That's my suspicion too, although I figure I'm conducting a real-world
experiment to see if that's true.  So far fns and unsures are not
unmanageable, after a brief period of instability.

A generalization might be to score each attachment (or possibly just
each message/rfc822 type attachment) separately.  Then choose an
algorithm for combining the scores, e.g. outer-only, inner-only,
combined, etc.
