Spam Tools that Work

The next meeting of the Front Range UNIX Users Group (FRUUG) will be held at 4:00 P.M. on Wednesday, September 25. Since we have to vacate the room at 5:30 on that day, we will start promptly at 4:00 P.M. At this month's meeting, Barb Dijker will be updating us on tools to fight spam that really work.

The volume of spam that both users and ISPs must deal with is increasing at an astronomical rate. There are many tools to help curtail the flow of spam ranging from DNS-based blacklists to mail client-based filtering schemes. This talk will provide an overview of the latest tools and techniques for managing spam, focusing on one tool that really works: SpamAssassin.

SpamAssassin can be installed and used by one person or integrated into sendmail to block spam for an entire site. It uses a rule base to assign a probability that a message is spam. It is over 99% effective at identifying spam. The talk will go into detail about how to install, use, and customize SpamAssassin.

About the Speaker

Barb Dijker has been fighting and analyzing spam for many years as a consultant, and is involved with two local ISPs, Netrack, Inc., and Colorado Internet Coop. She has given talks on spam around the globe and has served as an expert witness in a legal case involving spam.

Meeting Location

This meeting will be in room 123 of the CU Academic Computing Center building at Arapahoe and Marine Streets in Boulder. Marine St intersects Arapahoe at 38th St; the Computing Center is on the southwest corner.

Our Last Meeting

At our last meeting in June, Wally Wedel, Master Java Architect at Sun Microsystems (and long-time FRUUG Executive Committee Member) discussed how well he's been able to use MacOS X in everyday use in his consulting work. Besides drawing Macophiles out of the woodwork wherever he parks his Titanium PowerBook, Wally finds that the UNIX base of MacOS X provides the support he needs for his everyday Java software development as well as for running his "productivity" applications.

Wally's slides are available in the FRUUG meeting archive at
