The score that worries me here is KNOWN_ADVERT_DOMAIN. We don't send spam.

The WEIRD_PORT probably got flagged because of a few messages that had URLs
to my NPDS tracker server, which is on port 3680. Using URLs with
non-standard port numbers is a known spammer trick.

TONER because lots of spam are ads for toner refils :)

The last three rules that matched didn't actually add to the score, so it
seems that the mail admin has turned these rules off.

Probably the best thing would be to find out how to reach the mail admin guys
at UTORMail and ask them to whitelist newtontalk.net.
