Junk mail<br />

Junk mail, also called spam, is one of the curses of modern society. Spam is email<br />

messages that you never asked for, unsolicited commercial mail distributed to many<br />

people simultaneously. Typically, they contain advertising of some product, service,<br />

business, scheme, Web site, etc. Sometimes, such mail promote political ideas.<br />

Junk mail takes time to retrieve, browse, and delete, one by one. It distracts. For<br />

some, it may grow out of proportions, and become a major nuisance. Most users must<br />

pay to receive it, to a local phone company or an Internet service provider.<br />

What to do? If you get on someone's mailing list, you can ask the sender to take<br />

you off that list. This may help a little, but not much! <strong>The</strong>re are too many spammers out<br />

there. Besides, now the unscrupulous sender will know that your address is valid, and<br />

you will undoubtedly received more of the same!<br />

Personally, I delete them, and keep quiet. My communications costs are low, and it<br />

takes too much effort to get off that list.<br />

Others go a long way to protect themselves by being wary of giving out their email<br />

addresses, and of subscribing to newsgroups and mailing lists. However, sadly enough,<br />

the only 100 percent effective method is to close your mail account, and open another<br />

one. <strong>The</strong>n you should safe, but only for a while...<br />

If you're at all active on the net, your address will be picked up by spammers. It's<br />

so easy! Programs like Email Magnet can scan Web sites, newsgroups, and chat<br />

channels to retrieve any string looking like an email address.<br />

When you buy online or ask for information about something, your email address<br />

usually ends up in a database. Many online vendors sell their collection of addresses to<br />

others with information about what browser you are using, the domain you are calling in<br />

from, etc. Others consolidate your data with information from hundreds of other<br />

databases, each having some other bits of information about your use of the net,<br />

preferences, buying habits, etc.<br />

List brokers offer megabytes of lists or CD ROMs full of addresses to anyone<br />

willing to pay. Organizations and individuals offer to send spam mail to names in their<br />

private databases. For a fee, of course.<br />

Filtering is option. Most modern email programs have a filtering function that lets<br />

you automatically send spams to Trash. <strong>The</strong>y'll filter out mail from given senders, and if<br />

they find certain strings in the subject title or the body of the text.<br />

Example: Some dangerious virus distribution schemes are set to send dangerous code in<br />

seemingly empty messages. <strong>The</strong>y exploit a hole in the way .html is being displayed in email<br />

messages.<br />

To delete mails that are obiously hostile, I let my email program (Eudora Pro) search<br />

the body of the incoming mail for the string , and send them<br />

directly to trash.<br />

Another filter searches headers of incoming mails for aol.com (some hostile mails<br />

have this in common), and marks mails containing this string red in the list of incoming<br />

mails. In this way, it is easy for me to delete mails that are evidently unimportant, or if<br />

needed, to investigate their contents in a more careful way.<br />

Finally, consider using non Microsoft email programs like Pegasus Mail or Eudora<br />

Lite (both are free. This will make you less exposed to these risks. Don't open unlikely<br />

looking mail, like a message from the tax man with the subject "I love you". It almost<br />

certainly contains the infamous "I love you" virus. Don't forget that you can get viruses in<br />

attached Microsoft Word documents, too.<br />

Spam stoppers are used to prevent hostile software to pick up your email address from<br />

Usenet newsgroup. A spam stopper is additional characters that makes your address<br />

invalid while making it possible for real users to find out what your real address looks<br />
