eWall is a Microsoft Windows based gateway (or sometimes referred to as SMTP proxy) between the Internet and your mail server. It monitors the SMTP traffic in real-time and protects the mail server, catching the majority of spam and viruses. The chain of flexible filters stops more than 95% of unwanted emails out of the box (more than 99% with Message Sniffer), dropping the mail server load by more than 90%.

eWall doesn't require maintenance and includes optional self-updating components (ClamAV, Message Sniffer), that seamlessly work with and protect your mail environment from spam and viruses 24 hours a day, 7 days a week.
