Of Spam & Men

Spammers spam and I make a living stoping spam (well, that's not the only thing i do) and i do it well. At work we use a combination of Spamassassin and CRM114. That's a combination of two different antispam mechanisms:

• static rules, matching keywords in headers or/and body
• a learning filter capable of classifying mails using bayesian statistical methods (spamassassin) or the Markovian discrimination method (CRM114)

This system isn't perfect but give pretty good results: 99.6% of the spam that were sent to my addresses were detected. But that was before they started using poisonning methods and captcha images...
