Bogofilter's configuration includes 2 special parameters used in
identifying ham and spam.  The parameters and their default values are:

  ham_cutoff=0.45
  spam_cutoff=0.99

Any message whose score is 0.45 or less is marked as ham.  Any message
whose score is 0.99 or above is marked as spam.  All other messages are
marked as unsure.

The default values were chosen to minimize errors in classification.
Until bogofilter is trained with a fair amount of _your_ ham and spam,
a lot of messages will be classified as unusre.

When you have a message classified as unsure, the best thing to do is
decide whether it is ham or spam and train bogofilter accordingly.  The
man pages and FAQ have a lot more information of this subject.

Hope this helps,

David
