I was an early adopter of Vipul's Razor - the service on which the
Cloudmark product is based. I funnelled some fifty thousand or so spam
messages through razor-report before I finally gave up in despair some
months ago - they simply couldn't keep their reporting servers up. I'm
glad someone finds the for-pay Windows product useful, but IME people
who actually feed the hash databases are abandoning Razor, so the future
of the product is questionable. I found it only gave us about 40% hit
rate on spam, letting 60% through, whereas blocking on other factors
blocks 90-95% or more. Filtering on content is always iffy.

Yuck. C/R, for anyone who runs a mailing list, is a bane. I unsub
anyone using C/R whose systems are too stupid to know when they're
receiving mail sent via a legit mailing list. I sincerely hope it
doesn't come into wider use, or that if it does, it gets a hell of a
lot better than the systems I've seen...
