Point taken. But in case there is one--I want to delete it. I've seen mails to lists with From in it. > Return-Path: is a an RFC2821 message header, but it should only be added > to messages for final delivery (as a permanent record of the envelope > sender). It shouldn't be seen "on the wire" during SMTP. mlmmj might see > it, but should delete it.
