Completely blocking email attachments is one way to protect yourself from viruses, but that approach just isn't realistic for many companies.There is not a central place in Exchange 2003 to block attachments If you want to block inbound email attachments at the Exchange server, you have to rely on third-party software. So one of which i can suggest you is GFI MailSecurity.

GFI MailSecurity uses multiple anti-virus engines to scan inbound email. Using multiple scanners drastically reduces the average time required to obtain the latest virus signature, which means we're quicker to help you to combat the latest threats. The single engine approach will never be fast enough to respond in today's world. Each anti-virus software engine has a different response time to each new virus, depending on where the virus was discovered, and other factors. By using multiple anti-virus engines, we give you a much better chance of having the right software, at the right moment, to combat the latest attck. Since each engine has its own heuristics and detection methods, each one brings a its own strength to your email environment for detecting a particular virus and its variants. Multiple anti-virus engines means better virus protection. GFI MailSecurity give you better virus protection.
