The Edge Transport role The Edge Transport role is typically deployed in your perimeter network, outside your internal Active Directory forest, and is designed to minimize the attack surface of your Exchange deployment. By handling all Internet-facing mail flow, it also adds additional layers of message protection and security against viruses and spam, and can apply transport rules to control message flow. Internet mail flow All messages sent to the Internet from inside the organization are routed to Edge Transport servers after the messages are processed by the Transport service on the Exchange 2019 Mailbox server. Antispam protection In Exchange 2019, antispam features provide services to block unsolicited commercial email (spam) at the network perimeter. Edge Transport rules Edge Transport rules are used to control the flow of messages sent to or received from the Internet. Edge Transport rules are configured on each Edge Transport server to help protect corporate network resources and data by applying an action to messages meeting specified conditions. Address rewriting Address rewriting presents a consistent email address appearance to external recipients. You configure address rewriting on Edge Transport servers to modify the SMTP addresses on inbound and outbound messages.
