Relay access denied

Sziasztok!

A következő gondom van:
Debian rendszeren levelező szervert telepítettünk (postfix, courier), ami működött is. Át kellett nevezni a levelező szervert és azóta nem fogad leveleket se küldeni tudunk.
Érdekes, hogy azok a domainek, amik nincsenek a szerverre irányítva, csak az MX record-juk működnek.
A következő hibát kapjuk:

Reporting-MTA: dns; mail00d.mail.t-online.hu
X-Postfix-Queue-ID: 3VDrc11ffwz173X1
X-Postfix-Sender: rfc822; xxxxx@gmail.com

Final-Recipient: rfc822; info@xxxx.hu
Original-Recipient: rfc822;info@xxxx.hu
Action: failed
Status: 5.7.1
Remote-MTA: dns; mail.rackhost.hu
Diagnostic-Code: smtp; 554 5.7.1 : Relay access denied

Mi lehet a hiba? A potfix main.cf-je:
