Last night, I ran SC2 against a corpus of 119,000 messages consisting of
about 97-99% ham. This was a corpus of mostly ham mail which had made it
past my filter over the past few months. (BTW, my percentages keep getting
better, so most of that small percentage of spam in this corpus was from a
few months ago).

SC2 caught about 150 messages from this corpus. ALL of these caught messages
were spam. It did NOT "block" a single ham.

Hi Chris,
I've not heard back from any SA corpus testers yet.  Has anyone

Does anyone else have any results for SC2 to share?  It seems to
hit about 10-15% more spam for different folks, but is it any
better or worse on hitting ham (false positives)?
