A day ago my provider changed my ipv6 and now I don't know how I can update it in my directadmin panel.
Because every time I send an email it tells me that I don't have the PTR configured for ipv6, when I actually have another one.

SMTP error from remote mail server after end of data:
550-5.7.25 [2602:fd92:110:12::b] The IP address sending this message does not
550-5.7.25 have a PTR record setup, or the corresponding forward DNS entry does
550-5.7.25 not point to the sending IP. As a policy, Gmail does not accept

And this is the new ipv6 address they gave me.

Also add the new ipv6 in IP manager

I need help, I don't know if I'm doing it right.:)
 
When I do a reverse IP search on 2602:fd92:110:12::b I also get no records back. (If that is your server IPv6 address)
So you should check if your host also updated the PTR record because it seems like they did not.

EDIT:
Sorry but the IPv6 is from Gmail.

And for the IPv6 that you showed from the IP manager I get the hostname "undefined.hostname.localhost" back. So the PTR is definitely not configured correctly.
 
You should check your dns records for the server hostname and add/change the aaaa record with the new IPv6 address.
 
Add the following AAAA records for ipv6

Now that I did dig -x to ipv6 it doesn't recognize my host which is what happened.

Am I right or am I wrong about something, thank you very much for all the help.
 
Contact your provider (my guess is your server is not in a DC) and ask them if they can make a PTR record for your IPv6 address.
