Describe your issue
I have configured the RDNS IPv6 entry for domain correctly (the address is reachable and is displayed as RDNS). The first diagnosis shows that everything is configured correctly. The second run later shows an error in the RDNS IPv6 configuration (I have posted the logs below). Same error as here: Rdns for ipv6 and automatic diagnosis
I’m not that experienced to find the cause. Restarting doesn´t help, flushing DNS-cache doesn´t work. But if I change inet_interfaces = all in /etc/postfix/main.cf to the specific IPv4 and IPv6 addresses , the error in the diagnostics is gone. Except for the error that the file was changed manually.
My questions: Is this really a solution or can this possibly break something? Is there another solution?
