If you could provide an example message that was incorrectly classified,
along with the "clues" for the message (on the review page there is a
"Clues" link that will get you this), that would help us a lot.  You might
even be able to see why the message scored what it did yourself, but if you
can't, we should be able to explain.

Note that it's fairly common for the majority of unsure messages to be spam.
Sometimes altering the threshold can fix this problem (if they're all
scoring > 75%, for example).  You should only get ~2-5% of your messages
classified as unsure, though.
