Synopsis
When you are running multiples vservers on a same physical box, it may be useful to allow box daemons (like cron) to send mail for debugging purpose or just seeing if a problem occurs. Debian GNU/Linux provides a good way to configure packages like Postfix. You can use
# dpkg-reconfigure postfix
to start configuring (this script is also called when installing Postfix)
The problem is that, the local-only mode (which in this instance is the most useful) doesn't work 'out of the box' (Postfix starts without any messages, but doesn't appear in process list (ps)).
A few fixes are needed for Postfix to run properly:
/etc/hosts additions
Add a line in /etc/hosts with:
nano /etc/hosts
ip.of.the.host nameofhost
You can also add:
ip.of.the.host localhost
(the "localhost" hostname is used by some other daemons and normally points to 127.0.0.1.)
Modify postfix configuration
# nano /etc/postfix/main.cf
Replace
inet_interfaces = loopback-only
with
inet_interfaces = name_of_host_entered_in__etc_hosts
or
inet_interfaces = localhost
Restart Postfix
Restart Postfix with
/etc/init.d/postfix restart
and check it run with "ps".
That's all folks ;)
