Configuring Postfix for Incoming Connections Using a FreeBSD Jail

12 Nov2006

When I configured FreeBSD jails, I added this line to /usr/local/etc/postfix/main.cf:

inet_interfaces configuration line

This stops postfix from listening on all network interfaces on the machine, and means that jail processes can run separate postfix instances.

However, I didn't use this machine to receive incoming mail at first, only for sending mail out through a relay (mostly from web applications).

I want to start using this machine as my main mail server, and also wanted to have bugmail@workingsoftware.com.au deliver mail to the Bugzilla mail interface script, but even though postfix was listening on port 25, as shown by this command and the corresponding output:

lsof command showing postfix listening on port 25

I was unable to connect on port 25. I couldn't figure out how to fix it, but adding this line to /usr/local/etc/postfix/master.cf seems to work:

smtpd config line

and I can now see this process listening on port 25:

lsof command showing new smtpd process

telnet socata.scoastnet.com.au 25 now works also, so I assume this has done the trick.
