Description

  • update to 3.3-20170613

Changelog:
20170505

Workaround for a current problem where some destination
announces primarily IPv6 MX addresses, the smtp_address_limit
eliminates most or all IPv4 addresses, and the destination
is not reachable over IPv6. This workaround is enabled with
"smtp_balance_mx_inet_protocols = yes", which is the default.
Files: smtp/smtp.c, smtp/smtp_params.c, smtp/smtp_addr.c,
global/mail_params.h, proto/postconf.proto.

20170506

A last-minute cosmetic fix had introduced a bug in
smtp/smtp_addr.c.

20170512

Bugfix (introduced: Postfix 2.0): the MIME nesting level
counter was not initialized (i.e. left at the memory fill
pattern 0xffffffff which equals -1). This broke unit tests
with a different memory allocator. Changing the value to
zero would break backwards compatibility (reject mail that
was previously not rejected). Files: global/mime_state.c.

20170531

Bugfix (introduced: Postfix 3.2): after the table lookup
overhaul, the check_sender_access and check_recipient_access
features ignored the parent_domain_matches_subdomains
setting. Reported by Henrik Larsson. File: smtpd/smtpd_check.c.

Workaround (introduced: Postfix 3.2): mail_addr_find() logs
a warning that it does not support both parent-domain and
dot-parent-domain style lookups in the same call.  File:
global/mail_addr_find.c

20170610

Workaround (introduced: Postfix 3.0 20140718): prevent MIME
downgrade of Postfix-generated message/delivery-status.
It's supposed to be 7bit, therefore quoted-printable encoding
is not expected. Problem reported by Griff. File:
bounce/bounce_notify_util.c.

Documentation: indicate that the transport_mumble parameters
are implemented by the queue manager, not by delivery agents.
Files: mantools/postlink, local/local.c, pipe/pipe.c,
*qmgr/qmgr.c, smtp/smtp.c, virtual/virtual.c.

20170611

Security: Berkeley DB 2 and later try to read settings from
a file DB_CONFIG in the current directory.  This undocumented
feature may introduce undisclosed vulnerabilities resulting in
privilege escalation with Postfix set-gid programs (postdrop,
postqueue) before they chdir to the Postfix queue directory,
and with the postmap and postalias commands depending on whether
the user's current directory is writable by other users. This
fix does not change Postfix behavior for Berkeley DB < 3.
File: util/dict_db.c.
