Recently Added ipv6 to my box but cannot for the life of me get MIAB to send via ipv6. I tried forcing postfix to ipv6 only but then Roundcube can’t connect? The address is routable and has an AAAA record so I’m a little lost on where else to look. The issue is that my IP block in the datacentre I am in is blocked (the whole /16) so I want to send via ipv6 instead.
At least, I want to do that for now until I can get an SMTP relay setup. Any ideas or areas to point me?
Thanks! I assume I am just missing something simple from a setup perspective but I have been hitting my head against the wall for 2 weeks now. And I’d rather not have to move the VM. So I guess you have another customer haha. It better be as easy as you say…
