I had a problem with my personal server for a little while; all my SPF, DKIM, etc was all set up for IPv4. I have a couple IPv6 interfaces on my machine, and my mailserver was delivering to GMail over IPv6!!



Yeah, most of the time reverse DNS on the IPv6 address is not configured, leading to rejection.
