I'm filtering based on whether or not it actually came from a mailing
list.  The mail the list relays to me will have these list headers,
and any new lists will appear as I subscribe.  Mail sent directly to
me via To: or Cc: or Bcc: will appear in my normal spool.

You already listed the reason why I do not filter based on subject
lines.  Too many people take conversations off-list without changing
the list tag to [OFF-LIST] in the subject.

	Mailman is welcome to support whatever broken features it
wants.  Hell, it allows you to obliterate someone's Reply-To header
and impose the list's on top of it.  At least this thing you refer to
is per-subscriber and not per-list.  I think the Reply-To munging
would be appropriate if it were done per-subscriber (since it is, in
fact, a UI issue and thus should be in the control of the individual
