Sure.  For example,

    yield 'From: has a malformed address'

The "words" we generate can be any strings whatsover.  But you knew that.

Ditto.

Ditto.  If you want to tackle this, that would be great, and I expect these
are pieces of evidence we could enable regardless of corpus source.  Very
brief msgs are darned hard to score, and I expect there's a world of info in
the headers I'm not getting at now.
