No, what he said was that ESPs *could* give a hint. All RFCs and IETF recommendations are just that - recommendations. Nobody is under any undue influence to change the way they do things or to implement a new feature. The only side effect is that eventually you will be outmoded by those who do implement the new features and capabilities described in newer recommendations. An RFC 822 email server is perfectly able to send and receive mail today. It will work whether or not SSL, TLS, SPF, DKIM, DMARC or whatever the new post-facto implementations may offer. It will not have all the same features, and some operators may *choose* to deny mail from the server for neglecting to implement any one or all of the above, but the recommendation stands on it's own to be implemented or ignored by whoever opts in to using it. That someone is pushing for more effective MUA hints for list management isn't a bad thing, it's just got to get a lot of traction before it's useful. -S _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
