A little bit more investigation, and the fact that I don't mind my host
being named in public, shows that smtp.hanaden.com points to
hanaden-smtp.dyndns.org. This is exactly the kind of thing that SAUCE
(as mentioned, the anti-spam system in place) is designed to prevent.

Why is it that you aren't using your ISP's smarthost to send and indeed
to receive mail? Or getting a more permanent MX.
