3rd party products to produce a Catch-All mailbox

[Bob]

Does anyone know of any 3rd party products that will allow *@mydomain.com to be forwarded to a certain mailbox (maybe info@mydomain.com) so emails sent to a non-existant mailbox will be dumped into a mailbox (and not generate an NDR)? Exchange does not natively support this... so I'm searching for a 3rd party add-on that will allow this to happen.

Thanks!
Bob
