[SOLVED] How can I add a AAAA (IpV6) PTR record?


I’m getting the dreaded Gmail ipv6 failure message when sending emails to gmail addresses:
Our system has detected that this message does 550-5.7.1 not meet IPv6 sending guidelines regarding PTR records and 550-5.7.1 authentication. Please review 550-5.7.1 https://support.google.com/mail/?p=ipv6_authentication_error for more 550 5.7.1 information.

I could of course disable ipv6, but I’d rather not do that.
So I’m looking for some help to add the PTR in webmin.

Do I need to first create master zone and then select “Reverse (Addresses to Names)”?

Or can I just go to the existing master zone, and then “Add Address Record”?
In that case, do I need to select “Update reverse?” and I presume I do NOT “replace existing”?

Any help appreciated.



did anyone have time to look at this?


The solution is to add the AAAA record to /var/named/hostname.hosts as follows:

hostname,com IN AAAA longipv6address

then restart BIND.

Don’t forget to ask your ISP/VPS provider to update the reverse DNS so that the PTR points to the hostname,
