-
That would indicate that IPv6 isn't supported.

Not supported on PostFix itself, or in the actual server network config?

Just taking a guess, I would say via the networking.

Did you even read anything I posted?

Me too. I have to disable IPv6 on all of my Linux stuff otherwise, I'll get IPv6 DNS answers, yet, my Router does not have an IPv6 address (internally or externally).

So I will try this with both IPv4 AND IPv6 listed and see what happens. Specifying IPv4 only works, but I will try both.
Thanks guys.

The point here is does your server have routable IPv6 available to it?
The postfix instance seems to have IPv6 enable. Your DNS seems to return IPv6 information.:question_mark: Does your router have IPv6 enabled?
:question_mark: Does your ISP support IPv6?

This server is a Vultr box. Not using the Vultr Firewall. I just noticed in the Vultr manage page, that IPv6 is available, but no subnet has been assigned. That will do it!
