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. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
