Would this group agree that requiring 5 hits in order to classify an email as spam is too conservative a number?
Nope. I've been running a number of systems - personal and professional - at 5 with no major runs of missed-spam or mistagged-ham (aside from the period where I was still running 2.64 when 3.1 had been out for a while...)
Careful and dedicated mistake-based feeding of Bayes, keeping an eye on FNs and occasionally creating or tweaking a rule to bump a not-quite-tagged spam over the threshold all help to keep ham in the inbox and spam in the spam folder(s).
I suspect ISPs have their filter settings at 3 or less.
Heck no, not here anyway. If I did that a fair chunk of legit customer mail would get tagged. Tagging Legitimate Customer Mail Is Very Bad.
In fact, I've *raised* the threshold on a couple of role accounts to 8 to make sure *legit* mail gets through.
We run a number of addon rulesets but I'm not sure they're really adding that much to the scores on most of the borderline mail.
