The first irritating spam in quite some time; and I think it might be enough
to make me start using greylisting at smtp-level (if that works with these, I
haven't checked the headers close enough to see what's going on).

If it's spam, then it's spam... My view is that if you've got a "learning"
filter then just hand it all spam and ham, and let it sort it out; if it can't,
then it's either broken by design or outdated.
