[net.mail.headers] multiple senders ?

POSTEL@USC-ISIF.ARPA (06/05/84)

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.
