mlamb writes "Statistical mail classifiers like PopFile save time on the part of their users, but don't do anything to actively combat spam. I just published an article that suggests a way to use classifier output against a spammer while they're connected to your SMTP server, and I'm launching a project called TarProxy to implement it."

  1. OpenBSD's spamd by almeida · · Score: 5, Informative

    This is the same thing as OpenBSD's spamd, which Theo de Raadt wrote specifically to cause spam relays pain. spamd uses some new features of pf and blacklists from Spews to create a tarpit for incoming messages from known spam relays. It was even discussed on Slashdot in this article. Also, Daniel Hartmeier, pf developer extraordinaire and all around good guy, wrote a little piece about annoying spammers using pf, spamd, and bmf.
