relay access denyed in postfix using virtual alias maps

[devnill]

I'm trying to set up postfix to relay mail using virtual_alias maps but they are getting bounced. I've already checked to make sure the domains are in my virtual_alias_domains table but everything seems to be set correctly. How can I diagnose this issue?

Below is information that might be of help:

Are there any other errors in your mail log? What's in /usr/local/etc/postfix/virtusertable?
