 To use postfix instead of sendmail:
   - clear sendmail queue and stop the sendmail daemons
 
 Run the following commands to enable postfix during startup:
   - sysrc postfix_enable="YES"
   - sysrc sendmail_enable="NONE"
 
 If postfix is *not* already activated in %%MC_PREFIX%%/etc/mail/mailer.conf
   - mv %%MC_PREFIX%%/etc/mail/mailer.conf %%MC_PREFIX%%/etc/mail/mailer.conf.old
   - install -m 0644 %%DATADIR%%/mailer.conf.postfix %%MC_PREFIX%%/etc/mail/mailer.conf
 
 Disable sendmail(8) specific tasks,
 add the following lines to /etc/periodic.conf(.local):
   daily_clean_hoststat_enable="NO"
   daily_status_mail_rejects_enable="NO"
   daily_status_include_submit_mailq="NO"
   daily_submit_queuerun="NO"
 
 If you are using SASL, you need to make sure that postfix has access to read
 the sasldb file.  This is accomplished by adding postfix to group mail and
 making the %%PREFIX%%/etc/sasldb* file(s) readable by group mail (this should
 be the default for new installs).
