Falling behind

Posted by bronson Fri, 02 Dec 2005 15:49:00 GMT

I’m now averaging about 350 spams per day. SpamAssassin catches maybe 15% (spammers are getting pretty sharp) leaving somewhere over 300. It’s pretty easy to go through by hand each day but when I miss a few days it gets really painful. And when I miss two weeks (the Drive + Thanksgiving) and now have 9570 “special offers” to delete, I crumple. I can’t bring myself to go through this mess. Something must be done.

The problem is, changing a mail configuration always leads to a few months of instability. Always. Ah well, like the heater core, better now than later. Thank goodness for unemployment!

    Hi,

    I had the same problem with SPAM. I would be very interested in seeing how my spamassassin config would cope with your spam volume.

    I ended up configuring a new domain (www.spamfreemail.de) with my own combination of SA / Postfix / RBLs / Bayes / Razor+Pyzor and some custom scripts, and allowing others to subscribe to it too. If you want to try it out, please tell me, I’ll set you up with an account.

    Note that while SpamFreeMail has over time become attached to a commercial web hosting service, it’s still free, no strings attached, no sponsored newsletters etc., and you can feel free to ignore me if you want to. But I’m still curious whether I can improve your filters. ;)

    I’ve tried SA and some custom rulesets but none worked very well. To get better than 90% accuracy, I had to crank the screws up so tight that I was getting false positives. I don’t think heuristics will ever work (not unless people learn to write their own rulesets).

    I’ll try dspam next. I’ve also heard that greylisting and sender verification are very effective techniques. And, I’m probably going to dump Postfix in favor of Hula.

    We’ll see…

    Das leidige SPAM-Problem
    Ah, es gibt also doch noch andere Leute, die ähnlich viel SPAM bekommen wie ich. Ich merke es allerdings nur noch an den SpamFreeMail-Statistiken. ;)
