Well there certainly has been some discussion on the MAAWG senders' list about naming conventions and clarity or rDNS resolution HELO, and so on and it is something *we* recommend to our certified and safelisted clients (beyond FQ rDSN which is a requirement), but blocking on something that is far far far from an industry standard?
