About the only way to do that is to add a Return-Path header to the e-mail so if it bounces the Return-Path address gets the bounce message. There is no way to do it more or less real-time because some SMTP servers will try to send the message to the recipient for sometimes five days before generating a bounce. -- Leif (TB lists moderator and fellow end user).
