Currently it seems that google is blocking email from servers that do not have a IPv6 PTR record. On August 17th .a title=“Waar blijft RDNS? (Dutch)” href=“http://xs4all.ipv6.narkive.com/jOo7yGQe/waar-blijft-rdns".a post./a. was posted in the IPv6 newsgroup of the Dutch provider .a title=“IPv6 at XS4ALL” href=“https://www.xs4all.nl/klant/ipv6/".XS4ALL./a. complaining that their native IPv6 did not have IPv6 PTR records and that this resulted in mail rejection by google.
Why is it so difficult to support IPv6 PTR records for customers?
