Would this group agree that requiring 5 hits in order to classify an email
as spam is too conservative a number?
I wouldn't.
We reject everything with a score of 18 or higher, quarantine
everything with 9 or higher (I read the quarantine reports every
work day), and let everything else get through with spam score
(numeric and as "**") in headers.
Individual users are free to filter based on the headers if they
like, but most don't.
Of course, the optimal thresholds depends on how your system is
setup, what happens when the score gets over a threshold, what
rules you use, how well your bayes system works, how important it
is to avoid FPs etc, etc.
