Postfix Port

A menu will appear when you make this port. Select the options Cyrus SASL v2 and Berkeley DB4.3. The script will ask whether you want to add the postfix user to the mail group and whether you want to activate Postfix in /etc/mail/mailer.conf. Answer yes to both.

# cd /usr/ports/mail/postfix
# make install clean
# rehash

Enable Postfix at startup by adding the following to your /etc/rc/conf:

sendmail_enable="NONE"
sendmail_flags="-bd"
sendmail_pidfile="/var/spool/postfix/pid/master.pid"
sendmail_outbound_enable="NO"
sendmail_submit_enable="NO"
sendmail_msp_queue_enable="NO"

Also create a symbolic link in the startup folder so that Postfix will start when the system boots:

# cd /usr/local/etc/rc.d
# ln -s /usr/local/sbin/postfix postfix.sh

Then 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"

With Postfix configured, create a needed file called alias.db, and then start it.

# newaliases
# ls -l /etc/aliases.db
# postmap /usr/local/etc/postfix/virtual
# postfix start

Although the setup described in this article does not use this file, Postfix looks for it anyway. You may need this file depending on your future needs.

To test whether Postfix is running:

telnet localhost 25
You should see a prompt
Trying 127.0.0.1...
Connected to < your host name >
Escape character is '^]'.
quit

There is one final file to edit, /usr/local/etc/postfix main.cf. Change the entire main.cf as follows. (Again, bracketed numbers refer to footnotes, so remove them.)

virtual_transport       = lmtp:unix:/var/imap/socket/lmtp
virtual_mailbox_domains = domain1, domain2 [2]
virtual_alias_maps      = hash:/usr/local/etc/postfix/virtual

[1] The primary domain for email purposes.

[2] A list of all domains you plan to manage, including your primary domain.
