Gmail: this message does not meet IPv6 sending guidelines regarding PTR records


I am trying to email myself (on Gmail) a Nagios alerts and it's rejecting all mail:

Code:
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.
The bounceback:

But my domain (biyg.org) does have AAAA record:

Code:
2605:8900:1000:1001:5:0:27:2
And my hostname is:
Code:
biyg.org
Which matches what Google saw.

What am I missing?

The easiest solution is to switch postfix to ipv4 only. Add the following line in the postfix main.cf file and restart postfix:

inet_protocols=ipv4

If you like to use ipv6, then you will have to check 2 things:

1) is there a IPv6 recrd (AAAA) for the hostname "casrv02.myserver.com" in the zone "myserver.com" that points to the IPv6 address of your server?

2) Does your IPv6 address has a reverse dns record that points back to the hostname "casrv02.myserver.com". The reverse recod for the IP has most likely to be set in the ovh controlpanel of the server / vm and not in ispconfig.

Above text from this link: https://www.howtoforge.com/community...roblems.64675/


If IPV6 is not a requirement, stick with IPv4 first.
