Anti-Spam Solutions and Security
In a recent survey, 93% of respondents reported dissatisfaction with the large volume of unsolicited email (spam) they receive. [ref 1] The problem has grown to the point where nearly 50% of the world's email is spam [ref 2], yet only a few hundred groups are responsible. [ref 3] 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.
