This is the problem. There isn't any way to reliably distinguish a fatal bounce from an innocent auto-response given the huge variety of auto-responders and MTAs out there. What you are looking for is a way to refuse mail from an address that can't be replied to. This can only be done reliably in the MTA. Refusing mail from bogus domains gets you part of the way there, but not all the way because spammers often combine fake usernames with valid domains. I just noticed that the most recent Postfix snapshot has a feature that verifies a sender's existence (via reverse SMTP) before accepting a message. This would get you what you want in a reliable manner. _________________________________________________ tmda-workers mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-workers
