Hello, I followed your Howto "Set Up Postfix For Relaying Emails Through Another Mailserver", and works fine. Thank you very much for this tutorial. Problem: I am currently hosting 2 domains and both are using the same Relay server (gmail) . Question: Is there a way to configure postfix so each domain i host, use a different Relay Mailserver? Thanks.
Why do you want to do this? This link might help you: http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps
