You don't want to send rejects to more than one address 'cos you then have a simple message multiplier; send one message, generate two bounces; the mail server will be doubling the back-scatter problem! Anyway, the SMTP server should send the delivery failure to the envelope address, which may be different to both the From and Reply-To addresses. -- rgds Stephen
