A better idea is to just reject it at connection time. One of the fundamental principles of mail system defense is that you *will* make mistakes, so you should make them definitively, make them consistently, make them as early as possible, and make them noisily. For example: silently discarding an already-accepted message is horrible. Rejecting it with a 550 and appropriate error message during the delivery attempt is excellent. It's better for everyone because it creates log entries that can be found, read, and understood on both sides and thus makes it possible to locate and correct a mistake -- if in fact it *is* a mistake. ---rsk _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
