Conference on Email and Anti-Spam
The Conference on Email and Anti-Spam is an annual scientific conference sponsored by Microsoft on subjects relating to email use and abuse. The CEAS hosts a concurrent open competition for spam filters known as the CEAS Live Spam Filter Challenge.
The first conference was held on July 30–31, 2004. Until 2008, the conference site has always been in California, either Mountain View or Stanford University. The web site is also apparently hosted at Stanford University.
The sixth conference of CEAS is held in Mountain View, California. And the seventh conference will be held in Redmond, Washington.
