I'm not sure if this would work, but I believe you can put:

name@xxxxxxxxxxxxxx[TAB]error:nouser No such user here
in the custom section of virtualusertable

If not, you would need to bounce it with Procmail which isn't really a
bounce but an auto reply. The other option is to create a username and
put the old email alias in with a vacation reply to let people know that
address is no longer valid.

I prefer to discourage catch-alls and instead set up necessary email
aliases so everything else bounces and you don't get thousands of spams
via a dictionary attack.
