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.
