Email is not configured properly

[dynimighti]

the previous post have no answer. PTR6 DNS record (PTR) did not match. what is the solution?

There are now many post about mail and IPv6 included PTR.
The forum search is a powerful tool

You need to set the PTR Record for your IPv6 in your hoster.

@BrutalBirdie to be fair though I have the PTR records set up for a long time now but for some reason I keep getting these errors lately too

[jdaviescoates]

@andreasdueren I've intermittently got them a few times too.

So the issue is that the PTR does not match the ipv6 or that it is intermittedly resolving to the wrong value or is there any other issue? If so more info would help to get down to it.

I also get this error message from time to time on my Cloudron on Hetzner VPS. Usually during night and when I check in the morning the issue does not exist anymore. Maybe it is an issue with DNS Lookup?

@nebulon This is the error show:

What kind of intermittent maintenance could affect this?
