My anti-spam system design went something like this (I integrated
NetMail running on Novell NetWare to SpamAssassin running on SuSe or
RedHat Linux):

default), occurs around the Mail::SpamAssassin::PerMsgStatus::get_hits =

Actually, I'm already doing it for Bayes. When I turned off autolearning
and went solely with manual-training of the Bayes db, I was interested
to see if Bayes, alone, w

Hey Steve,
I was hoping not to do it that way because besides putting the human
mistake-prone factor back in, it skews and warps the heck out of the
spam and ham curves that the SA developers have worked so hard to get
near perfect and trumps their priceless knowledge and experience.
