This happened to me and the problem was that, in my virtual hosting environment, I had a catch-all virtmap setup for the domain I wanted to use that went to a non-existent user. I placed that virtmap on my server because I wanted mail that wasn't addressed properly to be returned to the sender.
When an e-mail goes into a server with virtual hosts, the virtmaps (virtusertable) file is read first, then the aliases. So make sure you don't have a catchall set up that returns mail or stops it from getting to your alias entries. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jon Carnes Sent: Saturday, March 06, 2004 3:59 PM To: ??

This sounds like a classic case of the aliases not being added.
