ETNyx For me ipv6 caused emails not sending properly to some providers like gmail (emails bounced) so I disabled it then email sending worked
[unknown] I tried actually sending an email with telnet over ipv6 and it seems like I got an email in my inbox without any authorization. In the logs it says: connect from unknown[172.22.1.1]
so somehow it allowed the ipv6 connection to Postfix even though I disabled it.

also sorry for the weird formatting in the message above, seems like the forum bugged out there.
