Spam Sleuth monitors your e-mail box from behind the scenes and analyzes e-mail messages for spam, virus and web bug characteristics. If it determines an e-mail is spam, it yanks it out of the e-mail server and compresses it so that it takes as little space as possible on your computer. When your e-mail program gets your e-mail, the spam has already been removed and you can read the same way you always have, but without sorting through the junk to find the gems.
