[Please remove python-dev from followups, I'm sure most of those folks
don't care about this... -BAW]
MM-Devers: on python-dev there's been some discussion about the
Reply-to: munging that you can select on Mailman lists. Say you've
got a python-checkins list that receives CVS log messages
automatically. But you don't want discussions about the changes on
python-checkins, you want them on python-dev.
How can Mailman set up the headers on outgoing messages to get this
behavior? It can't. So it fakes it by setting Reply-to: to the
address of the discussion list. We now join our conversation already
in progress...

It looks like VM/Emacs doesn't (which is what I use), but I'm sure
that'd be easy to add. I would be most interested to know what
Outlook and NS do with it.
However Mail-Followup-To: isn't in any RFC that I can find, not even
2076. It can be found in a discussion by Dan Bernstein[1], but that
document specifically says that list managers should /not/ set it
because this defeats the intended purpose. I agree - given Dan's
recommendation.
So there is clearly no header that will support the functionality we
want. And all this crud has been debated ad-nauseum in several
working groups, MUA forums, etc. with no agreement. I almost hesitate
even bringing it up here. Few of the discussions that I've read (in a
morning's worth of archive surfing) even mention the situation we're
trying to address.
One potential solution for Mailman might be to lie about the To:
address. So in the above scenario, the message would have a To: field
set to python-dev even though the message would actually be sent to
the python-checkins membership. An elaboration on that would be to
set Resent-To: to python-checkins. But those are all hacks, nearly as
disgusting as what Mailman currently does.
