        I've tried different situations for the From: header, and some of them
look suspicious to me:

1/ From is in message-required-mail-headers.
   When I edit a message, I see a line with "Sender: verna@metheny.enst.fr"
   This is not my email address, but the machine on which I'm working.

        a/ I send the message as-is.
           There, I get a proper From: line and a Sender: identical to From:

        b/ I manually add a From: line (say foo@bar.baz).
           There, I get _two_ From: lines. The one I set, and the normal one.
           There's also a Sender line like in the preceding case.

        c/ I manually add a From: line, but I also remove the Sender: line.
           There, the situation is as in b/.


2/ From is _not_ present in message-required-mail-headers.
   When I edit a message, neither From: nor Sender: is there at startup.

        a/ I send the message as-is.
           There, I get a good From: line, and no Sender:.

        b/ I insert manually a From: line (say, foo@bar.baz)
           There, I receive the From: line, and a Sender: with my usual
           address this time.


2-a and 2-b looks ok to me.
1-a looks redundant,
1-b and 1-c look bogus.

        Comments ? Am I wrong ? In particular, I'd like to know, if I just
want another From: address temporarily for just one message, I should in the
1-a case right ?

        I'd also like to try this on a newsgroup, but I don't want to spam.
