PTR records for IPv6 at hetzner?
Bought a new server in hetzner with IPv6 support.
Does not work sending mail to Gmail addresses, with a diagnosis of
Our system has detected that this 550-5.7.1 message does not meet IPv6 sending guidelines regarding PTR records 550-5.7.1 and authentication.
As I understand it — I need to register a reverse zone for the entire IPv6 subnet. In the interface of the robot tab IPs for IPv6 prescribe:
***:****:***:4472:: -> domain.com
***:****:***:4472::2 -> domain.com
Check PTR for the IP returns***:****:***:4472:: domain.com
Does not help, the error is the same. What's the correct recording format?

And for the MX records to register the AAAA?

2. Their mail servers are not all on Google.
3. Googled your third link. Where did the idea that the form of reverse zones will solve the problem.
4/5.Look in the config of Postfix, I should have guessed. The problem with sending mail solved replacement on ip4 only.
But the question of the proper prescription in the robot hetzner PTR for IPv6 remains open... - sunny commented on October 3rd 19 at 03:43
But in light of the transition to IPv6 you still need to keep digging :) - sunny commented on October 3rd 19 at 03:49
