Redirect emails to not existing recipients to a specific User

Is there a way to redirect incoming emails to recipients who don't exist on Exchange to a specific mailbox? I have a migration scenarion with several thousands of users. To be sure that no emails get lost if we miss to migrate some users, I would like all incoming emails adressed to our domain to not existing users on the Exchange Server to be rerouted to a specific mailbox.

Thanks for help.

On the website they say "CSCatchAll adds a catch-all mailbox capability to Microsoft Exchange" 2000 and 2003 server installations". Does this work for Exchange 2007 as well?
Dont know if it works on 2007.

You can try to type this in google

"catch all" exchange 2007

That will give you some hints
