from_is_list is Munge From anonymous_list is No

dmarc_moderation_action is Munge From dmarc_quarantine_moderation_action is Yes
with the above, your list should be munging the From: on all outgoing messages because from_is_list is Munge From. The dmarc_moderation_action of Munge From is redundant in this case. It would serve to munge the
From only on messages originally from domains with DMARC p=reject or quarantine if from_is_list were No.
So the first question is what does the From: look like on messages from the list. Is it
From: Jane User <user@yahoo.com>
(which is not what it should be - something is wrong) or is it
From: Jane User via LISTNAME list <listname@mailman.host>
which is what it should be. If it is the latter, and your mailman.host does not publish a DMARC policy, then Yahoo is not rejecting the mail for DMARC, but for some other unknown to me reason, but Mailman is doing what it can.
If the From: is not munged, then there is a Mailman issue we can investigate. So which is it?
