Wouldn't you know that as soon as I posted this I was sitting here sweating over my main.cf and saw that the mydestination line didn't include proper domains...

Figured I'd leave this in here in case someone else has a similar issue.

OK, I have spent 6 hours reading hundreds of threads around the web with people having this issue, but none of those fixes helped solve my issue...

Debian Lenny

Virtual server can sent emails but can not receive. I get the following error:

(expanded from <scott@virtualserver.com>):
User unknown in virtual alias table

This is different than a problem I had with a similar User unknown in virtual alias table that I encountered before in that the email address it is seeing is scott.virtualserver@primarydomain.org instead of scott@virtualserver.com

Any thoughts on where I misconfigured?
