Spam Filtering
«

If anyone wished to talk about the ins and outs of spam filtering let me know. Â
Ours is based on a e-mail score. Â Bad phrases from known spamers will give the e-mail a + score. Â Good things strings (fur, furry, furtopia, dragoncity) will give subtract from it's score. Â Any e-mail with a score over 50 gets the boot.
'>
Bellow are a few logs from the spam filter showing how things were scored. Â On average Furtopia gets hit with 1 spam message every 5-10 seconds. Â In Ohio it's illegal to spam e-mail addresses at some domains (including ours). Â But there are so many people who don't care how much they hurt someone's bandwidth as long as they can take somebody's money it's all worth it to them. Â So the next step is to guard dog the e-mail gates.
The reject logs are HUGE in multi-megs already. Â But I can't help but grin every time I look at the logs knowing I've so far kept the plague outside.
'>
Take a look bellow. Â Most addresses are faked. Â But our program searches the whole e-mail. Â Take a look you'll notice negative scores are kept:

Cool, did you write the program yourself, or what?

I'm assuming he's using Spam Assassin or something.

Oh, faint memory trickles, that is all; like a stream that rustles forgotten leaves and lost paths.

Actualy I'm using a program called Weasel and Weasel Filter. The filters I have made over the last year. Every time a spam gets through I add strings from it to catch. So the net gets tighter and tighter.
