Hello Nick!

Even more simpler: I have IPv6 by DHCP, some time ago I configured IPv6 and it was working fine
my uplink and where I crash my netmail can work on IPv6.
All working fine unattended. Suddenly I got a netmail from my uplink telling me that since a few days he sees some error not able to deliver mail by IPv6 but only IPv4 ..
Issue whas that after a firmware upgrade or something else I do not remember IPv6 was not
well activated on the router anymore and I had to apply / restart the router.
Not being made aware could potentially caused my AAAA record being active but never be responsive anymore.
Hence it could be that I could call with IPv6 to my uplink but never got mail back on it only IPv4.
Even now:
I changed my subscription yesterday with my IPS.
they made some network changes. my router does not tell me my IPv6 anymore, but it is still working
In this situation my router should need another reboot probably.
or wait until its DHCP is expired (maybe) ..

... Outsourcing the problem to the next guy.
