Introduction The need to monitor email messages for dangerous, offensive or confidential content has never been more evident. The most deadly viruses, able to cripple your email system and corporate network in minutes, are being distributed worldwide via email in a matter of hours (for example, the Love letter virus). Anti-virus vendors cannot update their signatures in time. Worse still, email is likely to become the means for installing backdoors (Trojans) and other harmful programs to help potential intruders break into your network. Anti-virus vendors will never protect against this. Your only defense is to install a comprehensive email security, content checking, and anti-virus gateway to safeguard your mail server & network.
