that's correct.

See below.

Yes. In fact there are several ways. We're using sendmail's virtusertable 
feature. You need an entry for each user. We've added the following entry:

@uni-koeln.de   error:5.1.1:550 User unknown

So all addresses not explicitly listed will be handled as errors. You could 
just as well redirect all mail to unknown users to a specific catch-all 
user.

Another approach is this one:

Take your pick ...
