Most people use OpenDMARC and there are patches to mark certain hosts as mailing lists senders, so it is possible.
Wonder how many would do this though?
Yeah, unfortunately not enough...
And everyone using p=reject should think about it as well - as I said, DMARC does not play well with mailing lists, so setting p=reject on a domain used to participate on mailing lists is not wise, to say the least. You should not follow Yahoo and AOL - you know, why they did it, don't you?
Unfortunately this is usually required by many common providers such as microsoft and google, otherwise they refuse your mail.
That is definitely not true. They might require you to have DKIM and/or SPF and maybe even a DMARC policy, but they definitely don't require p=reject! Most of my domains have p=none and our mails are accepted by all major providers...
Hope you understand .
Understood. Had to write that mail anyway ;-)
