It adds subject tags, too. There are good reasons that lists modify the messages. >But SPF passes in general for mails from that list because the sender is >@mailop.org (not many lists do it like this though). >Because of the above SPF is even "aligned" and therefore DMARC passes >that message. Sorry, that's just wrong. For DMARC, SPF alignment means the MAIL FROM domain matches the From domain. >What I'm missing nevertheless as another mitigation on that list is an >ARC-Message-Signature and an ARC-Seal from the listserver. Mailman 2 doesn't do ARC. For that they need Mailman 3 or Sympa.
