Spam Blocker Lite protects the network with advanced spam filtering techniques to weed out spam at the network gateway -- before it reaches the mailserver or desktops. Using the latest technologies, Spam Blocker transparently scans for spam, marks messages and intercepts emails. It requires no alteration of your network’s mail configuration and is constantly updated to provide continuous protection as spammers find new ways to evade filters.
Spam is the bane of small businesses’ existence. It wastes employee time, renders inboxes unmangeable and can even infect desktops with viruses and spyware. The impact that spam has on productivity is astounding. According to a recent study, the cost of spam messages to U.S. companies -- in terms of productivity and the equipment, software and manpower to combat it -- was upwards of $10 billion in 2004.
The key is to stop spam before it stops you.
