The Edge Transport server role provides an important layer of security between the Internet and an organization’s messaging environment. Rather than having messages go straight from the Internet directly into an Exchange server, messages first go to an Edge server and are assessed and filtered based on certain policies or rules. The Edge server analyzes messages and can identify spam, content, connection trends, and take the appropriate action to prevent delivery of potentially harmful content, spam, and other undesired messages. The Edge server plays an important role in the messaging infrastructure, protecting the organization from attack, data leakage, and the delivery of unnecessary email, which ultimately can save an organization’s reputation, reduce administrative overhead, and increase productivity. Ensuring the delivery of legitimate messages is just as, if not more, important than filtering out unwanted messages. The Edge server addresses this need by providing advanced controls and configuration options to ensure the delivery of legitimate email and assist administrators in troubleshooting.
