There's no getting away from Spam, latest reports suggest that every other e-mail you receive will be Spam and despite recent laws, it shows no sign of stopping. Spam wastes companies and individuals a tremendous amount of time. Each spam e-mail received has cost the recipient in terms of network bandwidth, computing power, and, most importantly wasted time. Studies have put the monetary costs of spam at up to $1,000 annually for each employee.
So what can be done about it? One of the most popular and effective ways of combating Spam is to install a Spam Filter and SpamAssassin is perhaps the best open source spam filter available today. See More
SpamAssassin was last week promoted to a Top Level Project by the Apache Software Foundation. See More
