to TCP connections. At worst, it
can provide misleading, incorrect, or maliciously incorrect
information.
.lp
The use of the information returned by this protocol for other than
auditing is strongly discouraged. Specifically, using Identification
Protocol information to make access control decisions - either as the
primary method (i.e., no other checks) or as an adjunct to other
methods may result in a weakening of normal host security.
.lp
An Identification server may reveal information about users,
entities, objects or processes which might normally be considered
private. An Identification server provides service which is a rough
analog of the CallerID services provided by some phone companies and
many of the same privacy considerations and arguments that apply to
the CallerID service apply to Identification. If you wouldn't run a
"finger" server due to privacy considerations you may not want to run
this protocol.
.ba
.lp
In some cases your system may not work properly with IDENT support
due to a bug in the TCP/IP implementation.
The symptoms will be that for some hosts
the SMTP connection will be closed
almost immediately.
If this is true or if you do not want to use IDENT,
you should set the IDENT timeout to zero;
this will disable the IDENT protocol.
.sh 1 "ARGUMENTS"
.pp
The complete list of arguments to
.i sendmail
is described in detail in Appendix A.
Some important arguments are described here.
.sh 2 "Queue Interval"
.pp
The amount of time between forking a process
to run through the queue is defined by the
.b \-q
flag.
If you run with delivery mode set to
.b i
or
.b b
this can be relatively large, since it will only be relevant
when a host that was down comes back up.
If you run in
.b q
mode it should be relatively short,
since it defines the maximum amount of time that a message
may sit in the queue.
(See also the MinQueueAge option.)
.pp
RFC 1123 section 5.3.1.1 says that this value should be at least 30 minutes
(although that probably doesn't make sense if you use ``queue-only'' mode).
.pp
Notice: the meaning of the interval time depends on whether normal
queue runners or persistent queue runners are used.
For the former, it is the time between subsequent starts of a queue run.
For the latter, it is the time sendmail waits after a persistent queue
runner has finished its work to start the next one.
Hence for persistent queue runners this interval should be very low,
typically no more than two minutes.
.sh 2 "Daemon Mode"
.pp
If you allow incoming mail over an IPC connection,
you should have a daemon running.
This should be set by your
.i /etc/rc
file using the
.b \-bd
flag.
The
.b \-bd
flag and the
.b \-q
flag may be combined in one call:
.(b
/usr/\*(SD/sendmail \-bd \-q30m
.)b
.pp
An alternative approach is to invoke sendmail from
.i inetd (8)
(use the
.b \-bs \ \-Am
flags to ask sendmail to speak SMTP on its standard input and output
and to run as MTA).
This works and allows you to wrap
.i sendmail
in a TCP wrapper program,
but may be a bit slower since the configuration file
has to be re-read on every message that comes in.
If you do this, you still need to have a
.i sendmail
running to flush the queue:
.(b
/usr/\*(SD/sendmail \-q30m
.)b
.sh 2 "Forcing the Queue"
.pp
In some cases you may find that the queue has gotten clogged for some reason.
You can force a queue run
using the
.b \-q
flag (with no value).
It is entertaining to use the
.b \-v
flag (verbose)
when this is done to watch what happens:
.(b
/usr/\*(SD/sendmail \-q \-v
.)b
.pp
You can also limit the jobs to those with a particular queue identifier,
recipient, sender, quarantine reason, or queue group
using one of the queue modifiers.
For example,
.q \-qRberkeley
restricts the queue run to jobs that have the string
.q berkeley
somewhere in one of the recipient addresses.
Similarly,
.q \-qSstring
limits the run to particular senders,
.q \-qIstring
limits it to particular queue identifiers, and
.q \-qQstring
limits it to particular quarantined reasons and only operated on
quarantined queue items, and
.q \-qGstring
limits it to a particular queue group.
The named queue group will be run even if it is set to have 0 runners.
You may also place an
.b !
before the
.b I
or
.b R
or
.b S
or
.b Q
to indicate that jobs are limited to not including a particular queue
identifier, recipient or sender.
For example,
.q \-q!Rseattle
limits the queue run to jobs that do not have the string
.q seattle
somewhere in one of the recipient addresses.
Should you need to terminate the queue jobs currently active then a SIGTERM
to the parent of the process (or processes) will cleanly stop the jobs.
.sh 2 "Debugging"
.pp
There are a fairly large number of debug flags
built into
.i sendmail .
Each debug flag has a category and a level.
Higher levels increase the level of debugging activity;
in most cases, this means to print out more information.
The convention is that levels greater than nine are
.q absurd,
i.e.,
they print out so much information that you wouldn't normally
want to see them except for debugging that particular piece of code.
.pp
You should
.b never
run a production sendmail server in debug mode.
Many of the debug flags will result in debug output being sent over the
SMTP channel unless the option
.b \-D
is used.
This will confuse many mail programs.
However, for testing purposes, it can be useful
when sending mail manually via
telnet to the port you are using while debugging.
.pp
A debug category is either an integer, like 42,
or a name, like ANSI.
You can specify a range of numeric debug categories
using the syntax 17-42.
You can specify a set of named debug categories using
a glob pattern like
.q sm_trace_* .
At present, only
.q *
and
.q ?
are supported in these glob patterns.
.pp
Debug flags are set using the
.b \-d
option;
the syntax is:
.(b
.ta \w'debug-categories:M 'u
debug-flag: \fB\-d\fP debug-list
debug-list: debug-option [ , debug-option ]*
debug-option: debug-categories [ . debug-level ]
debug-categories: integer | integer \- integer | category-pattern
category-pattern: [a-zA-Z_*?][a-zA-Z0-9_*?]*
debug-level: integer
.)b
where spaces are for reading ease only.
For example,
.(b
\-d12 Set category 12 to level 1
\-d12.3 Set category 12 to level 3
\-d3\-17 Set categories 3 through 17 to level 1
\-d3\-17.4 Set categories 3 through 17 to level 4
\-dANSI Set category ANSI to level 1
\-dsm_trace_*.3 Set all named categories matching sm_trace_* to level 3
.)b
For a complete list of the available debug flags
you will have to look at the code
and the
.i TRACEFLAGS
file in the sendmail distribution
(they are too dynamic to keep this document up to date).
For a list of named debug categories in the sendmail binary, use
.(b
ident /usr/sbin/sendmail | grep Debug
.)b
.sh 2 "Changing the Values of Options"
.pp
Options can be overridden using the
.b \-o
or
.b \-O
command line flags.
For example,
.(b
/usr/\*(SD/sendmail \-oT2m
.)b
sets the
.b T
(timeout) option to two minutes
for this run only;
the equivalent line using the long option name is
.(b
/usr/\*(SD/sendmail -OTimeout.queuereturn=2m
.)b
.pp
Some options have security implications.
Sendmail allows you to set these,
but relinquishes its set-user-ID or set-group-ID permissions thereafter\**.
.(f
\**That is, it sets its effective uid to the real uid;
thus, if you are executing as root,
as from root's crontab file or during system startup
the root permissions will still be honored.
.)f
.sh 2 "Trying a Different Configuration File"
.pp
An alternative configuration file
can be specified using the
.b \-C
flag; for example,
.(b
/usr/\*(SD/sendmail \-Ctest.cf \-oQ/tmp/mqueue
.)b
uses the configuration file
.i test.cf
instead of the default
.i /etc/mail/sendmail.cf.
If the
.b \-C
flag has no value
it defaults to
.i sendmail.cf
in the current directory.
.pp
.i Sendmail
gives up set-user-ID root permissions
(if it has been installed set-user-ID root)
when you use this flag, so it is common to use a publicly writable directory
(such as /tmp)
as the queue directory (QueueDirectory or Q option) while testing.
.sh 2 "Logging Traffic"
.pp
Many SMTP implementations do not fully implement the protocol.
For example, some personal computer based SMTPs
do not understand continuation lines in reply codes.
These can be very hard to trace.
If you suspect such a problem, you can set traffic logging using the
.b \-X
flag.
For example,
.(b
/usr/\*(SD/sendmail \-X /tmp/traffic \-bd
.)b
will log all traffic in the file
.i /tmp/traffic .
.pp
This logs a lot of data very quickly and should
.b NEVER
be used
during normal operations.
After starting up such a daemon,
force the errant implementation to send a message to your host.
All message traffic in and out of
.i sendmail ,
including the incoming SMTP traffic,
will be logged in this file.
.sh 2 "Testing Configuration Files"
.pp
When you build a configuration table,
you can do a certain amount of testing
using the
.q "test mode"
of
.i sendmail .
For example,
you could invoke
.i sendmail
as:
.(b
sendmail \-bt \-Ctest.cf
.)b
which would read the configuration file
.q test.cf
and enter test mode.
In this mode,
you enter lines of the form:
.(b
rwset address
.)b
where
.i rwset
is the rewriting set you want to use
and
.i address
is an address to apply the set to.
Test mode shows you the steps it takes
as it proceeds,
finally showing you the address it ends up with.
You may use a comma separated list of rwsets
for sequential application of rules to an input.
For example:
.(b
3,1,21,4 monet:bollard
.)b
first applies ruleset three to the input
.q monet:bollard.
Ruleset one is then applied to the output of ruleset three,
followed similarly by rulesets twenty-one and four.
.pp
If you need more detail,
you can also use the
.q \-d21
flag to turn on more debugging.
For example,
.(b
sendmail \-bt \-d21.99
.)b
turns on an incredible amount of information;
a single word address
is probably going to print out several pages worth of information.
.pp
You should be warned that internally,
.i sendmail
applies ruleset 3 to all addresses.
In test mode
you will have to do that manually.
For example, older versions allowed you to use
.(b
0 bruce@broadcast.sony.com
.)b
This version requires that you use:
.(b
3,0 bruce@broadcast.sony.com
.)b
.pp
As of version 8.7,
some other syntaxes are available in test mode:
.nr ii 1i
.ip \&.D\|x\|value
defines macro
.i x
to have the indicated
.i value .
This is useful when debugging rules that use the
.b $& \c
.i x
syntax.
.ip \&.C\|c\|value
adds the indicated
.i value
to class
.i c .
.ip \&=S\|ruleset
dumps the contents of the indicated ruleset.
.ip \-d\|debug-spec
is equivalent to the command-line flag.
.lp
Version 8.9 introduced more features:
.nr ii 1i
.ip ?
shows a help message.
.ip =M
display the known mailers.
.ip $m
print the value of macro m.
.ip $=c
print the contents of class c.
.ip /mx\ host
returns the MX records for `host'.
.ip /parse\ address
parse address, returning the value of
.i crackaddr ,
and the parsed address.
.ip /try\ mailer\ addr
rewrite address into the form it will have when
presented to the indicated mailer.
.ip /tryflags\ flags
set flags used by parsing. The flags can be `H' for
Header or `E' for Envelope, and `S' for Sender or `R'
for Recipient. These can be combined, `HR' sets
flags for header recipients.
.ip /canon\ hostname
try to canonify hostname.
.ip /map\ mapname\ key
look up `key' in the indicated `mapname'.
.ip /quit
quit address test mode.
.lp
.sh 2 "Persistent Host Status Information"
.pp
When
.b HostStatusDirectory
is enabled,
information about the status of hosts is maintained on disk
and can thus be shared between different instantiations of
.i sendmail .
The status of the last connection with each remote host
may be viewed with the command:
.(b
sendmail \-bh
.)b
This information may be flushed with the command:
.(b
sendmail \-bH
.)b
Flushing the information prevents new
.i sendmail
processes from loading it,
but does not prevent existing processes from using the status information
that they already have.
.sh 1 "TUNING"
.pp
There are a number of configuration parameters
you may want to change,
depending on the requirements of your site.
Most of these are set
using an option in the configuration file.
For example,
the line
.q "O Timeout.queuereturn=5d"
sets option
.q Timeout.queuereturn
to the value
.q 5d
(five days).
.pp
Most of these options have appropriate defaults for most sites.
However,
sites having very high mail loads may find they need to tune them
as appropriate for their mail load.
In particular,
sites experiencing a large number of small messages,
many of which are delivered to many recipients,
may find that they need to adjust the parameters
dealing with queue priorities.
.pp
All versions of
.i sendmail
prior to 8.7
had single character option names.
As of 8.7,
options have long (multi-character names).
Although old short names are still accepted,
most new options do not have short equivalents.
.pp
This section only describes the options you are most likely
to want to tweak;
read section
.\"XREF
5
for more details.
.sh 2 "Timeouts"
.pp
All time intervals are set
using a scaled syntax.
For example,
.q 10m
represents ten minutes, whereas
.q 2h30m
represents two and a half hours.
The full set of scales is:
.(b
.ta 4n
s seconds
m minutes
h hours
d days
w weeks
.)b
.sh 3 "Queue interval"
.pp
The argument to the
.b \-q
flag specifies how often a sub-daemon will run the queue.
This is typically set to between fifteen minutes and one hour.
If not set, or set to zero,
the queue will not be run automatically.
RFC 1123 section 5.3.1.1 recommends that this be at least 30 minutes.
Should you need to terminate the queue jobs currently active then a SIGTERM
to the parent of the process (or processes) will cleanly stop the jobs.
.sh 3 "Read timeouts"
.pp
Timeouts all have option names
.q Timeout.\fIsuboption\fP .
Most of these control SMTP operations.
The recognized
.i suboption s,
their default values, and the minimum values
allowed by RFC 2821 section 4.5.3.2 (or RFC 1123 section 5.3.2) are:
.nr ii 1i
.ip connect
The time to wait for an SMTP connection to open
(the
.i connect (2)
system call)
[0, unspecified].
If zero, uses the kernel default.
In no case can this option extend the timeout
longer than the kernel provides, but it can shorten it.
This is to get around kernels that provide an absurdly long connection timeout
(90 minutes in one case).
.ip iconnect
The same as
.i connect,
except it applies only to the initial attempt to connect to a host
for a given message
[0, unspecified].
The concept is that this should be very short (a few seconds);
hosts that are well connected and responsive will thus be serviced immediately.
Hosts that are slow will not hold up other deliveries in the initial
delivery attempt.
.ip aconnect
[0, unspecified]
The overall timeout waiting for all connection for a single delivery
attempt to succeed.
If 0, no overall limit is applied.
This can be used to restrict the total amount of time trying to connect to
a long list of host that could accept an e-mail for the recipient.
This timeout does not apply to
.b FallbackMXhost ,
i.e., if the time is exhausted, the
.b FallbackMXhost
is tried next.
.ip initial
The wait for the initial 220 greeting message
[5m, 5m].
.ip helo
The wait for a reply from a HELO or EHLO command
[5m, unspecified].
This may require a host name lookup, so
five minutes is probably a reasonable minimum.
.ip mail\(dg
The wait for a reply from a MAIL command
[10m, 5m].
.ip rcpt\(dg
The wait for a reply from a RCPT command
[1h, 5m].
This should be long
because it could be pointing at a list
that takes a long time to expand
(see below).
.ip datainit\(dg
The wait for a reply from a DATA command
[5m, 2m].
.ip datablock\(dg\(dd
The wait for reading a data block
(that is, the body of the message).
[1h, 3m].
This should be long because it also applies to programs
piping input to
.i sendmail
which have no guarantee of promptness.
.ip datafinal\(dg
The wait for a reply from the dot terminating a message.
[1h, 10m].
If this is shorter than the time actually needed
for the receiver to deliver the message,
duplicates will be generated.
This is discussed in RFC 1047.
.ip rset
The wait for a reply from a RSET command
[5m, unspecified].
.ip quit
The wait for a reply from a QUIT command
[2m, unspecified].
.ip misc
The wait for a reply from miscellaneous (but short) commands
such as NOOP (no-operation) and VERB (go into verbose mode).
[2m, unspecified].
.ip command\(dg\(dd
In server SMTP,
the time to wait for another command.
[1h, 5m].
.ip ident\(dd
The timeout waiting for a reply to an IDENT query
[5s\**, unspecified].
.(f
\**On some systems the default is zero to turn the protocol off entirely.
.)f
.ip lhlo
The wait for a reply to an LMTP LHLO command
[2m, unspecified].
.ip auth
The timeout for a reply in an SMTP AUTH dialogue
[10m, unspecified].
.ip starttls
The timeout for a reply to an SMTP STARTTLS command and the TLS handshake
[1h, unspecified].
.ip fileopen\(dd
The timeout for opening .forward and :include: files [60s, none].
.ip control\(dd
The timeout for a complete control socket transaction to complete [2m, none].
.ip hoststatus\(dd
How long status information about a host
(e.g., host down)
will be cached before it is considered stale
[30m, unspecified].
.ip resolver.retrans\(dd
The resolver's
retransmission time interval
(in seconds)
[varies].
Sets both
.i Timeout.resolver.retrans.first
and
.i Timeout.resolver.retrans.normal .
.ip resolver.retrans.first\(dd
The resolver's
retransmission time interval
(in seconds)
for the first attempt to
deliver a message
[varies].
.ip resolver.retrans.normal\(dd
The resolver's
retransmission time interval
(in seconds)
for all resolver lookups
except the first delivery attempt
[varies].
.ip resolver.retry\(dd
The number of times
to retransmit a resolver query.
Sets both
.i Timeout.resolver.retry.first
and
.i Timeout.resolver.retry.normal
[varies].
.ip resolver.retry.first\(dd
The number of times
to retransmit a resolver query
for the first attempt
to deliver a message
[varies].
.ip resolver.retry.normal\(dd
The number of times
to retransmit a resolver query
for all resolver lookups
except the first delivery attempt
[varies].
.lp
For compatibility with old configuration files,
if no
.i suboption
is specified,
all the timeouts marked with
.DG
(\(dg) are set to the indicated value.
All but those marked with
.DD
(\(dd) apply to client SMTP.
.pp
For example, the lines:
.(b
O Timeout.command=25m
O Timeout.datablock=3h
.)b
sets the server SMTP command timeout to 25 minutes
and the input data block timeout to three hours.
.sh 3 "Message timeouts"
.pp
After sitting in the queue for a few days,
an undeliverable message will time out.
This is to insure that at least the sender is aware
of the inability to send a message.
The timeout is typically set to five days.
It is sometimes considered convenient to also send a warning message
if the message is in the queue longer than a few hours
(assuming you normally have good connectivity;
if your messages normally took several hours to send
you wouldn't want to do this because it wouldn't be an unusual event).
These timeouts are set using the
.b Timeout.queuereturn
and
.b Timeout.queuewarn
options in the configuration file
(previously both were set using the
.b T
option).
.pp
If the message is submitted using the
.sm NOTIFY
.sm SMTP
extension,
warning messages will only be sent if
.sm NOTIFY=DELAY
is specified.
The queuereturn and queuewarn timeouts
can be further qualified with a tag based on the Precedence: field
in the message;
they must be one of
.q urgent
(indicating a positive non-zero precedence),
.q normal
(indicating a zero precedence), or
.q non-urgent
(indicating negative precedences).
For example, setting
.q Timeout.queuewarn.urgent=1h
sets the warning timeout for urgent messages only
to one hour.
The default if no precedence is indicated
is to set the timeout for all precedences.
If the message has a normal (default) precedence
and it is a delivery status notification (DSN),
.b Timeout.queuereturn.dsn
and
.b Timeout.queuewarn.dsn
can be used to give an alternative warn and return time
for DSNs.
The value "now" can be used for
-O Timeout.queuereturn
to return entries immediately during a queue run,
e.g., to bounce messages independent of their time in the queue.
.pp
Since these options are global,
and since you cannot know
.i "a priori"
how long another host outside your domain will be down,
a five day timeout is recommended.
This allows a recipient to fix the problem even if it occurs
at the beginning of a long weekend.
RFC 1123 section 5.3.1.1 says that this parameter
should be ``at least 4\-5 days''.
.pp
The
.b Timeout.queuewarn
value can be piggybacked on the
.b T
option by indicating a time after which
a warning message should be sent;
the two timeouts are separated by a slash.
For example, the line
.(b
OT5d/4h
.)b
causes email to fail after five days,
but a warning message will be sent after four hours.
This should be large enough that the message will have been tried
several times.
.sh 2 "Forking During Queue Runs"
.pp
By setting the
.b ForkEachJob
(\c
.b Y )
option,
.i sendmail
will fork before each individual message
while running the queue.
This option was used with earlier releases to prevent
.i sendmail
from consuming large amounts of memory.
It should no longer be necessary with
.i sendmail
8.12.
If the
.b ForkEachJob
option is not set,
.i sendmail
will keep track of hosts that are down during a queue run,
which can improve performance dramatically.
.pp
If the
.b ForkEachJob
option is set,
.i sendmail
cannot use connection caching.
.sh 2 "Queue Priorities"
.pp
Every message is assigned a priority when it is first instantiated,
consisting of the message size (in bytes)
offset by the message class
(which is determined from the Precedence: header)
times the
.q "work class factor"
and the number of recipients times the
.q "work recipient factor."
The priority is used to order the queue.
Higher numbers for the priority mean that the message will be processed later
when running the queue.
.pp
The message size is included so that large messages are penalized
relative to small messages.
The message class allows users to send
.q "high priority"
messages by including a
.q Precedence:
field in their message;
the value of this field is looked up in the
.b P
lines of the configuration file.
Since the number of recipients affects the amount of load a message presents
to the system,
this is also included into the priority.
.pp
The recipient and class factors
can be set in the configuration file using the
.b RecipientFactor
(\c
.b y )
and
.b ClassFactor
(\c
.b z )
options respectively.
They default to 30000 (for the recipient factor)
and 1800
(for the class factor).
The initial priority is:
.EQ
pri = msgsize - (class times bold ClassFactor) + (nrcpt times bold RecipientFactor)
.EN
(Remember, higher values for this parameter actually mean
that the job will be treated with lower priority.)
.pp
The priority of a job can also be adjusted each time it is processed
(that is, each time an attempt is made to deliver it)
using the
.q "work time factor,"
set by the
.b RetryFactor
(\c
.b Z )
option.
This is added to the priority,
so it normally decreases the precedence of the job,
on the grounds that jobs that have failed many times
will tend to fail again in the future.
The
.b RetryFactor
option defaults to 90000.
.sh 2 "Load Limiting"
.pp
.i Sendmail
can be asked to queue (but not deliver) mail
if the system load average gets too high using the
.b QueueLA
(\c
.b x )
option.
When the load average exceeds the value of the
.b QueueLA
option, the delivery mode is set to
.b q
(queue only) if the
.b QueueFactor
(\c
.b q )
option divided by the difference in the current load average and the
.b QueueLA
option plus one
is less than the priority of the message \(em
that is, the message is queued iff:
.EQ
pri > { bold QueueFactor } over { LA - { bold QueueLA } + 1 }
.EN
The
.b QueueFactor
option defaults to 600000,
so each point of load average is worth 600000 priority points
(as described above).
.pp
For drastic cases, the
.b RefuseLA
(\c
.b X )
option defines a load average at which
.i sendmail
will refuse to accept network connections.
Locally generated mail, i.e., mail which is not submitted via SMTP
(including incoming UUCP mail),
is still accepted.
Notice that the MSP submits mail to the MTA via SMTP, and hence
mail will be queued in the client queue in such a case.
Therefore it is necessary to run the client mail queue periodically.
.sh 2 "Resource Limits"
.pp
.i Sendmail
has several parameters to control resource usage.
Besides those mentioned in the previous section, there are at least
.b MaxDaemonChildren ,
.b ConnectionRateThrottle ,
.b MaxQueueChildren ,
and
.b MaxRunnersPerQueue .
The latter two limit the number of
.i sendmail
processes that operate on the queue.
These are discussed in the section
``Queue Group Declaration''.
The former two can be used to limit the number of incoming connections.
Their appropriate values depend on the host operating system and
the hardware, e.g., amount of memory.
In many situations it might be useful to set limits to prevent
to have too many
.i sendmail
processes, however, these limits can be abused to mount a
denial of service attack.
For example, if
.b MaxDaemonChildren=10
then an attacker needs to open only 10 SMTP sessions to the server,
leave them idle for most of the time,
and no more connections will be accepted.
If this option is set then the timeouts used in a SMTP session
should be lowered from their default values to
their minimum values as specified in RFC 2821 and listed in
section
.\"XREF
4.1.2.
.sh 2 "Measures against Denial of Service Attacks"
.pp
.i Sendmail
has some built-in measures against simple denial of service (DoS) attacks.
The SMTP server by default slows down if too many bad commands are
issued or if some commands are repeated too often within a session.
Details can be found in the source file
.b sendmail/srvrsmtp.c
by looking for the macro definitions of
.b MAXBADCOMMANDS ,
.b MAXNOOPCOMMANDS ,
.b MAXHELOCOMMANDS ,
.b MAXVRFYCOMMANDS ,
and
.b MAXETRNCOMMANDS .
If an SMTP command is issued more often than the corresponding
.b MAXcmdCOMMANDS
value, then the response is delayed exponentially,
starting with a sleep time of one second,
up to a maximum of four minutes (as defined by
.b MAXTIMEOUT ).
If the option
.b MaxDaemonChildren
is set to a value greater than zero,
then this could make a DoS attack even worse since it
keeps a connection open longer than necessary.
Therefore a connection is terminated with a 421 SMTP reply code
if the number of commands exceeds the limit by a factor of two and
.b MAXBADCOMMANDS
is set to a value greater than zero (the default is 25).
.sh 2 "Delivery Mode"
.pp
There are a number of delivery modes that
.i sendmail
can operate in,
set by the
.b DeliveryMode
(\c
.b d )
configuration option.
These modes
specify how quickly mail will be delivered.
Legal modes are:
.(b
.ta 4n
i deliver interactively (synchronously)
b deliver in background (asynchronously)
q queue only (don't deliver)
d defer delivery attempts (don't deliver)
.)b
There are tradeoffs.
Mode
.q i
gives the sender the quickest feedback,
but may slow down some mailers and
is hardly ever necessary.
Mode
.q b
delivers promptly but
can cause large numbers of processes
if you have a mailer that takes a long time to deliver a message.
Mode
.q q
minimizes the load on your machine,
but means that delivery may be delayed for up to the queue interval.
Mode
.q d
is identical to mode
.q q
except that it also prevents lookups in maps including the
.b -D
flag from working during the initial queue phase;
it is intended for ``dial on demand'' sites where DNS lookups
might cost real money.
Some simple error messages
(e.g., host unknown during the SMTP protocol)
will be delayed using this mode.
Mode
.q b
is the usual default.
.pp
If you run in mode
.q q
(queue only),
.q d
(defer),
or
.q b
(deliver in background)
.i sendmail
will not expand aliases and follow .forward files
upon initial receipt of the mail.
This speeds up the response to RCPT commands.
Mode
.q i
should not be used by the SMTP server.
.sh 2 "Log Level"
.pp
The level of logging can be set for
.i sendmail .
The default using a standard configuration is level 9.
The levels are approximately as follows
(some log types are using different level depending on various factors):
.nr ii 0.5i
.ip 0
Minimal logging.
.ip 1
Serious system failures and potential security problems.
.ip 2
Lost communications (network problems) and protocol failures.
.ip 3
Other serious failures, malformed addresses, transient forward/include
errors, connection timeouts.
.ip 4
Minor failures, out of date alias databases, connection rejections
via check_ rulesets.
.ip 5
Message collection statistics.
.ip 6
Creation of error messages,
VRFY and EXPN commands.
.ip 7
Delivery failures (host or user unknown, etc.).
.ip 8
Successful deliveries and alias database rebuilds.
.ip 9
Messages being deferred
(due to a host being down, etc.).
.ip 10
Database expansion (alias, forward, and userdb lookups)
and authentication information.
.ip 11
NIS errors and end of job processing.
.ip 12
Logs all SMTP connections.
.ip 13
Log bad user shells, files with improper permissions, and other
questionable situations.
.ip 14
Logs refused connections.
.ip 15
Log all incoming SMTP commands.
.ip 20
Logs attempts to run locked queue files.
These are not errors,
but can be useful to note if your queue appears to be clogged.
.ip 30
Lost locks (only if using lockf instead of flock).
.lp
Additionally,
values above 64 are reserved for extremely verbose debugging output.
No normal site would ever set these.
.sh 2 "File Modes"
.pp
The modes used for files depend on what functionality you want
and the level of security you require.
In many cases
.i sendmail
does careful checking of the modes
of files and directories
to avoid accidental compromise;
if you want to make it possible to have group-writable support files
you may need to use the
.b DontBlameSendmail
option to turn off some of these checks.
.sh 3 "To suid or not to suid?"
.pp
.i Sendmail
is no longer installed
set-user-ID to root.
sendmail/SECURITY
explains how to configure and install
.i sendmail
without set-user-ID to root but set-group-ID
which is the default configuration starting with 8.12.
.pp
The daemon usually runs as root, unless other measures are taken.
At the point where
.i sendmail
is about to
.i exec \|(2)
a mailer,
it checks to see if the userid is zero (root);
if so,
it resets the userid and groupid to a default
(set by the
.b U=
equate in the mailer line;
if that is not set, the
.b DefaultUser
option is used).
This can be overridden
by setting the
.b S
flag to the mailer
for mailers that are trusted
and must be called as root.
However,
this will cause mail processing
to be accounted
(using
.i sa \|(8))
to root
rather than to the user sending the mail.
.pp
A middle ground is to set the
.b RunAsUser
option.
This causes
.i sendmail
to become the indicated user as soon as it has done the startup
that requires root privileges
(primarily, opening the
.sm SMTP
socket).
If you use
.b RunAsUser ,
the queue directory
(normally
.i /var/spool/mqueue )
should be owned by that user,
and all files and databases
(including user
.i \&.forward
files,
alias files,
:include: files,
and external databases)
must be readable by that user.
Also, since sendmail will not be able to change its uid,
delivery to programs or files will be marked as unsafe,
e.g., undeliverable,
in
.i \&.forward ,
aliases,
and :include: files.
Administrators can override this by setting the
.b DontBlameSendmail
option to the setting
.b NonRootSafeAddr .
.b RunAsUser
is probably best suited for firewall configurations
that don't have regular user logins.
If the option is used on a system which performs local delivery,
then the local delivery agent must have the proper permissions
(i.e., usually set-user-ID root)
since it will be invoked by the
.b RunAsUser ,
not by root.
.sh 3 "Turning off security checks"
.pp
.i Sendmail
is very particular about the modes of files that it reads or writes.
For example, by default it will refuse to read most files
that are group writable
on the grounds that they might have been tampered with
by someone other than the owner;
it will even refuse to read files in group writable directories.
Also, sendmail will refuse to create a new aliases database in an
unsafe directory. You can get around this by manually creating the
database file as a trusted user ahead of time and then rebuilding the
aliases database with
.b newaliases .
.pp
If you are
.i quite
sure that your configuration is safe and you want
.i sendmail
to avoid these security checks,
you can turn off certain checks using the
.b DontBlameSendmail
option.
This option takes one or more names that disable checks.
In the descriptions that follow,
.q "unsafe directory"
means a directory that is writable by anyone other than the owner.
The values are:
.nr ii 0.5i
.ip Safe
No special handling.
.ip AssumeSafeChown
Assume that the
.i chown
system call is restricted to root.
Since some versions of UNIX permit regular users
to give away their files to other users on some filesystems,
.i sendmail
often cannot assume that a given file was created by the owner,
particularly when it is in a writable directory.
You can set this flag if you know that file giveaway is restricted
on your system.

Accept group-writable
.i \&.forward
files as safe for program and file delivery.
.ip GroupWritableIncludeFile
Allow group writable
.i :include:
files.
.ip GroupWritableIncludeFileSafe
Accept group-writable
.i :include:
files as safe for program and file delivery.
.ip GroupWritableSASLDBFile

.b HelpFile
option to be in an unsafe directory.
.ip IncludeFileInGroupWritableDirPath

This includes alias database files.
.ip LinkedServiceSwitchFileInWritableDir
Allow the service switch file to be a link
even if the directory is writable.
.ip MapInUnsafeDirPath
Allow maps (e.g.,
.i hash ,
.i btree ,
and
.i dbm
files)
in unsafe directories.
This includes alias database files.
.ip NonRootSafeAddr
Do not mark file and program deliveries as unsafe
if sendmail is not running with root privileges.
.ip RunProgramInUnsafeDirPath
Run programs that are in writable directories without logging a warning.
.ip RunWritableProgram
Run programs that are group- or world-writable without logging a warning.

Allow the status file to be a hard link.
.ip WriteStatsToSymLink
Allow the status file to be a symbolic link.
.sh 2 "Connection Caching"
.pp
When processing the queue,
.i sendmail
will try to keep the last few open connections open
to avoid startup and shutdown costs.
This only applies to IPC and LPC connections.
.pp
When trying to open a connection
the cache is first searched.
If an open connection is found, it is probed to see if it is still active
by sending a
.sm RSET
command.
It is not an error if this fails;
instead, the connection is closed and reopened.
.pp
Two parameters control the connection cache.
The
.b ConnectionCacheSize
(\c
.b k )
option defines the number of simultaneous open connections
that will be permitted.
If it is set to zero,
connections will be closed as quickly as possible.
The default is one.
This should be set as appropriate for your system size;
it will limit the amount of system resources that
.i sendmail
will use during queue runs.
Never set this higher than 4.
.pp
The
.b ConnectionCacheTimeout
(\c
.b K )
option specifies the maximum time that any cached connection
will be permitted to idle.
When the idle time exceeds this value
the connection is closed.
This number should be small
(under ten minutes)
to prevent you from grabbing too many resources
from other hosts.
The default is five minutes.
.sh 2 "Name Server Access"
.pp
Control of host address lookups is set by the
.b hosts
service entry in your service switch file.
If you are on a system that has built-in service switch support
(e.g., Ultrix, Solaris, or DEC OSF/1)
then your system is probably configured properly already.
Otherwise,
.i sendmail
will consult the file
.b /etc/mail/service.switch ,
which should be created.
.i Sendmail
only uses two entries:
.b hosts
and
.b aliases ,
although system routines may use other services
(notably the
.b passwd
service for user name lookups by
.i getpwname ).
.pp
However, some systems (such as SunOS 4.X)
will do DNS lookups
regardless of the setting of the service switch entry.
In particular, the system routine
.i gethostbyname (3)
is used to look up host names,
and many vendor versions try some combination of DNS, NIS,
and file lookup in /etc/hosts
without consulting a service switch.
.i Sendmail
makes no attempt to work around this problem,
and the DNS lookup will be done anyway.
If you do not have a nameserver configured at all,
such as at a UUCP-only site,
.i sendmail
will get a
.q "connection refused"
message when it tries to connect to the name server.
If the
.b hosts
switch entry has the service
.q dns
listed somewhere in the list,
.i sendmail
will interpret this to mean a temporary failure
and will queue the mail for later processing;
otherwise, it ignores the name server data.
.pp
The same technique is used to decide whether to do MX lookups.
If you want MX support, you
.i must
have
.q dns
listed as a service in the
.b hosts
switch entry.
.pp
The
.b ResolverOptions
(\c
.b I )
option allows you to tweak name server options.
The command line takes a series of flags as documented in
.i resolver (3)
(with the leading
.q RES_
deleted).
Each can be preceded by an optional `+' or `\(mi'.
For example, the line
.(b
O ResolverOptions=+AAONLY \(miDNSRCH
.)b
turns on the AAONLY (accept authoritative answers only)
and turns off the DNSRCH (search the domain path) options.
Most resolver libraries default DNSRCH, DEFNAMES, and RECURSE
flags on and all others off.
If NETINET6 is enabled, most libraries default to USE_INET6 as well.
You can also include
.q HasWildcardMX
to specify that there is a wildcard MX record matching your domain;
this turns off MX matching when canonifying names,
which can lead to inappropriate canonifications.
Use
.q WorkAroundBrokenAAAA
when faced with a broken nameserver that returns SERVFAIL
(a temporary failure)
on T_AAAA (IPv6) lookups
during hostname canonification.
Notice: it might be necessary to apply the same (or similar) options to
.i submit.cf
too.
.pp
Version level 1 configurations (see the section about
``Configuration Version Level'')
turn DNSRCH and DEFNAMES off when doing delivery lookups,
but leave them on everywhere else.
Version 8 of
.i sendmail
ignores them when doing canonification lookups
(that is, when using $[ ... $]),
and always does the search.
If you don't want to do automatic name extension,
don't call $[ ... $].
.pp
The search rules for $[ ... $] are somewhat different than usual.
If the name being looked up
has at least one dot, it always tries the unmodified name first.
If that fails, it tries the reduced search path,
and lastly tries the unmodified name
(but only for names without a dot,
since names with a dot have already been tried).
This allows names such as
``utc.CS''
to match the site in Czechoslovakia
rather than the site in your local Computer Science department.
It also prefers A and CNAME records over MX records \*-
that is, if it finds an MX record it makes note of it,
but keeps looking.
This way, if you have a wildcard MX record matching your domain,
it will not assume that all names match.
.pp
To completely turn off all name server access
on systems without service switch support
(such as SunOS 4.X)
you will have to recompile with
\-DNAMED_BIND=0
and remove \-lresolv from the list of libraries to be searched
when linking.
.sh 2 "Moving the Per-User Forward Files"
.pp
Some sites mount each user's home directory
from a local disk on their workstation,
so that local access is fast.
However, the result is that .forward file lookups
from a central mail server are slow.
In some cases,
mail can even be delivered on machines inappropriately
because of a file server being down.
The performance can be especially bad if you run the automounter.
.pp
The
.b ForwardPath
(\c
.b J )
option allows you to set a path of forward files.
For example, the config file line
.(b
O ForwardPath=/var/forward/$u:$z/.forward.$w
.)b
would first look for a file with the same name as the user's login
in /var/forward;
if that is not found (or is inaccessible)
the file
``.forward.\c
.i machinename ''
in the user's home directory is searched.
A truly perverse site could also search by sender
by using $r, $s, or $f.
.pp
If you create a directory such as /var/forward,
it should be mode 1777
(that is, the sticky bit should be set).
Users should create the files mode 0644.
Note that you must use the
ForwardFileInUnsafeDirPath and
ForwardFileInUnsafeDirPathSafe
flags with the
.b DontBlameSendmail
option to allow forward files in a world writable directory.
This might also be used as a denial of service attack
(users could create forward files for other users);
a better approach might be to create
/var/forward
mode 0755
and create empty files for each user,
owned by that user,
mode 0644.
If you do this, you don't have to set the DontBlameSendmail options
indicated above.
.sh 2 "Free Space"
.pp
On systems that have one of the system calls in the
.i statfs (2)
family
(including
.i statvfs
and
.i ustat ),
you can specify a minimum number of free blocks on the queue filesystem
using the
.b MinFreeBlocks
(\c
.b b )
option.
If there are fewer than the indicated number of blocks free
on the filesystem on which the queue is mounted
the SMTP server will reject mail
with the
452 error code.
This invites the SMTP client to try again later.
.pp
Beware of setting this option too high;
it can cause rejection of email
when that mail would be processed without difficulty.
.sh 2 "Maximum Message Size"
.pp
To avoid overflowing your system with a large message,
the
.b MaxMessageSize
option can be set to set an absolute limit
on the size of any one message.
This will be advertised in the ESMTP dialogue
and checked during message collection.
.sh 2 "Privacy Flags"
.pp
The
.b PrivacyOptions
(\c
.b p )
option allows you to set certain
``privacy''
flags.
Actually, many of them don't give you any extra privacy,
rather just insisting that client SMTP servers
use the HELO command
before using certain commands
or adding extra headers to indicate possible spoof attempts.
.pp
The option takes a series of flag names;
the final privacy is the inclusive or of those flags.
For example:
.(b
O PrivacyOptions=needmailhelo, noexpn
.)b
insists that the HELO or EHLO command be used before a MAIL command is accepted
and disables the EXPN command.
.pp
The flags are detailed in section
.\"XREF
5.6.
.sh 2 "Send to Me Too"
.pp
Beginning with version 8.10,
.i sendmail
includes by default the (envelope) sender in any list expansions.
For example, if
.q matt
sends to a list that contains
.q matt
as one of the members he will get a copy of the message.
If the
.b MeToo
option is set to
.sm FALSE
(in the configuration file or via the command line),
this behavior is changed, i.e.,
the (envelope) sender is excluded in list expansions.
.sh 1 "THE WHOLE SCOOP ON THE CONFIGURATION FILE"
.pp
This section describes the configuration file
in detail.
.pp
There is one point that should be made clear immediately:
the syntax of the configuration file
is designed to be reasonably easy to parse,
since this is done every time
.i sendmail
starts up,
rather than easy for a human to read or write.
The configuration file should be generated via the method described in
.b cf/README ,
it should not be edited directly unless someone is familiar
with the internals of the syntax described here and it is
not possible to achieve the desired result via the default method.
.pp
The configuration file is organized as a series of lines,
each of which begins with a single character
defining the semantics for the rest of the line.
Lines beginning with a space or a tab
are continuation lines
(although the semantics are not well defined in many places).
Blank lines and lines beginning with a sharp symbol
(`#')
are comments.
.sh 2 "R and S \*- Rewriting Rules"
.pp
The core of address parsing
are the rewriting rules.
These are an ordered production system.
.i Sendmail
scans through the set of rewriting rules
looking for a match on the left hand side
(LHS)
of the rule.
When a rule matches,
the address is replaced by the right hand side
(RHS)
of the rule.
.pp
There are several sets of rewriting rules.
Some of the rewriting sets are used internally
and must have specific semantics.
Other rewriting sets
do not have specifically assigned semantics,
and may be referenced by the mailer definitions
or by other rewriting sets.
.pp
The syntax of these two commands are:
.(b F
.b S \c
.i n
.)b
Sets the current ruleset being collected to
.i n .
If you begin a ruleset more than once
it appends to the old definition.
.(b F
.b R \c
.i lhs
.i rhs
.i comments
.)b
The
fields must be separated
by at least one tab character;
there may be embedded spaces
in the fields.
The
.i lhs
is a pattern that is applied to the input.
If it matches,
the input is rewritten to the
.i rhs .
The
.i comments
are ignored.
.pp
Macro expansions of the form
.b $ \c
.i x
are performed when the configuration file is read.
A literal
.b $
can be included using
.b $$ .
Expansions of the form
.b $& \c
.i x
are performed at run time using a somewhat less general algorithm.
This is intended only for referencing internally defined macros
such as
.b $h
that are changed at runtime.
.sh 3 "The left hand side"
.pp
The left hand side of rewriting rules contains a pattern.
Normal words are simply matched directly.
Metasyntax is introduced using a dollar sign.
The metasymbols are:
.(b
.ta \w'\fB$=\fP\fIx\fP 'u
\fB$*\fP Match zero or more tokens
\fB$+\fP Match one or more tokens
\fB$\-\fP Match exactly one token
\fB$=\fP\fIx\fP Match any phrase in class \fIx\fP
\fB$~\fP\fIx\fP Match any word not in class \fIx\fP
.)b
If any of these match,
they are assigned to the symbol
.b $ \c
.i n
for replacement on the right hand side,
where
.i n
is the index in the LHS.
For example,
if the LHS:
.(b
$\-:$+
.)b
is applied to the input:
.(b
UCBARPA:eric
.)b
the rule will match, and the values passed to the RHS will be:
.(b
.ta 4n
$1 UCBARPA
$2 eric
.)b
.pp
Additionally, the LHS can include
.b $@
to match zero tokens.
This is
.i not
bound to a
.b $ \c
.i n
on the RHS, and is normally only used when it stands alone
in order to match the null input.
.sh 3 "The right hand side"
.pp
When the left hand side of a rewriting rule matches,
the input is deleted and replaced by the right hand side.
Tokens are copied directly from the RHS
unless they begin with a dollar sign.
Metasymbols are:
.(b
.ta \w'$#mailer\0\0\0'u
\fB$\fP\fIn\fP Substitute indefinite token \fIn\fP from LHS
\fB$[\fP\fIname\fP\fB$]\fP Canonicalize \fIname\fP
\fB$(\fP\fImap key\fP \fB$@\fP\fIarguments\fP \fB$:\fP\fIdefault\fP \fB$)\fP
Generalized keyed mapping function
\fB$>\fP\fIn\fP \*(lqCall\*(rq ruleset \fIn\fP
\fB$#\fP\fImailer\fP Resolve to \fImailer\fP
\fB$@\fP\fIhost\fP Specify \fIhost\fP
\fB$:\fP\fIuser\fP Specify \fIuser\fP
.)b
.pp
The
.b $ \c
.i n
syntax substitutes the corresponding value from a
.b $+ ,
.b $\- ,
.b $* ,
.b $= ,
or
.b $~
match on the LHS.
It may be used anywhere.
.pp
A host name enclosed between
.b $[
and
.b $]
is looked up in the host database(s)
and replaced by the canonical name\**.
.(f
\**This is actually
completely equivalent
to $(host \fIhostname\fP$).
In particular, a
.b $:
default can be used.
.)f
For example,
.q $[ftp$]
might become
.q ftp.CS.Berkeley.EDU
and
.q $[[128.32.130.2]$]
would become
.q vangogh.CS.Berkeley.EDU.
.i Sendmail
recognizes its numeric IP address
without calling the name server
and replaces it with its canonical name.
.pp
The
.b $(
\&...
.b $)
syntax is a more general form of lookup;
it uses a named map instead of an implicit map.
If no lookup is found, the indicated
.i default
is inserted;
if no default is specified and no lookup matches,
the value is left unchanged.
The
.i arguments
are passed to the map for possible use.
.pp
The
.b $> \c
.i n
syntax
causes the remainder of the line to be substituted as usual
and then passed as the argument to ruleset
.i n .
The final value of ruleset
.i n
then becomes
the substitution for this rule.
The
.b $>
syntax expands everything after the ruleset name
to the end of the replacement string
and then passes that as the initial input to the ruleset.
Recursive calls are allowed.
For example,
.(b
$>0 $>3 $1
.)b
expands $1, passes that to ruleset 3, and then passes the result
of ruleset 3 to ruleset 0.
.pp
The
.b $#
syntax should
.i only
be used in ruleset zero,
a subroutine of ruleset zero,
or rulesets that return decisions (e.g., check_rcpt).
It causes evaluation of the ruleset to terminate immediately,
and signals to
.i sendmail
that the address has completely resolved.
The complete syntax for ruleset 0 is:
.(b
\fB$#\fP\fImailer\fP \fB$@\fP\fIhost\fP \fB$:\fP\fIuser\fP
.)b
This specifies the
{mailer, host, user}
3-tuple (triple) necessary to direct the mailer.
Note: the third element (
.i user
) is often also called
.i address
part.
If the mailer is local
the host part may be omitted\**.
.(f
\**You may want to use it for special
.q "per user"
extensions.
For example, in the address
.q jgm+foo@CMU.EDU ;
the
.q +foo
part is not part of the user name,
and is passed to the local mailer for local use.
.)f
The
.i mailer
must be a single word,
but the
.i host
and
.i user
may be multi-part.
If the
.i mailer
is the built-in IPC mailer,
the
.i host
may be a colon (or comma) separated list of hosts.
Each is separately MX expanded and the results are concatenated
to make (essentially) one long MX list.
Hosts separated by a comma have the same MX preference,
and for each colon separated host the MX preference is increased.
The
.i user
is later rewritten by the mailer-specific envelope rewriting set
and assigned to the
.b $u
macro.
As a special case, if the mailer specified has the
.b F=@
flag specified
and the first character of the
.b $:
value is
.q @ ,
the
.q @
is stripped off, and a flag is set in the address descriptor
that causes sendmail to not do ruleset 5 processing.
.pp
Normally, a rule that matches is retried,
that is,
the rule loops until it fails.
A RHS may also be preceded by a
.b $@
or a
.b $:
to change this behavior.
A
.b $@
prefix causes the ruleset to return with the remainder of the RHS
as the value.
A
.b $:
prefix causes the rule to terminate immediately,
but the ruleset to continue;
this can be used to avoid continued application of a rule.
The prefix is stripped before continuing.
.pp
The
.b $@
and
.b $:
prefixes may precede a
.b $>
spec;
for example:
.(b
.ta 8n
R$+ $: $>7 $1
.)b
matches anything,
passes that to ruleset seven,
and continues;
the
.b $:
is necessary to avoid an infinite loop.
.pp
Substitution occurs in the order described,
that is,
parameters from the LHS are substituted,
hostnames are canonicalized,
.q subroutines
are called,
and finally
.b $# ,
.b $@ ,
and
.b $:
are processed.
.sh 3 "Semantics of rewriting rule sets"
.pp
There are six rewriting sets
that have specific semantics.
Five of these are related as depicted by figure 1.

.pp
Ruleset three
should turn the address into
.q "canonical form."
This form should have the basic syntax:
.(b
local-part@host-domain-spec
.)b
Ruleset three
is applied by
.i sendmail
before doing anything with any address.
.pp
If no
.q @
sign is specified,
then the
host-domain-spec
.i may
be appended (box
.q D
in Figure 1)
from the
sender address
(if the
.b C
flag is set in the mailer definition
corresponding to the
.i sending
mailer).
.pp
Ruleset zero
is applied after ruleset three
to addresses that are going to actually specify recipients.
It must resolve to a
.i "{mailer, host, address}"
triple.
The
.i mailer
must be defined in the mailer definitions
from the configuration file.
The
.i host
is defined into the
.b $h
macro
for use in the argv expansion of the specified mailer.
Notice: since the envelope sender address will be used if
a delivery status notification must be send,
i.e., it may specify a recipient,
it is also run through ruleset zero.
If ruleset zero returns a temporary error
.b 4xy
then delivery is deferred.
This can be used to temporarily disable delivery,
e.g., based on the time of the day or other varying parameters.
It should not be used to quarantine e-mails.
.pp
Rulesets one and two
are applied to all sender and recipient addresses respectively.
They are applied before any specification
in the mailer definition.
They must never resolve.
.pp
Ruleset four is applied to all addresses
in the message.
It is typically used
to translate internal to external form.
.pp
In addition,
ruleset 5 is applied to all local addresses
(specifically, those that resolve to a mailer with the `F=5'
flag set)
that do not have aliases.
This allows a last minute hook for local names.
.sh 3 "Ruleset hooks"
.pp
A few extra rulesets are defined as
.q hooks
that can be defined to get special features.
They are all named rulesets.
The
.q check_*
forms all give accept/reject status;
falling off the end or returning normally is an accept,
and resolving to
.b $#error
is a reject or quarantine.
Quarantining is chosen by specifying
.b quarantine
in the second part of the mailer triplet:
.(b
$#error $@ quarantine $: Reason for quarantine
.)b
Many of these can also resolve to the special mailer name
.b $#discard ;
this accepts the message as though it were successful
but then discards it without delivery.
Note,
this mailer cannot be chosen as a mailer in ruleset 0.
Note also that all
.q check_*
rulesets have to deal with temporary failures, especially for map lookups,
themselves, i.e., they should return a temporary error code
or at least they should make a proper decision in those cases.
.sh 4 "check_relay"
.pp
The
.i check_relay
ruleset is called after a connection is accepted by the daemon.
It is not called when sendmail is started using the
.b \-bs
option.
It is passed
.(b
client.host.name $| client.host.address
.)b
where
.b $|
is a metacharacter separating the two parts.
This ruleset can reject connections from various locations.
Note that it only checks the connecting SMTP client IP address and hostname.
It does not check for third party message relaying.
The
.i check_rcpt
ruleset discussed below usually does third party message relay checking.
.sh 4 "check_mail"
.pp
The
.i check_mail
ruleset is passed the user name parameter of the
.sm "SMTP MAIL"
command.
It can accept or reject the address.
.sh 4 "check_rcpt"
.pp
The
.i check_rcpt
ruleset is passed the user name parameter of the
.sm "SMTP RCPT"
command.
It can accept or reject the address.
.sh 4 "check_data"
.pp
The
.i check_data
ruleset is called after the
.sm "SMTP DATA"
command, its parameter is the number of recipients.
It can accept or reject the command.
+.sh 4 "check_other"
+.pp
+The
+.i check_other
+ruleset is invoked for all unknown SMTP commands
+and for commands which do not have specific rulesets,
+e.g., NOOP and VERB.
+Internal checks, e.g., those explained in
+"Measures against Denial of Service Attacks",
+are performed first.
+The ruleset is passed
+.(b
+entire-SMTP-command $| SMTP-reply-first-digit
+.)b
+where
+.b $|
+is a metacharacter separating the two parts.
+For example,
+.(b
+VERB $| 2
+.)b
+reflects receiving the "VERB" SMTP command and the
+intent to return a "2XX" SMTP success reply.
+Alternatively,
+.(b
+JUNK TYPE=I $| 5
+.)b
+reflects receiving the unknown "JUNK TYPE=I" SMTP command
+and the intent to return a "5XX" SMTP failure reply.
+If the ruleset returns the SMTP reply code 421:
+.(b
+$#error $@ 4.7.0 $: 421 bad command
+.)b
+the session is terminated.
+Note: it is a bad idea to return the original command in the error text
+to the client as that might be abused for certain attacks.
+The ruleset cannot override a rejection triggered by the built-in rules.
.sh 4 "check_compat"
.pp
The
.i check_compat
ruleset is passed
.(b
sender-address $| recipient-address
.)b
where
.b $|
is a metacharacter separating the addresses.
It can accept or reject mail transfer between these two addresses
much like the
.i checkcompat()
function.
Note:
while other
.i check_*
rulesets are invoked during the SMTP mail receiption stage
(i.e., in the SMTP server),
.i check_compat
is invoked during the mail delivery stage.
.sh 4 "check_eoh"
.pp
The
.i check_eoh
ruleset is passed
.(b
number-of-headers $| size-of-headers
.)b
where
.b $|
is a metacharacter separating the numbers.
These numbers can be used for size comparisons with the
.b arith
map.
The ruleset is triggered after
all of the headers have been read.
It can be used to correlate information gathered
from those headers using the
.b macro
storage map.
One possible use is to check for a missing header.
For example:
.(b
.ta 1.5i
Kstorage macro
HMessage-Id: $>CheckMessageId
SCheckMessageId
# Record the presence of the header
R$* $: $(storage {MessageIdCheck} $@ OK $) $1
R< $+ @ $+ > $@ OK
R$* $#error $: 553 Header Error
Scheck_eoh
# Check the macro
R$* $: < $&{MessageIdCheck} >
# Clear the macro for the next message
R$* $: $(storage {MessageIdCheck} $) $1
# Has a Message-Id: header
R< $+ > $@ OK
# Allow missing Message-Id: from local mail
R$* $: < $&{client_name} >
R< > $@ OK
R< $=w > $@ OK
# Otherwise, reject the mail
R$* $#error $: 553 Header Error
.)b
Keep in mind the Message-Id: header is not a required header and
is not a guaranteed spam indicator.
This ruleset is an example and
should probably not be used in production.
.sh 4 "check_eom"
.pp
The
.i check_eom
ruleset is called after the end of a message,
its parameter is the message size.
It can accept or reject the message.
.sh 4 "check_etrn"
.pp
The
.i check_etrn
ruleset is passed the parameter of the
.sm "SMTP ETRN"
command.
It can accept or reject the command.
.sh 4 "check_expn"
.pp
The
.i check_expn
ruleset is passed the user name parameter of the
.sm "SMTP EXPN"
command.
It can accept or reject the address.
.sh 4 "check_vrfy"
.pp
The
.i check_vrfy
ruleset is passed the user name parameter of the
.sm "SMTP VRFY"
command.
It can accept or reject the command.
+.sh 4 "clt_features"
+.pp
+The
+.i clt_features
+ruleset is called with the server's host name
+when sendmail connects to it.
+This ruleset should return
+.b $#
+followed by a list of options
+(single characters delimited by white space).
+If the return value starts with anything else it is silently ignored.
+Generally upper case characters turn off a feature
+while lower case characters turn it on.
+Options `D'/`M' cause the client to not use DANE/MTA-STS,
+respectively,
+which is useful to interact with MTAs/MUs that have broken
+DANE/MTA-STS setups by simply not using it.
+Note:
+The
+.i d
+option in
+.i tls_clt_features
+to turn off DANE does not work when the server does not
+even offer STARTTLS.
.sh 4 "trust_auth"
.pp
The
.i trust_auth
ruleset is passed the AUTH= parameter of the
.sm "SMTP MAIL"
command.
It is used to determine whether this value should be
trusted. In order to make this decision, the ruleset
may make use of the various
.b ${auth_*}
macros.
If the ruleset does resolve to the
.q error
mailer the AUTH= parameter is not trusted and hence
not passed on to the next relay.
.sh 4 "tls_client"
.pp
The
.i tls_client
ruleset is called when sendmail acts as server, after a STARTTLS command
has been issued, and from
.i check_mail.
The parameter is the value of
.b ${verify}
and STARTTLS or MAIL, respectively.
If the ruleset does resolve to the
.q error
mailer, the appropriate error code is returned to the client.
.sh 4 "tls_server"
.pp
The
.i tls_server
ruleset is called when sendmail acts as client after a STARTTLS command
(should) have been issued.
The parameter is the value of
.b ${verify} .
If the ruleset does resolve to the
.q error
mailer, the connection is aborted
(treated as non-deliverable with a permanent or temporary error).
.sh 4 "tls_rcpt"
.pp
The
.i tls_rcpt
-ruleset is called each time before a RCPT TO command is sent.
+ruleset is called each time before a RCPT command is sent.
The parameter is the current recipient.
If the ruleset does resolve to the
.q error
-mailer, the RCPT TO command is suppressed
+mailer, the RCPT command is suppressed
(treated as non-deliverable with a permanent or temporary error).
This ruleset allows to require encryption or verification of
the recipient's MTA even if the mail is somehow redirected
to another host.
For example, sending mail to
.i luke@endmail.org
may get redirected to a host named
.i death.star
and hence the tls_server ruleset won't apply.
By introducing per recipient restrictions such attacks
(e.g., via DNS spoofing) can be made impossible.
See
.i cf/README
how this ruleset can be used.
.sh 4 "srv_features"
.pp
The
.i srv_features
ruleset is called with the connecting client's host name
when a client connects to sendmail.
This ruleset should return
.b $#
followed by a list of options (single characters
delimited by white space).
If the return value starts with anything else it is silently ignored.
Generally upper case characters turn off a feature
while lower case characters turn it on.
Option `S' causes the server not to offer STARTTLS,
which is useful to interact with MTAs/MUAs that have broken
STARTTLS implementations by simply not offering it.
`V' turns off the request for a client certificate during the TLS handshake.
Options `A' and `P' suppress SMTP AUTH and PIPELINING, respectively.
`c' is the equivalent to AuthOptions=p, i.e.,
it doesn't permit mechanisms susceptible to simple
passive attack (e.g., PLAIN, LOGIN), unless a security layer is active.
Option `l' requires SMTP AUTH for a connection.
Options 'B', 'D', 'E', and 'X' suppress SMTP VERB, DSN, ETRN, and EXPN,
respectively.
+If a client sends one of the (HTTP) commands GET, POST, CONNECT, or USER
+the connection is immediately terminated in the following cases:
+if sent as first command, if sent as first command after STARTTLS,
+or if the 'h' option is set.
.(b
.ta 9n
A Do not offer AUTH
a Offer AUTH (default)
B Do not offer VERB
b Offer VERB (default)
C Do not require security layer for
plaintext AUTH (default)
c Require security layer for plaintext AUTH
D Do not offer DSN
d Offer DSN (default)
E Do not offer ETRN
e Offer ETRN (default)
+h Terminate session after HTTP commands
L Do not require AUTH (default)
l Require AUTH
P Do not offer PIPELINING
p Offer PIPELINING (default)
S Do not offer STARTTLS
s Offer STARTTLS (default)
V Do not request a client certificate
v Request a client certificate (default)
X Do not offer EXPN
x Offer EXPN (default)
.)b
Note: the entries marked as ``(default)'' may require that some
configuration has been made, e.g., SMTP AUTH is only available if
properly configured.
Moreover, many options can be changed on a global basis via other
settings as explained in this document, e.g., via DaemonPortOptions.
.pp
The ruleset may return `$#temp' to indicate that there is a temporary
problem determining the correct features, e.g., if a map is unavailable.
In that case, the SMTP server issues a temporary failure and does not
accept email.
.sh 4 "try_tls"
.pp
The
.i try_tls
ruleset is called when sendmail connects to another MTA.
If the ruleset does resolve to the
.q error
mailer, sendmail does not try STARTTLS even if it is offered.
This is useful to deal with STARTTLS interoperability issues
by simply not using it.
.sh 4 "tls_srv_features and tls_clt_features"
.pp
The
.i tls_clt_features
-ruleset is called when sendmail connects to another MTA
+ruleset is called right before sendmail issues the
+.i STARTTLS
+command to another MTA
and the
.i tls_srv_features
-ruleset is called when a client connects to
+ruleset is called when a client sends the
+.i STARTTLS
+command to
.i sendmail .
The arguments for the rulesets are the host name and IP address
of the other side separated by
.b $|
(which is a metacharacter).
They should return a list of
.i key=value
pairs separated by semicolons;
the list can be empty if no options should be applied to the connection.
Available keys are and their allowed values are:
.nr ii 0.2i
.ip Options
A comma separated list of SSL related options.
See
.i ServerSSLOptions
and
.i ClientSSLOptions
for details, as well as
.i SSL_set_options (3)
and note this warning:
Options already set before are not cleared!
.ip CipherList
Specify cipher list for STARTTLS (does not apply to TLSv1.3),
see
.i ciphers (1)
for possible values.
This overrides the global
.i CipherList
for the session.
.ip CertFile
File containing a certificate.
.ip KeyFile
File containing the private key for the certificate.
.ip Flags
Currently the only valid flags are
.br
.i R
to require a CRL for each encountered certificate during verification
(by default a missing CRL is ignored),
.br
.i c
and
.i C
which basically clears/sets the option
.i TLSFallbacktoClear
for just this session, respectively,
.br
.i d
to turn off DANE which is obviously only valid for
.i tls_clt_features
and requires DANE to be compiled in.
This might be needed in case of a misconfiguration,
e.g.,
specifying invalid TLSA RRs.
.br
.lp
.lp
Example:
.(b
.ta 1.5i
Stls_srv_features
R$* $| 10.$+ $: cipherlist=HIGH
.)b
.lp
Notes:
.pp
Errors in these features (e.g., unknown keys or invalid values)
are logged
and the current session is aborted to avoid using STARTTLS
with features that should have been changed.
.pp
The keys are case-insensitive.
.pp
Both
.i CertFile
and
.i KeyFile
must be specified together;
specifying only one is an error.
.sh 4 "authinfo"
.pp
The
.i authinfo
ruleset is called when sendmail tries to authenticate to another MTA.
It should return
.b $#
followed by a list of tokens that are used for SMTP AUTH.
If the return value starts with anything else it is silently ignored.
Each token is a tagged string of the form:
"TDstring"
(including the quotes), where
.(b
.ta 9n
T Tag which describes the item
D Delimiter: ':' simple text follows
'=' string is base64 encoded
string Value of the item
.)b
Valid values for the tag are:
.(b
.ta 9n
U user (authorization) id
I authentication id
P password
R realm
M list of mechanisms delimited by spaces
.)b
If this ruleset is defined, the option
.b DefaultAuthInfo
is ignored (even if the ruleset does not return a ``useful'' result).
.sh 4 "queuegroup"
.pp
The
.i queuegroup
ruleset is used to map a recipient address to a queue group name.
The input for the ruleset is
the recipient address
(i.e., the address part of the resolved triple)
The ruleset should return
.b $#
followed by the name of a queue group.
If the return value starts with anything else it is silently ignored.
See the section about ``Queue Groups and Queue Directories''
for further information.
.sh 4 "greet_pause"
.pp
The
.i greet_pause
ruleset is used to specify the amount of time to pause before sending the
initial SMTP 220 greeting.
If any traffic is received during that pause, an SMTP 554 rejection
response is given instead of the 220 greeting and all SMTP commands are
rejected during that connection.
This helps protect sites from open proxies and SMTP slammers.
The ruleset should return
.b $#
followed by the number of milliseconds (thousandths of a second) to
pause.
If the return value starts with anything else or is not a number,
it is silently ignored.
Note: this ruleset is not invoked (and hence the feature is disabled)
when smtps (SMTP over SSL) is used, i.e.,
the
.i s
modifier is set for the daemon via
.b DaemonPortOptions ,
because in this case the SSL handshake is performed before
the greeting is sent.
.sh 3 "IPC mailers"
.pp
Some special processing occurs
if the ruleset zero resolves to an IPC mailer
(that is, a mailer that has
.q [IPC]
listed as the Path in the
.b M
configuration line.
The host name passed after
.q $@
has MX expansion performed if not delivering via a named socket;
this looks the name up in DNS to find alternate delivery sites.
.pp
The host name can also be provided as a dotted quad
or an IPv6 address in square brackets;
for example:
.(b
[128.32.149.78]
.)b
or
.(b
[IPv6:2002:c0a8:51d2::23f4]
.)b
This causes direct conversion of the numeric value
to an IP host address.
.pp
The host name passed in after the
.q $@
may also be a colon or comma separated list of hosts.
Each is separately MX expanded and the results are concatenated
to make (essentially) one long MX list.
Hosts separated by a comma have the same MX preference,
and for each colon separated host the MX preference is increased.
The intent here is to create
.q fake
MX records that are not published in DNS
for private internal networks.
.pp
As a final special case, the host name can be passed in
as a text string
in square brackets:
.(b
[ucbvax.berkeley.edu]
.)b
This form avoids the MX mapping.
.b N.B.:
.i
This is intended only for situations where you have a network firewall
or other host that will do special processing for all your mail,
so that your MX record points to a gateway machine;
this machine could then do direct delivery to machines
within your local domain.
Use of this feature directly violates RFC 1123 section 5.3.5:
it should not be used lightly.
.r
.sh 2 "D \*- Define Macro"
.pp
Macros are named with a single character
or with a word in {braces}.
The names ``x'' and ``{x}'' denote the same macro
for every single character ``x''.
Single character names may be selected from the entire ASCII set,
but user-defined macros
should be selected from the set of upper case letters only.
Lower case letters
and special symbols
are used internally.
Long names beginning with a lower case letter or a punctuation character
are reserved for use by sendmail,
so user-defined long macro names should begin with an upper case letter.
.pp
The syntax for macro definitions is:
.(b F
.b D \c
.i x\|val
.)b
where
.i x
is the name of the macro
(which may be a single character
or a word in braces)
and
.i val
is the value it should have.
There should be no spaces given
that do not actually belong in the macro value.
.pp
Macros are interpolated
using the construct
.b $ \c
.i x ,
where
.i x
is the name of the macro to be interpolated.
This interpolation is done when the configuration file is read,
except in
.b M
lines.
The special construct
.b $& \c
.i x
can be used in
.b R
lines to get deferred interpolation.
.pp
Conditionals can be specified using the syntax:
.(b
$?x text1 $| text2 $.
.)b
This interpolates
.i text1
if the macro
.b $x
is set and non-null,
and
.i text2
otherwise.
The
.q else
(\c
.b $| )
clause may be omitted.
.pp
The following macros are defined and/or used internally by
.i sendmail
for interpolation into argv's for mailers
or for other contexts.
The ones marked \(dg are information passed into sendmail\**,
.(f
\**As of version 8.6,
all of these macros have reasonable defaults.
Previous versions required that they be defined.
.)f
the ones marked \(dd are information passed both in and out of sendmail,
and the unmarked macros are passed out of sendmail
but are not otherwise used internally.
These macros are:
.nr ii 5n
.ip $a
The origination date in RFC 822 format.
This is extracted from the Date: line.
.ip $b
The current date in RFC 822 format.
.ip $c
The hop count.
This is a count of the number of Received: lines
plus the value of the
.b \-h
command line flag.
.ip $d
The current date in UNIX (ctime) format.
.ip $e\(dg
(Obsolete; use SmtpGreetingMessage option instead.)
The SMTP entry message.
This is printed out when SMTP starts up.
The first word must be the
.b $j
macro as specified by RFC 821.
Defaults to
.q "$j Sendmail $v ready at $b" .
Commonly redefined to include the configuration version number, e.g.,
.q "$j Sendmail $v/$Z ready at $b"
.ip $f
The envelope sender (from) address.
.ip $g
The sender address relative to the recipient.
For example, if
.b $f
is
.q foo ,
.b $g
will be
.q host!foo ,
.q foo@host.domain ,
or whatever is appropriate for the receiving mailer.
.ip $h
The recipient host.
This is set in ruleset 0 from the $@ field of a parsed address.
.ip $i
The queue id,
e.g.,
.q f344MXxp018717 .
.ip $j\(dd
The \*(lqofficial\*(rq domain name for this site.
This is fully qualified if the full qualification can be found.
It
.i must
be redefined to be the fully qualified domain name
if your system is not configured so that information can find
it automatically.
.ip $k
The UUCP node name (from the uname system call).
.ip $l\(dg
(Obsolete; use UnixFromLine option instead.)
The format of the UNIX from line.
Unless you have changed the UNIX mailbox format,
you should not change the default,
which is
.q "From $g $d" .
.ip $m
The domain part of the \fIgethostname\fP return value.
Under normal circumstances,
.b $j
is equivalent to
.b $w.$m .
.ip $n\(dg
The name of the daemon (for error messages).
Defaults to
.q MAILER-DAEMON .
.ip $o\(dg
(Obsolete: use OperatorChars option instead.)
The set of \*(lqoperators\*(rq in addresses.
A list of characters
which will be considered tokens
and which will separate tokens
when doing parsing.
For example, if
.q @
were in the
.b $o
macro, then the input
.q a@b
would be scanned as three tokens:
.q a,
.q @,
and
.q b.
Defaults to
.q ".:@[]" ,
which is the minimum set necessary to do RFC 822 parsing;
a richer set of operators is
.q ".:%@!/[]" ,
which adds support for UUCP, the %-hack, and X.400 addresses.
.ip $p
Sendmail's process id.
.ip $q\(dg
Default format of sender address.
The
.b $q
macro specifies how an address should appear in a message
when it is defaulted.
Defaults to
.q "<$g>" .
It is commonly redefined to be
.q "$?x$x <$g>$|$g$."
or
.q "$g$?x ($x)$." ,
corresponding to the following two formats:
.(b
Eric Allman <eric@CS.Berkeley.EDU>
eric@CS.Berkeley.EDU (Eric Allman)
.)b
.i Sendmail
properly quotes names that have special characters
if the first form is used.
.ip $r
Protocol used to receive the message.
Set from the
.b \-p
command line flag or by the SMTP server code.
.ip $s
Sender's host name.
Set from the
.b \-p
command line flag or by the SMTP server code
(in which case it is set to the EHLO/HELO parameter).
.ip $t
A numeric representation of the current time in the format YYYYMMDDHHmm
(4 digit year 1900-9999, 2 digit month 01-12, 2 digit day 01-31,
2 digit hours 00-23, 2 digit minutes 00-59).
.ip $u
The recipient user.
.ip $v
The version number of the
.i sendmail
binary.
.ip $w\(dd
The hostname of this site.
This is the root name of this host (but see below for caveats).
.ip $x
The full name of the sender.
.ip $z
The home directory of the recipient.
.ip $_
The validated sender address.
See also
.b ${client_resolve} .
.ip ${addr_type}
The type of the address which is currently being rewritten.
This macro contains up to three characters, the first
is either `e' or `h' for envelope/header address,
the second is a space,
and the third is either `s' or `r' for sender/recipient address.
.ip ${alg_bits}
The maximum keylength (in bits) of the symmetric encryption algorithm
used for a TLS connection.
This may be less than the effective keylength,
which is stored in
.b ${cipher_bits} ,
for ``export controlled'' algorithms.
.ip ${auth_authen}
The client's authentication credentials as determined by authentication
(only set if successful).
The format depends on the mechanism used, it might be just `user',
or `user@realm', or something similar (SMTP AUTH only).
.ip ${auth_author}
The authorization identity, i.e. the AUTH= parameter of the
.sm "SMTP MAIL"
command if supplied.
.ip ${auth_type}
The mechanism used for SMTP authentication
(only set if successful).
.ip ${auth_ssf}
The keylength (in bits) of the symmetric encryption algorithm
used for the security layer of a SASL mechanism.
.ip ${bodytype}
The message body type
(7BIT or 8BITMIME),
as determined from the envelope.
.ip ${cert_fp}
The fingerprint of the presented certificate (STARTTLS only).
Note: this macro is only defined if the option
.b CertFingerprintAlgorithm
is set,
in which case the specified fingerprint algorithm is used.
The valid algorithms depend on the OpenSSL version,
but usually md5, sha1, and sha256 are available.
See
.(b
openssl dgst -h
.)b
for a list.
.ip ${cert_issuer}
The DN (distinguished name) of the CA (certificate authority)
that signed the presented certificate (the cert issuer)
(STARTTLS only).
.ip ${cert_md5}
The MD5 hash of the presented certificate (STARTTLS only).
Note: this macro is only defined if the option
.b CertFingerprintAlgorithm
is not set.
.ip ${cert_subject}
The DN of the presented certificate (called the cert subject)
(STARTTLS only).
.ip ${cipher}
The cipher suite used for the connection, e.g., EDH-DSS-DES-CBC3-SHA,
EDH-RSA-DES-CBC-SHA, DES-CBC-MD5, DES-CBC3-SHA
(STARTTLS only).
.ip ${cipher_bits}
The effective keylength (in bits) of the symmetric encryption algorithm
used for a TLS connection.
.ip ${client_addr}
The IP address of the SMTP client.
IPv6 addresses are tagged with "IPv6:" before the address.
Defined in the SMTP server only.
.ip ${client_connections}
The number of open connections in the SMTP server for the client IP address.
.ip ${client_flags}
The flags specified by the
Modifier= part of
.b ClientPortOptions
where flags are separated from each other by spaces
and upper case flags are doubled.
That is,
Modifier=hA
will be represented as
"h AA" in
.b ${client_flags} ,
which is required for testing the flags in rulesets.
.ip ${client_name}
The host name of the SMTP client.
This may be the client's bracketed IP address
in the form [ nnn.nnn.nnn.nnn ] for IPv4
and [ IPv6:nnnn:...:nnnn ] for IPv6
if the client's
IP address is not resolvable, or if it is resolvable
but the IP address of the resolved hostname
doesn't match the original IP address.
Defined in the SMTP server only.
See also
.b ${client_resolve} .
.ip ${client_port}
The port number of the SMTP client.
Defined in the SMTP server only.
.ip ${client_ptr}
The result of the PTR lookup for the client IP address.
Note: this is the same as
.b ${client_name}
if and only if
.b ${client_resolve}
is OK.
Defined in the SMTP server only.
.ip ${client_rate}
The number of incoming connections for the client IP address
over the time interval specified by ConnectionRateWindowSize.
.ip ${client_resolve}

Defined in the SMTP server only.
.i sendmail
performs a hostname lookup on the IP address of the connecting client.
Next the IP addresses of that hostname are looked up.
If the client IP address does not appear in that list,
then the hostname is maybe forged.
This is reflected as the value FORGED for
.b ${client_resolve}
and it also shows up in
.b $_
as "(may be forged)".
.ip ${cn_issuer}
The CN (common name) of the CA that signed the presented certificate
(STARTTLS only).
Note: if the CN cannot be extracted properly it will be replaced by
one of these strings based on the encountered error:
.(b
.ta 25n
BadCertificateContainsNUL CN contains a NUL character
BadCertificateTooLong CN is too long
BadCertificateUnknown CN could not be extracted
.)b
In the last case, some other (unspecific) error occurred.
.ip ${cn_subject}
The CN (common name) of the presented certificate
(STARTTLS only).
See
.b ${cn_issuer}
for possible replacements.
.ip ${currHeader}
Header value as quoted string
(possibly truncated to
.b MAXNAME ).
This macro is only available in header check rulesets.
.ip ${daemon_addr}
The IP address the daemon is listening on for connections.
.ip ${daemon_family}
The network family
if the daemon is accepting network connections.
Possible values include
.q inet ,
.q inet6 ,
.q iso ,
.q ns ,
.q x.25
.ip ${daemon_flags}
The flags for the daemon as specified by the
Modifier= part of
.b DaemonPortOptions
whereby the flags are separated from each other by spaces,
and upper case flags are doubled.
That is,
Modifier=Ea
will be represented as
"EE a" in
.b ${daemon_flags} ,
which is required for testing the flags in rulesets.
.ip ${daemon_info}
Some information about a daemon as a text string.
For example,
.q SMTP+queueing@00:30:00 .
.ip ${daemon_name}
The name of the daemon from
.b DaemonPortOptions
Name= suboption.
If this suboption is not set,
"Daemon#",
where # is the daemon number,
is used.
.ip ${daemon_port}
The port the daemon is accepting connection on.
Unless
.b DaemonPortOptions
is set, this will most likely be
.q 25 .
.ip ${deliveryMode}
The current delivery mode sendmail is using.
It is initially set to the value of the
.b DeliveryMode
option.
+.ip ${dsn_envid}
+The envelope id parameter (ENVID=) passed to sendmail as part of the envelope.
+.ip ${dsn_notify}
+Value of DSN NOTIFY= parameter
+(never, success, failure, delay, or empty string).
+.ip ${dsn_ret}
+Value of DSN RET= parameter (hdrs, full, or empty string).
.ip ${envid}
The envelope id parameter (ENVID=) passed to sendmail as part of the envelope.
.ip ${hdrlen}
The length of the header value which is stored in
${currHeader} (before possible truncation).
If this value is greater than or equal to
.b MAXNAME
the header has been truncated.
.ip ${hdr_name}
The name of the header field for which the current header
check ruleset has been called.
This is useful for a default header check ruleset to get
the name of the header;
the macro is only available in header check rulesets.
.ip ${if_addr}
The IP address of the interface of an incoming connection
unless it is in the loopback net.
IPv6 addresses are tagged with "IPv6:" before the address.
.ip ${if_addr_out}
The IP address of the interface of an outgoing connection
unless it is in the loopback net.
IPv6 addresses are tagged with "IPv6:" before the address.
.ip ${if_family}
The IP family of the interface of an incoming connection
unless it is in the loopback net.
.ip ${if_family_out}
The IP family of the interface of an outgoing connection
unless it is in the loopback net.
.ip ${if_name}
The hostname associated with the interface of an incoming connection.
This macro can be used for
SmtpGreetingMessage and HReceived for virtual hosting.
For example:
.(b
O SmtpGreetingMessage=$?{if_name}${if_name}$|$j$. MTA
.)b
.ip ${if_name_out}
The name of the interface of an outgoing connection.
.ip ${load_avg}
The current load average.
.ip ${mail_addr}
The address part of the resolved triple of the address given for the
.sm "SMTP MAIL"
command.
Defined in the SMTP server only.
.ip ${mail_host}
The host from the resolved triple of the address given for the
.sm "SMTP MAIL"
command.
Defined in the SMTP server only.
.ip ${mail_mailer}
The mailer from the resolved triple of the address given for the
.sm "SMTP MAIL"
command.
Defined in the SMTP server only.
.ip ${msg_id}
The value of the Message-Id: header.
.ip ${msg_size}
The value of the SIZE= parameter,
i.e., usually the size of the message (in an ESMTP dialogue),
before the message has been collected, thereafter
the message size as computed by
.i sendmail
(and can be used in check_compat).
.ip ${nbadrcpts}
The number of bad recipients for a single message.
.ip ${nrcpts}
The number of validated recipients for a single message.
Note: since recipient validation happens after
.i check_rcpt
has been called, the value in this ruleset
is one less than what might be expected.
.ip ${ntries}
The number of delivery attempts.
.ip ${opMode}
The current operation mode (from the
.b \-b
flag).
.ip ${quarantine}
The quarantine reason for the envelope,
if it is quarantined.
.ip ${queue_interval}
The queue run interval given by the
.b \-q
flag.
For example,
.b \-q30m
would set
.b ${queue_interval}
to
.q 00:30:00 .
.ip ${rcpt_addr}
The address part of the resolved triple of the address given for the
.sm "SMTP RCPT"
command.
Defined in the SMTP server only after a RCPT command.

.sm "SMTP RCPT"
command.
Defined in the SMTP server only after a RCPT command.
.ip ${rcpt_mailer}
The mailer from the resolved triple of the address given for the
.sm "SMTP RCPT"
command.
Defined in the SMTP server only after a RCPT command.
.ip ${server_addr}
The address of the server of the current outgoing SMTP connection.
For LMTP delivery the macro is set to the name of the mailer.
+(only if sendmail is compiled with STARTTLS or SASL.)
.ip ${server_name}
The name of the server of the current outgoing SMTP or LMTP connection.
+(only if sendmail is compiled with STARTTLS or SASL.)
.ip ${time}
The output of the
.i time (3)
function, i.e., the number of seconds since 0 hours, 0 minutes,
0 seconds, January 1, 1970, Coordinated Universal Time (UTC).
.ip ${tls_version}
The TLS/SSL version used for the connection, e.g., TLSv1.2, TLSv1;
defined after STARTTLS has been used.
.ip ${total_rate}
The total number of incoming connections over the time interval specified
by ConnectionRateWindowSize.
.ip ${verify}
The result of the verification of the presented cert;
only defined after STARTTLS has been used (or attempted).
Possible values are:
.(b
.ta 13n
+TRUSTED verification via DANE succeeded.
OK verification succeeded.
NO no cert presented.
NOT no cert requested.
FAIL cert presented but could not be verified,
e.g., the signing CA is missing.
NONE STARTTLS has not been performed.
CLEAR STARTTLS has been disabled internally for a clear text delivery attempt.
TEMP temporary error occurred.
PROTOCOL some protocol error occurred
at the ESMTP level (not TLS).
SOFTWARE STARTTLS handshake failed,
which is a fatal error for this session,
the e-mail will be queued.
.)b
.pp
There are three types of dates that can be used.
The
.b $a
and
.b $b
macros are in RFC 822 format;
.b $a
is the time as extracted from the
.q Date:
line of the message
(if there was one),
and
.b $b
is the current date and time
(used for postmarks).
If no
.q Date:
line is found in the incoming message,
.b $a
is set to the current time also.
The
.b $d
macro is equivalent to the
.b $b
macro in UNIX
(ctime)
format.
.pp
The macros
.b $w ,
.b $j ,
and
.b $m
are set to the identity of this host.
.i Sendmail
tries to find the fully qualified name of the host
if at all possible;
it does this by calling
.i gethostname (2)
to get the current hostname
and then passing that to
.i gethostbyname (3)
which is supposed to return the canonical version of that host name.\**
.(f
\**For example, on some systems
.i gethostname
might return
.q foo
which would be mapped to
.q foo.bar.com
by
.i gethostbyname .
.)f
Assuming this is successful,
.b $j
is set to the fully qualified name
and
.b $m
is set to the domain part of the name
(everything after the first dot).
The
.b $w
macro is set to the first word
(everything before the first dot)
if you have a level 5 or higher configuration file;
otherwise, it is set to the same value as
.b $j .
If the canonification is not successful,
it is imperative that the config file set
.b $j
to the fully qualified domain name\**.
.(f
\**Older versions of sendmail didn't pre-define
.b $j
at all, so up until 8.6,
config files
.i always
had to define
.b $j .
.)f
.pp
The
.b $f
macro is the id of the sender
as originally determined;
when mailing to a specific host
the
.b $g
macro is set to the address of the sender
.ul
relative to the recipient.
For example,
if I send to
.q bollard@matisse.CS.Berkeley.EDU
from the machine
.q vangogh.CS.Berkeley.EDU
the
.b $f
macro will be
.q eric
and the
.b $g
macro will be
.q eric@vangogh.CS.Berkeley.EDU.
.pp
The
.b $x
macro is set to the full name of the sender.
This can be determined in several ways.
It can be passed as flag to
.i sendmail .
It can be defined in the
.sm NAME
environment variable.
The third choice is the value of the
.q Full-Name:
line in the header if it exists,
and the fourth choice is the comment field
of a
.q From:
line.
If all of these fail,
and if the message is being originated locally,
the full name is looked up in the
.i /etc/passwd
file.
.pp
When sending,
the
.b $h ,
.b $u ,
and
.b $z
macros get set to the host, user, and home directory
(if local)
of the recipient.
The first two are set from the
.b $@
and
.b $:
part of the rewriting rules, respectively.
.pp
The
.b $p
and
.b $t
macros are used to create unique strings
(e.g., for the
.q Message-Id:
field).
The
.b $i
macro is set to the queue id on this host;
if put into the timestamp line
it can be extremely useful for tracking messages.
The
.b $v
macro is set to be the version number of
.i sendmail ;
this is normally put in timestamps
and has been proven extremely useful for debugging.
.pp
The
.b $c
field is set to the
.q "hop count,"
i.e., the number of times this message has been processed.
This can be determined
by the
.b \-h
flag on the command line
or by counting the timestamps in the message.
.pp
The
.b $r
and
.b $s
fields are set to the protocol used to communicate with
.i sendmail
and the sending hostname.
They can be set together using the
.b \-p
command line flag or separately using the
.b \-M
or
.b \-oM
flags.
.pp
The
.b $_
is set to a validated sender host name.
If the sender is running an RFC 1413 compliant IDENT server
and the receiver has the IDENT protocol turned on,
it will include the user name on that host.
.pp
The
.b ${client_name} ,
.b ${client_addr} ,
and
.b ${client_port}
macros
are set to the name, address, and port number of the SMTP client
who is invoking
.i sendmail
as a server.
These can be used in the
.i check_*
rulesets (using the
.b $&
deferred evaluation form, of course!).
.sh 2 "C and F \*- Define Classes"
.pp
Classes of phrases may be defined
to match on the left hand side of rewriting rules,
where a
.q phrase
is a sequence of characters that does not contain space characters.
For example
a class of all local names for this site
might be created
so that attempts to send to oneself
can be eliminated.
These can either be defined directly in the configuration file
or read in from another file.
Classes are named as a single letter or a word in {braces}.
Class names beginning with lower case letters
and special characters are reserved for system use.
Classes defined in config files may be given names
from the set of upper case letters for short names
or beginning with an upper case letter for long names.
.pp
The syntax is:
.(b F
.b C \c
.i c\|phrase1
.i phrase2...
.br
.b F \c
.i c\|file
.br
.b F \c
.i c\||program
.br
.b F \c
.i c\|[mapkey]@mapclass:mapspec
.)b
The first form defines the class
.i c
to match any of the named words.
If
.i phrase1
or
.i phrase2
is another class,
e.g.,
.i $=S ,
the contents of class
.i S
are added to class
.i c .
It is permissible to split them among multiple lines;
for example, the two forms:
.(b
CHmonet ucbmonet
.)b
and
.(b
CHmonet
CHucbmonet
.)b
are equivalent.
The ``F'' forms
read the elements of the class
.i c
from the named
.i file ,
.i program ,
or
.i "map specification" .
Each element should be listed on a separate line.
To specify an optional file, use ``\-o'' between the class
name and the file name, e.g.,
.(b
Fc \-o /path/to/file
.)b
If the file can't be used,
.i sendmail
will not complain but silently ignore it.
The map form should be an optional map key, an at sign,
and a map class followed by the specification for that map.
Examples include:
.(b
F{VirtHosts}@ldap:\-k (&(objectClass=virtHosts)(host=*)) \-v host
F{MyClass}foo@hash:/etc/mail/classes
.)b
will fill the class
.b $={VirtHosts}
from an LDAP map lookup and
.b $={MyClass}
from a hash database map lookup of the
.b foo .
There is also a built-in schema that can be accessed by only specifying:
.(b
F{\c
.i ClassName }@LDAP
.)b
This will tell sendmail to use the default schema:
.(b
\-k (&(objectClass=sendmailMTAClass)
(sendmailMTAClassName=\c
.i ClassName )
(|(sendmailMTACluster=${sendmailMTACluster})
(sendmailMTAHost=$j)))
\-v sendmailMTAClassValue
.)b
Note that the lookup is only done when sendmail is initially started.
.pp
Elements of classes can be accessed in rules using
.b $=
or
.b $~ .
The
.b $~
(match entries not in class)
only matches a single word;
multi-word entries in the class are ignored in this context.
.pp
Some classes have internal meaning to
.i sendmail :
.nr ii 0.5i
.\".ip $=b
.\"A set of Content-Types that will not have the newline character
.\"translated to CR-LF before encoding into base64 MIME.
.\"The class can have major times
.\"(e.g.,
.\".q image )
.\"or full types
.\"(such as
.\".q application/octet-stream ).
.\"The class is initialized with
.\".q application/octet-stream ,
.\".q image ,
.\".q audio ,
.\"and
.\".q video .
.ip $=e
contains the Content-Transfer-Encodings that can be 8\(->7 bit encoded.
It is predefined to contain
.q 7bit ,
.q 8bit ,
and
.q binary .
.ip $=k
set to be the same as
.b $k ,
that is, the UUCP node name.
.ip $=m
set to the set of domains by which this host is known,
initially just
.b $m .
.ip $=n
can be set to the set of MIME body types
that can never be eight to seven bit encoded.
It defaults to
.q multipart/signed .
Message types
.q message/*
and
.q multipart/*
are never encoded directly.
Multipart messages are always handled recursively.
The handling of message/* messages
are controlled by class
.b $=s .
.ip $=q
A set of Content-Types that will never be encoded as base64
(if they have to be encoded, they will be encoded as quoted-printable).
It can have primary types
(e.g.,
.q text )
or full types
(such as
.q text/plain ).
.ip $=s
contains the set of subtypes of message that can be treated recursively.
By default it contains only
.q rfc822 .
Other
.q message/*
types cannot be 8\(->7 bit encoded.
If a message containing eight bit data is sent to a seven bit host,
and that message cannot be encoded into seven bits,
it will be stripped to 7 bits.
.ip $=t
set to the set of trusted users by the
.b T
configuration line.
If you want to read trusted users from a file, use
.b Ft \c
.i /file/name .
.ip $=w
set to be the set of all names
this host is known by.
This can be used to match local hostnames.
.ip $={persistentMacros}
set to the macros that should be saved across queue runs.
Care should be taken when adding macro names to this class.
.pp
.i Sendmail
can be compiled to allow a
.i scanf (3)
string on the
.b F
line.
This lets you do simplistic parsing of text files.
For example, to read all the user names in your system
.i /etc/passwd
file into a class, use
.(b
FL/etc/passwd %[^:]
.)b
which reads every line up to the first colon.
.sh 2 "M \*- Define Mailer"
.pp
Programs and interfaces to mailers
are defined in this line.
The format is:
.(b F
.b M \c
.i name ,
{\c
.i field =\c
.i value \|}*
.)b
where
.i name
is the name of the mailer
(used internally only)
and the
.q field=name
pairs define attributes of the mailer.
Fields are:
.(b
.ta 1i
Path The pathname of the mailer
Flags Special flags for this mailer
Sender Rewriting set(s) for sender addresses
Recipient Rewriting set(s) for recipient addresses
recipients Maximum number of recipients per connection
Argv An argument vector to pass to this mailer
Eol The end-of-line string for this mailer
Maxsize The maximum message length to this mailer
maxmessages The maximum message deliveries per connection
Linelimit The maximum line length in the message body
Directory The working directory for the mailer
Userid The default user and group id to run as
Nice The nice(2) increment for the mailer
Charset The default character set for 8-bit characters
Type Type information for DSN diagnostics
Wait The maximum time to wait for the mailer
Queuegroup The default queue group for the mailer
/ The root directory for the mailer
.)b
Only the first character of the field name is checked
(it's case-sensitive).
.pp
The following flags may be set in the mailer description.
Any other flags may be used freely
to conditionally assign headers to messages
destined for particular mailers.
Flags marked with \(dg
are not interpreted by the
.i sendmail
binary;
these are the conventionally used to correlate to the flags portion
of the
.b H
line.
Flags marked with \(dd
apply to the mailers for the sender address
rather than the usual recipient mailers.
.nr ii 4n
.ip a
Run Extended SMTP (ESMTP) protocol (defined in RFCs 1869, 1652, and 1870).
This flag defaults on if the SMTP greeting message includes the word
.q ESMTP .
.ip A
Look up the user (address) part of the resolved mailer triple,
in the alias database.
Normally this is only set for local mailers.
.ip b
Force a blank line on the end of a message.
This is intended to work around some stupid versions of
/bin/mail
that require a blank line, but do not provide it themselves.
It would not normally be used on network mail.
.ip B
Strip leading backslashes (\e) off of the address;
this is a subset of the functionality of the
.b s
flag.
.ip c
Do not include comments in addresses.
This should only be used if you have to work around
a remote mailer that gets confused by comments.
This strips addresses of the form
.q "Phrase <address>"
or
.q "address (Comment)"
down to just
.q address .
.ip C\(dd
If mail is
.i received
from a mailer with this flag set,
any addresses in the header that do not have an at sign
(\c
.q @ )
after being rewritten by ruleset three
will have the
.q @domain
clause from the sender envelope address
tacked on.
This allows mail with headers of the form:
.(b
From: usera@hosta
To: userb@hostb, userc
.)b
to be rewritten as:
.(b
From: usera@hosta
To: userb@hostb, userc@hosta
.)b
automatically.
However, it doesn't really work reliably.
.ip d
Do not include angle brackets around route-address syntax addresses.
This is useful on mailers that are going to pass addresses to a shell
that might interpret angle brackets as I/O redirection.
However, it does not protect against other shell metacharacters.
Therefore, passing addresses to a shell should not be considered secure.
.ip D\(dg
This mailer wants a
.q Date:
header line.
.ip e
This mailer is expensive to connect to,
so try to avoid connecting normally;
any necessary connection will occur during a queue run.
See also option
.b HoldExpensive .
.ip E
Escape lines beginning with
.q From\0
in the message with a `>' sign.
.ip f
The mailer wants a
.b \-f
.i from
flag,
but only if this is a network forward operation
(i.e.,
the mailer will give an error
if the executing user
does not have special permissions).
.ip F\(dg
This mailer wants a
.q From:
header line.
.ip g
Normally,
.i sendmail
sends internally generated email (e.g., error messages)
using the null return address
as required by RFC 1123.
However, some mailers don't accept a null return address.
If necessary,
you can set the
.b g
flag to prevent
.i sendmail
from obeying the standards;
error messages will be sent as from the MAILER-DAEMON
(actually, the value of the
.b $n
macro).
.ip h
Upper case should be preserved in host names
(the $@ portion of the mailer triplet resolved from ruleset 0)
for this mailer.
.ip i
Do User Database rewriting on envelope sender address.
.ip I
This flag is deprecated
and will be removed from a future version.
This mailer will be speaking SMTP
to another
.i sendmail
\*-
as such it can use special protocol features.
This flag should not be used except for debugging purposes
because it uses
.b VERB
as SMTP command.
.ip j
Do User Database rewriting on recipients as well as senders.
.ip k
Normally when
.i sendmail
connects to a host via SMTP,
it checks to make sure that this isn't accidentally the same host name
as might happen if
.i sendmail
is misconfigured or if a long-haul network interface is set in loopback mode.
This flag disables the loopback check.
It should only be used under very unusual circumstances.
.ip K
Currently unimplemented.
Reserved for chunking.
.ip l
This mailer is local
(i.e.,
final delivery will be performed).
.ip L
Limit the line lengths as specified in RFC 821.
This deprecated option should be replaced by the
.b L=
mail declaration.
For historic reasons, the
.b L
flag also sets the
.b 7
flag.
.ip m
This mailer can send to multiple users
on the same host
in one transaction.
When a
.b $u
macro occurs in the
.i argv
part of the mailer definition,
that field will be repeated as necessary
for all qualifying users.
Removing this flag can defeat duplicate suppression on a remote site
as each recipient is sent in a separate transaction.
.ip M\(dg
This mailer wants a
.q Message-Id:
header line.
.ip n
Do not insert a UNIX-style
.q From
line on the front of the message.
.ip o
Always run as the owner of the recipient mailbox.
Normally
.i sendmail
runs as the sender for locally generated mail
or as
.q daemon
(actually, the user specified in the
.b u
option)
when delivering network mail.
The normal behavior is required by most local mailers,
which will not allow the envelope sender address
to be set unless the mailer is running as daemon.
This flag is ignored if the
.b S
flag is set.
.ip p
Use the route-addr style reverse-path in the SMTP
-.q "MAIL FROM:"
+.sm "SMTP MAIL"
command
rather than just the return address;
although this is required in RFC 821 section 3.1,
many hosts do not process reverse-paths properly.
Reverse-paths are officially discouraged by RFC 1123.
.ip P\(dg
This mailer wants a
.q Return-Path:
line.
.ip q
When an address that resolves to this mailer is verified
(SMTP VRFY command),
generate 250 responses instead of 252 responses.
This will imply that the address is local.
.ip r
Same as
.b f ,
but sends a
.b \-r
flag.
.ip R
Open SMTP connections from a
.q secure
port.
Secure ports aren't
(secure, that is)
except on UNIX machines,
so it is unclear that this adds anything.
.i sendmail
must be running as root to be able to use this flag.
.ip s
Strip quote characters (" and \e) off of the address
before calling the mailer.
.ip S
Don't reset the userid
before calling the mailer.
This would be used in a secure environment
where
.i sendmail
ran as root.
This could be used to avoid forged addresses.
If the
.b U=
field is also specified,
this flag causes the effective user id to be set to that user.
.ip u
Upper case should be preserved in user names for this mailer. Standards
require preservation of case in the local part of addresses, except for
those address for which your system accepts responsibility.
RFC 2142 provides a long list of addresses which should be case
insensitive.
If you use this flag, you may be violating RFC 2142.
Note that postmaster is always treated as a case insensitive address
regardless of this flag.
.ip U
This mailer wants UUCP-style
.q From
lines with the ugly
.q "remote from <host>"
on the end.
.ip w
The user must have a valid account on this machine,
i.e.,
.i getpwnam
must succeed.
If not, the mail is bounced.
See also the
-.b MailBoxDatabase
+.b MailboxDatabase
option.
This is required to get
.q \&.forward
capability.
.ip W
Ignore long term host status information (see Section
"Persistent Host Status Information").
.ip x\(dg
This mailer wants a
.q Full-Name:
header line.
.ip X
This mailer wants to use the hidden dot algorithm as specified in RFC 821;
basically, any line beginning with a dot will have an extra dot prepended
(to be stripped at the other end).
This insures that lines in the message containing a dot
will not terminate the message prematurely.
.ip z
Run Local Mail Transfer Protocol (LMTP)
between
.i sendmail
and the local mailer.
This is a variant on SMTP
defined in RFC 2033
that is specifically designed for delivery to a local mailbox.
.ip Z
Apply DialDelay (if set) to this mailer.
.ip 0
Don't look up MX records for hosts sent via SMTP/LMTP.
Do not apply
.b FallbackMXhost
either.
.ip 1
Don't send null characters ('\\0') to this mailer.
.ip 2
Don't use ESMTP even if offered; this is useful for broken
systems that offer ESMTP but fail on EHLO (without recovering
when HELO is tried next).
.ip 3
Extend the list of characters converted to =XX notation
when converting to Quoted-Printable
to include those that don't map cleanly between ASCII and EBCDIC.
Useful if you have IBM mainframes on site.
.ip 5
If no aliases are found for this address,
pass the address through ruleset 5 for possible alternate resolution.
This is intended to forward the mail to an alternate delivery spot.
.ip 6
Strip headers to seven bits.
.ip 7
Strip all output to seven bits.
This is the default if the
.b L
flag is set.
Note that clearing this option is not
sufficient to get full eight bit data passed through
.i sendmail .
If the
.b 7
option is set, this is essentially always set,
since the eighth bit was stripped on input.
Note that this option will only impact messages
that didn't have 8\(->7 bit MIME conversions performed.
.ip 8
If set,
it is acceptable to send eight bit data to this mailer;
the usual attempt to do 8\(->7 bit MIME conversions will be bypassed.
.ip 9
If set,
do
.i limited
7\(->8 bit MIME conversions.
These conversions are limited to text/plain data.
.ip :
Check addresses to see if they begin
.q :include: ;
if they do, convert them to the
.q *include*
mailer.
.ip |
Check addresses to see if they begin with a `|';
if they do, convert them to the
.q prog
mailer.
.ip /
Check addresses to see if they begin with a `/';
if they do, convert them to the
.q *file*
mailer.
.ip @
Look up addresses in the user database.
.ip %
Do not attempt delivery on initial receipt of a message
or on queue runs
unless the queued message is selected
using one of the -qI/-qR/-qS queue run modifiers
or an ETRN request.
.ip !
Disable an MH hack that drops an explicit
From: header
if it is the same as what sendmail would generate.
.pp
Configuration files prior to level 6
assume the `A', `w', `5', `:', `|', `/', and `@' options
on the mailer named
.q local .
.pp
The mailer with the special name
.q error
can be used to generate a user error.
The (optional) host field is an exit status to be returned,
and the user field is a message to be printed.
The exit status may be numeric or one of the values
USAGE, NOUSER, NOHOST, UNAVAILABLE, SOFTWARE, TEMPFAIL, PROTOCOL, or CONFIG
to return the corresponding EX_ exit code,
or an enhanced error code as described in RFC 1893,
.ul
Enhanced Mail System Status Codes.
For example, the entry:
.(b
$#error $@ NOHOST $: Host unknown in this domain
.)b
on the RHS of a rule
will cause the specified error to be generated
and the
.q "Host unknown"
exit status to be returned
if the LHS matches.
This mailer is only functional in rulesets 0, 5,
or one of the check_* rulesets.
The host field can also contain the special token
.b quarantine
which instructs sendmail to quarantine the current message.
.pp
The mailer with the special name
.q discard
causes any mail sent to it to be discarded
but otherwise treated as though it were successfully delivered.
This mailer cannot be used in ruleset 0,
only in the various address checking rulesets.
.pp
The mailer named
.q local
.i must
be defined in every configuration file.
This is used to deliver local mail,
and is treated specially in several ways.
Additionally, three other mailers named
.q prog ,
.q *file* ,
and
.q *include*
may be defined to tune the delivery of messages to programs,
files,
and :include: lists respectively.
They default to:
.(b
Mprog, P=/bin/sh, F=lsoDq9, T=DNS/RFC822/X-Unix, A=sh \-c $u
M*file*, P=[FILE], F=lsDFMPEouq9, T=DNS/RFC822/X-Unix, A=FILE $u
M*include*, P=/dev/null, F=su, A=INCLUDE $u
.)b
.pp
Builtin pathnames are [FILE] and [IPC], the former is used for
delivery to files, the latter for delivery via interprocess communication.
For mailers that use [IPC] as pathname the argument vector (A=)
must start with TCP or FILE for delivery via a TCP or a Unix domain socket.
If TCP is used, the second argument must be the name of the host
to contact.
Optionally a third argument can be used to specify a port,
the default is smtp (port 25).
If FILE is used, the second argument must be the name of
the Unix domain socket.
.pp
If the argument vector does not contain $u then
.i sendmail
will speak SMTP (or LMTP if the mailer flag z is specified) to the mailer.
.pp
If no Eol field is defined, then the default is "\\r\\n" for
SMTP mailers and "\\n" of others.
.pp
The Sender and Recipient rewriting sets
may either be a simple ruleset id
or may be two ids separated by a slash;
if so, the first rewriting set is applied to envelope
addresses
and the second is applied to headers.
Setting any value to zero disables corresponding mailer-specific rewriting.
.pp
The Directory
is actually a colon-separated path of directories to try.
For example, the definition
.q D=$z:/
first tries to execute in the recipient's home directory;
if that is not available,
it tries to execute in the root of the filesystem.
This is intended to be used only on the
.q prog
mailer,
since some shells (such as
.i csh )
refuse to execute if they cannot read the current directory.
Since the queue directory is not normally readable by unprivileged users
.i csh
scripts as recipients can fail.
.pp
The Userid
specifies the default user and group id to run as,
overriding the
.b DefaultUser
option (q.v.).
If the
.b S
mailer flag is also specified,
this user and group will be set as the
effective uid and gid for the process.
This may be given as
.i user:group
to set both the user and group id;
either may be an integer or a symbolic name to be looked up
in the
.i passwd
and
.i group
files respectively.
If only a symbolic user name is specified,
the group id in the
.i passwd
file for that user is used as the group id.
.pp
The Charset field
is used when converting a message to MIME;
this is the character set used in the
Content-Type: header.
If this is not set, the
-.b DefaultCharset
+.b DefaultCharSet
option is used,
and if that is not set, the value
.q unknown-8bit
is used.
.b WARNING:
this field applies to the sender's mailer,
not the recipient's mailer.
For example, if the envelope sender address
lists an address on the local network
and the recipient is on an external network,
the character set will be set from the Charset= field
for the local network mailer,
not that of the external network mailer.
.pp
The Type= field
sets the type information
used in MIME error messages
as defined by
RFC 1894.
It is actually three values separated by slashes:
the MTA-type (that is, the description of how hosts are named),
the address type (the description of e-mail addresses),
and the diagnostic type (the description of error diagnostic codes).
Each of these must be a registered value
or begin with
.q X\- .
The default is
.q dns/rfc822/smtp .
.pp
The m= field specifies the maximum number of messages
to attempt to deliver on a single SMTP or LMTP connection.
The default is infinite.
.pp
The r= field specifies the maximum number of recipients
to attempt to deliver in a single envelope.
It defaults to 100.
.pp
The /= field specifies a new root directory for the mailer. The path is
macro expanded and then passed to the
.q chroot
system call. The root directory is changed before the Directory field is
consulted or the uid is changed.
.pp
The Wait= field specifies the maximum time to wait for the
mailer to return after sending all data to it.
This applies to mailers that have been forked by
.i sendmail .
.pp
The Queuegroup= field specifies the default queue group in which
received mail should be queued.
This can be overridden by other means as explained in section
``Queue Groups and Queue Directories''.
.sh 2 "H \*- Define Header"
.pp
The format of the header lines that
.i sendmail
inserts into the message
are defined by the
.b H
line.
The syntax of this line is one of the following:
.(b F
.b H \c
.i hname \c
.b :
.i htemplate
.)b
.(b F
.b H [\c
.b ? \c
.i mflags \c
.b ? \c
.b ]\c
.i hname \c
.b :
.i htemplate
.)b
.(b F
.b H [\c
.b ?$ \c
.i {macro} \c
.b ? \c
.b ]\c
.i hname \c
.b :
.i htemplate
.)b
Continuation lines in this spec
are reflected directly into the outgoing message.
The
.i htemplate
is macro-expanded before insertion into the message.
If the
.i mflags
(surrounded by question marks)
are specified,
at least one of the specified flags
must be stated in the mailer definition
for this header to be automatically output.
If a
.i ${macro}
(surrounded by question marks)
is specified,
the header will be automatically output
if the macro is set.
The macro may be set using any of the normal methods,
including using the
.b macro
storage map in a ruleset.
If one of these headers is in the input
it is reflected to the output
regardless of these flags or macros.
Notice:
If a
.i ${macro}
is used to set a header, then it is useful to add that macro to class
.i $={persistentMacros}
which consists of the macros that should be saved across queue runs.
.pp
Some headers have special semantics
that will be described later.
.pp
A secondary syntax allows validation of headers as they are being read.
To enable validation, use:
.(b
.b H \c
.i Header \c
.b ": $>" \c
.i Ruleset
.b H \c
.i Header \c
.b ": $>+" \c
.i Ruleset
.)b
The indicated
.i Ruleset
is called for the specified
.i Header ,
and can return
.b $#error
to reject or quarantine the message or
.b $#discard
to discard the message
(as with the other
.b check_ *
rulesets).
The ruleset receives the header field-body as argument,
i.e., not the header field-name; see also
${hdr_name} and ${currHeader}.
The header is treated as a structured field,
that is,
text in parentheses is deleted before processing,
unless the second form
.b $>+
is used.
Note: only one ruleset can be associated with a header;
.i sendmail
will silently ignore multiple entries.
.pp
For example, the configuration lines:
.(b
HMessage-Id: $>CheckMessageId
SCheckMessageId
R< $+ @ $+ > $@ OK
R$* $#error $: Illegal Message-Id header
.)b
would refuse any message that had a Message-Id: header of any of the
following forms:
.(b
Message-Id: <>
Message-Id: some text
Message-Id: <legal text@domain> extra crud
.)b
A default ruleset that is called for headers which don't have a
specific ruleset defined for them can be specified by:
.(b
.b H \c
.i * \c
.b ": $>" \c
.i Ruleset
.)b
or
.(b
.b H \c
.i * \c
.b ": $>+" \c
.i Ruleset
.)b
.sh 2 "O \*- Set Option"
.pp
There are a number of global options that
can be set from a configuration file.
Options are represented by full words;
some are also representable as single characters for back compatibility.
The syntax of this line is:
.(b F
.b O \0
.i option \c
.b = \c
.i value
.)b
This sets option
.i option
to be
.i value .
Note that there
.i must
be a space between the letter `O' and the name of the option.
An older version is:
.(b F
.b O \c
.i o\|value
.)b
where the option
.i o
is a single character.
Depending on the option,
.i value
may be a string, an integer,
a boolean
(with legal values
.q t ,
.q T ,
.q f ,
or
.q F ;
the default is TRUE),
or
a time interval.
.pp
All filenames used in options should be absolute paths,
i.e., starting with '/'.
Relative filenames most likely cause surprises during operation
(unless otherwise noted).
.pp
The options supported (with the old, one character names in brackets) are:
.nr ii 1i
.ip "AliasFile=\fIspec, spec, ...\fP"
[A]
Specify possible alias file(s).
Each
.i spec
should be in the format
``\c
.i class \c
.b :
.i info ''
where
.i class \c
.b :
is optional and defaults to ``implicit''.
Note that
.i info
is required for all
.i class es
except
.q ldap .
For the
.q ldap
class,
if
.i info
is not specified,
a default
.i info
value is used as follows:
.(b
\-k (&(objectClass=sendmailMTAAliasObject)
(sendmailMTAAliasName=aliases)
(|(sendmailMTACluster=${sendmailMTACluster})
(sendmailMTAHost=$j))
(sendmailMTAKey=%0))
\-v sendmailMTAAliasValue
.)b
Depending on how
.i sendmail
is compiled, valid classes are
.q implicit
(search through a compiled-in list of alias file types,
for back compatibility),
.q hash
(if
.sm NEWDB
is specified),
.q btree
(if
.sm NEWDB
is specified),
.q dbm
(if
.sm NDBM
is specified),
.q cdb
(if
.sm CDB
is specified),
.q stab
(internal symbol table \*- not normally used
unless you have no other database lookup),
.q sequence
(use a sequence of maps
previously declared),
.q ldap
(if
.sm LDAPMAP
is specified),
or
.q nis
(if
.sm NIS
is specified).
If a list of
.i spec s
are provided,
.i sendmail
searches them in order.
.ip AliasWait=\fItimeout\fP
[a]
If set,
wait up to
.i timeout
(units default to minutes)
for an
.q @:@
entry to exist in the alias database
before starting up.
If it does not appear in the
.i timeout
interval issue a warning.
.ip AllowBogusHELO
[no short name]
If set, allow HELO SMTP commands that don't include a host name.
Setting this violates RFC 1123 section 5.2.5,
but is necessary to interoperate with several SMTP clients.
If there is a value, it is still checked for legitimacy.
.ip AuthMaxBits=\fIN\fP
[no short name]
Limit the maximum encryption strength for the security layer in
SMTP AUTH (SASL). Default is essentially unlimited.
This allows to turn off additional encryption in SASL if
STARTTLS is already encrypting the communication, because the
existing encryption strength is taken into account when choosing
an algorithm for the security layer.
For example, if STARTTLS is used and the symmetric cipher is 3DES,
-then the the keylength (in bits) is 168.
+then the keylength (in bits) is 168.
Hence setting
.b AuthMaxBits
to 168 will disable any encryption in SASL.
.ip AuthMechanisms
[no short name]
List of authentication mechanisms for AUTH (separated by spaces).
The advertised list of authentication mechanisms will be the
intersection of this list and the list of available mechanisms as
determined by the Cyrus SASL library.
If STARTTLS is active, EXTERNAL will be added to this list.
In that case, the value of {cert_subject} is used as authentication id.
.ip AuthOptions
[no short name]
List of options for SMTP AUTH consisting of single characters
with intervening white space or commas.
.(b
.ta 4n
-A Use the AUTH= parameter for the MAIL FROM
+A Use the AUTH= parameter for the MAIL
command only when authentication succeeded.
This can be used as a workaround for broken
MTAs that do not implement RFC 2554 correctly.
a protection from active (non-dictionary) attacks
during authentication exchange.
c require mechanisms which pass client credentials,
and allow mechanisms which can pass credentials
to do so.
d don't permit mechanisms susceptible to passive
dictionary attack.
f require forward secrecy between sessions
(breaking one won't help break next).
m require mechanisms which provide mutual authentication
(only available if using Cyrus SASL v2 or later).
p don't permit mechanisms susceptible to simple
passive attack (e.g., PLAIN, LOGIN), unless a
security layer is active.
y don't permit mechanisms that allow anonymous login.
.)b
The first option applies to sendmail as a client, the others to a server.
Example:
.(b
O AuthOptions=p,y
.)b
would disallow ANONYMOUS as AUTH mechanism and would
allow PLAIN and LOGIN only if a security layer (e.g.,
provided by STARTTLS) is already active.
The options 'a', 'c', 'd', 'f', 'p', and 'y' refer to properties of the
selected SASL mechanisms.
Explanations of these properties can be found in the Cyrus SASL documentation.
.ip AuthRealm
[no short name]
The authentication realm that is passed to the Cyrus SASL library.
If no realm is specified,
.b $j
is used.
See also KNOWNBUGS.
.ip BadRcptThrottle=\fIN\fP
[no short name]
If set and the specified number of recipients in a single SMTP
transaction have been rejected, sleep for one second after each subsequent
RCPT command in that transaction.
.ip BlankSub=\fIc\fP
[B]
Set the blank substitution character to
.i c .
Unquoted spaces in addresses are replaced by this character.
Defaults to space (i.e., no change is made).
.ip CACertPath
[no short name]
Path to directory with certificates of CAs.
This directory directory must contain the hashes of each CA certificate
as filenames (or as links to them).
.ip CACertFile
[no short name]
File containing one or more CA certificates;
see section about STARTTLS for more information.
.ip CertFingerprintAlgorithm
Specify the fingerprint algorithm (digest) to use for the presented cert.
If the option is not set,
md5 is used and the macro
.b ${cert_md5}
contains the cert fingerprint.
If the option is explicitly set,
the specified algorithm (e.g., sha1) is used
and the macro
.b ${cert_fp}
contains the cert fingerprint.
.ip CipherList
Specify cipher list for STARTTLS (does not apply to TLSv1.3).
See
.i ciphers (1)
for possible values.
.ip CheckAliases
[n]
Validate the RHS of aliases when rebuilding the alias database.
.ip CheckpointInterval=\fIN\fP
[C]
Checkpoints the queue every
.i N
(default 10)
addresses sent.
If your system crashes during delivery to a large list,
this prevents retransmission to any but the last
.i N
recipients.
.ip ClassFactor=\fIfact\fP
[z]
The indicated
.i fact or
is multiplied by the message class
(determined by the Precedence: field in the user header
and the
.b P
lines in the configuration file)
and subtracted from the priority.
Thus, messages with a higher Priority: will be favored.
Defaults to 1800.
.ip ClientCertFile
[no short name]
File containing the certificate of the client, i.e., this certificate
is used when
.i sendmail
acts as client (for STARTTLS).
.ip ClientKeyFile
[no short name]
File containing the private key belonging to the client certificate
(for STARTTLS if
.i sendmail
runs as client).
.ip ClientPortOptions=\fIoptions\fP
-[O]
+[no short name]
Set client SMTP options.
The options are
.i key=value
pairs separated by commas.
Known keys are:
.(b
.ta 1i
Port Name/number of source port for connection (defaults to any free port)
Addr Address mask (defaults INADDR_ANY)
Family Address family (defaults to INET)
SndBufSize Size of TCP send buffer
RcvBufSize Size of TCP receive buffer
Modifier Options (flags) for the client
.)b
The
.i Addr ess
mask may be a numeric address in IPv4 dot notation or IPv6 colon notation
or a network name.
Note that if a network name is specified,
only the first IP address returned for it will be used.
This may cause indeterminate behavior for network names
that resolve to multiple addresses.
Therefore, use of an address is recommended.
.i Modifier
can be the following character:
.(b
.ta 1i
h use name of interface for HELO command
A don't use AUTH when sending e-mail
S don't use STARTTLS when sending e-mail
.)b
If ``h'' is set, the name corresponding to the outgoing interface
address (whether chosen via the Connection parameter or
the default) is used for the HELO/EHLO command.
However, the name must not start with a square bracket
and it must contain at least one dot.
This is a simple test whether the name is not
an IP address (in square brackets) but a qualified hostname.
Note that multiple ClientPortOptions settings are allowed
in order to give settings for each protocol family
(e.g., one for Family=inet and one for Family=inet6).
A restriction placed on one family only affects
outgoing connections on that particular family.
.ip ClientSSLOptions
A space or comma separated list of SSL related options for the client side.
See
.i SSL_CTX_set_options (3)
for a list;
the available values depend on the OpenSSL version against which
.i sendmail
is compiled.
By default,
.i SSL_OP_ALL
.i SSL_OP_NO_SSLv2
.i SSL_OP_NO_TICKET
.i -SSL_OP_TLSEXT_PADDING
are used
(if those options are available).
Options can be cleared by preceding them with a minus sign.
It is also possible to specify numerical values, e.g.,
.b -0x0010 .
.ip ColonOkInAddr
[no short name]
If set, colons are acceptable in e-mail addresses
(e.g.,
.q host:user ).
If not set, colons indicate the beginning of a RFC 822 group construct
(\c
.q "groupname: member1, member2, ... memberN;" ).
Doubled colons are always acceptable
(\c
.q nodename::user )
and proper route-addr nesting is understood
(\c
.q <@relay:user@host> ).
Furthermore, this option defaults on if the configuration version level
is less than 6 (for back compatibility).
However, it must be off for full compatibility with RFC 822.
.ip ConnectionCacheSize=\fIN\fP
[k]
The maximum number of open connections that will be cached at a time.
The default is one.
This delays closing the current connection until
either this invocation of
.i sendmail
needs to connect to another host
or it terminates.
Setting it to zero defaults to the old behavior,
that is, connections are closed immediately.
Since this consumes file descriptors,
the connection cache should be kept small:
4 is probably a practical maximum.
.ip ConnectionCacheTimeout=\fItimeout\fP
[K]
The maximum amount of time a cached connection will be permitted to idle
without activity.
If this time is exceeded,
the connection is immediately closed.
This value should be small (on the order of ten minutes).
Before
.i sendmail
uses a cached connection,
it always sends a RSET command
to check the connection;
if this fails, it reopens the connection.
This keeps your end from failing if the other end times out.
The point of this option is to be a good network neighbor
and avoid using up excessive resources
on the other end.
The default is five minutes.
.ip ConnectOnlyTo=\fIaddress\fP
[no short name]
This can be used to
override the connection address (for testing purposes).
.ip ConnectionRateThrottle=\fIN\fP
[no short name]
If set to a positive value,
allow no more than
.i N
incoming connections in a one second period per daemon.
This is intended to flatten out peaks
and allow the load average checking to cut in.
Defaults to zero (no limits).
.ip ConnectionRateWindowSize=\fIN\fP
[no short name]
Define the length of the interval for which
the number of incoming connections is maintained.
The default is 60 seconds.
.ip ControlSocketName=\fIname\fP
[no short name]
Name of the control socket for daemon management.
A running
.i sendmail
daemon can be controlled through this named socket.
Available commands are:
.i help,
.i mstat,
.i restart,
.i shutdown,
and
.i status.
The
.i status
command returns the current number of daemon children,
the maximum number of daemon children,
the free disk space (in blocks) of the queue directory,
and the load average of the machine expressed as an integer.
If not set, no control socket will be available.
Solaris and pre-4.4BSD kernel users should see the note in sendmail/README .
.ip CRLFile=\fIname\fP
[no short name]
Name of file that contains certificate
revocation status, useful for X.509v3 authentication.
Note: if a CRLFile is specified but the file is unusable,
STARTTLS is disabled.
.ip CRLPath=\fIname\fP
[no short name]
Name of directory that contains hashes pointing to
certificate revocation status files.
Symbolic links can be generated with the following
two (Bourne) shell commands:
.(b
C=FileName_of_CRL
ln -s $C `openssl crl -noout -hash < $C`.r0
.)b
.ip DHParameters
This option applies to the server side only.
Possible values are:
.(b
.ta 2i
5 use precomputed 512 bit prime.
1 generate 1024 bit prime
2 generate 2048 bit prime.
i use included precomputed 2048 bit prime (default).
none do not use Diffie-Hellman.
/path/to/file load prime from file.
.)b
This is only required if a ciphersuite containing DSA/DH is used.
The default is ``i'' which selects a precomputed, fixed 2048 bit prime.
If ``5'' is selected, then precomputed, fixed primes are used.
Note: this option should not be used
(unless necessary for compatibility with old implementations).
If ``1'' or ``2'' is selected, then prime values are computed during startup.
Note: this operation can take a significant amount of time on a
slow machine (several seconds), but it is only done once at startup.
If ``none'' is selected, then TLS ciphersuites containing DSA/DH
cannot be used.
If a file name is specified (which must be an absolute path),
then the primes are read from it.
It is recommended to generate such a file using a command like this:
.(b
openssl dhparam -out /etc/mail/dhparams.pem 2048
.)b
If the file is not readable or contains unusable data,
the default ``i'' is used instead.
.ip DaemonPortOptions=\fIoptions\fP
[O]
Set server SMTP options.
Each instance of
.b DaemonPortOptions
leads to an additional incoming socket.
The options are
.i key=value
pairs.
Known keys are:
.(b
.ta 1i
Name User-definable name for the daemon (defaults to "Daemon#")
Port Name/number of listening port (defaults to "smtp")
Addr Address mask (defaults INADDR_ANY)
Family Address family (defaults to INET)
InputMailFilters List of input mail filters for the daemon
Listen Size of listen queue (defaults to 10)
Modifier Options (flags) for the daemon

.)b
The
.i Name
key is used for error messages and logging.
The
.i Addr ess
mask may be
a numeric address in IPv4 dot notation or IPv6 colon notation,
or a network name,
or a path to a local socket.
Note that if a network name is specified,
only the first IP address returned for it will be used.
This may cause indeterminate behavior for network names
that resolve to multiple addresses.
Therefore, use of an address is recommended.
The
.i Family
key defaults to INET (IPv4).
IPv6 users who wish to also accept IPv6 connections
should add additional Family=inet6
.b DaemonPortOptions
lines.
For a local socket, use
Family=local
or
Family=unix.
The
.i InputMailFilters
key overrides the default list of input mail filters listed in the
.b InputMailFilters
option.
If multiple input mail filters are required, they must be separated
by semicolons (not commas).
.i Modifier
can be a sequence (without any delimiters)
of the following characters:
.(b
.ta 1i
a always require AUTH
b bind to interface through which mail has been received
c perform hostname canonification (.cf)
f require fully qualified hostname (.cf)
s Run smtps (SMTP over SSL) instead of smtp
u allow unqualified addresses (.cf)
A disable AUTH (overrides 'a' modifier)
C don't perform hostname canonification
E disallow ETRN (see RFC 2476)
O optional; if opening the socket fails ignore it
S don't offer STARTTLS
.)b
That is, one way to specify a message submission agent (MSA) that
always requires AUTH is:
.(b
O DaemonPortOptions=Name=MSA, Port=587, M=Ea
.)b
The modifiers that are marked with "(.cf)" have only
effect in the standard configuration file, in which
they are available via
.b ${daemon_flags} .
Notice: Do
.b not
use the ``a'' modifier on a public accessible MTA!
It should only be used for a MSA that is accessed by authorized
users for initial mail submission.
Users must authenticate to use a MSA which has this option turned on.
The flags ``c'' and ``C'' can change the default for
hostname canonification in the
.i sendmail.cf
file.
See the relevant documentation for
.sm FEATURE(nocanonify) .
The modifier ``f'' disallows addresses of the form
.b user@host
unless they are submitted directly.
The flag ``u'' allows unqualified sender addresses,
i.e., those without @host.
``b'' forces sendmail to bind to the interface
through which the e-mail has been
received for the outgoing connection.
.b WARNING:
Use ``b''
only if outgoing mail can be routed through the incoming connection's
interface to its destination. No attempt is made to catch problems due to a
misconfiguration of this parameter, use it only for virtual hosting
where each virtual interface can connect to every possible location.
This will also override possible settings via
.b ClientPortOptions.
Note,
.i sendmail
will listen on a new socket
for each occurrence of the
.b DaemonPortOptions
option in a configuration file.
The modifier ``O'' causes sendmail to ignore a socket
if it can't be opened.
This applies to failures from the socket(2) and bind(2) calls.
.ip DefaultAuthInfo
[no short name]
Filename that contains default authentication information for outgoing
connections. This file must contain the user id, the authorization id,
the password (plain text), the realm and the list of mechanisms to use
on separate lines and must be readable by
root (or the trusted user) only.
If no realm is specified,
.b $j
is used.
If no mechanisms are specified, the list given by
.b AuthMechanisms
is used.
Notice: this option is deprecated and will be removed in future versions.
Moreover, it doesn't work for the MSP since it can't read the file
(the file must not be group/world-readable otherwise
.i sendmail
will complain).
Use the authinfo ruleset instead which provides more control over
the usage of the data anyway.
.ip DefaultCharSet=\fIcharset\fP
[no short name]
When a message that has 8-bit characters but is not in MIME format
is converted to MIME
(see the EightBitMode option)
a character set must be included in the Content-Type: header.
This character set is normally set from the Charset= field
of the mailer descriptor.
If that is not set, the value of this option is used.
If this option is not set, the value
.q unknown-8bit
is used.
.ip DataFileBufferSize=\fIthreshold\fP
[no short name]
Set the
.i threshold ,
in bytes,
before a memory-based
queue data file
becomes disk-based.
The default is 4096 bytes.
.ip DeadLetterDrop=\fIfile\fP
[no short name]
Defines the location of the system-wide dead.letter file,
formerly hardcoded to /usr/tmp/dead.letter.
If this option is not set (the default),
sendmail will not attempt to save to a system-wide dead.letter file
in the event
it cannot bounce the mail to the user or postmaster.
Instead, it will rename the qf file
as it has in the past
when the dead.letter file could not be opened.
.ip DefaultUser=\fIuser:group\fP
[u]
Set the default userid for mailers to
.i user:group .
If
.i group
is omitted and
.i user
is a user name
(as opposed to a numeric user id)
the default group listed in the /etc/passwd file for that user is used
as the default group.
Both
.i user
and
.i group
may be numeric.
Mailers without the
.i S
flag in the mailer definition
will run as this user.
Defaults to 1:1.
The value can also be given as a symbolic user name.\**
.(f
\**The old
.b g
option has been combined into the
.b DefaultUser
option.
.)f
.ip DelayLA=\fILA\fP
[no short name]
When the system load average exceeds
.i LA ,
.i sendmail
will sleep for one second on most SMTP commands and
before accepting connections.
.ip DeliverByMin=\fItime\fP
-[0]
+[no short name]
Set minimum time for Deliver By SMTP Service Extension (RFC 2852).
If 0, no time is listed, if less than 0, the extension is not offered,
if greater than 0, it is listed as minimum time
for the EHLO keyword DELIVERBY.
.ip DeliveryMode=\fIx\fP
[d]
Deliver in mode
.i x .
Legal modes are:
.(b
.ta 4n
i Deliver interactively (synchronously)
b Deliver in background (asynchronously)
q Just queue the message (deliver during queue run)
d Defer delivery and all map lookups (deliver during queue run)
.)b
Defaults to ``b'' if no option is specified,
``i'' if it is specified but given no argument
(i.e., ``Od'' is equivalent to ``Odi'').
The
.b \-v
command line flag sets this to
.b i .
Note: for internal reasons,
``i'' does not work
if a milter is enabled which can reject or delete recipients.
In that case the mode will be changed to ``b''.
.ip DialDelay=\fIsleeptime\fP
[no short name]
Dial-on-demand network connections can see timeouts
if a connection is opened before the call is set up.
If this is set to an interval and a connection times out
on the first connection being attempted
.i sendmail
will sleep for this amount of time and try again.
This should give your system time to establish the connection
to your service provider.
Units default to seconds, so
.q DialDelay=5
uses a five second delay.
Defaults to zero
(no retry).
This delay only applies to mailers which have the
Z flag set.
.ip DirectSubmissionModifiers=\fImodifiers\fP
Defines
.b ${daemon_flags}
for direct (command line) submissions.
If not set,
.b ${daemon_flags}
is either "CC f" if the option
.b \-G
is used or "c u" otherwise.
-Note that only the the "CC", "c", "f", and "u" flags are checked.
+Note that only the "CC", "c", "f", and "u" flags are checked.
.ip DontBlameSendmail=\fIoption,option,...\fP
[no short name]
In order to avoid possible cracking attempts
caused by world- and group-writable files and directories,
.i sendmail
does paranoid checking when opening most of its support files.
If for some reason you absolutely must run with,
for example,
a group-writable
.i /etc
directory,
then you will have to turn off this checking
(at the cost of making your system more vulnerable to attack).
The possible arguments have been described earlier.
The details of these flags are described above.
.\"XXX should have more here!!! XXX
.b "Use of this option is not recommended."
.ip DontExpandCnames
[no short name]
The standards say that all host addresses used in a mail message
must be fully canonical.
For example, if your host is named
.q Cruft.Foo.ORG
and also has an alias of
.q FTP.Foo.ORG ,
the former name must be used at all times.
This is enforced during host name canonification
($[ ... $] lookups).
If this option is set, the protocols are ignored and the
.q wrong
thing is done.
However, the IETF is moving toward changing this standard,
so the behavior may become acceptable.
Please note that hosts downstream may still rewrite the address
to be the true canonical name however.
.ip DontInitGroups
[no short name]
If set,
.i sendmail
will avoid using the initgroups(3) call.
If you are running NIS,
this causes a sequential scan of the groups.byname map,
which can cause your NIS server to be badly overloaded in a large domain.
The cost of this is that the only group found for users
will be their primary group (the one in the password file),
which will make file access permissions somewhat more restrictive.
Has no effect on systems that don't have group lists.
.ip DontProbeInterfaces
[no short name]
.i Sendmail
normally finds the names of all interfaces active on your machine
when it starts up
and adds their name to the
.b $=w
class of known host aliases.
If you have a large number of virtual interfaces
or if your DNS inverse lookups are slow
this can be time consuming.
This option turns off that probing.
However, you will need to be certain to include all variant names
in the
.b $=w
class by some other mechanism.
If set to
.b loopback ,
loopback interfaces (e.g., lo0) will not be probed.
.ip DontPruneRoutes
[R]
Normally,
.i sendmail
tries to eliminate any unnecessary explicit routes
when sending an error message
(as discussed in RFC 1123 \(sc 5.2.6).
For example,
when sending an error message to
.(b
<@known1,@known2,@known3:user@unknown>
.)b
.i sendmail
will strip off the
.q @known1,@known2
in order to make the route as direct as possible.
However, if the
.b R
option is set, this will be disabled,
and the mail will be sent to the first address in the route,
even if later addresses are known.
This may be useful if you are caught behind a firewall.
.ip DoubleBounceAddress=\fIerror-address\fP
[no short name]
If an error occurs when sending an error message,
send the error report
(termed a
.q "double bounce"
because it is an error
.q bounce
that occurs when trying to send another error
.q bounce )
to the indicated address.
The address is macro expanded
at the time of delivery.
If not set, defaults to
.q postmaster .
If set to an empty string, double bounces are dropped.
.ip EightBitMode=\fIaction\fP
[8]
Set handling of eight-bit data.
There are two kinds of eight-bit data:
that declared as such using the
.b BODY=8BITMIME
ESMTP declaration or the
.b \-B8BITMIME
command line flag,
and undeclared 8-bit data, that is,
input that just happens to be eight bits.
There are three basic operations that can happen:
undeclared 8-bit data can be automatically converted to 8BITMIME,
undeclared 8-bit data can be passed as-is without conversion to MIME
(``just send 8''),
and declared 8-bit data can be converted to 7-bits
for transmission to a non-8BITMIME mailer.
The possible
.i action s
are:
.(b
.\" r Reject undeclared 8-bit data;
.\" don't convert 8BITMIME\(->7BIT (``reject'')
s Reject undeclared 8-bit data (``strict'')
.\" do convert 8BITMIME\(->7BIT (``strict'')
.\" c Convert undeclared 8-bit data to MIME;
.\" don't convert 8BITMIME\(->7BIT (``convert'')
m Convert undeclared 8-bit data to MIME (``mime'')
.\" do convert 8BITMIME\(->7BIT (``mime'')
.\" j Pass undeclared 8-bit data;
.\" don't convert 8BITMIME\(->7BIT (``just send 8'')
p Pass undeclared 8-bit data (``pass'')
.\" do convert 8BITMIME\(->7BIT (``pass'')
.\" a Adaptive algorithm: see below
.)b
.\"The adaptive algorithm is to accept 8-bit data,
.\"converting it to 8BITMIME only if the receiver understands that,
.\"otherwise just passing it as undeclared 8-bit data;
.\"8BITMIME\(->7BIT conversions are done.
In all cases properly declared 8BITMIME data will be converted to 7BIT
as needed.
.p
Note: if an automatic conversion is performed, a header with
the following format will be added:
.(b
X-MIME-Autoconverted: from OLD to NEW by $j id $i
.)b
where
.\" format?
OLD
and
NEW
describe the original format and the converted format, respectively.
.ip ErrorHeader=\fIfile-or-message\fP
[E]
Prepend error messages with the indicated message.
If it begins with a slash,
it is assumed to be the pathname of a file
containing a message (this is the recommended setting).
Otherwise, it is a literal message.
The error file might contain the name, email address, and/or phone number
of a local postmaster who could provide assistance
to end users.
If the option is missing or null,
or if it names a file which does not exist or which is not readable,
no message is printed.
.ip ErrorMode=\fIx\fP
[e]
Dispose of errors using mode
.i x .
The values for
.i x
are:
.(b
p Print error messages (default)
q No messages, just give exit status
m Mail back errors
w Write back errors (mail if user not logged in)
e Mail back errors (when applicable) and give zero exit stat always
.)b
Note that the last mode,
.q e ,
is for Berknet error processing and
should not be used in normal circumstances.
Note, too, that mode
.q q ,
only applies to errors recognized before sendmail forks for
background delivery.
.ip FallbackMXhost=\fIfallbackhost\fP
[V]
If specified, the
.i fallbackhost
acts like a very low priority MX
on every host.
MX records will be looked up for this host,
unless the name is surrounded by square brackets.
This is intended to be used by sites with poor network connectivity.
Messages which are undeliverable due to temporary address failures
(e.g., DNS failure)
also go to the FallbackMXhost.
.ip FallBackSmartHost=\fIhostname\fP
If specified, the
.i FallBackSmartHost
will be used in a last-ditch effort for each host.
This is intended to be used by sites with "fake internal DNS",
e.g., a company whose DNS accurately reflects the world
inside that company's domain but not outside.
.ip FastSplit
[no short name]
If set to a value greater than zero (the default is one),
it suppresses the MX lookups on addresses
when they are initially sorted, i.e., for the first delivery attempt.
This usually results in faster envelope splitting unless the MX records
are readily available in a local DNS cache.
To enforce initial sorting based on MX records set
.b FastSplit
to zero.
If the mail is submitted directly from the command line, then
the value also limits the number of processes to deliver the envelopes;
if more envelopes are created they are only queued up
and must be taken care of by a queue run.
Since the default submission method is via SMTP (either from a MUA
or via the MSP), the value of
.b FastSplit
is seldom used to limit the number of processes to deliver the envelopes.
.ip ForkEachJob
[Y]
If set,
deliver each job that is run from the queue in a separate process.
.ip ForwardPath=\fIpath\fP
[J]
Set the path for searching for users' .forward files.
The default is
.q $z/.forward .
Some sites that use the automounter may prefer to change this to
.q /var/forward/$u
to search a file with the same name as the user in a system directory.
It can also be set to a sequence of paths separated by colons;
.i sendmail
stops at the first file it can successfully and safely open.
For example,
.q /var/forward/$u:$z/.forward
will search first in /var/forward/\c
.i username
and then in
.i ~username /.forward
(but only if the first file does not exist).
.ip HeloName=\fIname\fP
[no short name]
Set the name to be used for HELO/EHLO (instead of $j).
.ip HelpFile=\fIfile\fP
[H]
Specify the help file for SMTP.
If no file name is specified, "helpfile" is used.
+If the help file does not exist (cannot be opened for reading)
+.i sendmail
+will print a note including its version in response to a
+.b HELP
+command.
+To avoid providing this information to a client specify an empty file.
.ip HoldExpensive
[c]
If an outgoing mailer is marked as being expensive,
don't connect immediately.
.ip HostsFile=\fIpath\fP
[no short name]
The path to the hosts database,
normally
.q /etc/hosts .
This option is only consulted when sendmail
is canonifying addresses,
and then only when
.q files
is in the
.q hosts
service switch entry.
In particular, this file is
.i never
used when looking up host addresses;
that is under the control of the system
.i gethostbyname (3)
routine.
.ip HostStatusDirectory=\fIpath\fP
[no short name]
The location of the long term host status information.
When set,
information about the status of hosts
(e.g., host down or not accepting connections)
will be shared between all
.i sendmail
processes;
normally, this information is only held within a single queue run.
This option requires a connection cache of at least 1 to function.
If the option begins with a leading `/',
it is an absolute pathname;
otherwise,
it is relative to the mail queue directory.
A suggested value for sites desiring persistent host status is
.q \&.hoststat
(i.e., a subdirectory of the queue directory).
.ip IgnoreDots
[i]
Ignore dots in incoming messages.
This is always disabled (that is, dots are always accepted)
when reading SMTP mail.
.ip InputMailFilters=\fIname,name,...\fP
A comma separated list of filters which determines which filters
(see the "X \*- Mail Filter (Milter) Definitions" section)
and the invocation sequence are contacted for incoming SMTP messages.
If none are set, no filters will be contacted.
.ip LDAPDefaultSpec=\fIspec\fP
[no short name]
Sets a default map specification for LDAP maps.
The value should only contain LDAP specific settings
such as
.q "-h host -p port -d bindDN" .
The settings will be used for all LDAP maps
unless the individual map specification overrides a setting.
This option should be set before any LDAP maps are defined.
.ip LogLevel=\fIn\fP
[L]
Set the log level to
.i n .
Defaults to 9.
.ip M\fIx\|value\fP
[no long version]
Set the macro
.i x
to
.i value .
This is intended only for use from the command line.
The
.b \-M
flag is preferred.
.ip MailboxDatabase
[no short name]
Type of lookup to find information about local mailboxes,
defaults to ``pw'' which uses
.i getpwnam .
Other types can be introduced by adding them to the source code,
see libsm/mbdb.c for details.
.ip UseMSP
[no short name]
Use as mail submission program, i.e.,
allow group writable queue files
if the group is the same as that of a set-group-ID sendmail binary.
See the file
.b sendmail/SECURITY
in the distribution tarball.
.ip MatchGECOS
[G]
Allow fuzzy matching on the GECOS field.
If this flag is set,
and the usual user name lookups fail
(that is, there is no alias with this name and a
.i getpwnam
fails),
sequentially search the password file
for a matching entry in the GECOS field.
This also requires that MATCHGECOS
be turned on during compilation.
This option is not recommended.
.ip MaxAliasRecursion=\fIN\fP
[no short name]
The maximum depth of alias recursion (default: 10).
.ip MaxDaemonChildren=\fIN\fP
[no short name]
If set,
.i sendmail
will refuse connections when it has more than
.i N
children processing incoming mail or automatic queue runs.
This does not limit the number of outgoing connections.
If the default
.b DeliveryMode
(background) is used, then
.i sendmail
may create an almost unlimited number of children
(depending on the number of transactions and the
relative execution times of mail receiption and mail delivery).
If the limit should be enforced, then a
.b DeliveryMode
other than background must be used.
If not set, there is no limit to the number of children --
that is, the system load average controls this.
.ip MaxHeadersLength=\fIN\fP
[no short name]
If set to a value greater than zero it specifies
the maximum length of the sum of all headers.
This can be used to prevent a denial of service attack.
The default is 32K.
.ip MaxHopCount=\fIN\fP
[h]
The maximum hop count.
Messages that have been processed more than
.i N
times are assumed to be in a loop and are rejected.
Defaults to 25.
.ip MaxMessageSize=\fIN\fP
[no short name]
Specify the maximum message size
to be advertised in the ESMTP EHLO response.
Messages larger than this will be rejected.
If set to a value greater than zero,
that value will be listed in the SIZE response,
otherwise SIZE is advertised in the ESMTP EHLO response
without a parameter.
.ip MaxMimeHeaderLength=\fIN[/M]\fP
[no short name]
Sets the maximum length of certain MIME header field values to
.i N
characters.
These MIME header fields are determined by being a member of
class {checkMIMETextHeaders}, which currently contains only
the header Content-Description.
For some of these headers which take parameters,
the maximum length of each parameter is set to
.i M
if specified. If
.i /M
is not specified, one half of
.i N
will be used.
By default,
these values are 2048 and 1024, respectively.
To allow any length, a value of 0 can be specified.
.ip MaxNOOPCommands=\fIN\fP
Override the default of
.b MAXNOOPCOMMANDS
for the number of
.i useless
commands, see Section
"Measures against Denial of Service Attacks".
.ip MaxQueueChildren=\fIN\fP
[no short name]
When set, this limits the number of concurrent queue runner processes to
.i N.
This helps to control the amount of system resources used when processing
the queue. When there are multiple queue groups defined and the total number
of queue runners for these queue groups would exceed
.i MaxQueueChildren
then the queue groups will not all run concurrently. That is, some portion
of the queue groups will run concurrently such that
.i MaxQueueChildren
will not be exceeded, while the remaining queue groups will be run later (in
round robin order). See also
.i MaxRunnersPerQueue
and the section \fBQueue Group Declaration\fP.
Notice:
.i sendmail
does not count individual queue runners, but only sets of processes
that act on a workgroup.
Hence the actual number of queue runners may be lower than the limit
imposed by
.i MaxQueueChildren .
This discrepancy can be large if some queue runners have to wait
for a slow server and if short intervals are used.
.ip MaxQueueRunSize=\fIN\fP
[no short name]
The maximum number of jobs that will be processed
in a single queue run.
If not set, there is no limit on the size.
If you have very large queues or a very short queue run interval
this could be unstable.
However, since the first
.i N
jobs in queue directory order are run (rather than the
.i N
highest priority jobs)
this should be set as high as possible to avoid
.q losing
jobs that happen to fall late in the queue directory.
Note: this option also restricts the number of entries printed by
.i mailq .
That is, if
.i MaxQueueRunSize
is set to a value
.b N
larger than zero,
then only
.b N
entries are printed per queue group.
.ip MaxRecipientsPerMessage=\fIN\fP
[no short name]
The maximum number of recipients that will be accepted per message
in an SMTP transaction.
Note: setting this too low can interfere with sending mail from
MUAs that use SMTP for initial submission.
If not set, there is no limit on the number of recipients per envelope.
.ip MaxRunnersPerQueue=\fIN\fP
[no short name]
This sets the default maximum number of queue runners for queue groups.
Up to
.i N
queue runners will work in parallel on a queue group's messages.
This is useful where the processing of a message in the queue might
delay the processing of subsequent messages. Such a delay may be the result
of non-erroneous situations such as a low bandwidth connection.
May be overridden on a per queue group basis by setting the
.i Runners
option; see the section \fBQueue Group Declaration\fP.
The default is 1 when not set.
.ip MeToo
[m]
Send to me too,
even if I am in an alias expansion.
This option is deprecated
and will be removed from a future version.
.ip Milter
[no short name]
This option has several sub(sub)options.
The names of the suboptions are separated by dots.
At the first level the following options are available:
.(b
.ta \w'LogLevel'u+3n
LogLevel Log level for input mail filter actions, defaults to LogLevel.
macros Specifies list of macro to transmit to filters.
See list below.
.)b
The ``macros'' option has the following suboptions
which specify the list of macro to transmit to milters
after a certain event occurred.
.(b
.ta \w'envfrom'u+3n
connect After session connection start
helo After EHLO/HELO command
-envfrom After MAIL From command
-envrcpt After RCPT To command
+envfrom After MAIL command
+envrcpt After RCPT command
data After DATA command.
eoh After DATA command and header
eom After DATA command and terminating ``.''
.)b
By default the lists of macros are empty.
Example:
.(b
O Milter.LogLevel=12
O Milter.macros.connect=j, _, {daemon_name}
.)b
.ip MinFreeBlocks=\fIN\fP
[b]
Insist on at least
.i N
blocks free on the filesystem that holds the queue files
before accepting email via SMTP.
If there is insufficient space
.i sendmail
gives a 452 response
to the MAIL command.
This invites the sender to try again later.
.ip MaxQueueAge=\fIage\fP
[no short name]
If this is set to a value greater than zero,
entries in the queue will be retried during a queue run
only if the individual retry time has been reached
which is doubled for each attempt.
The maximum retry time is limited by the specified value.
.ip MinQueueAge=\fIage\fP
[no short name]
Don't process any queued jobs
that have been in the queue less than the indicated time interval.
This is intended to allow you to get responsiveness
by processing the queue fairly frequently
without thrashing your system by trying jobs too often.
The default units are minutes.
Note:
This option is ignored for queue runs that select a subset
of the queue, i.e.,
.q \-q[!][I|R|S|Q][string]
.ip MustQuoteChars=\fIs\fP
[no short name]
Sets the list of characters that must be quoted if used in a full name
that is in the phrase part of a ``phrase <address>'' syntax.
The default is ``\'.''.
The characters ``@,;:\e()[]'' are always added to this list.
Note: To avoid potential breakage of
DKIM signatures it is useful to set
.(b
O MustQuoteChars=.
.)b
Moreover, relaxed header signing should be used for DKIM signatures.
.ip NiceQueueRun
[no short name]
The priority of queue runners (nice(3)).
This value must be greater or equal zero.
.ip NoRecipientAction
[no short name]
The action to take when you receive a message that has no valid
recipient headers (To:, Cc:, Bcc:, or Apparently-To: \(em
the last included for back compatibility with old
.i sendmail s).
It can be
.b None
to pass the message on unmodified,
which violates the protocol,
.b Add-To
to add a To: header with any recipients it can find in the envelope
(which might expose Bcc: recipients),
.b Add-Apparently-To
to add an Apparently-To: header
(this is only for back-compatibility
and is officially deprecated),
.b Add-To-Undisclosed
to add a header
.q "To: undisclosed-recipients:;"
to make the header legal without disclosing anything,
or
.b Add-Bcc
to add an empty Bcc: header.
.ip OldStyleHeaders
[o]
Assume that the headers may be in old format,
i.e.,
spaces delimit names.
This actually turns on
an adaptive algorithm:
if any recipient address contains a comma, parenthesis,
or angle bracket,
it will be assumed that commas already exist.
If this flag is not on,
only commas delimit names.
Headers are always output with commas between the names.
Defaults to off.
.ip OperatorChars=\fIcharlist\fP
[$o macro]
The list of characters that are considered to be
.q operators ,
that is, characters that delimit tokens.
All operator characters are tokens by themselves;
sequences of non-operator characters are also tokens.
White space characters separate tokens
but are not tokens themselves \(em for example,
.q AAA.BBB
has three tokens, but
.q "AAA BBB"
has two.
If not set, OperatorChars defaults to
.q \&.\|:\|@\|[\|] ;
additionally, the characters
.q (\|)\|<\|>\|,\|;
are always operators.
Note that OperatorChars must be set in the
configuration file before any rulesets.
.ip PidFile=\fIfilename\fP
[no short name]
Filename of the pid file.
(default is _PATH_SENDMAILPID).
The
.i filename
is macro-expanded before it is opened, and unlinked when
.i sendmail
exits.
.ip PostmasterCopy=\fIpostmaster\fP
[P]
If set,
copies of error messages will be sent to the named
.i postmaster .
Only the header of the failed message is sent.
Errors resulting from messages with a negative precedence will not be sent.
Since most errors are user problems,
this is probably not a good idea on large sites,
and arguably contains all sorts of privacy violations,
but it seems to be popular with certain operating systems vendors.
The address is macro expanded
at the time of delivery.
Defaults to no postmaster copies.
.ip PrivacyOptions=\fI\|opt,opt,...\fP
[p]
Set the privacy
.i opt ions.
``Privacy'' is really a misnomer;
many of these are just a way of insisting on stricter adherence
to the SMTP protocol.
The
.i opt ions
can be selected from:
.(b
.ta \w'noactualrecipient'u+3n
public Allow open access
needmailhelo Insist on HELO or EHLO command before MAIL
needexpnhelo Insist on HELO or EHLO command before EXPN
noexpn Disallow EXPN entirely, implies noverb.
needvrfyhelo Insist on HELO or EHLO command before VRFY
novrfy Disallow VRFY entirely
noetrn Disallow ETRN entirely
noverb Disallow VERB entirely
restrictmailq Restrict mailq command
restrictqrun Restrict \-q command line flag
restrictexpand Restrict \-bv and \-v command line flags
noreceipts Don't return success DSNs\**
nobodyreturn Don't return the body of a message with DSNs
goaway Disallow essentially all SMTP status queries
authwarnings Put X-Authentication-Warning: headers in messages
and log warnings
noactualrecipient Don't put X-Actual-Recipient lines in DSNs
which reveal the actual account that addresses map to.
.)b
.(f
\**N.B.:
the
.b noreceipts
flag turns off support for RFC 1891
(Delivery Status Notification).
.)f
The
.q goaway
pseudo-flag sets all flags except
.q noreceipts ,
.q restrictmailq ,
.q restrictqrun ,
.q restrictexpand ,
.q noetrn ,
and
.q nobodyreturn .
If mailq is restricted,
only people in the same group as the queue directory
can print the queue.
If queue runs are restricted,
only root and the owner of the queue directory
can run the queue.
The
.q restrictexpand
pseudo-flag instructs
.i sendmail
to drop privileges when the
.b \-bv
option is given by users who are neither root nor the TrustedUser
so users cannot read private aliases, forwards, or :include: files.
It will add the
.q NonRootSafeAddr
to the
.q DontBlameSendmail
option to prevent misleading unsafe address warnings.
It also overrides the
.b \-v
(verbose) command line option to prevent information leakage.
Authentication Warnings add warnings about various conditions
that may indicate attempts to spoof the mail system,
such as using a non-standard queue directory.
.ip ProcessTitlePrefix=\fIstring\fP
[no short name]
Prefix the process title shown on 'ps' listings with
.i string .
The
.i string
will be macro processed.
.ip QueueDirectory=\fIdir\fP
[Q]
The QueueDirectory option serves two purposes.
First, it specifies the directory or set of directories that comprise
the default queue group.
Second, it specifies the directory D which is the ancestor of all queue
directories, and which sendmail uses as its current working directory.
When sendmail dumps core, it leaves its core files in D.
There are two cases.
If \fIdir\fR ends with an asterisk (eg, \fI/var/spool/mqueue/qd*\fR),
then all of the directories or symbolic links to directories
beginning with `qd' in
.i /var/spool/mqueue
will be used as queue directories of the default queue group,
and
.i /var/spool/mqueue
will be used as the working directory D.
Otherwise,
\fIdir\fR must name a directory (usually \fI/var/spool/mqueue\fR):
the default queue group consists of the single queue directory \fIdir\fR,
and the working directory D is set to \fIdir\fR.
To define additional groups of queue directories,
use the configuration file `Q' command.
Do not change the queue directory structure
while sendmail is running.
.ip QueueFactor=\fIfactor\fP
[q]
Use
.i factor
as the multiplier in the map function
to decide when to just queue up jobs rather than run them.
This value is divided by the difference between the current load average
and the load average limit
(\c
.b QueueLA
option)
to determine the maximum message priority
that will be sent.
Defaults to 600000.
.ip QueueLA=\fILA\fP
[x]
When the system load average exceeds
.i LA
and the
.b QueueFactor
(\c
.b q )
option divided by the difference in the current load average and the
.b QueueLA
option plus one
is less than the priority of the message,
just queue messages
(i.e., don't try to send them).
Defaults to 8 multiplied by
the number of processors online on the system
(if that can be determined).
.ip QueueFileMode=\fImode\fP
[no short name]
Default permissions for queue files (octal).
If not set, sendmail uses 0600 unless its real
and effective uid are different in which case it uses 0644.
.ip QueueSortOrder=\fIalgorithm\fP
[no short name]
Sets the
.i algorithm
used for sorting the queue.
Only the first character of the value is used.
Legal values are
.q host
(to order by the name of the first host name of the first recipient),
.q filename
(to order by the name of the queue file name),
.q time
(to order by the submission/creation time),
.q random
(to order randomly),
.q modification
(to order by the modification time of the qf file (older entries first)),
.q none
(to not order),
and
.q priority
(to order by message priority).
Host ordering makes better use of the connection cache,
but may tend to process low priority messages
that go to a single host
over high priority messages that go to several hosts;
it probably shouldn't be used on slow network links.
Filename and modification time ordering saves the overhead of
reading all of the queued items
before starting the queue run.
Creation (submission) time ordering is almost always a bad idea,
since it allows large, bulk mail to go out
before smaller, personal mail,
but may have applicability on some hosts with very fast connections.
Random is useful if several queue runners are started by hand
which try to drain the same queue since odds are they will be working
on different parts of the queue at the same time.
Priority ordering is the default.
.ip QueueTimeout=\fItimeout\fP
[T]
A synonym for
.q Timeout.queuereturn .
Use that form instead of the
.q QueueTimeout
form.
.ip RandFile
[no short name]
Name of file containing random data or the name of the UNIX socket
if EGD is used.
A (required) prefix "egd:" or "file:" specifies the type.
STARTTLS requires this filename if the compile flag HASURANDOMDEV is not set
(see sendmail/README).
.ip ResolverOptions=\fIoptions\fP
[I]
Set resolver options.
Values can be set using
.b + \c
.i flag
and cleared using
.b \- \c
.i flag ;
the
.i flag s
can be
.q debug ,
.q aaonly ,
.q usevc ,
.q primary ,
.q igntc ,
.q recurse ,
.q defnames ,
.q stayopen ,
.q use_inet6 ,
or
.q dnsrch .
The string
.q HasWildcardMX
(without a
.b +
or
.b \- )
can be specified to turn off matching against MX records
when doing name canonifications.
The string
.q WorkAroundBrokenAAAA
(without a
.b +
or
.b \- )
can be specified to work around some broken nameservers
which return SERVFAIL (a temporary failure) on T_AAAA (IPv6) lookups.
Notice: it might be necessary to apply the same (or similar) options to
.i submit.cf
too.
.ip RequiresDirfsync
[no short name]
This option can be used to override the compile time flag
.b REQUIRES_DIR_FSYNC
at runtime by setting it to
.sm false .
If the compile time flag is not set, the option is ignored.
The flag turns on support for file systems that require to call
.i fsync()
for a directory if the meta-data in it has been changed.
This should be turned on at least for older versions of ReiserFS;
it is enabled by default for Linux.
According to some information this flag is not needed
anymore for kernel 2.4.16 and newer.
.ip RrtImpliesDsn
-[R]
+[no short name]
If this option is set, a
.q Return-Receipt-To:
header causes the request of a DSN, which is sent to
the envelope sender as required by RFC 1891,
not to the address given in the header.
.ip RunAsUser=\fIuser\fP
[no short name]
The
.i user
parameter may be a user name
(looked up in
.i /etc/passwd )
or a numeric user id;
either form can have
.q ":group"
attached
(where group can be numeric or symbolic).
If set to a non-zero (non-root) value,
.i sendmail
will change to this user id shortly after startup\**.
.(f
\**When running as a daemon,
it changes to this user after accepting a connection
but before reading any
.sm SMTP
commands.
.)f
This avoids a certain class of security problems.
However, this means that all
.q \&.forward
and
.q :include:
files must be readable by the indicated
.i user
and all files to be written must be writable by
.i user
Also, all file and program deliveries will be marked unsafe
unless the option
.b DontBlameSendmail=NonRootSafeAddr
is set,
in which case the delivery will be done as
.i user .
It is also incompatible with the
.b SafeFileEnvironment
option.
In other words, it may not actually add much to security on an average system,
and may in fact detract from security
(because other file permissions must be loosened).
However, it should be useful on firewalls and other
places where users don't have accounts and the aliases file is
well constrained.
.ip RecipientFactor=\fIfact\fP
[y]
The indicated
.i fact or
is added to the priority (thus
.i lowering
the priority of the job)
for each recipient,
i.e., this value penalizes jobs with large numbers of recipients.
Defaults to 30000.
.ip RefuseLA=\fILA\fP
[X]
When the system load average exceeds
.i LA ,
refuse incoming SMTP connections.
Defaults to 12 multiplied by
the number of processors online on the system
(if that can be determined).
.ip RejectLogInterval=\fItimeout\fP
[no short name]
Log interval when refusing connections for this long
(default: 3h).
.ip RetryFactor=\fIfact\fP
[Z]
The
.i fact or
is added to the priority
every time a job is processed.
Thus,
each time a job is processed,
its priority will be decreased by the indicated value.
In most environments this should be positive,
since hosts that are down are all too often down for a long time.
Defaults to 90000.
.ip SafeFileEnvironment=\fIdir\fP
[no short name]
If this option is set,
.i sendmail
will do a
.i chroot (2)
call into the indicated
.i dir ectory
before doing any file writes.
If the file name specified by the user begins with
.i dir ,
that partial path name will be stripped off before writing,
so (for example)
if the SafeFileEnvironment variable is set to
.q /safe
then aliases of
.q /safe/logs/file
and
.q /logs/file
actually indicate the same file.
Additionally, if this option is set,
.i sendmail
refuses to deliver to symbolic links.
.ip SaveFromLine
[f]
Save
UNIX-style
.q From
lines at the front of headers.
Normally they are assumed redundant
and discarded.
.ip SendMimeErrors
[j]
If set, send error messages in MIME format
(see RFC 2045 and RFC 1344 for details).
If disabled,
.i sendmail
will not return the DSN keyword in response to an EHLO
and will not do Delivery Status Notification processing as described in
RFC 1891.
.ip ServerCertFile
[no short name]
File containing the certificate of the server, i.e., this certificate
is used when sendmail acts as server
(used for STARTTLS).
.ip ServerKeyFile
[no short name]
File containing the private key belonging to the server certificate
(used for STARTTLS).
.ip ServerSSLOptions
A space or comma separated list of SSL related options for the server side.
See
.i SSL_CTX_set_options (3)
for a list;
the available values depend on the OpenSSL version against which
.i sendmail
is compiled.
By default,
.i SSL_OP_ALL
.i -SSL_OP_TLSEXT_PADDING
are used
(if those options are available).
Options can be cleared by preceding them with a minus sign.
It is also possible to specify numerical values, e.g.,
.b -0x0010 .
.ip ServiceSwitchFile=\fIfilename\fP
[no short name]
If your host operating system has a service switch abstraction
(e.g., /etc/nsswitch.conf on Solaris
or /etc/svc.conf on Ultrix and DEC OSF/1)
that service will be consulted and this option is ignored.
Otherwise, this is the name of a file
that provides the list of methods used to implement particular services.
The syntax is a series of lines,
each of which is a sequence of words.
The first word is the service name,
and following words are service types.
The services that
.i sendmail
consults directly are
.q aliases
and
.q hosts.
Service types can be
.q dns ,
.q nis ,
.q nisplus ,
or
.q files
(with the caveat that the appropriate support
must be compiled in
before the service can be referenced).
If ServiceSwitchFile is not specified, it defaults to
/etc/mail/service.switch.
If that file does not exist, the default switch is:
.(b
aliases files
hosts dns nis files
.)b
The default file is
.q /etc/mail/service.switch .
.ip SevenBitInput
[7]
Strip input to seven bits for compatibility with old systems.
This shouldn't be necessary.
.ip SharedMemoryKey
[no short name]
Key to use for shared memory segment;
if not set (or 0), shared memory will not be used.
If set to
-1
.i sendmail
can select a key itself provided that also
.b SharedMemoryKeyFile
is set.
Requires support for shared memory to be compiled into
.i sendmail .
If this option is set,
.i sendmail
can share some data between different instances.
For example, the number of entries in a queue directory
or the available space in a file system.
This allows for more efficient program execution, since only
one process needs to update the data instead of each individual
process gathering the data each time it is required.
.ip SharedMemoryKeyFile
[no short name]
If
.b SharedMemoryKey
is set to
-1
then the automatically selected shared memory key will be stored
in the specified file.
.ip SingleLineFromHeader
[no short name]
If set, From: lines that have embedded newlines are unwrapped
onto one line.
This is to get around a botch in Lotus Notes
that apparently cannot understand legally wrapped RFC 822 headers.
.ip SingleThreadDelivery
[no short name]
If set, a client machine will never try to open two SMTP connections
to a single server machine at the same time,
even in different processes.
That is, if another
.i sendmail
is already talking to some host a new
.i sendmail
will not open another connection.
This property is of mixed value;
although this reduces the load on the other machine,
it can cause mail to be delayed
(for example, if one
.i sendmail
is delivering a huge message, other
.i sendmail s
won't be able to send even small messages).
Also, it requires another file descriptor
(for the lock file)
per connection, so you may have to reduce the
.b ConnectionCacheSize
option to avoid running out of per-process file descriptors.
Requires the
.b HostStatusDirectory
option.
.ip SmtpGreetingMessage=\fImessage\fP
[$e macro]
The message printed when the SMTP server starts up.
Defaults to
.q "$j Sendmail $v ready at $b".
+.ip SMTPUTF8
+Enable runtime support for SMTPUTF8.
.ip SoftBounce
If set, issue temporary errors (4xy) instead of permanent errors (5xy).
This can be useful during testing of a new configuration to avoid
erroneous bouncing of mails.
.ip SSLEngine
Name of SSL engine to use.
The available values depend on the OpenSSL version against which
.i sendmail
is compiled,
see
.(b
openssl engine -v
.)b
for some information.
.ip SSLEnginePath
Path to dynamic library for SSL engine.
This option is only useful if
.i SSLEngine
is set.
If both are set, the engine will be loaded dynamically at runtime
using the concatenation of the path,
a slash "/",
the string "lib",
the value of
.i SSLEngine ,
and the string ".so".
If only
.i SSLEngine
is set then the static version of the engine is used.
.ip StatusFile=\fIfile\fP
[S]
Log summary statistics in the named
.i file .
If no file name is specified, "statistics" is used.
If not set,
no summary statistics are saved.
This file does not grow in size.
It can be printed using the
.i mailstats (8)
program.
.ip SuperSafe
[s]
This option can be set to True, False, Interactive, or PostMilter.
If set to True,
.i sendmail
will be super-safe when running things,
i.e., always instantiate the queue file,
even if you are going to attempt immediate delivery.
.i Sendmail
always instantiates the queue file
before returning control to the client
under any circumstances.
This should really
.i always
be set to True.
The Interactive value has been introduced in 8.12 and can
be used together with
.b DeliveryMode=i .
It skips some synchronization calls which are effectively
doubled in the code execution path for this mode.
If set to PostMilter,
.i sendmail
defers synchronizing the queue file until any milters have
signaled acceptance of the message.
PostMilter is useful only when
.i sendmail
is running as an SMTP server; in all other situations it
acts the same as True.
.ip TLSFallbacktoClear
[no short name]
If set,
.i sendmail
immediately tries an outbound connection again without STARTTLS
after a TLS handshake failure.
Note:
this applies to all connections even if TLS specific requirements are set
(see rulesets
.i tls_rcpt
and
.i tls_client
).
Hence such requirements will cause an error on a retry without STARTTLS.
Therefore they should only trigger a temporary failure so the connection
is later on tried again.
.ip TLSSrvOptions
[no short name]
List of options for SMTP STARTTLS for the server
consisting of single characters
with intervening white space or commas.
The flag ``V'' disables client verification, and hence
it is not possible to use a client certificate for relaying.
The flag ``C'' removes the requirement for the TLS server
to have a cert.
This only works under very specific circumstances
and should only be used if the consequences are understood,
e.g., clients may not work with a server using this.
.ip TempFileMode=\fImode\fP
[F]
The file mode for transcript files, files to which
.i sendmail
delivers directly, files in the
.b HostStatusDirectory ,
and
.b StatusFile .
It is interpreted in octal by default.
Defaults to 0600.
.ip Timeout.\fItype\fP=\|\fItimeout\fP
[r; subsumes old T option as well]
Set timeout values.
For more information,
see section
.\" XREF
4.1.
.ip TimeZoneSpec=\fItzinfo\fP
[t]
Set the local time zone info to
.i tzinfo
\*- for example,
.q PST8PDT .
Actually, if this is not set,
the TZ environment variable is cleared (so the system default is used);
if set but null, the user's TZ variable is used,
and if set and non-null the TZ variable is set to this value.
.ip TrustedUser=\fIuser\fP
[no short name]
The
.i user
parameter may be a user name
(looked up in
.i /etc/passwd )
or a numeric user id.
Trusted user for file ownership and starting the daemon. If set, generated
alias databases and the control socket (if configured) will automatically
be owned by this user.
.ip TryNullMXList
[w]
If this system is the
.q best
(that is, lowest preference)
MX for a given host,
its configuration rules should normally detect this situation
and treat that condition specially
by forwarding the mail to a UUCP feed,
treating it as local,
or whatever.
However, in some cases (such as Internet firewalls)
you may want to try to connect directly to that host
as though it had no MX records at all.
Setting this option causes
.i sendmail
to try this.
The downside is that errors in your configuration
are likely to be diagnosed as
.q "host unknown"
or
.q "message timed out"
instead of something more meaningful.
This option is disrecommended.
.ip UnixFromLine=\fIfromline\fP
[$l macro]
Defines the format used when
.i sendmail
must add a UNIX-style From_ line
(that is, a line beginning
.q From<space>user ).
Defaults to
.q "From $g $d" .
Don't change this unless your system uses a different UNIX mailbox format
(very unlikely).
.ip UnsafeGroupWrites
[no short name]
If set (default),
:include: and .forward files that are group writable are considered
.q unsafe ,
that is,
they cannot reference programs or write directly to files.
World writable :include: and .forward files
are always unsafe.
Note: use
.b DontBlameSendmail
instead; this option is deprecated.
.ip UseCompressedIPv6Addresses
[no short name]
If set, the compressed format of IPv6 addresses,
such as IPV6:::1, will be used,
instead of the uncompressed format,
such as IPv6:0:0:0:0:0:0:0:1.
.ip UseErrorsTo
[l]
If there is an
.q Errors-To:
header, send error messages to the addresses listed there.
They normally go to the envelope sender.
Use of this option causes
.i sendmail
to violate RFC 1123.
This option is disrecommended and deprecated.
.ip UserDatabaseSpec=\fIudbspec\fP
[U]
The user database specification.
.ip Verbose
[v]
Run in verbose mode.
If this is set,
.i sendmail
adjusts options
.b HoldExpensive
(old
.b c )
and
.b DeliveryMode
(old
.b d )
so that all mail is delivered completely
in a single job
so that you can see the entire delivery process.
Option
.b Verbose
should
.i never
be set in the configuration file;
it is intended for command line use only.
Note that the use of option
.b Verbose
can cause authentication information to leak, if you use a
sendmail client to authenticate to a server.
If the authentication mechanism uses plain text passwords
(as with LOGIN or PLAIN),
then the password could be compromised.
To avoid this, do not install sendmail set-user-ID root,
and disable the
.b VERB
SMTP command with a suitable
.b PrivacyOptions
setting.
.ip XscriptFileBufferSize=\fIthreshold\fP
[no short name]
Set the
.i threshold ,
in bytes,
before a memory-based
queue transcript file
becomes disk-based.
The default is 4096 bytes.
.lp
All options can be specified on the command line using the
\-O or \-o flag,
but most will cause
.i sendmail
to relinquish its set-user-ID permissions.
The options that will not cause this are
SevenBitInput [7],
EightBitMode [8],
MinFreeBlocks [b],
CheckpointInterval [C],
DeliveryMode [d],
ErrorMode [e],
IgnoreDots [i],
SendMimeErrors [j],
LogLevel [L],
MeToo [m],
OldStyleHeaders [o],
PrivacyOptions [p],
SuperSafe [s],
Verbose [v],
QueueSortOrder,
MinQueueAge,
DefaultCharSet,
Dial Delay,
NoRecipientAction,
ColonOkInAddr,
MaxQueueRunSize,
SingleLineFromHeader,
and
AllowBogusHELO.
Actually, PrivacyOptions [p] given on the command line
are added to those already specified in the
.i sendmail.cf
file, i.e., they can't be reset.
Also, M (define macro) when defining the r or s macros
is also considered
.q safe .
.sh 2 "P \*- Precedence Definitions"
.pp
Values for the
.q "Precedence:"
field may be defined using the
.b P
control line.
The syntax of this field is:
.(b
\fBP\fP\fIname\fP\fB=\fP\fInum\fP
.)b
When the
.i name
is found in a
.q Precedence:
field,
the message class is set to
.i num .
Higher numbers mean higher precedence.
Numbers less than zero
have the special property
that if an error occurs during processing
the body of the message will not be returned;
this is expected to be used for
.q "bulk"
mail such as through mailing lists.
The default precedence is zero.
For example,
our list of precedences is:
.(b
Pfirst-class=0
Pspecial-delivery=100
Plist=\-30
Pbulk=\-60
Pjunk=\-100
.)b
People writing mailing list exploders
are encouraged to use
.q "Precedence: list" .
Older versions of
.i sendmail
(which discarded all error returns for negative precedences)
didn't recognize this name, giving it a default precedence of zero.
This allows list maintainers to see error returns
on both old and new versions of
.i sendmail .
.sh 2 "V \*- Configuration Version Level"
.pp
To provide compatibility with old configuration files,
the
.b V
line has been added to define some very basic semantics
of the configuration file.
These are not intended to be long term supports;
rather, they describe compatibility features
which will probably be removed in future releases.
.pp
.b N.B.:
these version
.i levels
have nothing
to do with the version
.i number
on the files.
For example,
as of this writing
version 10 config files
(specifically, 8.10)
used version level 9 configurations.
.pp
.q Old
configuration files are defined as version level one.
Version level two files make the following changes:
.np
Host name canonification ($[ ... $])
appends a dot if the name is recognized;
this gives the config file a way of finding out if anything matched.
(Actually, this just initializes the
.q host
map with the
.q \-a.
flag \*- you can reset it to anything you prefer
by declaring the map explicitly.)
.np
Default host name extension is consistent throughout processing;
version level one configurations turned off domain extension
(that is, adding the local domain name)
during certain points in processing.
Version level two configurations are expected to include a trailing dot
to indicate that the name is already canonical.
.np
Local names that are not aliases
are passed through a new distinguished ruleset five;
this can be used to append a local relay.
This behavior can be prevented by resolving the local name
with an initial `@'.
That is, something that resolves to a local mailer and a user name of
.q vikki
will be passed through ruleset five,
but a user name of
.q @vikki
will have the `@' stripped,
will not be passed through ruleset five,
but will otherwise be treated the same as the prior example.
The expectation is that this might be used to implement a policy
where mail sent to
.q vikki
was handled by a central hub,
but mail sent to
.q vikki@localhost
was delivered directly.
.pp
Version level three files
allow # initiated comments on all lines.
Exceptions are backslash escaped # marks
and the $# syntax.
.pp
Version level four configurations
are completely equivalent to level three
for historical reasons.
.pp
Version level five configuration files
change the default definition of
.b $w
to be just the first component of the hostname.
.pp
Version level six configuration files
change many of the local processing options
(such as aliasing and matching the beginning of the address for
`|' characters)
to be mailer flags;
this allows fine-grained control over the special local processing.
Level six configuration files may also use long option names.
The
.b ColonOkInAddr
option (to allow colons in the local-part of addresses)
defaults
.b on
for lower numbered configuration files;
the configuration file requires some additional intelligence
to properly handle the RFC 822 group construct.
.pp
Version level seven configuration files
used new option names to replace old macros
(\c
.b $e
became
.b SmtpGreetingMessage ,
.b $l
became
.b UnixFromLine ,
and
.b $o
became
.b OperatorChars .
Also, prior to version seven,
the
.b F=q
flag (use 250 instead of 252 return value for
.sm "SMTP VRFY"
commands)
was assumed.
.pp
Version level eight configuration files allow
.b $#
on the left hand side of ruleset lines.
.pp
Version level nine configuration files allow
parentheses in rulesets, i.e. they are not treated
as comments and hence removed.
.pp
Version level ten configuration files allow
queue group definitions.
.pp
The
.b V
line may have an optional
.b / \c
.i vendor
to indicate that this configuration file uses modifications
specific to a particular vendor\**.
.(f
\**And of course, vendors are encouraged to add themselves
to the list of recognized vendors by editing the routine
.i setvendor
in
.i conf.c .
Please send e-mail to sendmail@Sendmail.ORG
to register your vendor dialect.
.)f
You may use
.q /Berkeley
to emphasize that this configuration file
uses the Berkeley dialect of
.i sendmail .
.sh 2 "K \*- Key File Declaration"
.pp
Special maps can be defined using the line:
.(b
Kmapname mapclass arguments
.)b
The
.i mapname
is the handle by which this map is referenced in the rewriting rules.
The
.i mapclass
is the name of a type of map;
these are compiled in to
.i sendmail .
The
.i arguments
are interpreted depending on the class;
typically,
there would be a single argument naming the file containing the map.
.pp
Maps are referenced using the syntax:
.(b
$( \fImap\fP \fIkey\fP $@ \fIarguments\fP $: \fIdefault\fP $)
.)b
where either or both of the
.i arguments
or
.i default
portion may be omitted.
The
.i "$@ arguments"
may appear more than once.
The indicated
.i key
and
.i arguments
are passed to the appropriate mapping function.
If it returns a value, it replaces the input.
If it does not return a value and the
.i default
is specified, the
.i default
replaces the input.
Otherwise, the input is unchanged.
.pp
The
.i arguments
are passed to the map for arbitrary use.
Most map classes can interpolate these arguments
into their values using the syntax
.q %\fIn\fP
(where
.i n
is a digit)
to indicate the corresponding
.i argument .
Argument
.q %0
indicates the database key.
For example, the rule
.(b
.ta 1.5i
R$\- ! $+ $: $(uucp $1 $@ $2 $: $2 @ $1 . UUCP $)
.)b
Looks up the UUCP name in a (user defined) UUCP map;
if not found it turns it into
.q \&.UUCP
form.
The database might contain records like:
.(b
decvax %1@%0.DEC.COM
research %1@%0.ATT.COM
.)b
Note that
.i default
clauses never do this mapping.
.pp
The built-in map with both name and class
.q host
is the host name canonicalization lookup.
Thus,
the syntax:
.(b
$(host \fIhostname\fP$)
.)b
is equivalent to:
.(b
$[\fIhostname\fP$]
.)b
.pp
There are many defined classes.
.ip cdb
Database lookups using the cdb(3) library.
.i Sendmail
must be compiled with
.b CDB
defined.
.ip dbm
Database lookups using the ndbm(3) library.
.i Sendmail
must be compiled with
.b NDBM
defined.
.ip btree
Database lookups using the btree interface to the Berkeley DB
library.
.i Sendmail
must be compiled with
.b NEWDB
defined.
.ip hash
Database lookups using the hash interface to the Berkeley DB
library.
.i Sendmail
must be compiled with
.b NEWDB
defined.
.ip nis
NIS lookups.
.i Sendmail
must be compiled with
.b NIS
defined.
.ip nisplus
NIS+ lookups.
.i Sendmail
must be compiled with
.b NISPLUS
defined.
The argument is the name of the table to use for lookups,
and the
.b \-k
and
.b \-v
flags may be used to set the key and value columns respectively.
.ip hesiod
Hesiod lookups.
.i Sendmail
must be compiled with
.b HESIOD
defined.
.ip ldap
LDAP X500 directory lookups.
.i Sendmail
must be compiled with
.b LDAPMAP
defined.
The map supports most of the standard arguments
and most of the command line arguments of the
.i ldapsearch
program.
Note that,
by default,
if a single query matches multiple values,
only the first value will be returned
unless the
.b \-z
(value separator)
map option is set.
Also, the
.b \-1
map flag will treat a multiple value return
as if there were no matches.
.ip netinfo
NeXT NetInfo lookups.
.i Sendmail
must be compiled with
.b NETINFO
defined.
.ip text
Text file lookups.
The format of the text file is defined by the
.b \-k
(key field number),
.b \-v
(value field number),
and
.b \-z
(field delimiter)
options.
.ip ph
PH query map.
Contributed and supported by
Mark Roth, roth@uiuc.edu.
.ip nsd
nsd map for IRIX 6.5 and later.
Contributed and supported by Bob Mende of SGI,
mende@sgi.com.
.ip stab
Internal symbol table lookups.
Used internally for aliasing.
.ip implicit
Sequentially try a list of available map types:
.i hash ,
.i dbm ,
and
.i cdb .
It is the default for alias files if no class is specified.
If is no matching map type is found,
the text version is used for the alias file,
but other maps fail to open.
.ip user
Looks up users using
.i getpwnam (3).
The
.b \-v
flag can be used to specify the name of the field to return
(although this is normally used only to check the existence
of a user).
.ip host
Canonifies host domain names.
Given a host name it calls the name server
to find the canonical name for that host.
.ip bestmx
Returns the best MX record for a host name given as the key.
The current machine is always preferred \*-
that is, if the current machine is one of the hosts listed as a
lowest-preference MX record, then it will be guaranteed to be returned.
This can be used to find out if this machine is the target for an MX record,
and mail can be accepted on that basis.
If the
.b \-z
option is given, then all MX names are returned,
separated by the given delimiter.
Note: the return value is deterministic,
i.e., even if multiple MX records have the same preference,
they will be returned in the same order.
.ip dns
This map requires the option -R to specify the DNS resource record
type to lookup.
The following types are supported:
A, AAAA, AFSDB, CNAME, MX, NS, PTR, SRV, and TXT.
A map lookup will return only one record
unless the
.b \-z
(value separator)
option is set.
Hence for some types, e.g., MX records, the return value might be a random
element of the results due to randomizing in the DNS resolver,
if only one element is returned.
.ip arpa
Returns the ``reverse'' for the given IP (IPv4 or IPv6) address,
i.e., the string for the PTR lookup,
but without trailing
.b ip6.arpa
or
.b in-addr.arpa .
For example, the following configuration lines:
.(b
Karpa arpa
SArpa
R$+ $: $(arpa $1 $)
.)b
work like this in test mode:
.(b
sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> Arpa IPv6:1:2:dead:beef:9876:0:0:1
Arpa input: IPv6 : 1 : 2 : dead : beef : 9876 : 0 : 0 : 1
Arpa returns: 1 . 0 . 0 . 0 . 0 . 0 . 0 . 0 . 0 . 0 . 0 . 0 . 6 . 7 . 8 . 9 . f . e . e . b . d . a . e . d . 2 . 0 . 0 . 0 . 1 . 0 . 0 . 0
> Arpa 1.2.3.4
Arpa input: 1 . 2 . 3 . 4
Arpa returns: 4 . 3 . 2 . 1
.)b
.ip sequence
The arguments on the `K' line are a list of maps;
the resulting map searches the argument maps in order
until it finds a match for the indicated key.
For example, if the key definition is:
.(b
Kmap1 ...
Kmap2 ...
Kseqmap sequence map1 map2
.)b
then a lookup against
.q seqmap
first does a lookup in map1.
If that is found, it returns immediately.
Otherwise, the same key is used for map2.
.ip syslog
the key is logged via
.i syslogd \|(8).
The lookup returns the empty string.
.ip switch
Much like the
.q sequence
map except that the order of maps is determined by the service switch.
The argument is the name of the service to be looked up;
the values from the service switch are appended to the map name
to create new map names.
For example, consider the key definition:
.(b
Kali switch aliases
.)b
together with the service switch entry:
.(b
aliases nis files
.)b
This causes a query against the map
.q ali
to search maps named
.q ali.nis
and
.q ali.files
in that order.
.ip dequote
Strip double quotes (") from a name.
It does not strip backslashes,
and will not strip quotes if the resulting string
would contain unscannable syntax
(that is, basic errors like unbalanced angle brackets;
more sophisticated errors such as unknown hosts are not checked).
The intent is for use when trying to accept mail from systems such as
DECnet
that routinely quote odd syntax such as
.(b
"49ers::ubell"
.)b
A typical usage is probably something like:
.(b
Kdequote dequote
\&...
R$\- $: $(dequote $1 $)
R$\- $+ $: $>3 $1 $2
.)b
Care must be taken to prevent unexpected results;
for example,
.(b
"|someprogram < input > output"
.)b
will have quotes stripped,
but the result is probably not what you had in mind.
Fortunately these cases are rare.
.ip regex
The map definition on the
.b K
line contains a regular expression.
Any key input is compared to that expression using the
POSIX regular expressions routines regcomp(), regerr(), and regexec().
Refer to the documentation for those routines for more information
about the regular expression matching.
No rewriting of the key is done if the
.b \-m
flag is used. Without it, the key is discarded or if
.b \-s
if used, it is substituted by the substring matches, delimited by
.b $|
-or the string specified with the the
+or the string specified with the
.b \-d
option.
The options available for the map are
.(b
.ta 4n
-n not
-f case sensitive
-b basic regular expressions (default is extended)
-s substring match
-d set the delimiter string used for -s
-a append string to key
-m match only, do not replace/discard value
-D perform no lookup in deferred delivery mode.
.)b
The
.b \-s
option can include an optional parameter which can be used
to select the substrings in the result of the lookup.
For example,
.(b
-s1,3,4
.)b
The delimiter string specified via the
.b \-d
option is the sequence of characters after
.b d
ending at the first space.
Hence it isn't possible to specify a space as delimiter,
so if the option is immediately followed by a space
the delimiter string is empty,
which means the substrings are joined.
Notes: to match a
.b $
in a string,
\\$$
must be used.
If the pattern contains spaces,
they must be replaced with the blank substitution character,
unless it is space itself.
.ip program
The arguments on the
.b K
line are the pathname to a program and any initial parameters to be passed.
When the map is called,
the key is added to the initial parameters
and the program is invoked
as the default user/group id.
The first line of standard output is returned as the value of the lookup.
This has many potential security problems,
and has terrible performance;
it should be used only when absolutely necessary.
.ip macro
Set or clear a macro value.
To set a macro,
pass the value as the first argument in the map lookup.
To clear a macro,
do not pass an argument in the map lookup.
The map always returns the empty string.
Example of typical usage include:
.(b
Kstorage macro
\&...
# set macro ${MyMacro} to the ruleset match
R$+ $: $(storage {MyMacro} $@ $1 $) $1
# set macro ${MyMacro} to an empty string
R$* $: $(storage {MyMacro} $@ $) $1
# clear macro ${MyMacro}
R$\- $: $(storage {MyMacro} $) $1
.)b
.ip arith
Perform simple arithmetic operations.
The operation is given as key, currently
+, -, *, /, %,
|, & (bitwise OR, AND),
l (for less than), =,
and r (for random) are supported.
The two operands are given as arguments.
The lookup returns the result of the computation,
i.e.,
.sm TRUE
or
.sm FALSE
for comparisons, integer values otherwise.
The r operator returns a pseudo-random number whose value
lies between the first and second operand
(which requires that the first operand is smaller than the second).
All options which are possible for maps are ignored.
A simple example is:
.(b
Kcomp arith
\&...
Scheck_etrn
R$* $: $(comp l $@ $&{load_avg} $@ 7 $) $1
RFALSE $# error \&...
.)b
.ip socket
The socket map uses a simple request/reply protocol over TCP or UNIX domain
sockets to query an external server.
Both requests and replies are text based and encoded as netstrings,
i.e., a string "hello there" becomes:
.(b
11:hello there,
.)b
Note: neither requests nor replies end with CRLF.
The request consists of the database map name and the lookup key separated
by a space character:
.(b
<mapname> ' ' <key>
.)b
The server responds with a status indicator and the result (if any):
.(b
<status> ' ' <result>
.)b
The status indicator specifies the result of the lookup operation itself
and is one of the following upper case words:
.(b
.ta 9n
OK the key was found, result contains the looked up value
NOTFOUND the key was not found, the result is empty
TEMP a temporary failure occurred
TIMEOUT a timeout occurred on the server side
PERM a permanent failure occurred
.)b
In case of errors (status TEMP, TIMEOUT or PERM) the result field may
contain an explanatory message.
However, the explanatory message is not used any further by
.i sendmail .
Example replies:
.(b
31:OK resolved.address@example.com,
.)b
.(b
56:OK error:550 5.7.1 User does not accept mail from sender,
.)b
in case of successful lookups, or:
.(b
8:NOTFOUND,
.)b
in case the key was not found, or:
.(b
55:TEMP this text explains that we had a temporary failure,
.)b
in case of a temporary map lookup failure.
The socket map uses the same syntax as milters
(see Section "X \*- Mail Filter (Milter) Definitions")
to specify the remote endpoint, e.g.,
.(b
Ksocket mySocketMap inet:12345@127.0.0.1
.)b
If multiple socket maps define the same remote endpoint, they will share
a single connection to this endpoint.
.pp
Most of these accept as arguments the same optional flags
and a filename
(or a mapname for NIS;
the filename is the root of the database path,
so that
.q .db
or some other extension appropriate for the database type
will be added to get the actual database name).
Known flags are:
.ip "\-o"
Indicates that this map is optional \*- that is,
if it cannot be opened,
no error is produced,
and
.i sendmail
will behave as if the map existed but was empty.
.ip "\-N, \-O"
If neither
.b \-N
or
.b \-O
are specified,
.i sendmail
uses an adaptive algorithm to decide whether or not to look for null bytes
on the end of keys.
It starts by trying both;
if it finds any key with a null byte it never tries again without a null byte
and vice versa.
If
.b \-N
is specified it never tries without a null byte and
if
.b \-O
is specified it never tries with a null byte.
Setting one of
these can speed matches but are never necessary.
If both
.b \-N
and
.b \-O
are specified,
.i sendmail
will never try any matches at all \(em
that is, everything will appear to fail.
.ip "\-a\fIx\fP"
Append the string
.i x
on successful matches.
For example, the default
.i host
map appends a dot on successful matches.
.ip "\-T\fIx\fP"
Append the string
.i x
on temporary failures.
For example,
.i x
would be appended if a DNS lookup returned
.q "server failed"
or an NIS lookup could not locate a server.
See also the
.b \-t
flag.
.ip "\-f"
Do not fold upper to lower case before looking up the key.
.ip "\-m"
Match only (without replacing the value).
If you only care about the existence of a key and not the value
(as you might when searching the NIS map
.q hosts.byname
for example),
this flag prevents the map from substituting the value.
However,
The \-a argument is still appended on a match,
and the default is still taken if the match fails.
.ip "\-k\fIkeycol\fP"
The key column name (for NIS+) or number
(for text lookups).
For LDAP maps this is an LDAP filter string
in which %s is replaced with the literal contents of the lookup key
and %0 is replaced with the LDAP escaped contents of the lookup key
according to RFC 2254.
If the flag
.b \-K
is used, then %1 through %9 are replaced with the LDAP escaped contents
of the arguments specified in the map lookup.
.ip "\-v\fIvalcol\fP"
The value column name (for NIS+) or number
(for text lookups).
For LDAP maps this is the name of one or more
attributes to be returned;
multiple attributes can be separated by commas.
If not specified, all attributes found in the match
will be returned.
The attributes listed can also include a type and one or more
objectClass values for matching as described in the LDAP section.
.ip "\-z\fIdelim\fP"
The column delimiter (for text lookups).
It can be a single character or one of the special strings
.q \|\en
or
.q \|\et
to indicate newline or tab respectively.
If omitted entirely,
the column separator is any sequence of white space.
For LDAP and some other maps this is the separator character
to combine multiple values
into a single return string.
If not set,
the LDAP lookup will only return the first match found.
For DNS maps this is the separator character at which
the result of a query is cut off if is too long.
.ip "\-t"
Normally, when a map attempts to do a lookup
and the server fails
(e.g.,
.i sendmail
couldn't contact any name server;
this is
.i not
the same as an entry not being found in the map),
the message being processed is queued for future processing.
The
.b \-t
flag turns off this behavior,
letting the temporary failure (server down)
act as though it were a permanent failure (entry not found).
It is particularly useful for DNS lookups,
where someone else's misconfigured name server can cause problems
on your machine.
However, care must be taken to ensure that you don't bounce mail
that would be resolved correctly if you tried again.
A common strategy is to forward such mail
to another, possibly better connected, mail server.
.ip "\-D"
Perform no lookup in deferred delivery mode.
This flag is set by default for the
.i host
map.
.ip "\-S\fIspacesub\fP
The character to use to replace space characters
after a successful map lookup (esp. useful for regex
and syslog maps).
.ip "\-s\fIspacesub\fP
For the dequote map only,
the character to use to replace space characters
after a successful dequote.
.ip "\-q"
Don't dequote the key before lookup.
.ip "\-L\fIlevel\fP
For the syslog map only, it specifies the level
to use for the syslog call.
.ip "\-A"
When rebuilding an alias file,
the
.b \-A
flag causes duplicate entries in the text version
to be merged.
For example, two entries:
.(b
list: user1, user2
list: user3
.)b
would be treated as though it were the single entry
.(b
list: user1, user2, user3
.)b
in the presence of the
.b \-A
flag.
.pp
Some additional flags are available for the host and dns maps:
.ip "\-d"
delay: specify the resolver's retransmission time interval (in seconds).
.ip "\-r"
retry: specify the number of times to retransmit a resolver query.
.pp
The dns map has another flag:
.ip "\-B"
basedomain: specify a domain that is always appended to queries.
.pp
Socket maps have an optional flag:
.ip "\-d"
timeout: specify the timeout (in seconds) for communication
with the socket map server.
.pp
The following additional flags are present in the ldap map only:
.ip "\-c\fItimeout\fP"
Set the LDAP network timeout.
sendmail must be compiled with
.b \-DLDAP_OPT_NETWORK_TIMEOUT
to use this flag.
.ip "\-R"
Do not auto chase referrals. sendmail must be compiled with
.b \-DLDAP_REFERRALS
to use this flag.
.ip "\-n"
Retrieve attribute names only.
.ip "\-V\fIsep\fP"
Retrieve both attributes name and value(s),
separated by
.i sep .
.ip "\-r\fIderef\fP"
Set the alias dereference option to one of never, always, search, or find.
.ip "\-s\fIscope\fP"
Set search scope to one of base, one (one level), or sub (subtree).
.ip "\-h\fIhost\fP"
LDAP server hostname.
Some LDAP libraries allow you to specify multiple, space-separated hosts for
redundancy.
In addition, each of the hosts listed can be followed by a colon and a port
number to override the default LDAP port.
.ip "\-p\fIport\fP"
LDAP service port.
.ip "\-H \fILDAPURI\fP"
Use the specified LDAP URI instead of specifying the hostname and port
-separately with the the
+separately with the
.b \-h
and
.b \-p
options shown above.
For example,
.(b
-h server.example.com -p 389 -b dc=example,dc=com
.)b
is equivalent to
.(b
-H ldap://server.example.com:389 -b dc=example,dc=com
.)b
If the LDAP library supports it,
the LDAP URI format however can also request LDAP over SSL by using
.b ldaps://
instead of
.b ldap:// .
For example:
.(b
O LDAPDefaultSpec=-H ldaps://ldap.example.com -b dc=example,dc=com
.)b
Similarly, if the LDAP library supports it,
It can also be used to specify a UNIX domain socket using
.b ldapi:// :
.(b
O LDAPDefaultSpec=-H ldapi://socketfile -b dc=example,dc=com
.)b
.ip "\-b\fIbase\fP"
LDAP search base.
.ip "\-l\fItimelimit\fP"
Time limit for LDAP queries.
.ip "\-Z\fIsizelimit\fP"
Size (number of matches) limit for LDAP or DNS queries.
.ip "\-d\fIdistinguished_name\fP"
The distinguished name to use to login to the LDAP server.
.ip "\-M\fImethod\fP"
The method to authenticate to the LDAP server.
Should be one of
.b LDAP_AUTH_NONE ,
.b LDAP_AUTH_SIMPLE ,
or
.b LDAP_AUTH_KRBV4 .
The leading
.b LDAP_AUTH_
can be omitted and the value is case-insensitive.
.ip "\-P\fIpasswordfile\fP"
The file containing the secret key for the
.b LDAP_AUTH_SIMPLE
authentication method
or the name of the Kerberos ticket file for
.b LDAP_AUTH_KRBV4 .
.ip "\-1"
Force LDAP searches to only succeed if a single match is found.
If multiple values are found,
the search is treated as if no match was found.
.ip "\-w\fIversion\fP"
Set the LDAP API/protocol version to use.
The default depends on the LDAP client libraries in use.
For example,
.b "\-w 3"
will cause
.i sendmail
to use LDAPv3 when communicating with the LDAP server.
.ip "\-K"
Treat the LDAP search key as multi-argument and
replace %1 through %9 in the key with
the LDAP escaped contents of the lookup arguments specified in the map lookup.
.pp
The
.i dbm
map appends the strings
.q \&.pag
and
.q \&.dir
to the given filename;
the
.i hash
and
.i btree
maps append
.q \&.db .
For example, the map specification
.(b
Kuucp dbm \-o \-N /etc/mail/uucpmap
.)b
specifies an optional map named
.q uucp
of class
.q dbm ;
it always has null bytes at the end of every string,
and the data is located in
/etc/mail/uucpmap.{dir,pag}.
.pp
The program
.i makemap (8)
can be used to build database-oriented maps.
It takes at least the following flags
(for a complete list see its man page):
.ip \-f
Do not fold upper to lower case in the map.
.ip \-N
Include null bytes in keys.
.ip \-o
Append to an existing (old) file.
.ip \-r
Allow replacement of existing keys;
normally, re-inserting an existing key is an error.
.ip \-v
Print what is happening.
.lp
The
.i sendmail
daemon does not have to be restarted to read the new maps
as long as you change them in place;
file locking is used so that the maps won't be read
while they are being updated.
.pp
New classes can be added in the routine
.b setupmaps
in file
.b conf.c .
.sh 2 "Q \*- Queue Group Declaration"
.pp
In addition to the option
.i QueueDirectory,
queue groups can be declared that define a (group of) queue directories
under a common name.
The syntax is as follows:
.(b F
.b Q \c
.i name
{, \c
.i field =\c
.i value \|}+
.)b
where
.i name
is the symbolic name of the queue group under which
it can be referenced in various places
and the
.q field=value
pairs define attributes of the queue group.
The name must only consist of alphanumeric characters.
Fields are:
.ip Flags
Flags for this queue group.
.ip Nice
The nice(2) increment for the queue group.
This value must be greater or equal zero.
.ip Interval
The time between two queue runs.
.ip Path
The queue directory of the group (required).
.ip Runners
The number of parallel runners processing the queue.
Note that
.b F=f
must be set if this value is greater than one.
.ip Jobs
The maximum number of jobs (messages delivered) per queue run.
.ip recipients
The maximum number of recipients per envelope.
Envelopes with more than this number of recipients will be split
into multiple envelopes in the same queue directory.
The default value 0 means no limit.
.lp
Only the first character of the field name is checked.
.pp
By default, a queue group named
.i mqueue
is defined that uses the value of the
.i QueueDirectory
option as path.
Notice: all paths that are used for queue groups must
be subdirectories of
.i QueueDirectory .
Since they can be symbolic links, this isn't a real restriction,
If
.i QueueDirectory
uses a wildcard, then the directory one level up is considered
the ``base'' directory which all other queue directories must share.
Please make sure that the queue directories do not overlap,
e.g., do not specify
.(b
O QueueDirectory=/var/spool/mqueue/*
Qone, P=/var/spool/mqueue/dir1
Qtwo, P=/var/spool/mqueue/dir2
.)b
because this also includes
.q dir1
and
.q dir2
in the default queue group.
However,
.(b
O QueueDirectory=/var/spool/mqueue/main*
Qone, P=/var/spool/mqueue/dir
Qtwo, P=/var/spool/mqueue/other*
.)b
is a valid queue group specification.
.pp
Options listed in the ``Flags'' field can be used to modify
the behavior of a queue group.
The ``f'' flag must be set if multiple queue runners are
supposed to work on the entries in a queue group.
Otherwise
.i sendmail
will work on the entries strictly sequentially.
.pp
The ``Interval'' field sets the time between queue runs.
If no queue group specific interval is set, then the parameter of the
.b -q
option from the command line is used.
.pp
To control the overall number of concurrently active queue runners
the option
.b MaxQueueChildren
can be set.
This limits the number of processes used for running the queues to
.b MaxQueueChildren ,
though at any one time fewer processes may be active
as a result of queue options, completed queue runs, system load, etc.
.pp
The maximum number of queue runners for an individual queue group can be
controlled via the
.b Runners
option.
If set to 0, entries in the queue will not be processed, which
is useful to ``quarantine'' queue files.
The number of runners per queue group may also be set with the option
.b MaxRunnersPerQueue ,
which applies to queue groups that have no individual limit.
That is, the default value for
.b Runners
is
.b MaxRunnersPerQueue
if set, otherwise 1.
.pp
The field Jobs describes the maximum number of jobs
(messages delivered) per queue run, which is the queue group specific
value of
.b MaxQueueRunSize .
.pp
Notice: queue groups should be declared after all queue related options
have been set because queue groups take their defaults from those options.
If an option is set after a queue group declaration, the values of
options in the queue group are set to the defaults of
.i sendmail
unless explicitly set in the declaration.
.pp
Each envelope is assigned to a queue group based on the algorithm
described in section
``Queue Groups and Queue Directories''.
.sh 2 "X \*- Mail Filter (Milter) Definitions"
.pp
The
.i sendmail
Mail Filter API (Milter) is designed to allow third-party programs access
to mail messages as they are being processed in order to filter
meta-information and content.
They are declared in the configuration file as:
.(b F
.b X \c
.i name
{, \c
.i field =\c
.i value \|}*
.)b
where
.i name
is the name of the filter
(used internally only)
and the
.q field=name
pairs define attributes of the filter.
Also see the documentation for the
.b InputMailFilters
option for more information.
.pp
Fields are:
.(b
.ta 1i
Socket The socket specification
Flags Special flags for this filter
Timeouts Timeouts for this filter
.)b
Only the first character of the field name is checked
(it's case-sensitive).
.pp
The socket specification is one of the following forms:
.(b F
.b S= \c
.b inet \c
.b :
.i port
.b @
.i host
.)b
.(b F
.b S= \c
.b inet6 \c
.b :
.i port
.b @
.i host
.)b
.(b F
.b S= \c
.b local \c
.b :
.i path
.)b
The first two describe an IPv4 or IPv6 socket listening on a certain
.i port
at a given
.i host
or IP address.
The final form describes a named socket on the filesystem at the given
.i path .
.pp
The following flags may be set in the filter description.
.nr ii 4n
.ip R
Reject connection if filter unavailable.
.ip T
Temporary fail connection if filter unavailable.
.pp
If neither F=R nor F=T is specified, the message is passed through
.i sendmail
in case of filter errors as if the failing filters were not present.
.pp
The timeouts can be set using the four fields inside of the
.b T=
equate:
.nr ii 4n
.ip C
Timeout for connecting to a filter.
If set to 0, the system's
.i connect()
timeout will be used.
.ip S
Timeout for sending information from the MTA to a filter.
.ip R
Timeout for reading reply from the filter.
.ip E
Overall timeout between sending end-of-message to filter and waiting for
the final acknowledgment.
.pp
Note the separator between each timeout field is a
.b ';' .
The default values (if not set) are:
.b T=C:5m;S:10s;R:10s;E:5m
where
.b s
is seconds and
.b m
is minutes.
.pp
Examples:
.(b
Xfilter1, S=local:/var/run/f1.sock, F=R
Xfilter2, S=inet6:999@localhost, F=T, T=S:1s;R:1s;E:5m
Xfilter3, S=inet:3333@localhost, T=C:2m
.)b
.sh 2 "The User Database"
.pp
The user database is deprecated in favor of ``virtusertable''
and ``genericstable'' as explained in the file
.b cf/README .
If you have a version of
.i sendmail
with the user database package
compiled in,
the handling of sender and recipient addresses
is modified.
.pp
The location of this database is controlled with the
.b UserDatabaseSpec
option.
.sh 3 "Structure of the user database"
.pp
The database is a sorted (BTree-based) structure.
User records are stored with the key:
.(b
\fIuser-name\fP\fB:\fP\fIfield-name\fP
.)b
The sorted database format ensures that user records are clustered together.
Meta-information is always stored with a leading colon.
.pp
Field names define both the syntax and semantics of the value.
Defined fields include:
.nr ii 1i
.ip maildrop
The delivery address for this user.
There may be multiple values of this record.
In particular,
mailing lists will have one
.i maildrop
record for each user on the list.
.ip "mailname"
The outgoing mailname for this user.
For each outgoing name,
there should be an appropriate
.i maildrop
record for that name to allow return mail.
See also
.i :default:mailname .
.ip mailsender
Changes any mail sent to this address to have the indicated envelope sender.
This is intended for mailing lists,
and will normally be the name of an appropriate -request address.
It is very similar to the owner-\c
.i list
syntax in the alias file.
.ip fullname
The full name of the user.
.ip office-address
The office address for this user.
.ip office-phone
The office phone number for this user.
.ip office-fax
The office FAX number for this user.
.ip home-address
The home address for this user.
.ip home-phone
The home phone number for this user.
.ip home-fax
The home FAX number for this user.
.ip project
A (short) description of the project this person is affiliated with.
In the University this is often just the name of their graduate advisor.
.ip plan
A pointer to a file from which plan information can be gathered.
.pp
As of this writing,
only a few of these fields are actually being used by
.i sendmail :
.i maildrop
and
.i mailname .
A
.i finger
program that uses the other fields is planned.
.sh 3 "User database semantics"
.pp
When the rewriting rules submit an address to the local mailer,
the user name is passed through the alias file.
If no alias is found (or if the alias points back to the same address),
the name (with
.q :maildrop
appended)
is then used as a key in the user database.
If no match occurs (or if the maildrop points at the same address),
forwarding is tried.
.pp
If the first token of the user name returned by ruleset 0
is an
.q @
sign, the user database lookup is skipped.
The intent is that the user database will act as a set of defaults
for a cluster (in our case, the Computer Science Division);
mail sent to a specific machine should ignore these defaults.
.pp
When mail is sent,
the name of the sending user is looked up in the database.
If that user has a
.q mailname
record,
the value of that record is used as their outgoing name.
For example, I might have a record:
.(b
eric:mailname Eric.Allman@CS.Berkeley.EDU
.)b
This would cause my outgoing mail to be sent as Eric.Allman.
.pp
If a
.q maildrop
is found for the user,
but no corresponding
.q mailname
record exists,
the record
.q :default:mailname
is consulted.
If present, this is the name of a host to override the local host.
For example, in our case we would set it to
.q CS.Berkeley.EDU .
The effect is that anyone known in the database
gets their outgoing mail stamped as
.q user@CS.Berkeley.EDU ,
but people not listed in the database use the local hostname.
.sh 3 "Creating the database\**"
.(f
\**These instructions are known to be incomplete.
Other features are available which provide similar functionality,
e.g., virtual hosting and mapping local addresses into a
generic form as explained in cf/README.
.)f
.pp
The user database is built from a text file
using the
.i makemap
utility
(in the distribution in the makemap subdirectory).
The text file is a series of lines corresponding to userdb records;
each line has a key and a value separated by white space.
The key is always in the format described above \*-
for example:
.(b
eric:maildrop
.)b
This file is normally installed in a system directory;
for example, it might be called
.i /etc/mail/userdb .
To make the database version of the map, run the program:
.(b
makemap btree /etc/mail/userdb < /etc/mail/userdb
.)b
Then create a config file that uses this.
For example, using the V8 M4 configuration, include the
following line in your .mc file:
.(b
define(\`confUSERDB_SPEC\', /etc/mail/userdb)
.)b
.sh 1 "OTHER CONFIGURATION"
.pp
There are some configuration changes that can be made by
recompiling
.i sendmail .
This section describes what changes can be made
and what has to be modified to make them.
In most cases this should be unnecessary
unless you are porting
.i sendmail
to a new environment.
.sh 2 "Parameters in devtools/OS/$oscf"
.pp
These parameters are intended to describe the compilation environment,
not site policy,
and should normally be defined in the operating system
configuration file.
.b "This section needs a complete rewrite."
.ip NDBM
If set,
the new version of the DBM library
that allows multiple databases will be used.
If neither CDB, NDBM, nor NEWDB are set,
a much less efficient method of alias lookup is used.
.ip CWDB
If set, use the cdb (tinycdb) package.
.ip NEWDB
If set, use the new database package from Berkeley (from 4.4BSD).
This package is substantially faster than DBM or NDBM.
If NEWDB and NDBM are both set,
.i sendmail
will read DBM files,
but will create and use NEWDB files.
.ip NIS
Include support for NIS.
If set together with
.i both
NEWDB and NDBM,
.i sendmail
will create both DBM and NEWDB files if and only if
an alias file includes the substring
.q /yp/
in the name.
This is intended for compatibility with Sun Microsystems'
.i mkalias
program used on YP masters.
.ip NISPLUS
Compile in support for NIS+.
.ip NETINFO
Compile in support for NetInfo (NeXT stations).
.ip LDAPMAP
Compile in support for LDAP X500 queries.
Requires libldap and liblber
from the Umich LDAP 3.2 or 3.3 release
or equivalent libraries for other LDAP libraries
such as OpenLDAP.
.ip HESIOD
Compile in support for Hesiod.
.ip MAP_NSD
Compile in support for IRIX NSD lookups.
.ip MAP_REGEX
Compile in support for regular expression matching.
.ip DNSMAP
Compile in support for DNS map lookups in the
.i sendmail.cf
file.
.ip PH_MAP
Compile in support for ph lookups.
.ip SASL
Compile in support for SASL,
a required component for SMTP Authentication support.
.ip STARTTLS
Compile in support for STARTTLS.
.ip EGD
Compile in support for the "Entropy Gathering Daemon"
to provide better random data for TLS.
.ip TCPWRAPPERS
Compile in support for TCP Wrappers.
.ip _PATH_SENDMAILCF
The pathname of the sendmail.cf file.
.ip _PATH_SENDMAILPID
The pathname of the sendmail.pid file.
.ip SM_CONF_SHM
Compile in support for shared memory, see section about
"/var/spool/mqueue".
.ip MILTER
Compile in support for contacting external mail filters built with the
Milter API.
.pp
There are also several compilation flags to indicate the environment
such as
.q _AIX3
and
.q _SCO_unix_ .
See the sendmail/README
file for the latest scoop on these flags.
.sh 3 "For Future Releases"
.pp
.i sendmail
often contains compile time options
.i "For Future Releases"
(prefix _FFR_)
which might be enabled in a subsequent version
or might simply be removed as they turned out not to be really useful.
These features are usually not documented but if they are,
then the required (FFR) compile
time options are listed here for rulesets and macros,
and in
.i cf/README
for mc/cf options.
FFR compile times options must be enabled when the sendmail binary
is built from source.
Enabled FFRs in a binary can be listed with
.(b
sendmail -d0.13 < /dev/null | grep FFR
.)b
.sh 2 "Parameters in sendmail/conf.h"
.pp
Parameters and compilation options
are defined in conf.h.
Most of these need not normally be tweaked;
common parameters are all in sendmail.cf.
However, the sizes of certain primitive vectors, etc.,
are included in this file.
The numbers following the parameters
are their default value.
.pp
This document is not the best source of information
for compilation flags in conf.h \(em
see sendmail/README or sendmail/conf.h itself.
.nr ii 1.2i
.ip "MAXLINE [2048]"
The maximum line length of any input line.
If message lines exceed this length
they will still be processed correctly;
however, header lines,
configuration file lines,
alias lines,
etc.,
must fit within this limit.
.ip "MAXNAME [256]"
The maximum length of any name,
such as a host or a user name.
.ip "MAXPV [256]"
The maximum number of parameters to any mailer.
This limits the number of recipients that may be passed in one transaction.
It can be set to any arbitrary number above about 10,
since
.i sendmail
will break up a delivery into smaller batches as needed.
A higher number may reduce load on your system, however.
.ip "MAXQUEUEGROUPS [50]"
The maximum number of queue groups.
.ip "MAXATOM [1000]"
The maximum number of atoms
(tokens)
in a single address.
For example,
the address
.q "eric@CS.Berkeley.EDU"
is seven atoms.
.ip "MAXMAILERS [25]"
The maximum number of mailers that may be defined
in the configuration file.
This value is defined in include/sendmail/sendmail.h.
.ip "MAXRWSETS [200]"
The maximum number of rewriting sets
that may be defined.
The first half of these are reserved for numeric specification
(e.g., ``S92''),
while the upper half are reserved for auto-numbering
(e.g., ``Sfoo'').
Thus, with a value of 200 an attempt to use ``S99'' will succeed,
but ``S100'' will fail.
.ip "MAXPRIORITIES [25]"
The maximum number of values for the
.q Precedence:
field that may be defined
(using the
.b P
line in sendmail.cf).
.ip "MAXUSERENVIRON [100]"
The maximum number of items in the user environment
that will be passed to subordinate mailers.
.ip "MAXMXHOSTS [100]"
The maximum number of MX records we will accept for any single host.
.ip "MAXMAPSTACK [12]"
The maximum number of maps that may be "stacked" in a
.b sequence
class map.
.ip "MAXMIMEARGS [20]"
The maximum number of arguments in a MIME Content-Type: header;
additional arguments will be ignored.
.ip "MAXMIMENESTING [20]"
The maximum depth to which MIME messages may be nested
(that is, nested Message or Multipart documents;
this does not limit the number of components in a single Multipart document).
.ip "MAXDAEMONS [10]"
The maximum number of sockets sendmail will open for accepting connections
on different ports.
.ip "MAXMACNAMELEN [25]"
The maximum length of a macro name.
.lp
A number of other compilation options exist.
These specify whether or not specific code should be compiled in.
Ones marked with \(dg
are 0/1 valued.
.nr ii 1.2i
.ip NETINET\(dg
If set,
support for Internet protocol networking is compiled in.
Previous versions of
.i sendmail
referred to this as
.sm DAEMON ;
this old usage is now incorrect.
Defaults on;
turn it off in the Makefile
if your system doesn't support the Internet protocols.
.ip NETINET6\(dg
If set,
support for IPv6 networking is compiled in.
It must be separately enabled by adding
.b DaemonPortOptions
settings.
.ip NETISO\(dg
If set,
support for ISO protocol networking is compiled in
(it may be appropriate to #define this in the Makefile instead of conf.h).
.ip NETUNIX\(dg
If set,
support for UNIX domain sockets is compiled in.
This is used for control socket support.
.ip LOG
If set,
the
.i syslog
routine in use at some sites is used.
This makes an informational log record
for each message processed,
and makes a higher priority log record
for internal system errors.
.b "STRONGLY RECOMMENDED"
\(em if you want no logging, turn it off in the configuration file.
.ip MATCHGECOS\(dg
Compile in the code to do ``fuzzy matching'' on the GECOS field
in /etc/passwd.
This also requires that the
.b MatchGECOS
option be turned on.
.ip NAMED_BIND\(dg
Compile in code to use the
Berkeley Internet Name Domain (BIND) server
to resolve TCP/IP host names.
.ip NOTUNIX
If you are using a non-UNIX mail format,
you can set this flag to turn off special processing
of UNIX-style
.q "From "
lines.
.ip USERDB\(dg
Include the
.b experimental
Berkeley user information database package.
This adds a new level of local name expansion
between aliasing and forwarding.
It also uses the NEWDB package.
This may change in future releases.
.lp
The following options are normally turned on
in per-operating-system clauses in conf.h.
.ip IDENTPROTO\(dg
Compile in the IDENT protocol as defined in RFC 1413.
This defaults on for all systems except Ultrix,
which apparently has the interesting
.q feature
that when it receives a
.q "host unreachable"
message it closes all open connections to that host.
Since some firewall gateways send this error code
when you access an unauthorized port (such as 113, used by IDENT),
Ultrix cannot receive email from such hosts.
.ip SYSTEM5
Set all of the compilation parameters appropriate for System V.
.ip HASFLOCK\(dg
Use Berkeley-style
.b flock
instead of System V
.b lockf
to do file locking.
Due to the highly unusual semantics of locks
across forks in
.b lockf ,
this should always be used if at all possible.
.ip HASINITGROUPS
Set this if your system has the
.i initgroups()
call
(if you have multiple group support).
This is the default if SYSTEM5 is
.i not
defined or if you are on HPUX.
.ip HASUNAME
Set this if you have the
.i uname (2)
system call (or corresponding library routine).
Set by default if
SYSTEM5
is set.
.ip HASGETDTABLESIZE
Set this if you have the
.i getdtablesize (2)
system call.
.ip HASWAITPID
Set this if you have the
.i haswaitpid (2)
system call.
.ip FAST_PID_RECYCLE
Set this if your system can possibly
reuse the same pid in the same second of time.
.ip SFS_TYPE
The mechanism that can be used to get file system capacity information.
The values can be one of
SFS_USTAT (use the ustat(2) syscall),
SFS_4ARGS (use the four argument statfs(2) syscall),
SFS_VFS (use the two argument statfs(2) syscall including <sys/vfs.h>),
SFS_MOUNT (use the two argument statfs(2) syscall including <sys/mount.h>),
SFS_STATFS (use the two argument statfs(2) syscall including <sys/statfs.h>),
SFS_STATVFS (use the two argument statfs(2) syscall including <sys/statvfs.h>),
or
SFS_NONE (no way to get this information).
.ip LA_TYPE
The load average type.
Details are described below.
.lp
The are several built-in ways of computing the load average.
.i Sendmail
tries to auto-configure them based on imperfect guesses;
you can select one using the
.i cc
option
.b \-DLA_TYPE= \c
.i type ,
where
.i type
is:
.ip LA_INT
The kernel stores the load average in the kernel as an array of long integers.
The actual values are scaled by a factor FSCALE
(default 256).
.ip LA_SHORT
The kernel stores the load average in the kernel as an array of short integers.
The actual values are scaled by a factor FSCALE
(default 256).
.ip LA_FLOAT
The kernel stores the load average in the kernel as an array of
double precision floats.
.ip LA_MACH
Use MACH-style load averages.
.ip LA_SUBR
Call the
.i getloadavg
routine to get the load average as an array of doubles.
.ip LA_ZERO
Always return zero as the load average.
This is the fallback case.
.lp
If type
.sm LA_INT ,
.sm LA_SHORT ,
or
.sm LA_FLOAT
is specified,
you may also need to specify
.sm _PATH_UNIX
(the path to your system binary)
and
.sm LA_AVENRUN
(the name of the variable containing the load average in the kernel;
usually
.q _avenrun
or
.q avenrun ).
.sh 2 "Configuration in sendmail/conf.c"
.pp
The following changes can be made in conf.c.
.sh 3 "Built-in Header Semantics"
.pp
Not all header semantics are defined in the configuration file.
Header lines that should only be included by certain mailers
(as well as other more obscure semantics)
must be specified in the
.i HdrInfo
table in
.i conf.c .
This table contains the header name
(which should be in all lower case)
and a set of header control flags (described below),
The flags are:
.ip H_ACHECK
Normally when the check is made to see if a header line is compatible
with a mailer,
.i sendmail
will not delete an existing line.
If this flag is set,
.i sendmail
will delete
even existing header lines.
That is,
if this bit is set and the mailer does not have flag bits set
that intersect with the required mailer flags
in the header definition in
sendmail.cf,
the header line is
.i always
deleted.
.ip H_EOH
If this header field is set,
treat it like a blank line,
i.e.,
it will signal the end of the header
and the beginning of the message text.
.ip H_FORCE
Add this header entry
even if one existed in the message before.
If a header entry does not have this bit set,
.i sendmail
will not add another header line if a header line
of this name already existed.
This would normally be used to stamp the message
by everyone who handled it.
.ip H_TRACE
If set,
this is a timestamp
(trace)
field.
If the number of trace fields in a message
exceeds a preset amount
the message is returned
on the assumption that it has an aliasing loop.
.ip H_RCPT
If set,
this field contains recipient addresses.
This is used by the
.b \-t
flag to determine who to send to
when it is collecting recipients from the message.
.ip H_FROM
This flag indicates that this field
specifies a sender.
The order of these fields in the
.i HdrInfo
table specifies
.i sendmail 's
preference
for which field to return error messages to.
.ip H_ERRORSTO
Addresses in this header should receive error messages.
.ip H_CTE
This header is a Content-Transfer-Encoding header.
.ip H_CTYPE
This header is a Content-Type header.
.ip H_BCC
Strip the value from the header (for Bcc:).
.nr ii 5n
.lp
Let's look at a sample
.i HdrInfo
specification:
.(b
.ta 4n +\w'"content-transfer-encoding", 'u
struct hdrinfo HdrInfo[] =
\&{
/* originator fields, most to least significant */
"resent-sender", H_FROM,
"resent-from", H_FROM,
"sender", H_FROM,
"from", H_FROM,
"full-name", H_ACHECK,
"errors-to", H_FROM\^|\^H_ERRORSTO,
/* destination fields */
"to", H_RCPT,
"resent-to", H_RCPT,
"cc", H_RCPT,
"bcc", H_RCPT\^|\^H_BCC,
/* message identification and control */
"message", H_EOH,
"text", H_EOH,
/* trace fields */
"received", H_TRACE\^|\^H_FORCE,
/* miscellaneous fields */
"content-transfer-encoding", H_CTE,
"content-type", H_CTYPE,
NULL, 0,
};
.)b
This structure indicates that the
.q To: ,
.q Resent-To: ,
and
.q Cc:
fields
all specify recipient addresses.
Any
.q Full-Name:
field will be deleted unless the required mailer flag
(indicated in the configuration file)
is specified.
The
.q Message:
and
.q Text:
fields will terminate the header;
these are used by random dissenters around the network world.
The
.q Received:
field will always be added,
and can be used to trace messages.
.pp
There are a number of important points here.
First,
header fields are not added automatically just because they are in the
.i HdrInfo
structure;
they must be specified in the configuration file
in order to be added to the message.
Any header fields mentioned in the configuration file but not
mentioned in the
.i HdrInfo
structure have default processing performed;
that is,
they are added unless they were in the message already.
Second,
the
.i HdrInfo
structure only specifies cliched processing;
certain headers are processed specially by ad hoc code
regardless of the status specified in
.i HdrInfo .
For example,
the
.q Sender:
and
.q From:
fields are always scanned on ARPANET mail
to determine the sender\**;
.(f
\**Actually, this is no longer true in SMTP;
this information is contained in the envelope.
The older ARPANET protocols did not completely distinguish
envelope from header.
.)f
this is used to perform the
.q "return to sender"
function.
The
.q "From:"
and
.q "Full-Name:"
fields are used to determine the full name of the sender
if possible;
this is stored in the macro
.b $x
and used in a number of ways.
.sh 3 "Restricting Use of Email"
.pp
If it is necessary to restrict mail through a relay,
the
.i checkcompat
routine can be modified.
This routine is called for every recipient address.
It returns an exit status
indicating the status of the message.
The status
.sm EX_OK
accepts the address,
.sm EX_TEMPFAIL
queues the message for a later try,
and other values
(commonly
.sm EX_UNAVAILABLE )
reject the message.
It is up to
.i checkcompat
to print an error message
(using
.i usrerr )
if the message is rejected.
For example,
.i checkcompat
could read:
.(b
.re
.sz -1
.ta 4n +4n +4n +4n +4n +4n +4n
int
checkcompat(to, e)
register ADDRESS *to;
register ENVELOPE *e;
\&{
register STAB *s;
s = stab("private", ST_MAILER, ST_FIND);
if (s != NULL && e\->e_from.q_mailer != LocalMailer &&
to->q_mailer == s->s_mailer)
{
usrerr("No private net mail allowed through this machine");
return (EX_UNAVAILABLE);
}
if (MsgSize > 50000 && bitnset(M_LOCALMAILER, to\->q_mailer))
{
usrerr("Message too large for non-local delivery");
e\->e_flags |= EF_NORETURN;
return (EX_UNAVAILABLE);
}
return (EX_OK);
}
.sz
.)b
This would reject messages greater than 50000 bytes
unless they were local.
The
.i EF_NORETURN
flag can be set in
.i e\(->e_flags
to suppress the return of the actual body
of the message in the error return.
The actual use of this routine is highly dependent on the
implementation,
and use should be limited.
.sh 3 "New Database Map Classes"
.pp
New key maps can be added by creating a class initialization function
and a lookup function.
These are then added to the routine
.i setupmaps.
.pp
The initialization function is called as
.(b
\fIxxx\fP_map_init(MAP *map, char *args)
.)b
The
.i map
is an internal data structure.
The
.i args
is a pointer to the portion of the configuration file line
following the map class name;
flags and filenames can be extracted from this line.
The initialization function must return
.sm true
if it successfully opened the map,
.sm false
otherwise.
.pp
The lookup function is called as
.(b
\fIxxx\fP_map_lookup(MAP *map, char buf[], char **av, int *statp)
.)b
The
.i map
defines the map internally.
The
.i buf
has the input key.
This may be (and often is) used destructively.
The
.i av
is a list of arguments passed in from the rewrite line.
The lookup function should return a pointer to the new value.
If the map lookup fails,
.i *statp
should be set to an exit status code;
in particular, it should be set to
.sm EX_TEMPFAIL
if recovery is to be attempted by the higher level code.
.sh 3 "Queueing Function"
.pp
The routine
.i shouldqueue
is called to decide if a message should be queued
or processed immediately.
Typically this compares the message priority to the current load average.
The default definition is:
.(b
bool
shouldqueue(pri, ctime)
long pri;
time_t ctime;
{
if (CurrentLA < QueueLA)
return false;
return (pri > (QueueFactor / (CurrentLA \- QueueLA + 1)));
}
.)b
If the current load average
(global variable
.i CurrentLA ,
which is set before this function is called)
is less than the low threshold load average
(option
.b x ,
variable
.i QueueLA ),
.i shouldqueue
returns
.sm false
immediately
(that is, it should
.i not
queue).
If the current load average exceeds the high threshold load average
(option
.b X ,
variable
.i RefuseLA ),
.i shouldqueue
returns
.sm true
immediately.
Otherwise, it computes the function based on the message priority,
the queue factor
(option
.b q ,
global variable
.i QueueFactor ),
and the current and threshold load averages.
.pp
An implementation wishing to take the actual age of the message into account
can also use the
.i ctime
parameter,
which is the time that the message was first submitted to
.i sendmail .
Note that the
.i pri
parameter is already weighted
by the number of times the message has been tried
(although this tends to lower the priority of the message with time);
the expectation is that the
.i ctime
would be used as an
.q "escape clause"
to ensure that messages are eventually processed.
.sh 3 "Refusing Incoming SMTP Connections"
.pp
The function
.i refuseconnections
returns
.sm true
if incoming SMTP connections should be refused.
The current implementation is based exclusively on the current load average
and the refuse load average option
(option
.b X ,
global variable
.i RefuseLA ):
.(b
bool
refuseconnections()
{
return (RefuseLA > 0 && CurrentLA >= RefuseLA);
}
.)b
A more clever implementation
could look at more system resources.
.sh 3 "Load Average Computation"
.pp
The routine
.i getla
returns the current load average (as a rounded integer).
The distribution includes several possible implementations.
If you are porting to a new environment
you may need to add some new tweaks.\**
.(f
\**If you do, please send updates to
sendmail@Sendmail.ORG.
.)f
.sh 2 "Configuration in sendmail/daemon.c"
.pp
The file
.i sendmail/daemon.c
contains a number of routines that are dependent
on the local networking environment.
The version supplied assumes you have BSD style sockets.
.pp
In previous releases,
we recommended that you modify the routine
.i maphostname
if you wanted to generalize
.b $[
\&...\&
.b $]
lookups.
We now recommend that you create a new keyed map instead.
.sh 2 "LDAP"
.pp
In this section we assume that
.i sendmail
has been compiled with support for LDAP.
.sh 3 "LDAP Recursion"
.pp
LDAP Recursion allows you to add types to the search attributes on an
LDAP map specification.
The syntax is:
.ip "\-v \fIATTRIBUTE\fP[:\fITYPE\fP[:\fIOBJECTCLASS\fP[|\fIOBJECTCLASS\fP|...]]]
.pp
The new \fITYPE\fPs are:
.nr ii 1i
.ip NORMAL
This attribute type specifies the attribute to add to the results string.
This is the default.
.ip DN
Any matches for this attribute are expected to have a value of a
fully qualified distinguished name.
.i sendmail
will lookup that DN and apply the attributes requested to the
returned DN record.
.ip FILTER
Any matches for this attribute are expected to have a value of an
LDAP search filter.
.i sendmail
will perform a lookup with the same parameters as the original
search but replaces the search filter with the one specified here.
.ip URL
Any matches for this attribute are expected to have a value of an LDAP URL.
.i sendmail
will perform a lookup of that URL and use the results from the attributes
named in that URL.
Note however that the search is done using the current LDAP connection,
regardless of what is specified as the scheme, LDAP host, and LDAP
port in the LDAP URL.
.lp
Any untyped attributes are considered
.sm NORMAL
attributes as described above.
.pp
The optional \fIOBJECTCLASS\fP (| separated) list contains the
objectClass values for which that attribute applies.
If the list is given,
the attribute named will only be used if the LDAP record being returned is a
member of that object class.
Note that if these new value attribute \fITYPE\fPs are used in an
AliasFile
option setting, it will need to be double quoted to prevent
.i sendmail
from misparsing the colons.
.pp
Note that LDAP recursion attributes which do not ultimately point to an
LDAP record are not considered an error.
.sh 4 "Example"
.pp
Since examples usually help clarify, here is an example which uses all
four of the new types:
.(b
O LDAPDefaultSpec=-h ldap.example.com -b dc=example,dc=com
Kexample ldap
-z,
-k (&(objectClass=sendmailMTAAliasObject)(sendmailMTAKey=%0))
-v sendmailMTAAliasValue,mail:NORMAL:inetOrgPerson,
uniqueMember:DN:groupOfUniqueNames,
sendmailMTAAliasSearch:FILTER:sendmailMTAAliasObject,
sendmailMTAAliasURL:URL:sendmailMTAAliasObject
.)b
.pp
That definition specifies that:
.bu
Any value in a
.sm sendmailMTAAliasValue
attribute will be added to the result string regardless of object class.
.bu
The
.sm mail
attribute will be added to the result string if
the LDAP record is a member of the
.sm inetOrgPerson
object class.
.bu
The
.sm uniqueMember
attribute is a recursive attribute, used only in
.sm groupOfUniqueNames
records, and should contain an LDAP DN pointing to another LDAP record.
The desire here is to return the
.sm mail
attribute from those DNs.
.bu
The
.sm sendmailMTAAliasSearch
attribute and
.sm sendmailMTAAliasURL
are both used only if referenced in a
.sm sendmailMTAAliasObject .
They are both recursive, the first for a new LDAP search string and the
latter for an LDAP URL.
.sh 2 "STARTTLS"
.pp
In this section we assume that
.i sendmail
has been compiled with support for STARTTLS.
To properly understand the use of STARTTLS in
.i sendmail ,
it is necessary to understand at least some basics about X.509 certificates
and public key cryptography.
This information can be found in books about SSL/TLS
or on WWW sites, e.g.,
.q https://www.OpenSSL.org/ .
.sh 3 "Certificates for STARTTLS"
.pp
When acting as a server,
.i sendmail
requires X.509 certificates to support STARTTLS:
one as certificate for the server (ServerCertFile and corresponding
private ServerKeyFile)
at least one root CA (CACertFile),
i.e., a certificate that is used to sign other certificates,
and a path to a directory which contains (zero or more) other CAs (CACertPath).
The file specified via
CACertFile
can contain several certificates of CAs.
The DNs of these certificates are sent
to the client during the TLS handshake (as part of the
CertificateRequest) as the list of acceptable CAs.
However, do not list too many root CAs in that file, otherwise
the TLS handshake may fail; e.g.,
.(b
error:14094417:SSL routines:SSL3_READ_BYTES:
sslv3 alert illegal parameter:s3_pkt.c:964:SSL alert number 47
.)b
You should probably put only the CA cert into that file
that signed your own cert(s), or at least only those you trust.
The CACertPath directory must contain the hashes of each CA certificate
as filenames (or as links to them).
Symbolic links can be generated with the following
two (Bourne) shell commands:
.(b
C=FileName_of_CA_Certificate
ln -s $C `openssl x509 -noout -hash < $C`.0
.)b
A better way to do this is to use the
.b c_rehash
command that is part of the OpenSSL distribution
because it handles subject hash collisions
by incrementing the number in the suffix of the filename of the symbolic link,
e.g.,
.b \&.0
to
.b \&.1 ,
and so on.
An X.509 certificate is also required for authentication in client mode
(ClientCertFile and corresponding private ClientKeyFile), however,
.i sendmail
will always use STARTTLS when offered by a server.
The client and server certificates can be identical.
Certificates can be obtained from a certificate authority
or created with the help of OpenSSL.
The required format for certificates and private keys is PEM.
To allow for automatic startup of sendmail, private keys
(ServerKeyFile, ClientKeyFile)
must be stored unencrypted.
The keys are only protected by the permissions of the file system.
Never make a private key available to a third party.
.pp
The options
.i ClientCertFile ,
.i ClientKeyFile ,
.i ServerCertFile ,
and
.i ServerKeyFile
can take a second file name,
which must be separated from the first with a comma
(note: do not use any spaces)
to set up a second cert/key pair.
This can be used to have certs of different types,
e.g., RSA and DSA.
.sh 3 "PRNG for STARTTLS"
.pp
STARTTLS requires a strong pseudo random number generator (PRNG)
to operate properly.
Depending on the TLS library you use, it may be required to explicitly
initialize the PRNG with random data.
OpenSSL makes use of
.b /dev/urandom(4)
if available (this corresponds to the compile flag HASURANDOMDEV).
On systems which lack this support, a random file must be specified in the
.i sendmail.cf
file using the option RandFile.
It is
.b strongly
advised to use the "Entropy Gathering Daemon" EGD
from Brian Warner on those systems to provide useful random data.
In this case,
.i sendmail
must be compiled with the flag EGD, and the
RandFile option must point to the EGD socket.
If neither
.b /dev/urandom(4)
nor EGD are available, you have to make sure
that useful random data is available all the time in RandFile.
If the file hasn't been modified in the last 10 minutes before
it is supposed to be used by
.i sendmail
the content is considered obsolete.
One method for generating this file is:
.(b
openssl rand -out /etc/mail/randfile -rand \c
.i /path/to/file:... \c
256
.)b
See the OpenSSL documentation for more information.
In this case, the PRNG for TLS is only
seeded with other random data if the
.b DontBlameSendmail
option
.b InsufficientEntropy
is set.
This is most likely not sufficient for certain actions, e.g.,
generation of (temporary) keys.
.pp
Please see the OpenSSL documentation or other sources
for further information about certificates, their creation and their usage,
the importance of a good PRNG, and other aspects of TLS.
.sh 2 "Encoding of STARTTLS and AUTH related Macros"
.pp
Macros that contain STARTTLS and AUTH related data which comes from outside
sources, e.g., all macros containing information from certificates,
are encoded to avoid problems with non-printable or special characters.
The latter are '\\', '<', '>', '(', ')', '"', '+', and ' '.
All of these characters are replaced by their value in hexadecimal
with a leading '+'.
For example:
.(b
/C=US/ST=California/O=endmail.org/OU=private/CN=Darth Mail (Cert)/
Email=darth+cert@endmail.org
.)b
is encoded as:
.(b
/C=US/ST=California/O=endmail.org/OU=private/
CN=Darth+20Mail+20+28Cert+29/Email=darth+2Bcert@endmail.org
.)b
(line breaks have been inserted for readability).
The macros which are subject to this encoding are
{cert_subject}, {cert_issuer}, {cn_subject}, {cn_issuer},
as well as
{auth_authen} and {auth_author}.
.sh 2 "DANE"
.pp
Initial support for DANE (see RFC 7672 et.al.)
is available if
.i sendmail
is compiled with the option
.b DANE .
Only TLSA RR 3-1-x (DANE-EE) is currently implemented.
The option
.(b
O DANE=true
.)b
enables this feature at run time
and it automatically adds
.b use_dnssec
and
.b use_edns0
to
.(b
O ResolverOptions
.)b
This requires a (preferrably local)
validating DNS resolver which supports those options.
If the client finds a usable TLSA RR and the check
succeeds the macro
.b ${verify}
is set to
.b TRUSTED .
All non-DNS maps are considered
.i secure
just like DNS lookups with DNSSEC.
Be aware that the implementation might not handle all
error conditions as required by the RFCs.
Moreover, TLSA RRs are not looked up for some features,
e.g.,
.i FallBackSmartHost .
+.sh 2 "EAI"
+.pp
+Experimental support for SMTPUTF8 (EAI, see RFC 6530-6533)
+is available when
+the compile time option
+.b USE_EAI,
+(see also
+.i devtools/Site/site.config.m4.sample
+for other settings that might be needed),
+and the cf option
+.i SMTPUTF8
+are used.
+This allows the use of UTF-8 for envelope addresses
+as well as the entire message.
+DNS lookups are done using the A-label format (Punycode)
+as required by the RFCs.
+For all other interactions with external programs and maps,
+the actual value are used,
+i.e., no conversions between UTF-8 and ASCII encodings are made.
+This applies to
+.\" how to make a list?
+.\" .(l
+the keys in map lookups, which might require to specify both versions in a map;
+the data exchanged with a milter, i.e., each milter must be "8 bit clean";
+mail delivery agents which must be able to handle 8 bit addresses.
+.\" .)l
+Some values must be ASCII as those are used before SMTPUTF8 support
+can be requested, e.g.,
+the macros
+.b $j
+and
+.b $m.
+Please test and provide feedback.
+.sh 2 "MTA-STS"
+.pp
+Experimental support for SMTP MTA Strict Transport Security
+(MTA-STS, see RFC 8461)
+is available when using
+the compile time option _FFR_MTA_STS
+(as well as some others, e.g., _FFR_TLS_ALTNAMES and obviously STARTTLS),
+.\"(which requires in a default setting
+.\"MAP_REGEX, SOCKETMAP, _FFR_TLS_ALTNAMES, and obviously STARTTLS),
+FEATURE(sts)
+(which implicitly sets the cf option StrictTransportSecurity),
+and
+postfix-mta-sts-resolver
+(see https://github.com/Snawoot/postfix-mta-sts-resolver.git).
+.pp
+Note: this implementation uses a socket map to communicate with
+postfix-mta-sts-resolver
+and handles only the values returned by that program,
+which might not fully implement MTA-STS.
+.pp
+If both DANE and MTA-STS are enabled and available for the receiving domain,
+DANE is used because it offers a much higher level of security.
.sh 1 "ACKNOWLEDGEMENTS"
.pp
I've worked on
.i sendmail
for many years,
and many employers have been remarkably patient
about letting me work on a large project
that was not part of my official job.
This includes time on the INGRES Project at
the University of California at Berkeley,
at Britton Lee,
and again on the Mammoth and Titan Projects at Berkeley.
.pp
Much of the second wave of improvements
resulting in version 8.1
should be credited to Bryan Costales of the
International Computer Science Institute.
As he passed me drafts of his book on
.i sendmail
I was inspired to start working on things again.
Bryan was also available to bounce ideas off of.

has become instrumental in all phases of
.i sendmail
support and development,
and was largely responsible for getting versions 8.8 and 8.9
out the door.

.++ A
.+c "COMMAND LINE FLAGS"
.ba 0
.nr ii 1i
.pp
Arguments must be presented with flags before addresses.
The flags are:
.ip \-A\fIx\fP
Select an alternative .cf file which is either
.i sendmail.cf
for
.b \-Am
or
.i submit.cf
for
.b \-Ac .
By default the .cf file is chosen based on the operation mode.
For
.b -bm
(default),
.b -bs ,
and
.b -t
it is
.i submit.cf
if it exists, for all others it is
.i sendmail.cf .
.ip \-b\fIx\fP
Set operation mode to
.i x .
Operation modes are:
.(b
.ta 4n
m Deliver mail (default)
s Speak SMTP on input side
a\(dg ``Arpanet'' mode (get envelope sender information from header)
C Check the configuration file
d Run as a daemon in background
D Run as a daemon in foreground
t Run in test mode
v Just verify addresses, don't collect or deliver
i Initialize the alias database
p Print the mail queue
P Print overview over the mail queue (requires shared memory)
h Print the persistent host status database
H Purge expired entries from the persistent host status database
.)b
.(f
\(dgDeprecated.
.)f
.ip \-B\fItype\fP
Indicate body type.
.ip \-C\fIfile\fP
Use a different configuration file.
.i Sendmail
runs as the invoking user (rather than root)
when this flag is specified.
.ip "\-D \fIlogfile\fP"
Send debugging output to the indicated
.i logfile
instead of stdout.
.ip \-d\fIlevel\fP
Set debugging level.
.ip "\-f\ \fIaddr\fP"
The envelope sender address is set to
.i addr .
This address may also be used in the From: header
if that header is missing during initial submission.
The envelope sender address is used as the recipient
for delivery status notifications
and may also appear in a Return-Path: header.
.ip \-F\ \fIname\fP
Sets the full name of this user to
.i name .
.ip \-G
When accepting messages via the command line,
indicate that they are for relay (gateway) submission.
sendmail may complain about syntactically invalid messages,
e.g., unqualified host names,
rather than fixing them when this flag is set.
sendmail will not do any canonicalization in this mode.
.ip "\-h\ \fIcnt\fP"
Sets the
.q "hop count"
to
.i cnt .
This represents the number of times this message has been processed
by
.i sendmail
(to the extent that it is supported by the underlying networks).
.i Cnt
is incremented during processing,
and if it reaches
MAXHOP
(currently 25)
.i sendmail
throws away the message with an error.
.ip "\-L \fItag\fP"
Sets the identifier used for syslog.
Note that this identifier is set
as early as possible.
However,
.i sendmail
may be used
if problems arise
before the command line arguments
are processed.
.ip \-n
Don't do aliasing or forwarding.
.ip "\-N \fInotifications\fP"
Tag all addresses being sent as wanting the indicated
.i notifications ,
which consists of the word
.q NEVER
or a comma-separated list of
.q SUCCESS ,
.q FAILURE ,
and
.q DELAY
for successful delivery,
failure,
and a message that is stuck in a queue somewhere.
The default is
.q FAILURE,DELAY .
.ip "\-r\ \fIaddr\fP"
An obsolete form of
.b \-f .
.ip \-o\fIx\|value\fP
Set option
.i x
to the specified
.i value .
These options are described in Section 5.6.
.ip \-O\fIoption\fP\fB=\fP\fIvalue\fP
Set
.i option
to the specified
.i value
(for long form option names).
These options are described in Section 5.6.
.ip \-M\fIx\|value\fP
Set macro
.i x
to the specified
.i value .
.ip \-p\fIprotocol\fP
Set the sending protocol.
Programs are encouraged to set this.
The protocol field can be in the form
.i protocol \c
.b : \c
.i host
to set both the sending protocol and sending host.
For example,
.q \-pUUCP:uunet
sets the sending protocol to UUCP
and the sending host to uunet.
(Some existing programs use \-oM to set the r and s macros;
this is equivalent to using \-p.)
.ip \-q\fItime\fP
Try to process the queued up mail.
If the time is given,
.i sendmail
will start one or more processes to run through the queue(s) at the specified
time interval to deliver queued mail; otherwise, it only runs once.
Each of these processes acts on a workgroup.
These processes are also known as workgroup processes or WGP's for short.
Each workgroup is responsible for controlling the processing of one or
more queues; workgroups help manage the use of system resources by sendmail.
Each workgroup may have one or more children concurrently processing
queues depending on the setting of \fIMaxQueueChildren\fP.
.ip \-qp\fItime\fP
Similar to \-q with a time argument,
except that instead of periodically starting WGP's
sendmail starts persistent WGP's
that alternate between processing queues and sleeping.
The sleep time is specified by the time argument; it defaults to 1 second,
except that a WGP always sleeps at least 5 seconds if their queues were
empty in the previous run.
Persistent processes are managed by a queue control process (QCP).
The QCP is the parent process of the WGP's.
Typically the QCP will be the sendmail daemon (when started with \-bd or \-bD)
or a special process (named Queue control) (when started without \-bd or \-bD).
If a persistent WGP ceases to be active for some reason
another WGP will be started by the QCP for the same workgroup
in most cases. When a persistent WGP has core dumped, the debug flag
\fIno_persistent_restart\fP is set or the specific persistent WGP has been
restarted too many times already then the WGP will not be started again
and a message will be logged to this effect.
To stop (SIGTERM) or restart (SIGHUP) persistent WGP's the appropriate
signal should be sent to the QCP. The QCP will propagate the signal to all of
the WGP's and if appropriate restart the persistent WGP's.
.ip \-q\fIGname\fP
Run the jobs in the queue group
.i name
once.
.ip \-q[!]\fIXstring\fP
Run the queue once,
limiting the jobs to those matching
.i Xstring .
The key letter
.i X
can be
.b I
to limit based on queue identifier,
.b R
to limit based on recipient,
.b S
to limit based on sender,
or
.b Q
to limit based on quarantine reason for quarantined jobs.
A particular queued job is accepted if one of the corresponding attributes
contains the indicated
.i string .
The optional ! character negates the condition tested.
Multiple
.i \-q\fIX\fP
flags are permitted,
with items with the same key letter
.q or'ed
together, and items with different key letters
.q and'ed
together.
.ip "\-Q[reason]"
Quarantine normal queue items with the given reason or
unquarantine quarantined queue items if no reason is given.
This should only be used with some sort of item matching using
.b \-q[!]\fIXstring\fP
as described above.
.ip "\-R ret"
What information you want returned if the message bounces;
.i ret
can be
.q HDRS
for headers only or
.q FULL
for headers plus body.
This is a request only;
the other end is not required to honor the parameter.
If
.q HDRS
is specified local bounces also return only the headers.
.ip \-t
Read the header for
.q To: ,
.q Cc: ,
and
.q Bcc:
lines, and send to everyone listed in those lists.
The
.q Bcc:
line will be deleted before sending.
Any addresses in the argument vector will be deleted
from the send list.
+.ip \-U
+This option is required when sending mail using UTF-8;
+it sets the
+.q SMTPUTF8
+argument for
+.q MAIL
+command.
+Only available if
+.q EAI
+support is enabled,
+and the
+.q SMTPUTF8
+option is set.
.ip "\-V envid"
The indicated
.i envid
is passed with the envelope of the message
and returned if the message bounces.
.ip "\-X \fIlogfile\fP"
Log all traffic in and out of
.i sendmail
in the indicated
.i logfile
for debugging mailer problems.
This produces a lot of data very quickly and should be used sparingly.
.pp
There are a number of options that may be specified as
primitive flags.
These are the e, i, m, and v options.
Also,
the f option
may be specified as the
.b \-s
flag.
The DSN related options
.q "\-N" ,
.q "\-R" ,
and
.q "\-V"
have no effects on
.i sendmail
running as daemon.
.+c "QUEUE FILE FORMATS"
.pp
This appendix describes the format of the queue files.
These files live in a queue directory.
The individual qf, hf, Qf, df, and xf files
may be stored in separate
.i qf/ ,
.i df/ ,
and
.i xf/
subdirectories
if they are present in the queue directory.
.pp
All queue files have the name
.i ttYMDhmsNNppppp
where
.i YMDhmsNNppppp
is the
.i id
for this message
and the
.i tt
is a type.
The individual letters in the
.i id
are:
.nr ii 0.5i
.ip Y
Encoded year
.ip M
Encoded month
.ip D
Encoded day
.ip h
Encoded hour
.ip m
Encoded minute
.ip s
Encoded second
.ip NN
Encoded envelope number
.ip ppppp
At least five decimal digits of the process ID
.pp
All files with the same id collectively define one message.
Due to the use of memory-buffered files,
some of these files may never appear on disk.
.pp
The types are:
.nr ii 0.5i
.ip qf
The queue control file.
This file contains the information necessary to process the job.
.ip hf
The same as a queue control file, but for a quarantined queue job.
.ip df
The data file.
The message body (excluding the header) is kept in this file.
Sometimes the df file is not stored in the same directory as the qf file;
in this case,
the qf file contains a `d' record which names the queue directory
that contains the df file.
.ip tf
A temporary file.
This is an image of the
.b qf
file when it is being rebuilt.
It should be renamed to a
.b qf
file very quickly.
.ip xf
A transcript file,
existing during the life of a session
showing everything that happens
during that session.
Sometimes the xf file must be generated before a queue group has been selected;
in this case,
the xf file will be stored in a directory of the default queue group.
.ip Qf
A ``lost'' queue control file.
.i sendmail
renames a
.b qf
file to
.b Qf
if there is a severe (configuration) problem that cannot be solved without
human intervention.
Search the logfile for the queue file id to figure out what happened.
After you resolved the problem, you can rename the
.b Qf
file to
.b qf
and send it again.
.pp
The queue control file is structured as a series of lines
-each beginning with a code letter.
+each beginning with a code letter;
+the file must end with a line containing only a single dot.
The lines are as follows:
.ip V
The version number of the queue file format,
used to allow new
.i sendmail
binaries to read queue files created by older versions.
Defaults to version zero.
Must be the first line of the file if present.
-For 8.12 the version number is 6.
+For 8.13 and later the version number is 8.
.ip A
The information given by the AUTH= parameter of the
-.q "MAIL FROM:"
+.sm "SMTP MAIL"
command or $f@$j
if sendmail has been called directly.
.ip H
A header definition.
There may be any number of these lines.
The order is important:
they represent the order in the final message.
These use the same syntax
as header definitions in the configuration file.
.ip C
The controlling address.
The syntax is
.q localuser:aliasname .
Recipient addresses following this line
will be flagged so that deliveries will be run as the
.i localuser
(a user name from the /etc/passwd file);
.i aliasname
is the name of the alias that expanded to this address
(used for printing messages).
.ip q
The quarantine reason for quarantined queue items.
.ip Q
The ``original recipient'',
specified by the ORCPT= field in an ESMTP transaction.
Used exclusively for Delivery Status Notifications.
It applies only to the following `R' line.
.ip r
The ``final recipient''
used for Delivery Status Notifications.
It applies only to the following `R' line.
.ip R
A recipient address.
This will normally be completely aliased,
but is actually realiased when the job is processed.
There will be one line for each recipient.
Version 1 qf files
also include a leading colon-terminated list of flags,
some of which are
`S' to return a message on successful final delivery,
`F' to return a message on failure,
`D' to return a message if the message is delayed,
`N' to suppress returning the body,
and
`P' to declare this as a ``primary'' (command line or SMTP-session) address.
.ip S
The sender address.
There may only be one of these lines.
.ip T
The job creation time.
This is used to compute when to time out the job.
.ip P
The current message priority.
This is used to order the queue.
Higher numbers mean lower priorities.
The priority changes
as the message sits in the queue.
The initial priority depends on the message class
and the size of the message.
.ip M
A message.
This line is printed by the
.i mailq
command,
and is generally used to store status information.
It can contain any text.
.ip F
Flag bits, represented as one letter per flag.
Defined flag bits are
.b r
indicating that this is a response message
and
.b w
indicating that a warning message has been sent
announcing that the mail has been delayed.
Other flag bits are:
.b 8 :
the body contains 8bit data,
.b b :
a Bcc: header should be removed,
.b d :
the mail has RET parameters (see RFC 1894),
.b n :
the body of the message should not be returned
in case of an error,
.b s :
the envelope has been split.
.ip N
The total number of delivery attempts.
.ip K
The time (as seconds since January 1, 1970)
of the last delivery attempt.
.ip d
If the df file is in a different directory than the qf file,
then a `d' record is present,
specifying the directory in which the df file resides.
.ip I
The i-number of the data file;
this can be used to recover your mail queue
after a disastrous disk crash.
.ip $
A macro definition.
The values of certain macros
are passed through to the queue run phase.
.ip B
The body type.
The remainder of the line is a text string defining the body type.
If this field is missing,
the body type is assumed to be
.q "undefined"
and no special processing is attempted.
Legal values are
.q 7BIT
and
.q 8BITMIME .
.ip Z
The original envelope id (from the ESMTP transaction).
For Deliver Status Notifications only.
.pp
As an example,
the following is a queue file sent to
.q eric@mammoth.Berkeley.EDU
and
.q bostic@okeeffe.CS.Berkeley.EDU \**:
.(f
\**This example is contrived and probably inaccurate for your environment.
Glance over it to get an idea;
nothing can replace looking at what your own system generates.

.+c "SUMMARY OF SUPPORT FILES"
.pp
This is a summary of the support files
that
.i sendmail
creates or generates.
Many of these can be changed by editing the sendmail.cf file;
check there to find the actual pathnames.
.nr ii 1i
.ip "/usr/\*(SD/sendmail"
The binary of
.i sendmail .
.ip /usr/\*(SB/newaliases
A link to /usr/\*(SD/sendmail;
causes the alias database to be rebuilt.
Running this program is completely equivalent to giving
.i sendmail
the
.b \-bi
flag.
.ip /usr/\*(SB/mailq
Prints a listing of the mail queue.
This program is equivalent to using the
.b \-bp
flag to
.i sendmail .
.ip /etc/mail/sendmail.cf
The configuration file,
in textual form.
.ip /etc/mail/helpfile
The SMTP help file.
.ip /etc/mail/statistics
A statistics file; need not be present.
.ip /etc/mail/sendmail.pid
Created in daemon mode;
it contains the process id of the current SMTP daemon.
If you use this in scripts;
use ``head \-1'' to get just the first line;
the second line contains the command line used to invoke the daemon,
and later versions of
.i sendmail
may add more information to subsequent lines.
.ip /etc/mail/aliases
The textual version of the alias file.
.ip /etc/mail/aliases.db
The alias file in
.i hash \|(3)
format.
.ip /etc/mail/aliases.{pag,dir}
The alias file in
.i ndbm \|(3)
format.
.ip /var/spool/mqueue
The directory in which the mail queue(s)
and temporary files reside.
.ip /var/spool/mqueue/qf*
Control (queue) files for messages.
.ip /var/spool/mqueue/df*
Data files.
.ip /var/spool/mqueue/tf*
Temporary versions of the qf files,
used during queue file rebuild.
.ip /var/spool/mqueue/xf*
A transcript of the current session.

.SH DESCRIPTION
.B Editmap
queries or edits one record in database maps used by the keyed map lookups in
sendmail(8).
Arguments are passed on the command line and output (for queries) is
directed to standard output.
.PP
Depending on how it is compiled,
.B editmap
-handles up to three different database formats,
+handles different database formats,
selected using the
.I maptype
-parameter.
+parameter.
They may be
.TP

-DBM format maps.
-This requires the
-ndbm(3)
+DBM format maps.
+This requires the

+CDB (Constant DataBase) format maps.
+This requires the tinycdb library.
.PP
If the
.I TrustedUser
option is set in the sendmail configuration file and
.B editmap
is invoked as root, the generated files will be owned by
the specified
.IR TrustedUser.
.SS Flags
.TP
.B \-C
Use the specified
.B sendmail
configuration file for looking up the TrustedUser option.
.TP
.B \-N
Include the null byte that terminates strings
in the map (for alias maps).
.TP
.B \-f
Normally all upper case letters in the key
are folded to lower case.
This flag disables that behaviour.
This is intended to mesh with the
\-f flag in the
.B K
line in sendmail.cf.
The value is never case folded.
.TP
.B \-q
Query the map for the specified key. If found, print value to standard
output and exit with 0. If not found then print an error
message to stdout and exit with EX_UNAVAILABLE.
.TP
.B \-u
Update the record for
.I key
with
.I value
or inserts a new record if one doesn't exist. Exits with 0 on success
or EX_IOERR on failure.
.TP
.B \-x
Deletes the specific key from the map. Exits with 0 on success or
EX_IOERR on failure.
.TP
.SH SEE ALSO

** SYSEXITS.H -- Exit status codes for system programs.
**
** This include file attempts to categorize possible error
** exit statuses for system programs, notably delivermail
** and the Berkeley network.
**
** Error numbers begin at EX__BASE to reduce the possibility of
** clashing with other exit statuses that random programs may
** already return. The meaning of the codes is approximately
** as follows:
**
** EX_USAGE -- The command was used incorrectly, e.g., with
** the wrong number of arguments, a bad flag, a bad
** syntax in a parameter, or whatever.
** EX_DATAERR -- The input data was incorrect in some way.
** This should only be used for user's data & not
** system files.
** EX_NOINPUT -- An input file (not a system file) did not
** exist or was not readable. This could also include
** errors like "No message" to a mailer (if it cared
** to catch it).
** EX_NOUSER -- The user specified did not exist. This might
** be used for mail addresses or remote logins.
** EX_NOHOST -- The host specified did not exist. This is used
** in mail addresses or network requests.
** EX_UNAVAILABLE -- A service is unavailable. This can occur
** if a support program or file does not exist. This
** can also be used as a catchall message when something
** you wanted to do doesn't work, but you don't know
** why.
** EX_SOFTWARE -- An internal software error has been detected.
** This should be limited to non-operating system related
** errors as possible.
** EX_OSERR -- An operating system error has been detected.
** This is intended to be used for such things as "cannot
** fork", "cannot create pipe", or the like. It includes
** things like getuid returning a user that does not
** exist in the passwd file.
** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
** etc.) does not exist, cannot be opened, or has some
** sort of error (e.g., syntax error).
** EX_CANTCREAT -- A (user specified) output file cannot be
** created.
** EX_IOERR -- An error occurred while doing I/O on some file.
** EX_TEMPFAIL -- temporary failure, indicating something that
** is not really an error. In sendmail, this means
** that a mailer (e.g.) could not create a connection,
** and the request should be reattempted later.
** EX_PROTOCOL -- the remote system returned something that
** was "not possible" during a protocol exchange.
** EX_NOPERM -- You did not have sufficient permission to
** perform the operation. This is not intended for
** file system problems, which should use NOINPUT or
** CANTCREAT, but rather for higher level permissions.

In addition to its own initialization,
libmilter expects a filter to initialize several parameters
before calling <A HREF="smfi_main.html">smfi_main</A>:
<UL>
<LI>The callbacks the filter wishes to be called, and the types of
message modification it intends to perform (required, see
<A HREF="smfi_register.html">smfi_register</A>).
<LI>The socket address to be used when communicating with the MTA
(required, see <A HREF="smfi_setconn.html">smfi_setconn</A>).
<LI>The number of seconds to wait for MTA connections before
timing out (optional, see
<A HREF="smfi_settimeout.html">smfi_settimeout</A>).
</UL>
<P>
If the filter fails to initialize libmilter,
or if one or more of the parameters it has passed are invalid,
a subsequent call to smfi_main will fail.
<H2><A NAME="ControlFlow">Control Flow</A></H2>
<P>
The following pseudocode describes the filtering process from the
perspective of a set of <CODE>N</CODE> MTA's,
each corresponding to a connection.
Callbacks are shown beside the processing stages in which they are invoked;
if no callbacks are defined for a particular stage,
that stage may be bypassed.
Though it is not shown,
processing may be aborted at any time during a message,
in which case the
<A HREF="xxfi_abort.html">xxfi_abort</A> callback is invoked and control
returns to <CODE>MESSAGE</CODE>.

<P>
To write a filter, a vendor supplies callbacks to process relevant
parts of a message transaction.
The library then controls all sequencing, threading,
and protocol exchange with the MTA.
<A HREF="#figure-3">Figure 3</A> outlines control flow for a filter
process, showing where different callbacks are invoked.

</DIV>
<P>
Note that although only a single message is shown above, multiple
messages may be sent in a single connection.
Note also that a message or connection may be aborted by
either the remote host or the MTA
at any point during the SMTP transaction.
If this occurs during a message (between the MAIL command and the final "."),
the filter's
<A HREF="xxfi_abort.html">xxfi_abort</A> routine will be called.
<A HREF="xxfi_close.html">xxfi_close</A> is called any time the
connection closes.
<H2><A NAME="Multithreading">Multithreading</A></H2>
<P>
A single filter process may handle any number of connections
simultaneously.
All filtering callbacks must therefore be reentrant,
and use some appropriate external synchronization methods to access
global data.
Furthermore, since there is not a one-to-one correspondence
between threads and connections
(N connections mapped onto M threads, M &lt;= N),
connection-specific data must be accessed
through the handles provided by the Milter library.
The programmer cannot rely on library-supplied thread-specific data blocks
(e.g., <CODE>pthread_getspecific(3)</CODE>) to store connection-specific data.
See the API documentation for
<A HREF="smfi_setpriv.html">smfi_setpriv</A> and
<A HREF="smfi_getpriv.html">smfi_getpriv</A> for details.
<H2><A NAME="ResourceManagement">Resource Management</A></H2>
Since filters are likely to be long-lived,
and to handle many connections,
proper deallocation of per-connection resources is important.
The lifetime of a connection is bracketed by calls to the
callbacks <A HREF="xxfi_connect.html">xxfi_connect</A> and
<A HREF="xxfi_close.html">xxfi_close</A>.
Therefore connection-specific
resources (accessed via <A HREF="smfi_getpriv.html">smfi_getpriv</A>
and <A HREF="smfi_setpriv.html">smfi_setpriv</A>) may be allocated in
<A HREF="xxfi_connect.html">xxfi_connect</A>,
and should be freed in
<A HREF="xxfi_close.html">xxfi_close</A>.
For further information see
the <A HREF="api.html#conn-msg">discussion</A> of message- versus
connection-oriented routines.
In particular,
note that there is only one connection-specific data pointer per connection.
<P>
Each message is bracketed by calls to
<A HREF="xxfi_envfrom.html">xxfi_envfrom</A> and
<A HREF="xxfi_eom.html">xxfi_eom</A> (or
<A HREF="xxfi_abort.html">xxfi_abort</A>),
implying that message-specific resources can be allocated
and reclaimed in these routines.
Since the messages in a connection are processed sequentially by each filter,
there will be only one active message associated with a given
connection and filter (and connection-private data block).
These resources must still be accessed through
<A HREF="smfi_getpriv.html">smfi_getpriv</A> and
<A HREF="smfi_setpriv.html">smfi_setpriv</A>,
and must be reclaimed in
<A HREF="xxfi_abort.html">xxfi_abort</A>.
<H2><A NAME="SignalHandling">Signal Handling</A></H2>
libmilter takes care of signal handling,
the filters are not influenced directly by signals.
There are basically two types of signal handlers:
<OL>
<LI><TT>Stop</TT>: no new connections from the MTA will be accepted,
but existing connections are allowed to continue.
<LI><TT>Abort</TT>: all filters will be stopped as soon as the next
communication with the MTA happens.
</OL>
Filters are not terminated asynchronously
(except by signals that can't be caught).
In the case of <TT>Abort</TT> the
<A HREF="xxfi_abort.html">xxfi_abort</A> callback is usually invoked
if there is an active transaction.
However, if an invoked callback takes too long to execute
(the maximum time <TT>Abort</TT> waits is currently 5s)
<!-- XREF: MI_CHK_TIME -->
then the filter is simply terminated, i.e.,
neither the
<A HREF="xxfi_abort.html">xxfi_abort</A> callback
nor the
<A HREF="xxfi_close.html">xxfi_close</A> callback
is invoked.

<!----------- Return values ---------->
<TR>
<TH valign="top" align=left>RETURN VALUES</TH>
<TD>smfi_setmlreply will fail and return MI_FAILURE if:
<UL>
<LI>The rcode or xcode argument is invalid.
<LI>A memory-allocation failure occurs.
<LI>If any text line contains a carriage return or line feed.
<LI>The length of any text line is more than MAXREPLYLEN (980).
<LI>More than 32 lines of text replies are given.
</UL>
Otherwise, it return MI_SUCCESS.
</TD>
</TR>
<!----------- Notes ---------->
<TR align="left" valign=top>
<TH>NOTES</TH>
<TD>
<UL>
<LI>Values passed to smfi_setmlreply are not checked for standards compliance.
<LI>The message parameter should contain only printable characters,
other characters may lead to undefined behavior.
For example, CR or LF will cause the call to fail,
single '%' characters will cause the text to be ignored
(if there really should be a '%' in the string,
use '%%' just like for <TT>printf(3)</TT>).
<LI>For details about reply codes and their meanings, please see RFC's
<A href="http://www.rfc-editor.org/rfc/rfc821.txt">821</A>/
<A href="http://www.rfc-editor.org/rfc/rfc2821.txt">2821</A>
and
<A href="http://www.rfc-editor.org/rfc/rfc1893.txt">1893</A>/
<A href="http://www.rfc-editor.org/rfc/rfc2034.txt">2034</A>.
<LI>If the reply code (rcode) given is a '4XX' code but SMFI_REJECT is used
for the message, the custom reply is not used.
<LI>Similarly, if the reply code (rcode) given is a '5XX' code but
SMFI_TEMPFAIL is used for the message, the custom reply is not used.
<BR>
Note: in neither of the last two cases an error is returned to the milter,
libmilter silently ignores the reply code.
<LI>If the milter returns SMFI_TEMPFAIL and sets the reply code to '421',
then the SMTP server will terminate the SMTP session with a 421 error code.

** NI_PROPVAL -- NetInfo property value lookup routine
**
** Parameters:
** keydir -- the NetInfo directory name in which to search
** for the key.
** keyprop -- the name of the property in which to find the
** property we are interested. Defaults to "name".
** keyval -- the value for which we are really searching.
** valprop -- the property name for the value in which we
** are interested.
** sepchar -- if non-nil, this can be multiple-valued, and
** we should return a string separated by this
** character.
**
** Returns:
** NULL -- if:
** 1. the directory is not found
** 2. the property name is not found
** 3. the property contains multiple values
** 4. some error occurred
** else -- the value of the lookup.
**
** Example:
** To search for an alias value, use:
** ni_propval("/aliases", "name", aliasname, "members", ',')
**
** Notes:
** Caller should free the return value of ni_proval

** SM_IO_RD_TIMEOUT -- measured timeout for reads
**
** This #define uses a select() to wait for the 'fd' to become readable.
** The select() can be active for up to 'To' time. The select() may not
** use all of the the 'To' time. Hence, the amount of "wall-clock" time is
** measured to decide how much to subtract from 'To' to update it. On some
** BSD-based/like systems the timeout for a select() is updated for the
** amount of time used. On many/most systems this does not happen. Therefore
** the updating of 'To' must be done ourselves; a copy of 'To' is passed
** since a BSD-like system will have updated it and we don't want to
** double the time used!
** Note: if a valid 'fd' doesn't exist yet, don't use this (e.g. the
** sendmail buffered file type in sendmail/bf.c; see use below).
**
** Parameters
** fp -- the file pointer for the active file
** fd -- raw file descriptor (from 'fp') to use for select()
** to -- struct timeval of the timeout
** timeout -- the original timeout value
** sel_ret -- the return value from the select()

/*
** SMRSH -- sendmail restricted shell
**
** This is a patch to get around the prog mailer bugs in most
** versions of sendmail.
**
** Use this in place of /bin/sh in the "prog" mailer definition
** in your sendmail.cf file. You then create CMDDIR (owned by
** root, mode 755) and put links to any programs you want
** available to prog mailers in that directory. This should
** include things like "vacation" and "procmail", but not "sed"
** or "sh".
**
** Leading pathnames are stripped from program names so that
** existing .forward files that reference things like
** "/usr/bin/vacation" will continue to work.
**
** The following characters are completely illegal:
** < > ^ & ` ( ) \n \r
** The following characters are sometimes illegal:
** | &
** This is more restrictive than strictly necessary.
**
** To use this, add FEATURE(`smrsh') to your .mc file.
**
** This can be used on any version of sendmail.
**
** In loving memory of RTM. 11/02/93.

Sendmail is a trademark of Proofpoint, Inc.
US Patent Numbers 6865671, 6986037.
+-------------------+
| BUILDING SENDMAIL |
+-------------------+
By far, the easiest way to compile sendmail is to use the "Build"
script:
sh ./Build
This uses the "uname" command to figure out what architecture you are
on and creates a proper Makefile accordingly. It also creates a
subdirectory per object format, so that multiarchitecture support is
easy. In general this should be all you need. IRIX 6.x users should
read the note below in the OPERATING SYSTEM AND COMPILE QUIRKS section.
If you need to look at other include or library directories, use the
-I or -L flags on the command line, e.g.,
sh ./Build -I/usr/sww/include -L/usr/sww/lib
It's also possible to create local site configuration in the file
site.config.m4 (or another file settable with the -f flag). This
file contains M4 definitions for various compilation values; the
most useful are:
confMAPDEF -D flags to specify database types to be included
(see below)
confENVDEF -D flags to specify other environment information
confINCDIRS -I flags for finding include files during compilation
confLIBDIRS -L flags for finding libraries during linking
confLIBS -l flags for selecting libraries during linking
confLDOPTS other ld(1) linker options
Others can be found by examining Makefile.m4. Please read
../devtools/README for more information about the site.config.m4
file.
You can recompile from scratch using the -c flag with the Build
command. This removes the existing compilation directory for the
current platform and builds a new one. The -c flag must also
be used if any site.*.m4 file in devtools/Site/ is changed.
Porting to a new Unix-based system should be a matter of creating
an appropriate configuration file in the devtools/OS/ directory.
+----------------------+
| DATABASE DEFINITIONS |
+----------------------+
There are several database formats that can be used for the alias files
and for general maps. When used for alias files they interact in an
attempt to be backward compatible.
The options are:
CDB Constant DataBase, requires tinycdb (0.75), see
http://www.corpit.ru/mjt/tinycdb.html
CDB is included automatically if the Build script can find
a library named libcdb.a or libcdb.so.
By default, .cdb is used as extension for cdb maps, however,
if CDB is set to 2, then .db is used to make transition from
hash maps easier. Note: this usually requires to exclude cdb
from confLIBSEARCH, see devtools/README.
NEWDB The new Berkeley DB package. Some systems (e.g., BSD/OS and
Digital UNIX 4.0) have some version of this package
pre-installed. If your system does not have Berkeley DB
pre-installed, or the version installed is not version 2.0
or greater (e.g., is Berkeley DB 1.85 or 1.86), get the
current version from http://www.sleepycat.com/. DO NOT
use a version from any of the University of California,
Berkeley "Net" or other distributions. If you are still
running BSD/386 1.x, you will need to upgrade the included
Berkeley DB library to a current version. NEWDB is included
automatically if the Build script can find a library named
libdb.a or libdb.so.
See also OPERATING SYSTEM AND COMPILE QUIRKS about Berkeley
DB versions, e.g., DB 4.1.x.
NDBM The older NDBM implementation -- the very old V7 DBM
implementation is no longer supported.
NIS Network Information Services. To use this you must have
NIS support on your system.
NISPLUS NIS+ (the revised NIS released with Solaris 2). You must
have NIS+ support on your system to use this flag.
HESIOD Support for Hesiod (from the DEC/Athena distribution). You
must already have Hesiod support on your system for this to
work. You may be able to get this to work with the MIT/Athena
version of Hesiod, but that's likely to be a lot of work.
BIND 8.X also includes Hesiod support.
LDAPMAP Lightweight Directory Access Protocol support. You will
have to install the UMich or OpenLDAP
(http://www.openldap.org/) ldap and lber libraries to use
this flag.
MAP_REGEX Regular Expression support. You will need to use an
operating system which comes with the POSIX regex()
routines or install a regexp library such as libregex from
the Free Software Foundation.
DNSMAP DNS map support. Requires NAMED_BIND.
-PH_MAP PH map support. You will need the libphclient library from
- the nph package (http://www-dev.cites.uiuc.edu/ph/nph/).
+PH_MAP PH map support.
MAP_NSD nsd map support (IRIX 6.5 and later).
SOCKETMAP Support for a trivial query protocol over UNIX domain or TCP
sockets.
>>> NOTE WELL for NEWDB support: If you want to get ndbm support, for
>>> Berkeley DB versions under 2.0, it is CRITICAL that you remove
>>> ndbm.o from libdb.a before you install it and DO NOT install ndbm.h;
>>> for Berkeley DB versions 2.0 through 2.3.14, remove dbm.o from libdb.a
>>> before you install it. If you don't delete these, there is absolutely
>>> no point to including -DNDBM, since it will just get you another
>>> (inferior) API to the same format database. These files OVERRIDE
>>> calls to ndbm routines -- in particular, if you leave ndbm.h in,
>>> you can find yourself using the new db package even if you don't
>>> define NEWDB. Berkeley DB versions later than 2.3.14 do not need
>>> to be modified. Please also consult the README in the top level
>>> directory of the sendmail distribution for other important information.
>>>
>>> Further note: DO NOT remove your existing /usr/include/ndbm.h --
>>> you need that one. But do not install an updated ndbm.h in
>>> /usr/include, /usr/local/include, or anywhere else.
If NEWDB and NDBM are defined (but not NIS), then sendmail will read
NDBM format alias files, but the next time a newaliases is run the
format will be converted to NEWDB; that format will be used forever
more. This is intended as a transition feature.
If NEWDB, NDBM, and NIS are all defined and the name of the file includes
the string "/yp/", sendmail will rebuild BOTH the NEWDB and NDBM format
alias files. However, it will only read the NEWDB file; the NDBM format
file is used only by the NIS subsystem. This is needed because the NIS
maps on an NIS server are built directly from the NDBM files.
If NDBM and NIS are defined (regardless of the definition of NEWDB),
and the filename includes the string "/yp/", sendmail adds the special
tokens "YP_LAST_MODIFIED" and "YP_MASTER_NAME", both of which are
required if the NDBM file is to be used as an NIS map.
All of these flags are normally defined in a confMAPDEF setting in your
site.config.m4.
If you define NEWDB or HESIOD you get the User Database (USERDB)
automatically. Generally you do want to have NEWDB for it to do
anything interesting. See above for getting the Berkeley DB
package (i.e., NEWDB). There is no separate "user database"
package -- don't bother searching for it on the net.
Hesiod and LDAP require libraries that may not be installed with your
system. These are outside of my ability to provide support. See the
"Quirks" section for more information.
The regex map can be used to see if an address matches a certain regular
expression. For example, all-numerics local parts are common spam
addresses, so "^[0-9]+$" would match this. By using such a map in a
check_* rule-set, you can block a certain range of addresses that would
otherwise be considered valid.
The socket map uses a simple request/reply protocol over TCP or
UNIX domain sockets to query an external server. Both requests and
replies are text based and encoded as netstrings. The socket map
uses the same syntax as milters the specify the remote endpoint,
e.g.:
KmySocketMap socket inet:12345@127.0.0.1
See doc/op/op.me for details.
+---------------+
| COMPILE FLAGS |
+---------------+
Wherever possible, I try to make sendmail pull in the correct
compilation options needed to compile on various environments based on
automatically defined symbols. Some machines don't seem to have useful
symbols available, requiring that a compilation flag be defined in
the Makefile; see the devtools/OS subdirectory for the supported
architectures.
If you are a system to which sendmail has already been ported you
should not have to touch the following symbols. But if you are porting,
you may have to tweak the following compilation flags in conf.h in order
to get it to compile and link properly:
SYSTEM5 Adjust for System V (not necessarily Release 4).
SYS5SIGNALS Use System V signal semantics -- the signal handler
is automatically dropped when the signal is caught.
If this is not set, use POSIX/BSD semantics, where the
signal handler stays in force until an exec or an
explicit delete. Implied by SYSTEM5.
SYS5SETPGRP Use System V setpgrp() semantics. Implied by SYSTEM5.
HASNICE Define this to zero if you lack the nice(2) system call.
HASRRESVPORT Define this to zero if you lack the rresvport(3) system call.
HASFCHMOD Define this to one if you have the fchmod(2) system call.
This improves security.
HASFCHOWN Define this to one if you have the fchown(2) system call.
This is required for the TrustedUser option if sendmail
must rebuild an (alias) map.
HASFLOCK Set this if you prefer to use the flock(2) system call
rather than using fcntl-based locking. Fcntl locking
has some semantic gotchas, but many vendor systems
also interface it to lockd(8) to do NFS-style locking.
Unfortunately, may vendors implementations of fcntl locking
is just plain broken (e.g., locks are never released,
causing your sendmail to deadlock; when the kernel runs
out of locks your system crashes). For this reason, I
recommend always defining this unless you are absolutely
certain that your fcntl locking implementation really works.
HASUNAME Set if you have the "uname" system call. Implied by
SYSTEM5.
HASUNSETENV Define this if your system library has the "unsetenv"
subroutine.
HASSETSID Define this if you have the setsid(2) system call. This
is implied if your system appears to be POSIX compliant.
HASINITGROUPS Define this if you have the initgroups(3) routine.
HASSETVBUF Define this if you have the setvbuf(3) library call.
If you don't, setlinebuf will be used instead. This
defaults on if your compiler defines __STDC__.
HASSETREUID Define this if you have setreuid(2) ***AND*** root can
use setreuid to change to an arbitrary user. This second
condition is not satisfied on AIX 3.x. You may find that
your system has setresuid(2), (for example, on HP-UX) in
which case you will also have to #define setreuid(r, e)
to be the appropriate call. Some systems (such as Solaris)
have a compatibility routine that doesn't work properly,
but may have "saved user ids" properly implemented so you
can ``#define setreuid(r, e) seteuid(e)'' and have it work.
The important thing is that you have a call that will set
the effective uid independently of the real or saved uid
and be able to set the effective uid back again when done.
There's a test program in ../test/t_setreuid.c that will
try things on your system. Setting this improves the
security, since sendmail doesn't have to read .forward
and :include: files as root. There are certain attacks
that may be unpreventable without this call.
USESETEUID Define this to 1 if you have a seteuid(2) system call that
will allow root to set only the effective user id to an
arbitrary value ***AND*** you have saved user ids. This is
preferable to HASSETREUID if these conditions are fulfilled.
These are the semantics of the to-be-released revision of
Posix.1. The test program ../test/t_seteuid.c will try
this out on your system. If you define both HASSETREUID
and USESETEUID, the former is ignored.
HASSETEGID Define this if you have setegid(2) and it can be
used to set the saved gid. Please run t_dropgid in
test/ if you are not sure whether the call works.
HASSETREGID Define this if you have setregid(2) and it can be
used to set the saved gid. Please run t_dropgid in
test/ if you are not sure whether the call works.
HASSETRESGID Define this if you have setresgid(2) and it can be
used to set the saved gid. Please run t_dropgid in
test/ if you are not sure whether the call works.
HASLSTAT Define this if you have symbolic links (and thus the
lstat(2) system call). This improves security. Unlike
most other options, this one is on by default, so you
need to #undef it in conf.h if you don't have symbolic
links (these days everyone does).
HASSETRLIMIT Define this to 1 if you have the setrlimit(2) syscall.
You can define it to 0 to force it off. It is assumed
if you are running a BSD-like system.
HASULIMIT Define this if you have the ulimit(2) syscall (System V
style systems). HASSETRLIMIT overrides, as it is more
general.
HASWAITPID Define this if you have the waitpid(2) syscall.
HASGETDTABLESIZE
Define this if you have the getdtablesize(2) syscall.
HAS_GETHOSTBYNAME2 Define this to 1 if your system supports
gethostbyname2(2).
HAS_ST_GEN Define this to 1 if your system has the st_gen field in
the stat structure (see stat(2)).
HASSRANDOMDEV Define this if your system has the srandomdev(3) function
call.
HASURANDOMDEV Define this if your system has /dev/urandom(4).
HASSTRERROR Define this if you have the libc strerror(3) function (which
should be declared in <errno.h>), and it should be used
instead of sys_errlist.
HASCLOSEFROM Define this if your system has closefrom(3).
HASFDWALK Define this if your system has fdwalk(3).
SM_CONF_GETOPT Define this as 0 if you need a reimplementation of getopt(3).
On some systems, getopt does very odd things if called
to scan the arguments twice. This flag will ask sendmail
to compile in a local version of getopt that works
properly. You may also need this if you build with
another library that introduces a non-standard getopt(3).
NEEDSTRTOL Define this if your standard C library does not define
strtol(3). This will compile in a local version.
NEEDFSYNC Define this if your standard C library does not define
fsync(2). This will try to simulate the operation using
fcntl(2); if that is not available it does nothing, which
isn't great, but at least it compiles and runs.
HASGETUSERSHELL Define this to 1 if you have getusershell(3) in your
standard C library. If this is not defined, or is defined
to be 0, sendmail will scan the /etc/shells file (no
NIS-style support, defaults to /bin/sh and /bin/csh if
that file does not exist) to get a list of unrestricted
user shells. This is used to determine whether users
are allowed to forward their mail to a program or a file.
NEEDPUTENV Define this if your system needs am emulation of the
putenv(3) call. Define to 1 to implement it in terms
of setenv(3) or to 2 to do it in terms of primitives.
NOFTRUNCATE Define this if you don't have the ftruncate(2) syscall.
If you don't have this system call, there is an unavoidable
race condition that occurs when creating alias databases.
+NO_EOH_FIELDS Define this to disable the special handling of the headers
+ Message: and Text: to denote the end of the message header.
GIDSET_T The type of entries in a gidset passed as the second
argument to getgroups(2). Historically this has been an
int, so this is the default, but some systems (such as
IRIX) pass it as a gid_t, which is an unsigned short.
This will make a difference, so it is important to get
this right! However, it is only an issue if you have
group sets.
SLEEP_T The type returned by the system sleep() function.
Defaults to "unsigned int". Don't worry about this
if you don't have compilation problems.
ARBPTR_T The type of an arbitrary pointer -- defaults to "void *".
If you are an very old compiler you may need to define
this to be "char *".
SOCKADDR_LEN_T The type used for the third parameter to accept(2),
getsockname(2), and getpeername(2), representing the
length of a struct sockaddr. Defaults to int.
SOCKOPT_LEN_T The type used for the fifth parameter to getsockopt(2)
and setsockopt(2), representing the length of the option
buffer. Defaults to int.
LA_TYPE The type of load average your kernel supports. These
can be one of:
LA_ZERO (1) -- it always returns the load average as
"zero" (and does so on all architectures).
LA_INT (2) to read /dev/kmem for the symbol avenrun and
interpret as a long integer.
LA_FLOAT (3) same, but interpret the result as a floating
point number.
LA_SHORT (6) to interpret as a short integer.
LA_SUBR (4) if you have the getloadavg(3) routine in your
system library.
LA_MACH (5) to use MACH-style load averages (calls
processor_set_info()),
LA_PROCSTR (7) to read /proc/loadavg and interpret it
as a string representing a floating-point
number (Linux-style).
LA_READKSYM (8) is an implementation suitable for some
versions of SVr4 that uses the MIOC_READKSYM ioctl
call to read /dev/kmem.
LA_DGUX (9) is a special implementation for DG/UX that uses
the dg_sys_info system call.
LA_HPUX (10) is an HP-UX specific version that uses the
pstat_getdynamic system call.
LA_IRIX6 (11) is an IRIX 6.x specific version that adapts
to 32 or 64 bit kernels; it is otherwise very similar
to LA_INT.
LA_KSTAT (12) uses the (Solaris-specific) kstat(3k)
implementation.
LA_DEVSHORT (13) reads a short from a system file (default:
/dev/table/avenrun) and scales it in the same manner
as LA_SHORT.
LA_LONGLONG (17) to read /dev/kmem for the symbol avenrun and
interpret as a long long integer (e.g., for 64 bit
systems).
LA_INT, LA_SHORT, LA_FLOAT, and LA_READKSYM have several
other parameters that they try to divine: the name of your
kernel, the name of the variable in the kernel to examine,
the number of bits of precision in a fixed point load average,
and so forth. LA_DEVSHORT uses _PATH_AVENRUN to find the
device to be read to find the load average.
In desperation, use LA_ZERO. The actual code is in
conf.c -- it can be tweaked if you are brave.
FSHIFT For LA_INT, LA_SHORT, and LA_READKSYM, this is the number
of bits of load average after the binary point -- i.e.,
the number of bits to shift right in order to scale the
integer to get the true integer load average. Defaults to 8.
_PATH_UNIX The path to your kernel. Needed only for LA_INT, LA_SHORT,
and LA_FLOAT. Defaults to "/unix" on System V, "/vmunix"
everywhere else.
LA_AVENRUN For LA_INT, LA_SHORT, and LA_FLOAT, the name of the kernel
variable that holds the load average. Defaults to "avenrun"
on System V, "_avenrun" everywhere else.
SFS_TYPE Encodes how your kernel can locate the amount of free
space on a disk partition. This can be set to SFS_NONE
(0) if you have no way of getting this information,
SFS_USTAT (1) if you have the ustat(2) system call,
SFS_4ARGS (2) if you have a four-argument statfs(2)
system call (and the include file is <sys/statfs.h>),
SFS_VFS (3), SFS_MOUNT (4), SFS_STATFS (5) if you have
the two-argument statfs(2) system call with includes in
<sys/vfs.h>, <sys/mount.h>, or <sys/statfs.h> respectively,
or SFS_STATVFS (6) if you have the two-argument statvfs(2)
call. The default if nothing is defined is SFS_NONE.
SFS_BAVAIL with SFS_4ARGS you can also set SFS_BAVAIL to the field name
in the statfs structure that holds the useful information;
this defaults to f_bavail.
SPT_TYPE Encodes how your system can display what a process is doing
on a ps(1) command (SPT stands for Set Process Title). Can
be set to:
SPT_NONE (0) -- Don't try to set the process title at all.
SPT_REUSEARGV (1) -- Pad out your argv with the information;
this is the default if none specified.
SPT_BUILTIN (2) -- The system library has setproctitle.
SPT_PSTAT (3) -- Use the PSTAT_SETCMD option to pstat(2)
to set the process title; this is used by HP-UX.
SPT_PSSTRINGS (4) -- Use the magic PS_STRINGS pointer (4.4BSD).
SPT_SYSMIPS (5) -- Use sysmips() supported by NEWS-OS 6.
SPT_SCO (6) -- Write kernel u. area.
SPT_CHANGEARGV (7) -- Write pointers to our own strings into
the existing argv vector.
SPT_PADCHAR Character used to pad the process title; if undefined,
the space character (0x20) is used. This is ignored if
SPT_TYPE != SPT_REUSEARGV
ERRLIST_PREDEFINED
If set, assumes that some header file defines sys_errlist.
This may be needed if you get type conflicts on this
variable -- otherwise don't worry about it.
WAITUNION The wait(2) routine takes a "union wait" argument instead
of an integer argument. This is for compatibility with
old versions of BSD.
SCANF You can set this to extend the F command to accept a
scanf string -- this gives you a primitive parser for
class definitions -- BUT it can make you vulnerable to
core dumps if the target file is poorly formed.
SYSLOG_BUFSIZE You can define this to be the size of the buffer that
syslog accepts. If it is not defined, it assumes a
1024-byte buffer. If the buffer is very small (under
256 bytes) the log message format changes -- each
e-mail message will log many more messages, since it
will log each piece of information as a separate line
in syslog.
BROKEN_RES_SEARCH
On Ultrix (and maybe other systems?) if you use the
res_search routine with an unknown host name, it returns
-1 but sets h_errno to 0 instead of HOST_NOT_FOUND. If
you set this, sendmail considers 0 to be the same as
HOST_NOT_FOUND.
NAMELISTMASK If defined, values returned by nlist(3) are masked
against this value before use -- a common value is
0x7fffffff to strip off the top bit.
BSD4_4_SOCKADDR If defined, socket addresses have an sa_len field that
defines the length of this address.
SAFENFSPATHCONF Set this to 1 if and only if you have verified that a
pathconf(2) call with _PC_CHOWN_RESTRICTED argument on an
NFS filesystem where the underlying system allows users to
give away files to other users returns <= 0. Be sure you
try both on NFS V2 and V3. Some systems assume that their
local policy apply to NFS servers -- this is a bad
assumption! The test/t_pathconf.c program will try this
for you -- you have to run it in a directory that is
mounted from a server that allows file giveaway.
SIOCGIFCONF_IS_BROKEN
Set this if your system has an SIOCGIFCONF ioctl defined,
but it doesn't behave the same way as "most" systems (BSD,
Solaris, SunOS, HP-UX, etc.)
SIOCGIFNUM_IS_BROKEN
Set this if your system has an SIOCGIFNUM ioctl defined,
but it doesn't behave the same way as "most" systems
(Solaris, HP-UX).
FAST_PID_RECYCLE
Set this if your system can reuse the same PID in the same
second.
SO_REUSEADDR_IS_BROKEN
Set this if your system has a setsockopt() SO_REUSEADDR
flag but doesn't pay attention to it when trying to bind a
socket to a recently closed port.
NEEDSGETIPNODE Set this if your system supports IPv6 but doesn't include
the getipnodeby{name,addr}() functions. Set automatically
for Linux's glibc.
PIPELINING Support SMTP PIPELINING (set by default).
USING_NETSCAPE_LDAP
Deprecated in favor of SM_CONF_LDAP_MEMFREE. See
libsm/README.
NEEDLINK Set this if your system doesn't have a link() call. It
will create a copy of the file instead of a hardlink.
USE_ENVIRON Set this to 1 to access process environment variables from
the external variable environ instead of the third
parameter of main().
USE_DOUBLE_FORK By default this is on (1). Set it to 0 to suppress the
extra fork() used to avoid intermediate zombies.
ALLOW_255 Do not convert (char)0xff to (char)0x7f in headers etc.
This can also be done at runtime with the command line
option -d82.101.
NEEDINTERRNO Set this if <errno.h> does not declare errno, i.e., if an
application needs to use
extern int errno;
USE_TTYPATH Set this to 1 to enable ErrorMode=write.
USESYSCTL Use sysctl(3) to determine the number of CPUs in a system.
HASSNPRINTF Set this to 1 if your OS has a working snprintf(3), i.e.,
it properly obeys the size of the buffer and returns the
number of characters that would have been printed if the
size were unlimited.
LDAP_REFERRALS Set this if you want to use the -R flag (do not auto chase
referrals) for LDAP maps (requires -DLDAPMAP).
MILTER_NO_NAGLE Turn off Nagle algorithm for communication with libmilter
("cork" on Linux). On some operating systems this may
improve the interprocess communication performance.
+-----------------------+
| COMPILE-TIME FEATURES |
+-----------------------+
There are a bunch of features that you can decide to compile in, such
as selecting various database packages and special protocol support.
Several are assumed based on other compilation flags -- if you want to
"un-assume" something, you probably need to edit conf.h. Compilation
flags that add support for special features include:
CDB Include support for tinycdb.
NDBM Include support for "new" DBM library for aliases and maps.
Normally defined in the Makefile.
NEWDB Include support for Berkeley DB package (hash & btree)
for aliases and maps. Normally defined in the Makefile.
If the version of NEWDB you have is the old one that does
not include the "fd" call (this call was added in version
1.5 of the Berkeley DB code), you must upgrade to the
current version of Berkeley DB.
NIS Define this to get NIS (YP) support for aliases and maps.
Normally defined in the Makefile.
NISPLUS Define this to get NIS+ support for aliases and maps.
Normally defined in the Makefile.
HESIOD Define this to get Hesiod support for aliases and maps.
Normally defined in the Makefile.
NETINFO Define this to get NeXT NetInfo support for aliases and maps.
Normally defined in the Makefile.
LDAPMAP Define this to get LDAP support for maps.
PH_MAP Define this to get PH support for maps.
MAP_NSD Define this to get nsd support for maps.
USERDB Define this to 1 to include support for the User Information
Database. Implied by NEWDB or HESIOD. You can use
-DUSERDB=0 to explicitly turn it off.
IDENTPROTO Define this as 1 to get IDENT (RFC 1413) protocol support.
This is assumed unless you are running on Ultrix or
HP-UX, both of which have a problem in the UDP
implementation. You can define it to be 0 to explicitly
turn off IDENT protocol support. If defined off, the code
is actually still compiled in, but it defaults off; you
can turn it on by setting the IDENT timeout in the
configuration file.
IP_SRCROUTE Define this to 1 to get IP source routing information
displayed in the Received: header. This is assumed on
most systems, but some (e.g., Ultrix) apparently have a
broken version of getsockopt that doesn't properly
support the IP_OPTIONS call. You probably want this if
your OS can cope with it. Symptoms of failure will be that
it won't compile properly (that is, no support for fetching
IP_OPTIONs), or it compiles but source-routed TCP connections
either refuse to open or open and hang for no apparent reason.
Ultrix and AIX3 are known to fail this way.
LOG Set this to get syslog(3) support. Defined by default
in conf.h. You want this if at all possible.
NETINET Set this to get TCP/IP support. Defined by default
in conf.h. You probably want this.
NETINET6 Set this to get IPv6 support. Other configuration may
be needed in conf.h for your particular operating system.
Also, DaemonPortOptions must be set appropriately for
sendmail to accept IPv6 connections.
NETISO Define this to get ISO networking support.
NETUNIX Define this to get Unix domain networking support. Defined
by default. A few bizarre systems (SCO, ISC, Altos) don't
support this networking domain.
NETNS Define this to get NS networking support.
NETX25 Define this to get X.25 networking support.
NAMED_BIND If non-zero, include DNS (name daemon) support, including
MX support. The specs say you must use this if you run
SMTP. You don't have to be running a name server daemon
on your machine to need this -- any use of the DNS resolver,
including remote access to another machine, requires this
option. Defined by default in conf.h. Define it to zero
ONLY on machines that do not use DNS in any way.
MATCHGECOS Permit fuzzy matching of user names against the full
name (GECOS) field in the /etc/passwd file. This should
probably be on, since you can disable it from the config
file if you want to. Defined by default in conf.h.
MIME8TO7 If non-zero, include 8 to 7 bit MIME conversions. This
also controls advertisement of 8BITMIME in the ESMTP
startup dialogue.
MIME7TO8_OLD If 0 then use an algorithm for MIME 7-bit quoted-printable
or base64 encoding to 8-bit text that has been introduced
in 8.12.3. There are some examples where that code fails,
but the old code works. If you have an example of improper
7 to 8 bit conversion please send it to sendmail-bugs.
MIME7TO8 If non-zero, include 7 to 8 bit MIME conversions.
HES_GETMAILHOST Define this to 1 if you are using Hesiod with the
hes_getmailhost() routine. This is included with the MIT
Hesiod distribution, but not with the DEC Hesiod distribution.
XDEBUG Do additional internal checking. These don't cost too
much; you might as well leave this on.
TCPWRAPPERS Turns on support for the TCP wrappers library (-lwrap).
See below for further information.
SECUREWARE Enable calls to the SecureWare luid enabling/changing routines.
SecureWare is a C2 security package added to several UNIX's
(notably ConvexOS) to get a C2 Secure system. This
option causes mail delivery to be done with the luid of the
recipient.
SHARE_V1 Support for the fair share scheduler, version 1. Setting to
1 causes final delivery to be done using the recipients
resource limitations. So far as I know, this is only
supported on ConvexOS.
SASL Enables SMTP AUTH (RFC 2554). This requires the Cyrus SASL
library (ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/). Please
install at least version 1.5.13. See below for further
information: SASL COMPILATION AND CONFIGURATION. If your
SASL library is older than 1.5.10, you have to set this
to its version number using a simple conversion: a.b.c
-> c + b*100 + a*10000, e.g. for 1.5.9 define SASL=10509.
Note: Using an older version than 1.5.5 of Cyrus SASL is
not supported. Starting with version 1.5.10, setting SASL=1
is sufficient. Any value other than 1 (or 0) will be
compared with the actual version found and if there is a
mismatch, compilation will fail.
EGD Define this if your system has EGD installed, see
http://egd.sourceforge.net/ . It should be used to
seed the PRNG for STARTTLS if HASURANDOMDEV is not defined.
STARTTLS Enables SMTP STARTTLS (RFC 2487). This requires OpenSSL
(http://www.OpenSSL.org/); use OpenSSL 0.9.8zc or later.
See STARTTLS COMPILATION AND CONFIGURATION for further
information.
TLS_EC Enable use of elliptic curve cryptography in STARTTLS.
If set to 2 sendmail uses SSL_CTX_set_ecdh_auto(),
if set to 1 it selects the NID_X9_62_prime256v1 curve
(created via EC_KEY_new_by_curve_name()) and uses
SSL_CTX_set_tmp_ecdh().
Support offered by different TLS libraries varies
greatly: some old versions do not support elliptic curve
cryptography at all, some new versions have it enabled
by default (i.e., no need to set TLS_EC at all), while
others may require one of the above settings.
TLS_NO_RSA Turn off support for RSA algorithms in STARTTLS.
MILTER Turn on support for external filters using the Milter API;
this option is set by default, to turn it off use
APPENDDEF(`conf_sendmail_ENVDEF', `-DMILTER=0')
in devtools/Site/site.config.m4 (see devtools/README).
See libmilter/README for more information about milter.
REQUIRES_DIR_FSYNC Turn on support for file systems that require to
call fsync() for a directory if the meta-data in it has
been changed. This should be turned on at least for older
versions of ReiserFS; it is enabled by default for Linux.
According to some information this flag is not needed
anymore for kernel 2.4.16 and newer. We would appreciate
feedback about the semantics of the various file systems
available for Linux.
An alternative to this compile time flag is to mount the
queue directory without the -async option, or using
chattr +S on Linux.
DBMMODE The default file permissions to use when creating new
database files for maps and aliases. Defaults to 0640.
IPV6_FULL Use uncompressed IPv6 addresses (set by default). This
permits a zero subnet to have a more specific match,
such as different map entries for IPv6:0:0 vs IPv6:0.
Generic notice: If you enable a compile time option that needs
libraries or include files that don't come with sendmail or are
installed in a location that your C compiler doesn't use by default
you should set confINCDIRS and confLIBDIRS as explained in the
first section: BUILDING SENDMAIL.
+---------------------+
| DNS/RESOLVER ISSUES |
+---------------------+
Many systems have old versions of the resolver library. At a minimum,
you should be running BIND 4.8.3; older versions may compile, but they
have known bugs that should give you pause.
Common problems in old versions include "undefined" errors for
dn_skipname.
Some people have had a problem with BIND 4.9; it uses some routines
that it expects to be externally defined such as strerror(). It may
help to link with "-l44bsd" to solve this problem. This has apparently
been fixed in later versions of BIND, starting around 4.9.3. In other
words, if you use 4.9.0 through 4.9.2, you need -l44bsd; for earlier or
later versions, you do not.
!PLEASE! be sure to link with the same version of the resolver as
the header files you used -- some people have used the 4.9 headers
and linked with BIND 4.8 or vice versa, and it doesn't work.
Unfortunately, it doesn't fail in an obvious way -- things just
subtly don't work.
WILDCARD MX RECORDS ARE A BAD IDEA! The only situation in which they
work reliably is if you have two versions of DNS, one in the real world
which has a wildcard pointing to your firewall, and a completely
different version of the database internally that does not include
wildcard MX records that match your domain. ANYTHING ELSE WILL GIVE
YOU HEADACHES!
When attempting to canonify a hostname, some broken name servers will
return SERVFAIL (a temporary failure) on T_AAAA (IPv6) lookups. If you
want to excuse this behavior, include WorkAroundBrokenAAAA in
ResolverOptions. However, instead, we recommend catching the problem and
reporting it to the name server administrator so we can rid the world of
broken name servers.
+----------------------------------------+
| STARTTLS COMPILATION AND CONFIGURATION |
+----------------------------------------+
Please read the documentation accompanying the OpenSSL library. You
have to compile and install the OpenSSL libraries before you can compile
sendmail. See devtools/README how to set the correct compile time
parameters; you should at least set the following variables:
APPENDDEF(`conf_sendmail_ENVDEF', `-DSTARTTLS')
APPENDDEF(`conf_sendmail_LIBS', `-lssl -lcrypto')
If you have installed the OpenSSL libraries and include files in
a location that your C compiler doesn't use by default you should
set confINCDIRS and confLIBDIRS as explained in the first section:
BUILDING SENDMAIL.
Configuration information can be found in doc/op/op.me (required
certificates) and cf/README (how to tell sendmail about certificates).
To perform an initial test, connect to your sendmail daemon
(telnet localhost 25) and issue a EHLO localhost and see whether
250-STARTTLS
is in the response. If it isn't, run the daemon with
-O LogLevel=14
and try again. Then take a look at the logfile and see whether
there are any problems listed about permissions (unsafe files)
or the validity of X.509 certificates.
From: Garrett Wollman <wollman@lcs.mit.edu>
If your certificate authority is hierarchical, and you only include
the top-level CA certificate in the CACertFile file, some mail clients
may be unable to infer the proper certificate chain when selecting a
client certificate. Including the bottom-level CA certificate(s) in
the CACertFile file will allow these clients to work properly. This
is not necessary if you are not using client certificates for
authentication, or if all your clients are running Sendmail or other
programs using the OpenSSL library (which get it right automatically).
In addition, some mail clients are totally incapable of using
certificate authentication -- even some of those which already support
SSL/TLS for confidentiality.

+------------------------------------+
| SASL COMPILATION AND CONFIGURATION |
+------------------------------------+
Please read the documentation accompanying the Cyrus SASL library
-(INSTALL and README). If you use Berkeley DB for Cyrus SASL then
-you must compile sendmail with the same version of Berkeley DB.
-See devtools/README for how to set the correct compile time parameters;
-you should at least set the following variables:

You have to select and install authentication mechanisms and tell
sendmail where to find the sasl library and the include files (see
devtools/README for the parameters to set). Set up the required
users and passwords as explained in the SASL documentation. See
also cf/README for authentication related options (especially
-DefaultAuthInfo if you want authentication between MTAs).

+-------------------------------------+
GCC problems
When compiling with "gcc -O -Wall" specify "-DSM_OMIT_BOGUS_WARNINGS"
too (see include/sm/cdefs.h for more info).
*****************************************************************
** IMPORTANT: DO NOT USE OPTIMIZATION (``-O'') IF YOU ARE **
** RUNNING GCC 2.4.x or 2.5.x. THERE IS A BUG IN THE GCC **
** OPTIMIZER THAT CAUSES SENDMAIL COMPILES TO FAIL MISERABLY. **
*****************************************************************
Jim Wilson of Cygnus believes he has found the problem -- it will
probably be fixed in GCC 2.5.6 -- but until this is verified, be
very suspicious of gcc -O. This problem is reported to have been
fixed in gcc 2.6.
A bug in gcc 2.5.5 caused problems compiling sendmail 8.6.5 with
optimization on a Sparc. If you are using gcc 2.5.5, youi should
upgrade to the latest version of gcc.
Apparently GCC 2.7.0 on the Pentium processor has optimization
problems. I recommend against using -O on that architecture. This
has been seen on FreeBSD 2.0.5 RELEASE.
Solaris 2.X users should use version 2.7.2.3 over 2.7.2.
We have been told there are problems with gcc 2.8.0. If you are
using this version, you should upgrade to 2.8.1 or later.
Berkeley DB
Berkeley DB 4.1.x with x <= 24 does not work with sendmail.
You need at least 4.1.25.
GDBM GDBM does not work with sendmail because the additional
security checks and file locking cause problems. Unfortunately,
gdbm does not provide a compile flag in its version of ndbm.h so
the code can adapt. Until the GDBM authors can fix these problems,
GDBM will not be supported. Please use Berkeley DB instead.
Configuration file location
Up to 8.6, sendmail tried to find the sendmail.cf file in the same
place as the vendors had put it, even when this was obviously
stupid. As of 8.7, sendmail ALWAYS looks for /etc/sendmail.cf.
Beginning with 8.10, sendmail uses /etc/mail/sendmail.cf.
You can get sendmail to use the stupid vendor .cf location by
adding -DUSE_VENDOR_CF_PATH during compilation, but this may break
support programs and scripts that need to find sendmail.cf. You
are STRONGLY urged to use symbolic links if you want to use the
vendor location rather than changing the location in the sendmail
binary.
NETINFO systems use NETINFO to determine the location of
sendmail.cf. The full path to sendmail.cf is stored as the value of
the "sendmail.cf" property in the "/locations/sendmail"
subdirectory of NETINFO. Set the value of this property to
"/etc/mail/sendmail.cf" (without the quotes) to use this new
default location for Sendmail 8.10.0 and higher.
ControlSocket permissions
Paraphrased from BIND 8.2.1's README:
Solaris and other pre-4.4BSD kernels do not respect ownership or
protections on UNIX-domain sockets. The short term fix for this is to
override the default path and put such control sockets into root-
owned directories which do not permit non-root to r/w/x through them.
The long term fix is for all kernels to upgrade to 4.4BSD semantics.
HP MPE/iX
The MPE-specific code within sendmail emulates a set-user-id root
environment for the sendmail binary. But there is no root uid 0 on
MPE, nor is there any support for set-user-id programs. Even when
sendmail thinks it is running as uid 0, it will still have the file
access rights of the underlying non-zero uid, but because sendmail is
an MPE priv-mode program it will still be able to call setuid() to
successfully switch to a new uid.
MPE setgid() semantics don't quite work the way sendmail expects, so
special emulation is done here also.
This uid/gid emulation is enabled via the setuid/setgid file mode bits
which are not currently used by MPE. Code in libsm/mpeix.c examines
these bits and enables emulation if they have been set, i.e.,
chmod u+s,g+s /SENDMAIL/CURRENT/SENDMAIL.
SunOS 4.x (Solaris 1.x)
You may have to use -lresolv on SunOS. However, beware that
this links in a new version of gethostbyname that does not
understand NIS, so you must have all of your hosts in DNS.
Some people have reported problems with the SunOS version of
-lresolv and/or in.named, and suggest that you get a newer
version. The symptoms are delays when you connect to the
SMTP server on a SunOS machine or having your domain added to
addresses inappropriately. There is a version of BIND
version 4.9 on gatekeeper.DEC.COM in pub/BSD/bind/4.9.
There is substantial disagreement about whether you can make
this work with resolv+, which allows you to specify a search-path
of services. Some people report that it works fine, others
claim it doesn't work at all (including causing sendmail to
drop core when it tries to do multiple resolv+ lookups for a
single job). I haven't tried resolv+, as we use DNS exclusively.
Should you want to try resolv+, it is on ftp.uu.net in
/networking/ip/dns.
Apparently getservbyname() can fail under moderate to high
load under some circumstances. This will exhibit itself as
the message ``554 makeconnection: service "smtp" unknown''.
The problem has been traced to one or more blank lines in
/etc/services on the NIS server machine. Delete these
and it should work. This info is thanks to Brian Bartholomew
<bb@math.ufl.edu> of I-Kinetics, Inc.
NOTE: The SunOS 4.X linker uses library paths specified during
compilation using -L for run-time shared library searches.
Therefore, it is vital that relative and unsafe directory paths not
be used when compiling sendmail.
SunOS 4.0.2 (Sun 386i)
Date: Fri, 25 Aug 1995 11:13:58 +0200 (MET DST)
From: teus@oce.nl
Sendmail 8.7.Beta.12 compiles and runs nearly out of the box with the
following changes:
* Don't use /usr/5bin in your PATH, but make /usr/5bin/uname
available as "uname" command.
* Use the defines "-DBSD4_3 -DNAMED_BIND=0" in
devtools/OS/SunOS.4.0, which is selected via the "uname" command.
I recommend to make available the db-library on the system first
(and change the Makefile to use this library).
Note that the sendmail.cf and aliases files are found in /etc.
SunOS 4.1.3, 4.1.3_U1
Sendmail causes crashes on SunOS 4.1.3 and 4.1.3_U1. According
to Sun bug number 1077939:
If an application does a getsockopt() on a SOCK_STREAM (TCP) socket
after the other side of the connection has sent a TCP RESET for
the stream, the kernel gets a Bus Trap in the tcp_ctloutput() or
ip_ctloutput() routine.
For 4.1.3, this is fixed in patch 100584-08, available on the
Sunsolve 2.7.1 or later CDs. For 4.1.3_U1, this was fixed in patch
101790-01 (SunOS 4.1.3_U1: TCP socket and reset problems), later
obsoleted by patch 102010-05.
Sun patch 100584-08 is not currently publicly available on their
ftp site but a user has reported it can be found at other sites
using a web search engine.
Solaris 2.x (SunOS 5.x)
To compile for Solaris, the Makefile built by Build must
include a SOLARIS definition which reflects the Solaris version
(i.e. -DSOLARIS=20400 for 2.4 or -DSOLARIS=20501 for 2.5.1).
If you are using gcc, make sure -I/usr/include is not used (or
it might complain about TopFrame). If you are using Sun's cc,
make sure /opt/SUNWspro/bin/cc is used instead of /usr/ucb/cc
(or it might complain about tm_zone).
The Solaris 2.x (x <= 3) "syslog" function is apparently limited
to something about 90 characters because of a kernel limitation.
If you have source code, you can probably up this number. You
can get patches that fix this problem: the patch ids are:
Solaris 2.1 100834
Solaris 2.2 100999
Solaris 2.3 101318
Be sure you have the appropriate patch installed or you won't
see system logging.
Solaris 2.4 (SunOS 5.4)
If you include /usr/lib at the end of your LD_LIBRARY_PATH you run
the risk of getting the wrong libraries under some circumstances.
This is because of a new feature in Solaris 2.4, described by
Rod.Evans@Eng.Sun.COM:
>> Prior to SunOS 5.4, any LD_LIBRARY_PATH setting was ignored by the
>> runtime linker if the application was setxid (secure), thus your
>> applications search path would be:
>>
>> /usr/local/lib LD_LIBRARY_PATH component - IGNORED
>> /usr/lib LD_LIBRARY_PATH component - IGNORED
>> /usr/local/lib RPATH - honored
>> /usr/lib RPATH - honored
>>
>> the effect is that path 3 would be the first used, and this would
>> satisfy your resolv.so lookup.
>>
>> In SunOS 5.4 we made the LD_LIBRARY_PATH a little more flexible.
>> People who developed setxid applications wanted to be able to alter
>> the library search path to some degree to allow for their own
>> testing and debugging mechanisms. It was decided that the only
>> secure way to do this was to allow a `trusted' path to be used in
>> LD_LIBRARY_PATH. The only trusted directory we presently define
>> is /usr/lib. Thus a set-user-ID root developer could play with some
>> alternative shared object implementations and place them in

Solaris 2.5.1 (SunOS 5.5.1) and 2.6 (SunOS 5.6)
Apparently Solaris 2.5.1 patch 103663-01 installs a new
/usr/include/resolv.h file that defines the __P macro without
checking to see if it is already defined. This new resolv.h is also
included in the Solaris 2.6 distribution. This causes compile
warnings such as:
In file included from daemon.c:51:
/usr/include/resolv.h:208: warning: `__P' redefined
cdefs.h:58: warning: this is the location of the previous definition
These warnings can be safely ignored or you can create a resolv.h
file in the obj.SunOS.5.5.1.* or obj.SunOS.5.6.* directory that reads:
#undef __P
#include "/usr/include/resolv.h"
This problem was fixed in Solaris 7 (Sun bug ID 4081053).
Solaris 7 (SunOS 5.7)
Solaris 7 includes LDAP libraries but the implementation was
lacking a few things. The following settings can be placed in
devtools/Site/site.SunOS.5.7.m4 if you plan on using those
libraries.
APPENDDEF(`confMAPDEF', `-DLDAPMAP')
APPENDDEF(`confENVDEF', `-DLDAP_VERSION_MAX=3')
APPENDDEF(`confLIBS', `-lldap')
Also, Sun's patch 107555 is needed to prevent a crash in the call
to ldap_set_option for LDAP_OPT_REFERRALS in ldapmap_setopts if
LDAP support is compiled in sendmail.
Solaris 8 and later (SunOS 5.8 and later)
Solaris 8 and later can optionally install LDAP support. If you
have installed the Entire Distribution meta-cluster, you can use
the following in devtools/Site/site.SunOS.5.8.m4 (or other
appropriately versioned file) to enable LDAP:
APPENDDEF(`confMAPDEF', `-DLDAPMAP')
APPENDDEF(`confLIBS', `-lldap')
Solaris 9 and later (SunOS 5.9 and later)
Solaris 9 and later have a revised LDAP library, libldap.so.5,
which is derived from a Netscape implementation, thus requiring
that SM_CONF_LDAP_MEMFREE be defined in conjunction with LDAPMAP:
APPENDDEF(`confMAPDEF', `-DLDAPMAP')
APPENDDEF(`confENVDEF', `-DSM_CONF_LDAP_MEMFREE')
APPENDDEF(`confLIBS', `-lldap')
Solaris
If you are using dns for hostname resolution on Solaris, make sure
that the 'dns' entry is last on the hosts line in
'/etc/nsswitch.conf'. For example, use:
hosts: nisplus files dns
Do not use:
hosts: nisplus dns [NOTFOUND=return] files
Note that 'nisplus' above is an illustration. The same comment
applies no matter what naming services you are using. If you have
anything other than dns last, even after "[NOTFOUND=return]",
sendmail may not be able to determine whether an error was
temporary or permanent. The error returned by the solaris
gethostbyname() is the error for the last lookup used, and other
naming services do not have the same concept of temporary failure.
Ultrix
By default, the IDENT protocol is turned off on Ultrix. If you
are running Ultrix 4.4 or later, or if you have included patch
CXO-8919 for Ultrix 4.2 or 4.3 to fix the TCP problem, you can turn
IDENT on in the configuration file by setting the "ident" timeout.
The Ultrix 4.5 Y2K patch (ULTV45-022-1) has changed the resolver
included in libc.a. Unfortunately, the __RES symbol hasn't changed
and therefore, sendmail can no longer automatically detect the
newer version. If you get a compiler error:
/lib/libc.a(gethostent.o): local_hostname_length: multiply defined
Then rebuild with this in devtools/Site/site.ULTRIX.m4:
APPENDDEF(`conf_sendmail_ENVDEF', `-DNEEDLOCAL_HOSTNAME_LENGTH=0')
Digital UNIX (formerly DEC OSF/1)
If you are compiling on OSF/1 (DEC Alpha), you must use
-L/usr/shlib (otherwise it core dumps on startup). You may also
need -mld to get the nlist() function, although some versions
apparently don't need this.
Also, the enclosed makefile removed /usr/sbin/smtpd; if you need
it, just create the link to the sendmail binary.
On DEC OSF/1 3.2 or earlier, the MatchGECOS option doesn't work
properly due to a bug in the getpw* routines. If you want to use
this, use -DDEC_OSF_BROKEN_GETPWENT=1. The problem is fixed in 3.2C.
Digital's mail delivery agent, /bin/mail (aka /bin/binmail), will
only preserve the envelope sender in the "From " header if
DefaultUserID is set to daemon. Setting this to mailnull will
cause all mail to have the header "From mailnull ...". To use
a different DefaultUserID, you will need to use a different mail
delivery agent (such as mail.local found in the sendmail
distribution).
On Digital UNIX 4.0 and later, Berkeley DB 1.85 is included with the
operating system and already has the ndbm.o module removed. However,
Digital has modified the original Berkeley DB db.h include file.
This results in the following warning while compiling map.c and udb.c:
cc: Warning: /usr/include/db.h, line 74: The redefinition of the macro
"__signed" conflicts with a current definition because the replacement
lists differ. The redefinition is now in effect.
#define __signed signed
------------------------^
This warning can be ignored.
Digital UNIX's linker checks /usr/ccs/lib/ before /usr/lib/.
If you have installed a new version of BIND in /usr/include
and /usr/lib, you will experience difficulties as Digital ships
libresolv.a in /usr/ccs/lib/ as well. Be sure to replace both
copies of libresolv.a.
IRIX
The header files on SGI IRIX are completely prototyped, and as
a result you can sometimes get some warning messages during
compilation. These can be ignored. There are two errors in
deliver only if you are using gcc, both of the form ``warning:
passing arg N of `execve' from incompatible pointer type''.
Also, if you compile with -DNIS, you will get a complaint
about a declaration of struct dom_binding in a prototype
when compiling map.c; this is not important because the
function being prototyped is not used in that file.
In order to compile sendmail you will have had to install
the developers' option in order to get the necessary include
files.
If you compile with -lmalloc (the fast memory allocator), you may
get warning messages such as the following:
ld32: WARNING 85: definition of _calloc in /usr/lib32/libmalloc.so
preempts that definition in /usr/lib32/mips3/libc.so.
ld32: WARNING 85: definition of _malloc in /usr/lib32/libmalloc.so
preempts that definition in /usr/lib32/mips3/libc.so.
ld32: WARNING 85: definition of _realloc in /usr/lib32/libmalloc.so
preempts that definition in /usr/lib32/mips3/libc.so.
ld32: WARNING 85: definition of _free in /usr/lib32/libmalloc.so
preempts that definition in /usr/lib32/mips3/libc.so.
ld32: WARNING 85: definition of _cfree in /usr/lib32/libmalloc.so
preempts that definition in /usr/lib32/mips3/libc.so.
These are unavoidable and innocuous -- just ignore them.
- According to Dave Sill <de5@ornl.gov>, there is a version of the
- Berkeley DB library patched to run on Irix 6.2 available from
- http://reality.sgi.com/ariel/freeware/#db .
-
IRIX 6.x
If you are using XFS filesystem, avoid using the -32 ABI switch to
the cc compiler if possible.
Broken inet_aton and inet_ntoa on IRIX using gcc: There's
a problem with gcc on IRIX, i.e., gcc can't pass structs
less than 16 bits long unless they are 8 bits; IRIX 6.2 has
some other sized structs. See
http://www.bitmechanic.com/mail-archives/mysql/current/0418.html
This problem seems to be fixed by gcc v2.95.2, gcc v2.8.1
is reported as broken. Check your gcc version for this bug
before installing sendmail.
IRIX 6.4
The IRIX 6.5.4 version of /bin/m4 does not work properly with
sendmail. Either install fw_m4.sw.m4 off the Freeware_May99 CD and
use /usr/freeware/bin/m4 or install and use GNU m4.
NeXT or NEXTSTEP
NEXTSTEP 3.3 and earlier ship with the old DBM library. Also,
Berkeley DB does not currently run on NEXTSTEP.
If you are compiling on NEXTSTEP, you will have to create an
empty file "unistd.h" and create a file "dirent.h" containing:
#include <sys/dir.h>
#define dirent direct
(devtools/OS/NeXT should try to do both of these for you.)
Apparently, there is a bug in getservbyname on Nextstep 3.0
that causes it to fail under some circumstances with the
message "SYSERR: service "smtp" unknown" logged. You should
be able to work around this by including the line:
OOPort=25
in your .cf file.
BSDI (BSD/386) 1.0, NetBSD 0.9, FreeBSD 1.0
The "m4" from BSDI won't handle the config files properly.
I haven't had a chance to test this myself.
The M4 shipped in FreeBSD and NetBSD 0.9 don't handle the config
files properly. One must use either GNU m4 1.1 or the PD-M4
recently posted in comp.os.386bsd.bugs (and maybe others).
NetBSD-current includes the PD-M4 (as stated in the NetBSD file
CHANGES).
FreeBSD 1.0 RELEASE has uname(2) now. Use -DUSEUNAME in order to
use it (look into devtools/OS/FreeBSD). NetBSD-current may have
it too but it has not been verified.
The latest version of Berkeley DB uses a different naming
scheme than the version that is supplied with your release. This
means you will be able to use the current version of Berkeley DB
with sendmail as long you use the new db.h when compiling
sendmail and link it against the new libdb.a or libdb.so. You
should probably keep the original db.h in /usr/include and the
new db.h in /usr/local/include.
4.3BSD
If you are running a "virgin" version of 4.3BSD, you'll have
a very old resolver and be missing some header files. The
header files are simple -- create empty versions and everything
will work fine. For the resolver you should really port a new
version (4.8.3 or later) of the resolver; 4.9 is available on
gatekeeper.DEC.COM in pub/BSD/bind/4.9. If you are really
determined to continue to use your old, buggy version (or as
a shortcut to get sendmail working -- I'm sure you have the
best intentions to port a modern version of BIND), you can
copy ../contrib/oldbind.compat.c into sendmail and add the
following to devtools/Site/site.config.m4:
APPENDDEF(`confOBJADD', `oldbind.compat.o')
OpenBSD (up to 2.9 Release), NetBSD, FreeBSD (up to 4.3-RELEASE)
m4 from *BSD won't handle libsm/Makefile.m4 properly, since the
maximum length for strings is too short. You need to use GNU m4
or patch m4, see for example:
http://FreeBSD.org/cgi/cvsweb.cgi/src/usr.bin/m4/eval.c.diff?r1=1.11&r2=1.12
A/UX
Date: Tue, 12 Oct 1993 18:28:28 -0400 (EDT)
From: "Eric C. Hagberg" <hagberg@med.cornell.edu>
Subject: Fix for A/UX ndbm
I guess this isn't really a sendmail bug, however, it is something
that A/UX users should be aware of when compiling sendmail 8.6.
Apparently, the calls that sendmail is using to the ndbm routines
in A/UX 3.0.x contain calls to "broken" routines, in that the
aliases database will break when it gets "just a little big"
(sorry I don't have exact numbers here, but it broke somewhere
around 20-25 aliases for me.), making all aliases non-functional
after exceeding this point.
What I did was to get the gnu-dbm-1.6 package, compile it, and
then re-compile sendmail with "-lgdbm", "-DNDBM", and using the
ndbm.h header file that comes with the gnu-package. This makes
things behave properly.
[NOTE: see comment above about GDBM]
I suppose porting the New Berkeley DB package is another route,
however, I made a quick attempt at it, and found it difficult
(not easy at least); the gnu-dbm package "configured" and
compiled easily.
[NOTE: Berkeley DB version 2.X runs on A/UX and can be used for
database maps.]
SCO Unix
From: Thomas Essebier <tom@stallion.oz.au>
Organisation: Stallion Technologies Pty Ltd.
It will probably help those who are trying to configure sendmail 8.6.9
to know that if they are on SCO, they had better set
OI-dnsrch
or they will core dump as soon as they try to use the resolver.
i.e., although SCO has _res.dnsrch defined, and is kinda BIND 4.8.3,
it does not inititialise it, nor does it understand 'search' in
/etc/named.boot.
- sigh -
According to SCO, the m4 which ships with UnixWare 2.1.2 is broken.
We recommend installing GNU m4 before attempting to build sendmail.
On some versions a bogus error value is listed if connections
time out (large negative number). To avoid this explicitly set
Timeout.connect to a reasonable value (several minutes).
DG/UX
Doug Anderson <dlander@afterlife.ncsc.mil> has successfully run
V8 on the DG/UX 5.4.2 and 5.4R3.x platforms under heavy usage.
Originally, the DG /bin/mail program wasn't compatible with
the V8 sendmail, since the DG /bin/mail requires the environment
variable "_FORCE_MAIL_LOCAL_=yes" be set. Version 8.7 now includes
this in the environment before invoking the local mailer. Some
have used procmail to avoid this problem in the past. It works
but some have experienced file locking problems with their DG/UX
ports of procmail.
Apollo DomainOS
If you are compiling on Apollo, you will have to create an empty
file "unistd.h" (for DomainOS 10.3 and earlier) and create a file
"dirent.h" containing:
#include <sys/dir.h>
#define dirent direct
(devtools/OS/DomainOS will attempt to do both of these for you.)
HP-UX 8.00
Date: Mon, 24 Jan 1994 13:25:45 +0200
From: Kimmo Suominen <Kimmo.Suominen@lut.fi>
Subject: 8.6.5 w/ HP-UX 8.00 on s300
Just compiled and fought with sendmail 8.6.5 on a HP9000/360 (i.e.,
a series 300 machine) running HP-UX 8.00.
I was getting segmentation fault when delivering to a local user.
With debugging I saw it was faulting when doing _free@libc... *sigh*
It seems the new implementation of malloc on s300 is buggy as of 8.0,
so I tried out the one in -lmalloc (malloc(3X)). With that it seems
to work just dandy.
When linking, you will get the following error:
ld: multiply defined symbol _freespace in file /usr/lib/libmalloc.a
but you can just ignore it. You might want to add this info to the
README file for the future...
Linux
Something broke between versions 0.99.13 and 0.99.14 of Linux: the
flock() system call gives errors. If you are running .14, you must
not use flock. You can do this with -DHASFLOCK=0. We have also
been getting complaints since version 2.4.X was released.
sendmail 8.13 has changed the default locking method to fcntl()
for Linux kernel version 2.4 and later. Be sure to update other
sendmail related programs to match locking techniques (some
examples, besides makemap and mail.local, include procmail, mailx,
mutt, elm, etc).
Around the inclusion of bind-4.9.3 & Linux libc-4.6.20, the
initialization of the _res structure changed. If /etc/hosts.conf
was configured as "hosts, bind" the resolver code could return
"Name server failure" errors. This is supposedly fixed in
later versions of libc (>= 4.6.29?), and later versions of
sendmail (> 8.6.10) try to work around the problem.
Some older versions (< 4.6.20?) of the libc/include files conflict
with sendmail's version of cdefs.h. Deleting sendmail's version
on those systems should be non-harmful, and new versions don't care.
NOTE ON LINUX & BIND: By default, the Makefile generated for Linux
includes header files in /usr/local/include and libraries in
/usr/local/lib. If you've installed BIND on your system, the header
files typically end up in the search path and you need to add
"-lresolv" to the LIBS line in your Makefile. Really old versions
may need to include "-l44bsd" as well (particularly if the link phase
complains about missing strcasecmp, strncasecmp or strpbrk).
Complaints about an undefined reference to `__dn_skipname' in
domain.o are a sure sign that you need to add -lresolv to LIBS.
Newer versions of Linux are basically threaded BIND, so you may or
may not see complaints if you accidentally mix BIND
headers/libraries with virginal libc. If you have BIND headers in
/usr/local/include (resolv.h, etc) you *should* be adding -lresolv
to LIBS. Data structures may change and you'd be asking for a
core dump.
A number of problems have been reported regarding the Linux 2.2.0
kernel. So far, these problems have been tracked down to syslog()
and DNS resolution. We believe the problem is with the poll()
implementation in the Linux 2.2.0 kernel and poll()-aware versions
of glib (at least up to 2.0.111).
glibc
glibc 2.2.1 (and possibly other versions) changed the value of
__RES in resolv.h but failed to actually provide the IPv6 API
changes that the change implied. Therefore, compiling with
-DNETINET6 fails.
Workarounds:
1) Compile without -DNETINET6
2) Build against a real BIND 8.2.2 include/lib tree
3) Wait for glibc to fix it
AIX 4.X
The AIX 4.X linker uses library paths specified during compilation
using -L for run-time shared library searches. Therefore, it is
vital that relative and unsafe directory paths not be using when
compiling sendmail. Because of this danger, by default, compiles
on AIX use the -blibpath option to limit shared libraries to
/usr/lib and /lib. If you need to allow more directories, such as
/usr/local/lib, modify your devtools/Site/site.AIX.4.2.m4,
site.AIX.4.3.m4, and/or site.AIX.4.x.m4 file(s) and set confLDOPTS
appropriately. For example:
define(`confLDOPTS', `-blibpath:/usr/lib:/lib:/usr/local/lib')
Be sure to only add (safe) system directories.
The AIX version of GNU ld also exhibits this problem. If you are
using that version, instead of -blibpath, use its -rpath option.
For example:
gcc -Wl,-rpath /usr/lib -Wl,-rpath /lib -Wl,-rpath /usr/local/lib
AIX 4.X If the test program t-event (and most others) in libsm fails,
check your compiler settings. It seems that the flags -qnoro or
-qnoroconst on some AIX versions trigger a compiler bug. Check
your compiler settings or use cc instead of xlc.
AIX 4.0-4.2, maybe some AIX 4.3 versions
The AIX m4 implements a different mechanism for ifdef which is
inconsistent with other versions of m4. Therefore, it will not
work properly with the sendmail Build architecture or m4
configuration method. To work around this problem, please use
GNU m4 from ftp://ftp.gnu.org/pub/gnu/.
The problem seems to be solved in AIX 4.3.3 at least.
AIX 4.3.3
From: Valdis.Kletnieks@vt.edu
Date: Sun, 02 Jul 2000 03:58:02 -0400
Under AIX 4.3.3, after applying bos.adt.include 4.3.3.12 to close the
BIND 8.2.2 security holes, you can no longer build with -DNETINET6
because they changed the value of __RES in resolv.h but failed to
actually provide the API changes that the change implied.
Workarounds:
1) Compile without -DNETINET6
2) Build against a real BIND 8.2.2 include/lib tree
3) Wait for IBM to fix it
AIX 3.x
This version of sendmail does not support MB, MG, and MR resource
records, which are supported by AIX sendmail.
Several people have reported that the IBM-supplied named returns
fairly random results -- the named should be replaced. It is not
necessary to replace the resolver, which will simplify installation.
A new BIND resolver can be found at http://www.isc.org/isc/.
AIX 3.1.x
The supplied load average code only works correctly for AIX 3.2.x.
For 3.1, use -DLA_TYPE=LA_SUBR and get the latest ``monitor''
package by Jussi Maki <jmaki@hut.fi> from ftp.funet.fi in the
directory pub/unix/AIX/rs6000/monitor-1.12.tar.Z; use the loadavgd
daemon, and the getloadavg subroutine supplied with that package.
If you don't care about load average throttling, just turn off
load average checking using -DLA_TYPE=LA_ZERO.
RISC/os
RISC/os from MIPS is a merged AT&T/Berkeley system. When you
compile on that platform you will get duplicate definitions
on many files. You can ignore these.
System V Release 4 Based Systems
There is a single devtools OS that is intended for all SVR4-based
systems (built from devtools/OS/SVR4). It defines __svr4__,
which is predefined by some compilers. If your compiler already
defines this compile variable, you can delete the definition from
the generated Makefile or create a devtools/Site/site.config.m4
file.
It's been tested on Dell Issue 2.2.

Subject: Notes for DELL SVR4
Eric,
Here are some notes for compiling Sendmail 8.6.4 on DELL SVR4. I ran
across these things when helping out some people who contacted me by
e-mail.
1) Use gcc 2.4.5 (or later?). Dell distributes gcc 2.1 with their
Issue 2.2 Unix. It is too old, and gives you problems with
clock.c, because sigset_t won't get defined in <sys/signal.h>.
This is due to a problematic protection rule in there, and is
fixed with gcc 2.4.5.
2) If you don't use the new Berkeley DB (-DNEWDB), then you need
to add "-lc -lucb" to the libraries to link with. This is because
the -ldbm distributed by Dell needs the bcopy, bcmp and bzero
functions. It is important that you specify both libraries in
the given order to be sure you only get the BSTRING functions
from the UCB library (and not the signal routines etc.).
3) Don't leave out "-lelf" even if compiling with "-lc -lucb".
The UCB library also has another copy of the nlist routines,
but we do want the ones from "-lelf".
If anyone needs a compiled gcc 2.4.5 and/or a ported DB library, they
can use anonymous ftp to fetch them from lut.fi in the /kim directory.
They are copies of what I use on grendel.lut.fi, and offering them
does not imply that I would also support them. I have sent the DB
port for SVR4 back to Keith Bostic for inclusion in the official
distribution, but I haven't heard anything from him as of today.
- gcc-2.4.5-svr4.tar.gz (gcc 2.4.5 and the corresponding libg++)
- db-1.72.tar.gz (with source, objects and a installed copy)
Cheers

ConvexOS 10.1 and below
In order to use the name server, you must create the file
/etc/use_nameserver. If this file does not exist, the call
to res_init() will fail and you will have absolutely no
access to DNS, including MX records.
Amdahl UTS 2.1.5
In order to get UTS to work, you will have to port BIND 4.9.
The vendor's BIND is reported to be ``totally inadequate.''
See sendmail/contrib/AmdahlUTS.patch for the patches necessary
to get BIND 4.9 compiled for UTS.
UnixWare
According to Alexander Kolbasov <sasha@unitech.gamma.ru>,
the m4 on UnixWare 2.0 (still in Beta) will core dump on the
config files. GNU m4 and the m4 from UnixWare 1.x both work.
According to Larry Rosenman <ler@lerami.lerctr.org>:
UnixWare 2.1.[23]'s m4 chokes (not obviously) when
processing the 8.9.0 cf files.
I had a LOCAL_RULE_0 that wound up AFTER the
SBasic_check_rcpt rules using the SCO supplied M4.
GNU M4 works fine.
UNICOS 8.0.3.4
Some people have reported that the -O flag on UNICOS can cause
problems. You may want to turn this off if you have problems
running sendmail. Reported by Jerry G. DeLapp <jgd@acl.lanl.gov>.
Darwin/Mac OS X (10.X.X)
The linker errors produced regarding getopt() and its associated
variables can safely be ignored.
From Mike Zimmerman <zimmy@torrentnet.com>:
From scratch here is what Darwin users need to do to the standard
10.0.0, 10.0.1 install to get sendmail working.
- From http://www.macosx.com/forums/showthread.php?s=6dac0e9e1f3fd118a4870a8a9b559491&threadid=2242:
1. chmod g-w / /private /private/etc
2. Properly set HOSTNAME in /etc/hostconfig to your FQDN:
HOSTNAME=-my.domain.com-
3. Edit /etc/rc.boot:
hostname my.domain.com
domainname domain.com
4. Edit /System/Library/StartupItems/Sendmail/Sendmail:
Remove the "&" after the sendmail command:
/usr/sbin/sendmail -bd -q1h
From Carsten Klapp <carsten.klapp@home.com>:
The easiest workaround is to remove the group-writable permission
for the root directory and the symbolic /etc inherits this
change. While this does fix sendmail, the unfortunate side-effect
is the OS X admin will no longer be able to manipulate icons in the
top level of the Startup disk unless logged into the GUI as the
superuser.
In applying the alternate workaround, care must be taken while
swapping the symlink /etc with the directory /private/etc. In all
likelihood any admin who is concerned with this sendmail error has
enough experience to not accidentally harm anything in the process.
a. Swap the /etc symlink with /private/etc (as superuser):
rm /etc
mv /private/etc /etc
ln -s /etc /private/etc
b. Set / to group unwritable (as superuser):
chmod g-w /
Darwin/Mac OS X (10.1.5)
Apple's upgrade to sendmail 8.12 is incorrectly configured. You
will need to manually fix it up by doing the following:
1. chown smmsp:smmsp /var/spool/clientmqueue
2. chmod 2770 /var/spool/clientmqueue
3. chgrp smmsp /usr/sbin/sendmail
4. chmod g+s /usr/sbin/sendmail
From Daniel J. Luke <dluke@geeklair.net>:
It appears that setting the sendmail.cf property in
/locations/sendmail in NetInfo on Mac OS X 10.1.5 with sendmail
8.12.4 causes 'bad things' to happen.
Specifically sendmail instances that should be getting their config
from /etc/mail/submit.cf don't (so mail/mutt/perl scripts which
open pipes to sendmail stop working as sendmail tries to write to
/var/spool/mqueue and cannot as sendmail is no longer suid root).
Removing the entry from NetInfo fixes this problem.
GNU getopt
I'm told that GNU getopt has a problem in that it gets confused
by the double call. Use the version in conf.c instead.
BIND 4.9.2 and Ultrix
If you are running on Ultrix, be sure you read conf/Info.Ultrix
in the BIND distribution very carefully -- there is information
in there that you need to know in order to avoid errors of the
form:
/lib/libc.a(gethostent.o): sethostent: multiply defined
/lib/libc.a(gethostent.o): endhostent: multiply defined
/lib/libc.a(gethostent.o): gethostbyname: multiply defined
/lib/libc.a(gethostent.o): gethostbyaddr: multiply defined
during the link stage.
BIND 8.X
BIND 8.X returns HOST_NOT_FOUND instead of TRY_AGAIN on temporary
DNS failures when trying to find the hostname associated with an IP
address (gethostbyaddr()). This can cause problems as
$&{client_name} based lookups in class R ($=R) and the access
database won't succeed.
This will be fixed in BIND 8.2.1. For earlier versions, this can
be fixed by making "dns" the last name service queried for host
resolution in /etc/irs.conf:
hosts local continue
hosts dns
strtoul
Some compilers (notably gcc) claim to be ANSI C but do not
include the ANSI-required routine "strtoul". If your compiler
has this problem, you will get an error in srvrsmtp.c on the
code:
# ifdef defined(__STDC__) && !defined(BROKEN_ANSI_LIBRARY)
e->e_msgsize = strtoul(vp, (char **) NULL, 10);
# else
e->e_msgsize = strtol(vp, (char **) NULL, 10);
# endif
You can use -DBROKEN_ANSI_LIBRARY to get around this problem.
Listproc 6.0c
Date: 23 Sep 1995 23:56:07 GMT
Message-ID: <95925101334.~INN-AUMa00187.comp-news@dl.ac.uk>
From: alansz@mellers1.psych.berkeley.edu (Alan Schwartz)
Subject: Listproc 6.0c + Sendmail 8.7 [Helpful hint]
Just upgraded to sendmail 8.7, and discovered that listproc 6.0c
breaks, because it, by default, sends a blank "HELO" rather than
a "HELO hostname" when using the 'system' or 'telnet' mail method.
The fix is to include -DZMAILER in the compilation, which will
cause it to use "HELO hostname" (which Z-mail apparently requires
as well. :)

Please contact Mark Roth for support and questions regarding the

TCP Wrappers
If you are using -DTCPWRAPPERS to get TCP Wrappers support you will
also need to install libwrap.a and modify your site.config.m4 file
or the generated Makefile to include -lwrap in the LIBS line
(make sure that INCDIRS and LIBDIRS point to where the tcpd.h and
libwrap.a can be found).
TCP Wrappers is available at ftp://ftp.porcupine.org/pub/security/.
If you have alternate MX sites for your site, be sure that all of
your MX sites reject the same set of hosts. If not, a bad guy whom
you reject will connect to your site, fail, and move on to the next
MX site, which will accept the mail for you and forward it on to you.
Regular Expressions (MAP_REGEX)
If sendmail linking fails with:
undefined reference to 'regcomp'
or sendmail gives an error about a regular expression with:
pattern-compile-error: : Operation not applicable
Your libc does not include a running version of POSIX-regex. Use
librx or regex.o from the GNU Free Software Foundation,
ftp://ftp.gnu.org/pub/gnu/rx-?.?.tar.gz or
ftp://ftp.gnu.org/pub/gnu/regex-?.?.tar.gz.
You can also use the regex-lib by Henry Spencer,
ftp://ftp.funet.fi/pub/languages/C/spencer/regex.shar.gz
Make sure, your compiler reads regex.h from the distribution,
not from /usr/include, otherwise sendmail will dump a core.
Fedora Core 5, 64 bit version
If the ld stage fails with undefined functions like
__res_querydomain, __dn_expand
then add these lines to devtools/Site/site.config.m4
APPENDDEF(`confLIBDIRS', `-L/usr/lib64')
APPENDDEF(`confINCDIRS', `-I/usr/include/bind9')
and rebuild (sh ./Build -c).
Problem noted by Daniel Krones, solution suggested by
Anthony Howe.
+--------------+
| MANUAL PAGES |
+--------------+
The manual pages have been written against the -man macros, and
should format correctly with any reasonable *roff.
+-----------------+
| DEBUGGING HOOKS |
+-----------------+
As of 8.6.5, sendmail daemons will catch a SIGUSR1 signal and log
some debugging output (logged at LOG_DEBUG severity). The
information dumped is:
* The value of the $j macro.
* A warning if $j is not in the set $=w.
* A list of the open file descriptors.
* The contents of the connection cache.
* If ruleset 89 is defined, it is evaluated and the results printed.
This allows you to get information regarding the runtime state of the
daemon on the fly. This should not be done too frequently, since
the process of rewriting may lose memory which will not be recovered.
Also, ruleset 89 may call non-reentrant routines, so there is a small
non-zero probability that this will cause other problems. It is
really only for debugging serious problems.
A typical formulation of ruleset 89 would be:
R$* $@ $>0 some test address

++---------------------------+
+| SOME NOTES ABOUT THE CODE |
++---------------------------+
+
+Some things are not easy to understand by just reading the source
+code, so this section has some notes which might be interesting for
+those who want to enhance sendmail. These notes are not exhaustive
+but just cover some things which might be interesting.
+
+Address format: sendmail uses a range of 8 bit characters for its
+internal purposes as noted in sendmail.h:
+
+** Special characters in rewriting rules.
+** These are used internally only.
+
+To handle all 8 bit characters, sendmail uses two address formats:
+internal and external -- for details see the comments in cataddr()
+as well as the functions quote_internal_chars() and
+dequote_internal_chars() in libsm/util.c.
+
+These formats are marked in many places with [i] and [x] respectively.
+Some functions only work on one kind of those formats, so it is
+important to mark the strings accordingly. In some cases the marker
+[A] is used to denote that the string format does not matter (which
+is the default) -- this is only used in cases where there might be
+some confusion about any format requirements.

** CHOWNSAFE -- tell if chown is "safe" (executable only by root)
**
** Unfortunately, given that we can't predict other systems on which
** a remote mounted (NFS) filesystem will be mounted, the answer is
** almost always that this is unsafe.
**
** Note also that many operating systems have non-compliant
** implementations of the _POSIX_CHOWN_RESTRICTED variable and the
** fpathconf() routine. According to IEEE 1003.1-1990, if
** _POSIX_CHOWN_RESTRICTED is defined and not equal to -1, then
** no non-root process can give away the file. However, vendors
** don't take NFS into account, so a comfortable value of
** _POSIX_CHOWN_RESTRICTED tells us nothing.
**
** Also, some systems (e.g., IRIX 6.2) return 1 from fpathconf()
** even on files where chown is not restricted. Many systems get
** this wrong on NFS-based filesystems (that is, they say that chown
** is restricted [safe] on NFS filesystems where it may not be, since
** other systems can access the same filesystem and do file giveaway;
** only the NFS server knows for sure!) Hence, it is important to
** get the value of SAFENFSPATHCONF correct -- it should be defined
** _only_ after testing (see test/t_pathconf.c) a system on an unsafe
** NFS-based filesystem to ensure that you can get meaningful results.
** If in doubt, assume unsafe!
**
** You may also need to tweak IS_SAFE_CHOWN -- it should be a
** condition indicating whether the return from pathconf indicates
** that chown is safe (typically either > 0 or >= 0 -- there isn't
** even any agreement about whether a zero return means that a file
** is or is not safe). It defaults to "> 0".
**
** If the parent directory is safe (writable only by owner back
** to the root) then we can relax slightly and trust fpathconf
** in more circumstances. This is really a crock -- if this is an
** NFS mounted filesystem then we really know nothing about the
** underlying implementation. However, most systems pessimize and
** return an error (EINVAL or EOPNOTSUPP) on NFS filesystems, which
** we interpret as unsafe, as we should. Thus, this heuristic gets
** us into a possible problem only on systems that have a broken
** pathconf implementation and which are also poorly configured
** (have :include: files in group- or world-writable directories).
**
** Parameters:
** fd -- the file descriptor to check.
** safedir -- set if the parent directory is safe.
**
** Returns:
** true -- if the chown(2) operation is "safe" -- that is,
** only root can chown the file to an arbitrary user.
** false -- if an arbitrary user can give away a file.

** OutChannel appropriately.
** clrdaemon()
** Close any open files associated with getting
** the connection; this is used when running the queue,
** etc., to avoid having extra file descriptors during
** the queue run and to avoid confusing the network
** code (if it cares).
** makeconnection(host, port, mci, e, enough)
** Make a connection to the named host on the given
** port. Returns zero on success, else an exit status
** describing the error.
** host_map_lookup(map, hbuf, avp, pstat)
** Convert the entry in hbuf into a canonical form.

** it does, a child is created to process it, and the
** parent waits for completion. Return from this
** routine is always in the child. The file pointers

/*
** DELIVER -- Deliver a message to a list of addresses.
**
** This routine delivers to everyone on the same host as the
** user on the head of the list. It is clever about mailers
** that don't handle multiple users. It is NOT guaranteed
** that it will deliver to all these addresses however -- so
** deliver should be called once for each address on the list.
** Deliver tries to be as opportunistic as possible about piggybacking
** messages. Some definitions to make understanding easier follow below.
** Piggybacking occurs when an existing connection to a mail host can
** be used to send the same message to more than one recipient at the
** same time. So "no piggybacking" means one message for one recipient
** per connection. "Intentional piggybacking" happens when the
** recipients' host address (not the mail host address) is used to
** attempt piggybacking. Recipients with the same host address
** have the same mail host. "Coincidental piggybacking" relies on
** piggybacking based on all the mail host addresses in the MX-RR. This
** is "coincidental" in the fact it could not be predicted until the
** MX Resource Records for the hosts were obtained and examined. For
** example (preference order and equivalence is important, not values):
** domain1 IN MX 10 mxhost-A
** IN MX 20 mxhost-B
** domain2 IN MX 4 mxhost-A
** IN MX 8 mxhost-B
** Domain1 and domain2 can piggyback the same message to mxhost-A or
** mxhost-B (if mxhost-A cannot be reached).
** "Coattail piggybacking" relaxes the strictness of "coincidental
** piggybacking" in the hope that most significant (lowest value)
** MX preference host(s) can create more piggybacking. For example
** (again, preference order and equivalence is important, not values):
** domain3 IN MX 100 mxhost-C
** IN MX 100 mxhost-D
** IN MX 200 mxhost-E
** domain4 IN MX 50 mxhost-C
** IN MX 50 mxhost-D
** IN MX 80 mxhost-F
** A message for domain3 and domain4 can piggyback to mxhost-C if mxhost-C
** is available. Same with mxhost-D because in both RR's the preference
** value is the same as mxhost-C, respectively.
** So deliver attempts coattail piggybacking when possible. If the
** first MX preference level hosts cannot be used then the piggybacking
** reverts to coincidental piggybacking. Using the above example you
** cannot deliver to mxhost-F for domain3 regardless of preference value.
** ("Coattail" from "riding on the coattails of your predecessor" meaning
** gaining benefit from a predecessor effort with no or little addition
** effort. The predecessor here being the preceding MX RR).
**
** Parameters:
** e -- the envelope to deliver.
** firstto -- head of the address list to deliver to.
**
** Returns:
** zero -- successfully delivered.
** else -- some failure, see ExitStat for more info.
**
** Side Effects:
** The standard input is passed off to someone.

** This algorithm tries to be smart about wildcard MX records.
** This is hard to do because DNS doesn't tell is if we matched
** against a wildcard or a specific MX.
**
** We always prefer A & CNAME records, since these are presumed
** to be specific.
**
** If we match an MX in one pass and lose it in the next, we use
** the old one. For example, consider an MX matching *.FOO.BAR.COM.
** A hostname bletch.foo.bar.com will match against this MX, but
** will stop matching when we try bletch.bar.com -- so we know
** that bletch.foo.bar.com must have been right. This fails if
** there was also an MX record matching *.BAR.COM, but there are
** some things that just can't be fixed.
**
** Parameters:
** host -- a buffer containing the name of the host.
** This is a value-result parameter.
** hbsize -- the size of the host buffer.
** trymx -- if set, try MX records as well as A and CNAME.
** statp -- pointer to place to store status.
** pttl -- pointer to return TTL (can be NULL).
**
** Returns:
** >0 -- if the host was found.
** 0 -- otherwise.

** The theory is that unhandled exceptions will be 'fatal' class
** exceptions (with an "F:" prefix), such as the out-of-memory
** exception "F:sm.heap". As such, they are handled by exiting
** the process in exactly the same way that xalloc() in Sendmail 8.10
** exits the process when it fails due to lack of memory:
** we call syserr with a message beginning with "!".

.RB [ \-q... ]
.RB [ \-v ]
.SH DESCRIPTION
.B Mailq
prints a summary of the mail messages queued for future delivery.
.PP
-The first line printed for each message
-shows the internal identifier used on this host
-for the message with a possible status character,
+The first line printed for each message
+shows the internal identifier used on this host
+for the message with a possible status character,
the size of the message in bytes,
-the date and time the message was accepted into the queue,
-and the envelope sender of the message.
-The second line shows the error message that caused this message
-to be retained in the queue;
-it will not be present if the message is being processed
-for the first time.
+the date and time the message was accepted into the queue,
+and the envelope sender of the message.
+The second line shows the error message that caused this message
+to be retained in the queue;
+it will not be present if the message is being processed
+for the first time.
The status characters are either
.B *
to indicate the job is being processed;
.B X
to indicate that the load is too high to process the job; and
.B -
to indicate that the job is too young to process.
-The following lines show message recipients,
+The following lines show message recipients,
one per line.
.PP
.B Mailq
is identical to ``sendmail -bp''.
.PP
The relevant options are as follows:
.TP
.B \-Ac
Show the mail submission queue specified in
.I /etc/mail/submit.cf
instead of the MTA queue specified in
.IR /etc/mail/sendmail.cf .
.TP
.B \-qL
Show the "lost" items in the mail queue instead of the normal queue items.
.TP
.B \-qQ
Show the quarantined items in the mail queue instead of the normal queue
items.
.TP
\fB\-q\fR[\fI!\fR]I substr
Limit processed jobs to those containing
.I substr
as a substring of the queue id or not when
.I !
is specified.
.TP
\fB\-q\fR[\fI!\fR]Q substr
Limit processed jobs to quarantined jobs containing
.I substr
as a substring of the quarantine reason or not when
.I !
is specified.
.TP
\fB\-q\fR[\fI!\fR]R substr
Limit processed jobs to those containing
.I substr
as a substring of one of the recipients or not when
.I !
is specified.
.TP
\fB\-q\fR[\fI!\fR]S substr
Limit processed jobs to those containing
.I substr
as a substring of the sender or not when
.I !
is specified.
.TP
.B \-v

and the name of the alias this command expanded from, if any.
Moreover, status messages for each recipient are printed
if available.
.PP
Several sendmail.cf options influence the behavior of the
.B mailq
utility:
The number of items printed per queue group is restricted by
.B MaxQueueRunSize
if that value is set.
The status character
.B *
is not printed for some values of
.B QueueSortOrder,
e.g.,
filename,
random,
modification, and
none,
unless a
.B -q
option is used to limit the processed jobs.
.PP
The
.B mailq
utility exits 0 on success, and >0 if an error occurs.

** MAP.C -- implementations for various map classes.
**
** Each map class implements a series of functions:
**
** bool map_parse(MAP *map, char *args)
** Parse the arguments from the config file. Return true
** if they were ok, false otherwise. Fill in map with the
** values.
**
** char *map_lookup(MAP *map, char *key, char **args, int *pstat)
** Look up the key in the given map. If found, do any
** rewriting the map wants (including "args" if desired)
** and return the value. Set *pstat to the appropriate status
** on error and return NULL. Args will be NULL if called
** from the alias routines, although this should probably
** not be relied upon. It is suggested you call map_rewrite
** to return the results -- it takes care of null termination
** and uses a dynamically expanded buffer as needed.
**
** void map_store(MAP *map, char *key, char *value)
** Store the key:value pair in the map.
**
** bool map_open(MAP *map, int mode)
** Open the map for the indicated mode. Mode should
** be either O_RDONLY or O_RDWR. Return true if it
** was opened successfully, false otherwise. If the open
** failed and the MF_OPTIONAL flag is not set, it should
** also print an error. If the MF_ALIAS bit is set
** and this map class understands the @:@ convention, it
** should call aliaswait() before returning.
**
** void map_close(MAP *map)
** Close the map.
**
** This file also includes the implementation for getcanonname.
** It is currently implemented in a pretty ad-hoc manner; it ought
** to be more properly integrated into the map structure.

** Mail Connection Information (MCI) Caching Module.
**
** There are actually two separate things cached. The first is
** the set of all open connections -- these are stored in a
** (small) list. The second is stored in the symbol table; it
** has the overall status for all hosts, whether or not there
** is a connection open currently.
**
** There should never be too many connections open (since this
** could flood the socket table), nor should a connection be
** allowed to sit idly for too long.
**
** MaxMciCache is the maximum number of open connections that
** will be supported.
**
** MciCacheTimeout is the time (in seconds) that a connection
** is permitted to survive without activity.
**
** We actually try any cached connections by sending a RSET
** before we use them; if the RSET fails we close down the
** connection and reopen it (see smtpprobe()).
**
** The persistent MCI code is donated by Mark Lovell and Paul
** Vixie. It is based on the long term host status code in KJS
** written by Paul but has been adapted by Mark to fit into the
** MCI structure.

** MCI_TRAVERSE_PERSISTENT -- walk persistent status tree
**

** main host status directory if no path is provided.
** Call (*action)(pathname, host) for each file found.
**
** Note: all information is collected in a list before it is processed.
** This may not be the best way to do it, but it seems safest, since
** the file system would be touched while we are attempting to traverse
** the directory tree otherwise (during purges).
**
** Parameters:
** action -- function to call on each node. If returns < 0,
** return immediately.
** pathname -- root of tree. If null, use main host status
** directory.
**
** Returns:
** < 0 -- if any action routine returns a negative value, that
** value is returned.
** 0 -- if we successfully went to completion.
** > 0 -- return status from action()

** MIME support.
**
** I am indebted to John Beck of Hewlett-Packard, who contributed
** his code to me for inclusion. As it turns out, I did not use
** his code since he used a "minimum change" approach that used
** several temp files, and I wanted a "minimum impact" approach
** that would avoid copying. However, looking over his code
** helped me cement my understanding of the problem.
**
** I also looked at, but did not directly use, Nathaniel
** Borenstein's "code.c" module. Again, it functioned as
** a file-to-file translator, which did not fit within my
** design bounds, but it was a useful base for understanding
** the problem.

** We won't be called if we don't have to do a conversion, and

** Parameters:
** mci -- mailer connection information.
** header -- the header for this body part.
** e -- envelope.
** boundaries -- the currently pending message boundaries.
** NULL if we are processing the outer portion.

** level -- recursion level.
**
** Returns:
** An indicator of what terminated the message part:
** MBT_FINAL -- the final boundary
** MBT_INTERMED -- an intermediate boundary
** MBT_NOTSEP -- an end of file
** SM_IO_EOF -- I/O error occurred

** PARSEADDR -- Parse an address
**
** Parses an address and breaks it up into three parts: a
** net to transmit the message on, the host to transmit it
** to, and a user on that host. These are loaded into an
** ADDRESS header with the values squirreled away if necessary.
** The "user" part may not be a real user; the process may
** just reoccur on that machine. For example, on a machine
** with an arpanet connection, the address
** csvax.bill@berkeley
** will break up to a "user" of 'csvax.bill' and a host
** of 'berkeley' -- to be transmitted over the arpanet.
**
** Parameters:
-** addr -- the address to parse.
+** addr -- the address to parse. [i]
** a -- a pointer to the address descriptor buffer.
** If NULL, an address will be created.
** flags -- describe detail for parsing. See RF_ definitions
** in sendmail.h.
** delim -- the character to terminate the address, passed
** to prescan.
** delimptr -- if non-NULL, set to the location of the
** delim character that was found.
** e -- the envelope that will contain this address.
** isrcpt -- true if the address denotes a recipient; false
** indicates a sender.
**
** Returns:
** A pointer to the address descriptor header (`a' if
** `a' is non-NULL).
** NULL on error.

** PRESCAN -- Prescan name and make it canonical
**
** Scans a name and turns it into a set of tokens. This process
** deletes blanks and comments (in parentheses) (if the token type
** for left paren is SPC).
**
** This routine knows about quoted strings and angle brackets.
**
** There are certain subtleties to this routine. The one that
** comes to mind now is that backslashes on the ends of names
** are silently stripped off; this is intentional. The problem
** is that some versions of sndmsg (like at LBL) set the kill
** character to something other than @ when reading addresses;
** so people type "csvax.eric\@berkeley" -- which screws up the
** berknet mailer.
**
** Parameters:
** addr -- the name to chomp.
** delim -- the delimiter for the address, normally
** '\0' or ','; \0 is accepted in any case.
** If '\t' then we are reading the .cf file.
** pvpbuf -- place to put the saved text -- note that
** the pointers are static.
** pvpbsize -- size of pvpbuf.
** delimptr -- if non-NULL, set to the location of the
** terminating delimiter.
** toktab -- if set, a token table to use for parsing.
** If NULL, use the default table.
** ignore -- if true, ignore unbalanced addresses
**
** Returns:
** A pointer to a vector of tokens.
** NULL on error.

/*
** REWRITE -- apply rewrite rules to token vector.
**
** This routine is an ordered production system. Each rewrite
** rule has a LHS (called the pattern) and a RHS (called the
** rewrite); 'rwr' points the the current rewrite rule.
**
** For each rewrite rule, 'avp' points the address vector we
** are trying to match against, and 'pvp' points to the pattern.
** If pvp points to a special match value (MATCHZANY, MATCHANY,
** MATCHONE, MATCHCLASS, MATCHNCLASS) then the address in avp
** matched is saved away in the match vector (pointed to by 'mvp').
**
** When a match between avp & pvp does not match, we try to
** back out. If we back up over MATCHONE, MATCHCLASS, or MATCHNCLASS
** we must also back out the match in mvp. If we reach a
** MATCHANY or MATCHZANY we just extend the match and start
** over again.
**
** When we finally match, we rewrite the address vector
** and try over again.
**
** Parameters:
-** pvp -- pointer to token vector.
+** pvp -- pointer to token vector. [i]
** ruleset -- the ruleset to use for rewriting.
** reclevel -- recursion level (to catch loops).
** e -- the current envelope.
** maxatom -- maximum length of buffer (usually MAXATOM)
**
** Returns:
** A status code. If EX_TEMPFAIL, higher level code should
** attempt recovery.
**
** Side Effects:
** pvp is modified.

** READCF -- read configuration file.
**
** This routine reads the configuration file and builds the internal
** form.
**
** The file is formatted as a sequence of lines, each taken
** atomically. The first character of each line describes how
** the line is to be interpreted. The lines are:
** Dxval Define macro x to have value val.
** Cxword Put word into class x.
** Fxfile [fmt] Read file for lines to put into
** class x. Use scanf string 'fmt'
** or "%s" if not present. Fmt should
** only produce one string-valued result.
** Hname: value Define header with field-name 'name'
** and value as specified; this will be
** macro expanded immediately before
** use.
** Sn Use rewriting set n.
** Rlhs rhs Rewrite addresses that match lhs to
** be rhs.
** Mn arg=val... Define mailer. n is the internal name.
** Args specify mailer parameters.
** Oxvalue Set option x to value.
** O option value Set option (long name) to value.
** Pname=value Set precedence name to value.
** Qn arg=val... Define queue groups. n is the internal name.
** Args specify queue parameters.
** Vversioncode[/vendorcode]
** Version level/vendor name of
** configuration syntax.
** Kmapname mapclass arguments....
** Define keyed lookup of a given class.
** Arguments are class dependent.
** Eenvar=value Set the environment value to the given value.
**
** Parameters:
** cfname -- configuration file name.
** safe -- true if this is the system config file;
** false otherwise.
** e -- the main envelope.
**
** Returns:
** none.
**
** Side Effects:
** Builds several internal tables.

** together with an error message; otherwise, just put it in
** dead.letter in the user's home directory (if he exists on
** this machine).
**
** Parameters:
** e -- the envelope containing the message in error.
** sendbody -- if true, also send back the body of the
** message; otherwise just send the header.
**
** Returns:
** true if savemail panic'ed, (i.e., the data file should
** be preserved by dropenvelope())
**
** Side Effects:
** Saves the letter, by writing or mailing it back to the
** sender, or by putting it in dead.letter in her home
** directory.

will print the contents of the mail queue.
If invoked as
.BR hoststat ,
.B sendmail
will print the persistent host status database.
If invoked as
.BR purgestat ,
.B sendmail
will purge expired entries from the persistent host status database.
If invoked as
.BR smtpd ,
.B sendmail
will act as a daemon, as if the
.B \-bd
option were specified.
.SH NOTES
.B sendmail
often gets blamed for many problems
that are actually the result of other problems,
such as overly permissive modes on directories.
For this reason,
.B sendmail
checks the modes on system directories and files
to determine if they can be trusted.
Although these checks can be turned off
and your system security reduced by setting the
.BR DontBlameSendmail
option,
the permission problems should be fixed.

** adjusted by the message class, the number of recipients, and the
** amount of time the message has been sitting around. This number
** is used to order the queue. Higher values mean LOWER priority.
**
** Each priority class point is worth WkClassFact priority points;
** each recipient is worth WkRecipFact priority points. Each time
** we reprocess a message the priority is adjusted by WkTimeFact.
** WkTimeFact should normally decrease the priority so that jobs
** that have historically failed will be run later; thanks go to
** Jay Lepreau at Utah for pointing out the error in my thinking.

** Bug in OpenSSL (at least up to 0.9.6b):
** From: Lutz.Jaenicke@aet.TU-Cottbus.DE
** Message-ID: <20010723152244.A13122@serv01.aet.tu-cottbus.de>
** To: openssl-users@openssl.org
** Subject: Re: SSL_shutdown() woes (fwd)
**
** The side sending the shutdown alert first will
** not care about the answer of the peer but will
** immediately return with a return value of "0"
** (ssl/s3_lib.c:ssl3_shutdown()). SSL_get_error will evaluate
** the value of "0" and as the shutdown alert of the peer was
** not received (actually, the program did not even wait for
** the answer), an SSL_ERROR_SYSCALL is flagged, because this
** is the default rule in case everything else does not apply.
**
** For your server the problem is different, because it
** receives the shutdown first (setting SSL_RECEIVED_SHUTDOWN),
** then sends its response (SSL_SENT_SHUTDOWN), so for the
** server the shutdown was successful.
**
** As is by know, you would have to call SSL_shutdown() once
** and ignore an SSL_ERROR_SYSCALL returned. Then call
** SSL_shutdown() again to actually get the server's response.
**
** In the last discussion, Bodo Moeller concluded that a
** rewrite of the shutdown code would be necessary, but
** probably with another API, as the change would not be
** compatible to the way it is now. Things do not become
** easier as other programs do not follow the shutdown
** guidelines anyway, so that a lot error conditions and
** compitibility issues would have to be caught.
**
** For now the recommondation is to ignore the error message.

.SH DESCRIPTION
.B Vacation
returns a message,
.IR ~/.vacation.msg
by default, to the sender informing them that you are currently not
reading your mail.
The message is only sent to each sender once per reply interval (see
.B \-r
below).
The intended use is in a
.I .forward
file. For example, your
.I .forward
file might have:
.IP
\eeric, "|/usr/bin/vacation -a allman eric"
.PP
which would send messages to you (assuming your login name was eric) and
reply to any messages for
``eric''
or
``allman''.
.PP
Available options:
.TP
.BI \-a " alias"
Handle messages for
.I alias
in the same manner as those received for the user's
login name.
.TP
.BI \-C " cfpath"
Specify pathname of the sendmail configuration file.
This option is ignored if
.B \-U
is specified.
This option defaults to the standard sendmail configuration file,
located at /etc/mail/sendmail.cf on most systems.
.TP
.B \-d
Send error/debug messages to stderr instead of syslog.
Otherwise, fatal errors, such as calling
.B vacation
with incorrect arguments, or with non-existent
.IR login s,
are logged in the system log file, using
syslog(8).
This should only be used on the command line, not in your
.I .forward
file.
.TP
.BI \-f " filename"
Use
.I filename
as name of the database instead of
.IR ~/.vacation.db
or
.IR ~/.vacation.{dir,pag} .
Unless the
.I filename
starts with / it is relative to ~.
.TP
.B \-i
Initialize the vacation database files. It should be used
before you modify your
.I .forward
file.
This should only be used on the command line, not in your
.I .forward
file.
.TP
.B \-I
Same as
.B \-i
(for backwards compatibility).
This should only be used on the command line, not in your
.I .forward
file.
.TP
.B \-j
Respond to the message regardless of whether the login is listed as
a recipient for the message.
Do not use this flag unless you are sure of the consequences.
For example, this will cause
.i vacation
to reply to mailing list messages which may result in removing
you from the list.
.TP
.B \-l
List the content of the vacation database file including the address
and the associated time of the last auto-response to that address.
This should only be used on the command line, not in your
.I .forward
file.
.TP
.BI \-m " filename"
Use
.I filename
as name of the file containing the message to send instead of
.IR ~/.vacation.msg .
Unless the
.I filename
starts with / it is relative to ~.
.TP
.BI \-R " returnaddr"
Set the reply envelope sender address
.TP
.BI \-r " interval"
Set the reply interval to
.I interval
days. The default is one week.
An interval of ``0'' or
``infinite''
(actually, any non-numeric character) will never send more than
one reply.
The
.B \-r
option should only be used when the vacation database is initialized
(see
.B \-i
above).
.TP
.BI \-s " address"
Use
.I address
instead of the incoming message sender address on the
-.I From
+.I From
line as the recipient for the vacation message.
.TP
.BI \-t " time"
Ignored, available only for compatibility with Sun's
vacation program.
.TP
.B \-U
-Do not attempt to lookup
+Do not attempt to lookup
.I login
in the password file.
The -f and -m options must be used to specify the database and message file
since there is no home directory for the default settings for these options.
.TP
.B \-x
Reads an exclusion list from stdin (one address per line).
Mails coming from an address
in this exclusion list won't get a reply by
.BR vacation .
It is possible to exclude complete domains by specifying
``@domain''
as element of the exclusion list.
This should only be used on the command line, not in your
.I .forward
file.
.TP
.B \-z
Set the sender of the vacation message to
``<>''
instead of the user.
This probably violates the RFCs since vacation messages are
not required by a standards-track RFC to have a null reverse-path.
.PP
.B Vacation
reads the first line from the standard input for a
UNIX
``From''
line to determine the sender.
Sendmail(8)
includes this
``From''
line automatically.
.PP
No message will be sent unless
.I login
(or an
.I alias
supplied using the
.B \-a
option) is part of either the
``To:''
or
``Cc:''
headers of the mail.
No messages from
``???-REQUEST'',
``???-RELAY'',
``???-OWNER'',
``OWNER-???'',
``Postmaster'',
``UUCP'',
``MAILER'',
or
``MAILER-DAEMON''
will be replied to (where these strings are
case insensitive) nor is a notification sent if a
``Precedence: bulk''
or
``Precedence: junk''
line is included in the mail headers.
The people who have sent you messages are maintained as a
db(3)
or
dbm(3)
database in the file
.I .vacation.db
or
.I .vacation.{dir,pag}
in your home directory.
.PP
.B Vacation
expects a file
.IR .vacation.msg ,
in your home directory, containing a message to be sent back to each
sender. It should be an entire message (including headers). For
example, it might contain:
.IP
.nf
From: eric@CS.Berkeley.EDU (Eric Allman)
Subject: I am on vacation
Delivered-By-The-Graces-Of: The Vacation program
Precedence: bulk
I am on vacation until July 22. If you have something urgent,
please contact Keith Bostic <bostic@CS.Berkeley.EDU>.
