dmarc_moderation_action=1 is munge_from which means the from will be set
to the list address if dmarc mitigations are applied which will be the
case for cmu.edu addresses if dmarc_quarantine_moderation_action and
dmarc_none_moderation_action are both yes. This will change the From:
which list2 sees to, e.g. in your case)

From: Gretchen R Beck via List 1 <list1@...>

list1@... is not in list2's accept_these_nonmembers. Putting it there
will help if this is the issue.
