For years people have been fighting spam the wrong way. Most spam filters try to specify what kind of messages to reject. It’s like defining a wheel by specifying what it is not. - Define rule: Don’t allow square shapes. - Somebody will send you a ‘wheel’ with a triangle shape. - Define rule: Don’t allow triangle shapes. - Somebody will send you a ‘wheel’ with an oval shape. - Define rule:.. As you can see, it’s an endless job. Every time you define a rule, somebody finds a way to avoid it. With spam it’s the same: whatever type of rule you define, the spam generators will find a way to generate spam on which al those rules don’t apply.   But specifying a wheel is pretty easy: A solid disk or a rigid circular ring connected by spokes to a hub, designed to turn around an axle passed through the center. Specifying Email is just as easy: Private messages from real people I want to receive. This is where SpamBright steps in. It’s not a spam-filter that tries to identify spam (which doesn’t seem possible), but a program that identifies email (which isn’t that hard). SpamBright will keep your mailbox clean.
