Spam also known as bulk email or junk email, is a huge problem for anyone who gets e-mail. According to Business Week magazine, in a single day in May 2003, AOL Time Warner, the US's no. 1 Internet service provider, blocked two billion spam messages – 88 per subscriber – from hitting its customers' e-mail accounts. Microsoft (MSFT), which operates the No. 2 Internet service provider MSN, as well as Hotmail, says it blocks an average of 2.4 billion spams per day. And that's all five years ago. You know those numbers are much higher today, five years later. __
