Fighting Spam in the Academic Arena

For the business and educational environments, spam has become a security issue. Junk e-mail has gone from just being annoying to being expensive and risky.

It has become an issue that can no longer be ignored; an issue that needs to be addressed in a multi-layered approach: at the source, on the network, and with the enduser.
