Take Back Your Inbox
By William G. Schwab
In this world everyone with e-mail faces spam. There is unwanted e-mail offering to help you do everything from assisting with a $30 million Nigerian problem to getting the lowest interest rate to making you “bigger.” In fact, over 40 percent of all e-mail is unwanted and unrequested.
Most people receive spam because they have taken some action on the Internet that “publishes” their address to the world. Knowing how junk mailers find your address makes it easier for you to prevent it in the future. Here’s a list of the hows.
Seven Risky Practices
One type of spam you can’t prevent is a dictionary attack. Have you ever received junk e-mail where your address appears in alphabetical order with others? This is accomplished through the use of two dictionaries: one of commonly used names, and one of known domain names.
Another method of spamming that is virtually unstoppable, because users usually don’t know it’s happening, are e-mails that come to you in HTML format. The graphics are not actually “in” the e-mail; however, they reside on a computer somewhere on the Internet, and are downloaded into your e-mail when you open it. To get to you, the spammer simply puts a code into an image file. When the e-mail is opened, the code is sent back, telling the spammer that he (or she) has found a valid e-mail address. Not even the Preview Pane feature of Outlook can help you; the image is downloaded there, too.
Finally, one of the best ways to assure your permanent position on a spammer’s list is to reply to an unwanted e-mail. Although many bulk e-mailers will respect your “unsubscribe” request, the more unscrupulous spammers will view your request as proof of a valid e-mail address. And to spammers, there’s nothing more valuable than a good e-mail address. So unless you know the vendor’s reputation, resist the urge to hit Reply.
How do you stop spam? There’s the delete key. Unfortunately, mass deletes can sometimes lead to the trashing of legitimate e-mails.
Today’s current technology cannot stop spam from invading your inbox. Spammers are constantly coming up with new ways of getting their message out, and so-called “spam filters” are having a hard time keeping up. In fact, recent surveys indicate that while only about 25 percent of spam gets blocked by software or blacklists, over 35 percent of legitimate e-mail is also blocked by these services.
Most ISPs and e-mail programs contain built-in spam filters, but in general they are weak and ineffective against today’s tough new breed of junk mail. Each program uses slightly different technology to accomplish its task. Some programs check messages against blacklists, which are public catalogs of known spammers. Others look for words or phrases that junk e-mailers routinely use, while still others examine the headers of each e-mail. Many spam-fighting tools utilize a combination of these methods.
Common software products include the following: SpamNet, MailWasher, Habeas, MailShell, ChoiceMail, SpamKiller, SpamCop, and SpamGourmet. These programs are fairly effective at eliminating a lot of the spam, but none of them is a substitute for good old-fashioned common sense. By practicing good spam-busting habits, you will make your e-mail address an unwelcome target for a spammer.
Remember, never reply to spam. By doing so, you provide to the spammer the information that your e-mail address is valid. Often, the address you reply to does not even exist, so your attempts to “unsubscribe” may be fruitless.
