The Radicati Group's latest study, "Anti-Spam Market Trends, 2003-2007" provides market size, four-year forecasts, technology trends, regulatory information, and competitive data for the anti-spam
market. The study projects that if nothing is done to stop spam, the worldwide losses for companies, in terms of additional servers they have to deploy and manage to process spam, will amount to $20.5
billion in 2003, growing to $198 billion in 2007. In 2003, a company of 10,000 users with no anti-spam protection will spend, on average, $49 per mailbox per year processing spam messages. With prices
for anti-spam solutions starting at $15-$20 per user, ignoring the problem is hard to justify. A major corporate survey, conducted for this study, revealed that 94% of companies consider spam to be a
very serious problem; however, 43% still don't have a formal anti-spam policy in place. According to the study, revenues for anti-spam vendors and outsourcers are expected to approach $653 million by
2003, growing to over $2.4 billion by 2007.
