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 -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
