In the RFC 822 world a message has one sender. The "from" is the author or authors of the message. The "sender" is the clerk that pushed the final button that sent the message. When a message is forwarded it is really a new message and should have (at least) additional header fields added to indicate who did the forwarding and when (resent-sender, resent-from, resent-date). If two different people (say, Fred and Sam) get copies of a message and both forward it to a third person (say, Joe), then the third person (Joe) will get two copies -- but, he (Joe) will be able to see when and by whom each copy was forwarded. --jon. -------
