FWIW, I did offer to set up spam filtering for this.  Need to know how 
they process their mail, and we can set up an annotation pipeline 
(complete with Bayesian, heuristic, and other filters).  At the end of 
the process, we have a pretty good score and cutoff for spam vs 
not-spam.  We use that for our filtering.  Since we get a couple 
thousand emails running through the filters a day, we get maybe 3-4 
false positives, and a few false negatives that we correct by hand 
(training the Bayesian network).
