That's odd, I get quite a lot of DCC FPs and a few Pyzor FPs on a relatively small amount of email. They tend to hit on bulk mail, like newsletters, automated mail and very generic mails. I saw a test message with just the word test in the subject hit DCC once.
DCC identifies 'bulk' email. You have to whitelist desired bulk email senders in the DCC whiteclnt (etc) file. The DCC distribution includes sample scripts like edit-whiteclnt. Pyzor and Razor are easier to use because of the whitelisting. Razor and DCC are both highly effective (>80%), and Pyzor is good (>40%). -jeff
