Fighting Spam by Benny C. Rayner on 04/09/06

Have you ever had an e-mail account that hasnít been used for a while? When you think to check this e-mail account, do you have e-mails from random people and places? You have been spammed! Anyone and everyone can attest for these malicious, agitating, self-replicating e-mails. Although e-mail is an important and popular means of communication, spam is a nuisance as it accounts for over half of all e-mail sent each day.

Spam, also known as junk e-mail, can come to have many definitions. Spam can be unsolicited e-mail, often of a commercial nature, sent to multiple mailing lists, individuals, or newsgroups. Chain letters can be spam. The most infamous example is any variation on ďMake Money Fast!Ē but there are others that donít involve money. The ones that do are a felony (mail fraud) in addition to being a form of spam (Mansker, 1999). Spam can also be off-topic or inappropriate posting. This can be either to a mailing list or to a newsgroup. An example of this form of spam is posting a message concerning your litter of kittens on a mailing list devoted to NT security updates.
