А когда устанавливаешь Postfix в конце установки вот такое предупреждение.To enable postfix rcNG startup script please add postfix_enable="YES" in
your rc.conf
If you not need sendmail anymore, please add in your rc.conf:
sendmail_enable="NO"
sendmail_submit_enable="NO"
sendmail_outbound_enable="NO"
sendmail_msp_queue_enable="NO"
And you can disable some sendmail specific daily maintenance routines in your
/etc/periodic.conf file:
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 /usr/local/etc/sasldb* file(s) readable by group mail (this should
be the default for new installs).
If you are upgrading from postfix version prior to 2.0, please see the README
files for recommended changes to your configuration.
Еще /etc/make.conf можно подправить на предмет sendmail, например
NO_SENDMAIL=
и другие, но я сам непробовал пока, времени небыло, прежде чем делать на рабочей машине надо бы испытать на резервной, вот с этим как раз пока напряг.
