[binc] training spam filters?

Has anyone thought about having imapd initiate spam filter training?
This would probably be a lot nicer for end users of the mail system
rather than some of the alternatives -- forwarding misclassified mails
somewhere, running something from cron, going to some web-based thing,
etc.

I'm imagining a fairly generic way to do it would be to have a ".hook"
file in a maildir which contains shell text to be executed when e.g. a
message is filed there.  Then, I'd just have to drop misclassified mails
in a falsepositive/falsenegative folder.

Thoughts?
