With Mailman's DMARC mitigations, if the sender's address is removed
from the From: header, it is always in either Reply-To: or Cc:. Even if
a user's MUA doesn't correctly address a Reply, it seems to me that it's
just as easy to copy/paste the address from the Reply-To: or Cc: header
of the original post as it is to copy/paste it from somewhere else in
the message. What am I missing?
Also, in my experience, users tend not to look at how their reply is
addressed in the first place and don't even notice that it is addressed
say to the list rather than the poster.
I think the appropriate solution is for users to use compliant MUAs that
will honor Reply-To:, although I understand that that's a lot easier for
me to say than it is to get users to actually do it.
All that said, if you really want it, it's a one line patch to add a
'sender' replacement to msg_header and/or msg_footer (watch out for
wrapped lines).
