If you use e-mail regularly, the spam clogging your in-box has no doubt reached the point where you cant continue without doing something about it. Fortunately, spam-blocking utilities and services for both individuals and corporations have improved by leaps and bounds over the past year, drastically cutting the amount of spam you receive while reducing the chances that legitimate mail will be blocked.
