Hostname on OpenVZ containers

[SamTzu]

I'm having some problems with Postfix because postifx gets it's domain name from this line...

mydestination = $myhostname, localhost.$mydomain, localhost

Because OpenVZ containers normally only place the hostname on /etc/hostname file this creates problems on every reboot.
Postfix shows the server as server1.localdomain.


Any suggestions how to solve this problem?

At the beginning of the file: /etc/postfix/main.cf, insert the following:

myhostname = myhost.mydomain.com

where the actual FQDN value in bold italics above should be your container's real one.
