Reviewing Anti-Spam Offerings

Joel Snyder writes "Just finished looking into the innards of 40+ anti-spam products at Network World. The biggest, ugliest, and most comprehensive look at this market that's ever been done. Conclusions: lots of great products to choose from at the top (a dozen or more); a few stinkers in the bunch; and it's basically impossible to review Spam Assassin, which is unfortunate."
