ZDNet: Interactive Week: Beware Of The E-Mail Joke Police.
A new e-mail monitoring system from SurfControl that is set for release in mid-April is able to watch incoming e-mail and block commonly reported jokes, hoaxes, spam and image attachments, as well as stop sensitive outgoing data.
The software scans incoming and outgoing messages, and can bar e-mail that contains keywords or phrases that a company selects. At that point, an Internet administrator or human resources manager with appropriate access rights can review the message and send it on, delete it or take other action.
