Exchange 5.5 mail forwarding

Hi again. The new router and NAT are working great and our MX record has finally propagated. But... I have a question.

How can I forward all incoming email that is not addressed correctly (email address spelled wrong or the user name spelled wrong) to the administrator mailbox?

Currently the system is set to notify myself of all outgoing and incoming failures but I'd like to put in place some sort of filter to route all non-deliverable email to my inbox (I'm listed as an administrator).

Any suggestions are apreciated.

Thanks,
J.
