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?

Well here a few questions:

1. You want to send it via IPv6?
2. And between which the thread of their servers to send mail over IPv6 and to look like that?
3. Google tried?
4. Show pieces postfix'and config about IPv6
5. www.postfix.org/IPV6_README.html read?

1. No, not fundamentally, but don't know how to send it via IPv4
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
With chesnara to become interesting, what with ipv4 works well, glad something helped :) - kevin.Smith commented on October 3rd 19 at 03:46
Thank you so much for the help with Postfix!
But in light of the transition to IPv6 you still need to keep digging :) - sunny commented on October 3rd 19 at 03:49
With IPv6 I will dig, as he is gradually on his turn and ssh is already running on it between the different machines where you may need to deal with SMTP, I agree. - kevin.Smith commented on October 3rd 19 at 03:52

And for the MX records to register the AAAA?
MX records point to Google Apps for your domain. Error occurs when sending mail by means of servers (postfix). On a similarly configured server without IPv6, all works without problems. - sunny commented on October 3rd 19 at 03:45
