Use GFI Mail Security to monitor email messages for dangerous, offensive or confidential content . 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 MyDoom worm). Products that perform single vendor anti-virus scanning do not provide sufficient protection. 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. Products restricted to a single anti-virus engine will not protect against email exploits and attacks of this kind.
