Do you mean sendmail reject delivery of all mail when the receipent
doesn't appear in the virtualusertable?

If so, try putting a catch-all address in the virtusertable:

@domain.com	error:nouser 550 User unknown

Once you've done this you will have to add all the users that should
receive mail at that address or they too will be rejected.

If you want sendmail to reject non-existent users per domain, you obviously
have to tell it which users exist in each domain. This is done by
enumerating
them in the virtusertable and adding the catch-all to indicate that all
users
are explicitly listed there.

If you have a lot of domains on that machine,that can hardly be a problem
