![]() How serious is spam? The Postini Resource Center says 10 out of 12 e-mails are spam and The Wall Street Journal estimates it costs business $8.9 billion a year for the software and labor to separate it from regular mail. But the Direct Marketing Association says there’s a positive side to unsolicited e-mail. In a recent 12-month period, 45.8 million Americans (9% of all mail users) made a purchase in response to an e-mail ad, yielding $7.1 billion in sales.
Efforts to outlaw spam have failed mostly because it’s hard to define. Microsoft says spam is “unsolicited commercial e-mail sent to advertise a product or a service,” but merchants contend that most advertising—through the mail, magazines, radio or television—is unsolicited. Federal Trade Commissioner Orson Swindle has adapted the oft-used definition of pornography: “It’s anything I don’t like.” The technical name for spam is unwanted commercial e-mail. Using the name spam for junk e-mail comes from a Monty Python skit in which a song containing the word was repeated many times.
REDUCE THE CLUTTER
Step 1: Never reply to spam. This includes clicking any link from sources you don’t recognize inviting you to unsubscribe. Step 2: Use “plus-addressing.” You can obtain several addresses, each with a slight change, from any of several free e-mail services, including www.hotmail.com , www.juno.com and www.yahoo.com . So in addition to rjones@sbc.net, you can use rjones1@sbc.net or rjones2@sbc.net. When registering online for content or services, use one of the plus-addresses—and keep your regular address private. Step 3: Use the spam filters provided by your e-mail software—Outlook, Eudora and Thunderbird, as well as antivirus software and firewalls. Or check whether your e-mail Internet service provider (ISP) is using spam-filtering techniques. If not, consider switching. Step 4: Consider not using the preview pane in your e-mail package. When you open a message in which that feature, showing the first few lines of each e-mail, is activated, it reports back to the spammer that your account is active and valid. Step 5: Do not include links to your e-mail address on your Web site. Step 6: Use antivirus protection and firewalls to protect your computer from being used by spammers. Step 7: When registering for information or content on the Web, uncheck boxes that invite mailings. Step 8: Don’t forward chain letters, petitions or virus warnings from sources you don’t trust. They’re used by spammers to collect addresses.
MANAGEMENT STRATEGIES
One of the headaches caused by spam-fighting programs is false negatives that fail to block spam and false positives, where the software labels a legitimate e-mail as advertising. Manage false positives by using software that blocks suspect messages in a quarantined area while letting users set up lists of trusted sources. Remember to test your antispam strategy and software prior to full implementation. You can create shadow e-mail accounts and try out your antispam program on them. Some day spam may be a thing of the past. In the
meantime, the only defense is constant vigilance, and the
best it can achieve is keeping the annoyance under control.
