Public bug reported:
If the Mailman server implements DNSSEC, it is possible that a DMARC policy record may not be retrieved because of a DNSSEC issue that may not affect a receiver of the message. Thus, to be safe, lookup failures like these should result in DMARC mitigation being applied.
Thanks to Jim Popovitch for the merge request to fix this https://code.launchpad.net/~jimpop/mailman/dmarc-dnssec-validation- fix/+merge/329821.
