Specifically the kind where all list emails come from the the same address, with the sender in Reply-To?
It seems like this /should/ be the way it works. Isn't that what Reply-To is for?
Do some email clients still mess it up? If they do, wouldn't it make sense to just send them a bounce notice and tell them to clean up their act?
See https://gitlab.com/mailman/mailman/-/blob/master/src/mailman/handlers/dmarc.... for what we say about this.
I'm guessing that your concern is that a reply as opposed to reply all should go to the poster and not to the list. I think that will be
the case with most mainstream MUAs, but RFC 5322 is somewhat wishy-washy
about that saying only "When the "Reply-To:" field is present, it
indicates the address(es) to which the author of the message suggests
that replies be sent."
