We bought a new server in Hetzner with IPv6 support.
Sending mail to Gmail addresses does not work, with a diagnosis:
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 far as I understand, I need to register a reverse zone for the entire IPv6 subnet. In the robot interface on the IPs tab for IPv6 I write:
***:****:***:4472:: -> domain.com
***:****:***:4472::2 -> domain.com
PTR check returns for IP ***:****:***:4472::domain.com
Doesn't help, same error. What is the correct recording format?

Well, there are several questions here:
1. Do you want to send via IPv6?
2. And between what-thread the servers to send mail on IPv6 and to look as that?
3. Have you tried Google?
4. Show parts of the postfix config regarding IPv6
5. Have you read www.postfix.org/IPV6_README.html ?

And for MX records to prescribe AAAA?
