Anti-spam solutions and security

Friday, 27 February 2004, 1:29 AM EST

In a recent survey, 93% of respondents reported dissatisfaction with the large volume of unsolicited email (spam) they receive. The problem has grown to the point where nearly 50% of the world's email is spam, yet only a few hundred groups are responsible. Many anti-spam solutions have been proposed and a few have been implemented. Unfortunately, these solutions do not prevent spam as much as they interfere with every-day email communications.

The problems posed by spam have grown from simple annoyances to significant security issues. The deluge of spam costs up to an estimated $20 billion each year in lost productivity -- according to the same document, spam within a company can cost between $600 and $1,000 per year for every user.
