[Spambayes] Cut off doesn appear to be working

[Alan Campbell]

I have set my cut off as follows :-

Ham 0.2
Spam 0.8

I am still getting quite a few messages marked as unsure.  When I
checked the clues for one, it showed the following :-

Surly this should be marked as spam, or have I got the wrong end of the
stick ?
