But a poorly implemented filter can remove important messages, which could cost you more than a barrage of useless email.
An email filter is software that scans messages for undesirable content, from annoying "make money fast" messages to hostile viruses.
A filter can be installed on your company's LAN or work as an outsourced service. Filters range from simple to sophisticated; a basic filter scans for spam and viruses, while a more sophisticated filter can search for other criteria such as pornography or confidential business information.
Spam filters are a good thing, but system administrators need to implement them with care. If filters are too stringent, they can stop legitimate email in its tracks; too lax, and spam and viruses will sneak through.
