In your /etc/hotst file - disable the IPv6 lines.

or add an ipv6 PTR
-
or add an ipv6 PTR
Can you advise how?
I've tried but couldn't manage unfortunately.

it would depend on your dns host but it needs to be done there who are you hosting with ?
-
Hetzner.
-
Ok they have a dns panel but you may have to mail their support to add the ptr record for you

Hi im facing this exact issue.
Im hosting on Linode, no idea on how to add an ipv6 PTR
If i disable the IPv6 lines, it will work?
What is best, and how can i do this.
-
Try to ask Linode support about them IPv6
Also, you can disable IPv6 in Postfix configuration. Add/change in /etc/postfix/main.cf
inet_protocols = ipv4

I have disabled all ipv6 with my linode dns settings. IPV6 is still a very big problem for everyone.

IPv6 is not a problem, the problem is not configuring things properly.
We bet on IPv6 in all our clients' accounts, it has some problems, but the solution is not to forget about it, it is to try to solve the problems.

Thanks for your answer, i have reached Linode Support and they point out this guide.
https://www.linode.com/docs/networking/dns/configure-your-linode-for-reverse-dns/
My question is im using same IP for multiple domains, so i guess i need to create an entrace for each domain??.
I will try to set ipv6 correctly before disabling.
Thanks very very much,

This solution works fine.
