Doug,

Continue to train with all the unsures.  That's pretty much necessary
to keep bogofilter up-to-date.

Be careful with "-u" and false positives (FP) and false negatives (FN).
When using "-u" false results tend to magnify unless you watch for such
message and retrain properly with them.  For a FP (ham scored as spam),
it is necessary to run bogofilter with the -S and -n flags.  For a FN
(spam scored as ham) run bogofilter with the -N and -s flags.  These
flags are described in bogofilter's man page.

HTH,

David
