When you are running multiples vservers on a same physical box, it may be usefull to allow box daemons (like cron) to send mail for debugging purpose or just seeing if a problem occurs.

Debian Gnu/Linux provide 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, witch is here the most useful don't work out of box. (postfix start withouth any message, but doesn't appear in proces list (ps)).

Few fix are needed for postfix run good:


1) Add a line in /etc/hosts with:

  1. nano /etc/hosts nameofhost

You can also add : localhost

(the "localhost" hostname is used by some other daemons and point normaly to

2) Modify postfix configuration:

  1. nano /etc/postfix/


inet_interfaces = loopback-only


inet_interfaces = name_of_host_entered_in__etc_hosts


inet_interfaces = localhost

3) Restart postfix with /etc/init.d/postfix restart and check it run with "ps"
