What is spam? The dictionary definition is “unsolicited junk email – generally advertising some product sent wide-scale to a mailing list or newsgroup”. But that is just a broad definition, open to interpretation; one man's spam is another man's newsletter. If you ask an end-user, they will often define spam as “mail I don't want” – very precise from that particular user's point of view, but not implementable in a shared computerized system. There is a significant gray area concerning spam, though it is possible to provide a working test for whether a message is spam or not, and lay the foundation for implementing effective protection against this nuisance. Read this white paper to find out if you are adequately protecting your network against spam. |
