I'm no expert, but I'll explain to the extent I understand it. SPF validates the envelope. This is the oldest of the three protocols. DKKM validates the integrity of the headers, at a minimum, the integrity of From. You may have noticed that every single message has an invalid From. Therefore, there's nothing for DKIM to validate. This is a setting in mailman that can be changed. DMARC was demanded by the major email providers when they were accused of being the main sources of spam, which they certainly were. DMARC, DKIM, and SPF are not spam countermeasures. Then, after demanding that everyone follow the standard, they implemented DMARC in a nonstandard way on their own mailing list servers. Note that a mailing list server MUST NOT change specific headers, particularly From, but they do this so that ENVELOPE FROM matches From, which was never required of the DMARC standard and is nonstandard behavior with respect to all other email standards. Basically, in case a mailing list itself were the spam source, the big email providers simply didn't want domains they own to be used on From, even though it's literally the author's mailbox. mailman and other mailing server applications followed suit, even though everybody knew that the major email providers failed to implement DMARC, the standard that they demanded be written, in a standard manner. _______________________________________________ gnucash-user mailing list [email protected] To update your subscription preferences or to unsubscribe: https://lists.gnucash.org/mailman/listinfo/gnucash-user ----- Please remember to CC this list on all your replies.
