Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1

Lightweight Directory Access Protocol (LDAP) is an Internet protocol that enables you to access directory information from an LDAP server. With permission to use LDAP, you can browse, read, and search directory listings on the LDAP server.

With the LDAP Routing tab, you can configure the SMTP service so that it will consult an LDAP server to resolve senders and recipients. For example, you can use Active Directory directory service as an LDAP server, and use Active Directory Users and Computers to create a group mailing list that is automatically expanded on the Simple Mail Transfer Protocol (SMTP) virtual server.

This section describes how to configure the SMTP service as an LDAP client so you can gain access to directory information on an LDAP server.
