You use six tabs to configure the Simple Mail Transfer Protocol (SMTP) virtual servers provided by Windows Server 2008 SMTP Server. The six tabs are described in the following table.

Tab Description


This tab contains settings that determine how the virtual server connects to other SMTP servers to transmit and receive messages. It can also be used to enable logging.


This tab contains settings to require authentication and the use of Transport Layer Security (TLS), which is a type of Secure Sockets Layer (SSL) encryption for all protocols, and for all incoming connections. You can also grant or deny both general and relay access to specific computers or networks.


This tab configures message limits and determines how to manage undeliverable messages.


This tab contains settings that determine how the virtual server delivers messages, including the number of messages sent per connection, how the virtual server routes messages, and retry intervals and expiration time-out for attempts to resend messages.

LDAP Routing

This tab contains settings for Lightweight Directory Access Protocol (LDAP) that allow access to directories that comply with the X.500 directory structure.


This tab designates the user accounts that have operator permissions to configure the SMTP service.
