Judging from all of the other responses, I guess I'm missing something, because this is my response: Do not accept then bounce mail for non-existent users. You should be REJECTING them, and let the *originating* server generate the bounce (for typo's and such)... If you are bouncing mail destined for non-existent users then you are engaging in back-scatter. -- Best regards, Charles
