I'm migrating to Zimbra from good ol' postfix. Right now my postfix is configured to accept all email to the domain, and put it into a specific user's mailbox. So for example anything@mydomain.com goes into bill@mydomain.com - I do this on purpose.

I tried searching for this, but I can't find it in the Wiki or the forums. Is there an easy way to do this that I am missing? I have thousands of known aliases, and I'm not able to enter them all in as aliases!
