        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.

                    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!
