Good day, I have been trying to add another relay domain to my spam snake which is delivering mail to my exchange server for my main domain. Unfortunately I only see this in the log: Diagnostic-Code: X-Postfix; mail for xxx.com loops back to myself Where should i be adding the domain? I have configured my relay_receipients to get addresses from my AD and that works just great but when I run the sql select to check the domains it is empty. Could that be the issue? mysql> select concat(address, ' ', 'OK') 'domain' from user_addresses where user_addresses.address='%s' and user_addresses.enabled='1'; Empty set (0.00 sec) Thank you!
