Fixing Email

On my way to work today, I saw a billboard that said (in really large letters): Fixing Email. Not just a job, but a passion.
I’ve been running an email server on the internet for five years. I’ve come to the conclusion that the reason spam is such a problem is because email it easy and cheap to send email. So stopping spam (at it’s source) can only be accomplished by making email hard and expensive to send. I believe that is the wrong approach.
I use bayesian classification to filter my email on my machine. I have a 99.93% success rate. The specific product is PopFile and I am here to tell you it works very well.
