Tim, first I want to thank you for letting me post to your blog. It sounds like you have a good product in SimpleFilter and I wish you good luck in marketing it. I've added a blog of my own as an experiment - usebestmail.blogspot.com and you are welcome to post there. In spite of your negative review I hope others less committed than you will actually give UseBestMail a try and report their experiences. It is very difficult to introduce the world to an unfamiliar concept because people are seldom willing to be the first to try a new thing. But the battle isn't won until the spammers cry uncle, and that will probably take some innovation.
