Ok, this is pretty bad replying to myself twice in one day. But, I
managed to find a dynamic ip connection that's listed in one of the
dnsbls and then tested sending mail from it. As long as you authenticate
successfully, it lets you through, otherwise it rejects mail because of
the dnsbl listing (and relaying too, obviously).
