What is the intent of the restriction?  Are you trying to get the
users to use "reply to author" by punishing them with a black hole if
they don't, and then set Reply-To to list-post so that nobody ever
gets a personal reply?  Or is this intended to prevent people from
including 3rd parties in the OP (of course, you can't -- they can
always BCC and you'll never know)?

I suppose your users would get upset if you used
dmarc_moderation_action = 'Wrap Message' instead of whichever_option =
'Mung From'?

Given Mark's reply, probably you'll need use a custom Handler,
whatever the requirements.  Is that acceptable (ie, you have the
necessary accesses)?  N.B. It's possible to restrict use of Handlers
to particular lists by giving them list-specific pipelines.
