That software costs $1000 minimum.  However, there is an evaluation 
version available.  I don't see why spammers would use the eval version 
of a full-fledged mail server instead of one of the great many free 
or cheap programs designed solely to do mass mailing, but I accept that 
it's within the realm of possibility.

I would be interested in seeing the ratio of spams detected versus 
false-positives based on this test.  Is that what determines the 
"default score" for a test, by the way?  Or is it something else?
