External mailserver

[grungy]

I want to setup a domain in Omega that uses a external mail server, too.

I first tough that I need only to setup the MX DNS record but I see that this is not the case because as I can see, correct me if I'm wrong, Omega adds the domain to Postfix and postfix thinks it should handle the domain, the problem:

Code:

Apr 12 10:27:10 ns1 postfix/pickup[16337]: EBE711AE2B9A: uid=33 from=<www-data>
Apr 12 10:27:10 ns1 postfix/cleanup[20036]: EBE711AE2B9A: message-id=<638f17e3df0efd9c2d87a7e34390d21e@domain.tld>
Apr 12 10:27:10 ns1 postfix/qmgr[26559]: EBE711AE2B9A: from=<www-data@tophosting.ws>, size=445, nrcpt=1 (queue active)
Apr 12 10:27:10 ns1 postfix/virtual[20038]: EBE711AE2B9A: to=<username@domain.tld>, relay=virtual, delay=0, status=bounced (unknown user: "username@domain.tld")

This is as I understand sent using a php script from the Omega server itself....
