Spam—the unwanted e-mail that that clogs our inboxes with advertising and tries our patience— actually dates back to the earliest days of the Internet, before there was a World Wide Web, when the entire network consisted of only a few hundred computers distributed among universities, research firms, and parts of the Department of Defense. On May 3, 1978, Gary Thuerk, a salesman for mainframe maker Digital Equipment Corporation, invited all 594 people on the Internet to a product demonstration. It caused an uproar at the time, and it’s only gone downhill since then. Today, with millions of people on the Internet sending billions of e-mail messages a day, it’s hard to believe how bad the spam problem has become. MessageLabs, a large spam filtering service used by Internet service providers (ISPs), has estimated that spam made up more than two-thirds of the entire e-mail volume worldwide in mid-2004, and that it will probably hit the 75 percent mark by the beginning of 2005. MSN Hotmail, for instance, receives more than two billion spam messages each and every day, targeted at the users of its free e-mail service. Defend Your Inbox, Lest You Drown in Spam Spam’s inauspicious beginnings have led to one of the biggest “arms races” in the history of computing. As spam-fighters learn new techniques and devise new tactics to combat the menace, spammers (the folks responsible for sending the junk) develop new tools to defeat the antispam crowd using ever-increasing technological sophistication. For every advance the spam filter companies make, spammers always seem to figure out a new way to work around them.Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. CHAPTER 9: Fight the Junk E-Mail Plague 233 Where they once needed long lists of working e-mail addresses, spammers no longer need to even know the e-mail addresses of their victims before they strike. With increasing frequency, spammers are turning to highly advanced, automated tools that take advantage of the legitimate functioning of e-mail servers in order to deduce real e-mail addresses. If you don’t get spam at an e-mail address that isn’t protected with some form of spam filter, it’s only a matter of time before you do—it’s as simple as that. That’s why it’s so important to learn how to take advantage of spam filters. Spam filtering tools have become, without a doubt, an indispensable tool for virtually every computer user. Later in this chapter, we’ll introduce you to two of the best filters, and we’ll show you how to use them to your greatest benefit. Fight Spam on Your Terms, on Your Turf Nobody except a spammer loves spam. If you’re frustrated with spam, you’re not alone. Fortunately, some very bright minds are working on solving the spam problem—after all, they’re getting spammed, too. The first step to cut your spam is to understand how spammers get your e-mail ...
