Large mail providers all agree that v6 senders need to follow good mail discipline, but are far from agreeing what that means. It certainly means proper rDNS, but does it mean SPF? DKIM on all the mail? TLS on the connections? At this point, I don't know and neither does anyone else. Fortunately we have at least another decade of full IPv4 mail connectivity to figure it out.
So, what's everyone's feelings about a rather large provider who blocks IPv6 e-mail that has no RDNS, even though the sending domain has SPF records allowing the block, and proper DKIM set up?
*looks directly at Google*Nothing like poorly thought out policy to break a rather successful IPv6 roll-out for multiple customers.
