Public bug reported: If DNS lookup of TXT records for a domain finds more than one v=DMARC1; record, it checks them all for policy = reject or quarantine. RFC 7849, Sec 6.6.3 item 5 says 5. If the remaining set contains multiple records or no records, policy discovery terminates and DMARC processing is not applied to this message. Thus, if we find multiple records we should assume no DMARC policy for this domain. ** Affects: mailman Importance: Low Status: Triaged -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/1931029 Title: DMARC policy lookup violates RFC 7849.
