it is nothing wrong with having ipv6 support, it will be even mandatory in the future, you just should assign a dedicated ipv6 to your mailserver and add the correct PTR to it aswell and implement it in the SPF, then everything should be fine


Since the server is hosted by flipperhost, it was easier to disable on the server (google was my friend).

Emails are now going through.

Thanks for the help, I never would have figured that out.

the server is sending trough IPv6, and this specific ipv6 doesn't seem to have a ptr indeed

My hosting provider moved my system to a new center and thus changed my IP.  I had them update the PTR record , but haven't updated anything else - all recipients get email except Gmail which bounces.

mail-tester.com give my email a 10/10, so IT doesn't think anything is wrong.

I get this attachment as a 'Delivery report':

MxToolbox.com states that I don't have a DMARC policy  enabled; but I have dmarc, spf and DKIM records set.

Question: Does the DKIM record (which is binary) contain the IP of the server?  If so, what's the best way to regenerate new dkim records and kill the old?

Is there something else I should change in my DNS settings (settings are at namecheap.com) to update from the 'old ip' to new - everything visible has the right IP?

Is there a change I should make to some file in the server to indicate a new IP?  Could this even be the problem?


Thanks for looking.


Andrew
