This article describes how to configure a remote domain for an Internet Information Services (IIS) Simple Mail Transfer Protocol (SMTP) mail relay server.
IIS in Windows Server 2003 includes a full-featured SMTP virtual server that you can use to route mail on your internal network. The SMTP virtual server can also accept mail from the Internet. Although the SMTP Service does not include an easily accessible mechanism in which to retrieve mail, it can play a vital role in accepting mail from the Internet and relaying it to your SMTP/POP3 server. You can configure the SMTP virtual server to accept mail for the domain to which the computer belongs, and for other domains.
A stand-alone server that is running the SMTP Service provides a good measure of security because it acts as a layer of separation between the corporate mail server and inbound connections from the Internet. A stand-alone Windows Server 2003-based computer isolates the server from the Active Directory security boundaries of the internal network. You can configure the stand-alone SMTP virtual server to use the corporate mail server as a smart host. You can then configure the stand-alone SMTP virtual server to relay mail that is directed only to the remote domain. If you do this, all other mail is not relayed and is rejected.
