Not DKIM, DMARC to be more precise. I'm certain that close all of the domains people are sending from if they have a DMARC record, it's p=none which shouldn't trigger the 822.From rewrite, but that's what seems to be happening.
lists.nanog.org is configured to rewrite the from regardless of DMARC setting. Even if you have p=none, it still shows as a broken signature on the email and will be rejected by google/MS/etc. They are large enough to violate the standards and we all have to submit, unless you pay for delivery to their customers. If you have a normal email address that's not through the big three, you will probably not have delivery issues on lists. They won, we lost; get over it. :-( -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net
