I've put back the Sender: line now. Hopefully. But if there already is one it
won't be replaced, so you can't count on it being there, making it kinda
pointless... Aw crap. Well, once again, you should use List-ID to sort your
list mail.
Reading RFC 2822 §3.6.2, "Sender:" is an "originator field", as are "From:"
and "Reply-To:". They "indicate the mailbox(es) of the source of the
message". As an example they give a secretary who types and sends a message
for some other person. Mailman just adds a footer to incoming messages and
distribute them to the list subscribers. The messages are still substantially
the same, so you can't really say that Mailman is an originator. It
originates confirmation and notification messages though.
Resent-From is possibly a more semantically correct header field to add.
