Although I dislike the term, ham to me is legit e-mail.

No, I mean what does Ham mean?  Does Ham mean legit e-mail?  Or is that 
like
mail from BulkSenders which some people might consider Spam and some might
consider legit?

My weighting system is this:
<100 No action (27.7% of all mail in Jan 2005)
100 Subject tag  (.5% of all mail) (1/3 of this weight range tend to be
spam)
200 Hold  (.5% of all mail)  (I average 1 a month of Ham in hold)
300 Delete  (71.3% of all mail)
As I have to draw a line somewhere, I drew the line at 200. Everything
held
or deleted is considered spam.
Everything under 200 is considered ham, I think this is fairly
conservative.
