This should have no effect on Mailman 2.1.18+ installations since the
deprecated 'from_is_list' mitigations apply to all list mail and the
recommended 'dmarc_moderation_action' mitigations already check the
From: domain's DMARC policy.

There is one bug at <https://bugs.launchpad.net/mailman/+bug/1549420>
that is fixed in 2.1.21. Prior to that, if a message was From: a
subdomain of an 'organizational domain' and the subdomain didn't publish
a DMARC policy, the organizational domain wasn't checked for
dmarc_moderation_action. Beginning in 2.1.21 it is checked.
