I'm deep into monitoring false positives, passed spam, and valid near
misses. I'll post some info tonight or tomorrow. One thing that is very clear thus far is that FIVETEN detects a lot of spam that other blacklists don't, however they also have a very high false positive rate which is why I score them so low. Three of the FIVETEN tests marked 15 of 40 pieces of spam that got in under the top score, however it also marked 12 of 17 valid near misses (passed legit stuff) from newsletters and other sorts of automated mailings like opt-in lists and receipts. It also marked valid yahoo.com accounts which tend to fail several minor technical tests. Then for my false positives (rejected valid E-mail), it marked 3 of 8 messages. One note about what I am counting as valid here. There are varying levels of commercial E-mail and I am trying to pass anything opted-into directly or resulting from being a customer of that mailer. Most of this stuff is of no value, but I don't want to block it if I can help. SPAMCOP for instance is blocking a fundraising letter from George Bush's campaign that includes the customer's full name, and the NYTimes.com daily update fails FIVETEN-SPAMSUPPORT as well as SPAMHEADERS. Some companies use outside sources for their mailings and they suffer from not choosing wisely the company they deal with. So with the above results, I definitely would include FIVETEN in any setup, but score them very low in respect to others, hoping that they fail some technical tests to put them over the edge. The numbers in the summary are from my settings where I fail on a score of 10, and I don't score technical tests very high (though I'm probably going to increase BADHEADERS).
