        So if I read you correctly, adding 4800 rules essentially triples 
the cpu time needed to process a given message or collection of messages.
        Are there ways to improve the performance of the checks?  I ask 
because these URI rules are tripping on about 50-60% of my current spam - 
much more than the corresponding source domain blacklist rules.

        I hope you'll pardon my ignorance, but I don't know how to read 
the masscheck results.  Were there any other useful nuggets that came out 
of that report?
        Thanks for taking the time to report back, even if I'm too 
inexperienced to understand your response.  :-)
        Cheers,
        - Bill
