$ dig txt _dmarc.aol.com ... ;; ANSWER SECTION: _dmarc.aol.com. 3600 IN TXT "v=DMARC1; p=reject; pct=100; rua=mailto:d...@rua.agari.com; ruf=mailto:d...@ruf.agari.com;"; So, they are still publishing p=reject, and in any case if their policy changed so dmarc_moderation_action wasn't being applied, the mail wouldn't bounce for DMARC either. First, ensure that the list's Privacy options... -> Sender filters -> dmarc_moderation_action is Mung From. Assuming it is, if you have access to Mailman's logs, check the 'error' log for messages like 'DNS lookup for dmarc_moderation_action for list <listname> not available' which means that import dns.resolver from dns.exception import DNSException (from the dnspython package) failed. Also look for messages containing DNSException or DMARC. Check the 'vette' log for messages like '<listname>: DMARC lookup for u...@aol.com (_dmarc.yahoo.com) found p=reject in _dmarc.yahoo.com. = v=DMARC1; p=reject; pct=100; rua=mailto:dmarc_y_...@yahoo.com;' which would indicate that the lookups are being done. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
