I assume you mean here that you have 1000 spam a week leaking through? Or
do you mean that you have 1000 spam a week TOTAL and ALL of it gets through?
Setting the required hits below 5, or certainly below 4, is not the answer.
You have something else wrong, I would say severely wrong. You have Bayes
turned on, and it should be taking care of the vast majority of this sort of
thing, if it is properly trained.
If Bayes is improperly trained, it could be causing your problem, by
claiming that some class (or possibly all) of your spam is really ham, and
lowering the score.
That is about the limit of the help we can give from what you posted. If
you posted a typical spam *with complete headers* and *with the scores you
got* we would be able to look at it and probably spot some obvious problems.
As it is, all we can do is guess.
