Just for the record, the Authentication part of DMARC is done with SPF and/or DKIM; the large mailbox providers actually (since 1 Feb) require *either* SPF *or* DKIM passes, or both if you are a bulk sender (thousands of mails per day). DMARC itself remains optional (but recommended) and once taken separately from SPF and DKIM is mainly a reporting mechanism. > I am subscribed to mailop (though don't read it as often as I > should!) but from a mail search there doesn't seem to have been > anything there about this recently. This has been discussed at length on mailop since well back in 2023. Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
