White Paper Abstract:
Once considered little more than an annoyance, spam has become an enormous problem affecting Internet users and broadband service providers. Well-known viruses, worms, and Trojan horses get the headlines, but spam is arguably a more pervasive and insidious threat because it affects every Internet user-directly or indirectly-and it lacks a comprehensive solution analogous to antivirus software programs. Spam frustrates users by overloading their e-mail boxes with volumes of useless and unwanted messages.
