To elaborate a bit. RFC 5322 says The "From:" field specifies the author(s) of the message, that is, the mailbox(es) of the person(s) or system(s) responsible for the writing of the message. The "Sender:" field specifies the mailbox of the agent responsible for the actual transmission of the message. For example, if a secretary were to send a message for another person, the mailbox of the secretary would appear in the "Sender:" field and the mailbox of the actual author would appear in the "From:" field. In that sense, many of us think that the person who wrote the post is still the author even if the list made a few simple changes that didn't alter the basic text of the original message while the list is a Sender: That's why we believe that Munge From is non-compliant. You may think that the list is in fact "the person(s) or system(s) responsible for the writing of the message", but many people don't agree. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
