we feed email originating from reliable hosts on campus to the  
Bayesian engine as ham.  We encourage people to forward missed spam to  
a special email address where we check it before feeding it to spam  
assassin (so we don't have the AOL problem where (I'm told) the mark  
as spam button is right next to the delete button.

I too have my doubts as to exactly how effective this is particularly  
given that most of the stuff getting through now is explicitly  
designed to confuse a Bayesian filter  (over 90% random garbage) .    
I'm on the point of saying, if we can't automate this then we skip the  
Bayesian filter altogether.  Hence my original question.
