Hi Scott. You replied to me directly rather than to the list. It's
customary to keep such conversations on list until they become OT.

I've not had experience with Zimbra directly but it will do one of the
following:
1.) Tell the connecting mail server that no such account exists. At
which time the sending server will send a bounce back to the sender of
the message and you'll never received it
2.) Accept the message, then realise it doesn't have an account, and
send a bounce back to the sender it's self.
Either way you wont get the mail. Taking this from a different angle,
how about if you continue to allow the mail to be delivered to Exim, and
then you just get Exim to shunt off a second copy of the message to Zimbra?
If that is acceptable, what you want to do is set up a manualroute
router in Exim pointing to Zimbra, and mark it as "unseen". Check out
the docs on
http://www.exim.org/ and let us know if you need further help.
