i have decided to have a separate mail server for my app. When i use php to send email, postfix sends successfully to other domains(gmail.com etc), but uses local relay for the addresses hosted on my mail server. The MX record works fine. All i need is to get the local addresses out. I dont know where to start. Please, help.

I believe you're looking for the relayhost configuration option. In your /etc/postfix/main.cf file, enter a line containing relayhost = mail.foo.com. This should make all outgoing mail go through mail.foo.com.

What does that do, why should it work? –  Chris S Jan 4 '13 at 16:42
