if you have just a few users, you can set up smtpd_restriction_classes for each user, but that quickly gets out of hand. Some folks reject their own domain from an "outside" unauthenticated connection, but that's guaranteed to reject some amount of legit mail. You get to decide if "some amount" is acceptable at your site. -- Noel Jones
