Topic: The guns... they've stopped: Extreme Spam Reduction

Jeff Ballard, University of Wisconsin Computer Aided Engineering
David Parter,University of Wisconsin Computer Sciences Department

"The guns... they've stopped." That is what one of our users
said after we improved our anti-spam configuration.

The UW College of Engineering and Computer Sciences Departments
have drastically reduced the amount of spam. This not only
pleases users, but has significantly reduced the load on mail
servers, mail gateways, and spam assassin servers. We have done
this through a method of demerits and aggressive greylisting,
implemented using the mailfromd package.

We will describe our configuration, lessons learned, and some
"gotchas". We expect everyone else to chime in for questions,
answers, and discussion.

Directions to TDS are on the web

Note: Our regular meeting time will be the second Thursday of each month
(but we had to move it to the first Thursday this time).
