dspam

In my early Linux system administration days, when I was first trying to set up a mail server with spam filtering, I ran across a really puzzling bug in Dspam, the software I was trying to get working. While all the other users of the software were getting great results, with Dspam catching 99%+ of all their spam, it was only catching about 70% of my spam after quite a bit of training.

I posted my results, and confusion, to the Dspam mailing list. The original developer of this software (which has thousands of users), Jonathan Zdziarski, responded that that did not sound right.
