I am managing a server which mainly deals in relaying mail using virtual alias maps. For some reason unknown to me email that goes through these maps are getting bounced. I've checked to make sure the domains are in my virtual_alias_domains table but they are still bouncing. I've consulted the postfix site but everything seems to be set correctly. How can I diagnose this issue?
Below is information that might be of help:
