DOCUMENT:Q259531 17-JUN-2002 [exchange] TITLE :XFOR: How to Configure SMTP Relay for Domains and Subdomains PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5 OPER/SYS: KEYWORDS:kbenv exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SUMMARY ======= You can use Internet Mail Service to relay mail for multiple Simple Mail Transfer Protocol (SMTP) domains and their associated subdomains to a specific smart host. This option is made easier by the default routing property of Internet Mail Service to accept all mail for a domain unless the domain is explicitly designated by using a number sign (#) before the main domain. For example, an inbound domain of #microsoft.com only accepts mail for the microsoft.com domain, whereas microsoft.com accepts mail for all domains in the namespace of microsoft.com. MORE INFORMATION ================ To configure SMTP relay for domains and subdomains, use the following steps: 1. Open Internet Mail Service properties. 2. On the Connection tab, click E-Mail Domain, and then click Add. 3. In the E-mail Domain field, type the namespace for the domain to be relayed. NOTE: By default, all subdomains are also relayed. 4. Click "Forward all messages for this domain to host", type the fully qualified domain name (FQDN) or the Internet Protocol (IP) address of the target host, and then click OK. 5. On the Routing tab, click "Reroute incoming SMTP mail", and then click Add. 6. In the "E-Mail sent to this domain" field, type the namespace for the domain that needs to be relayed. 7. Click "Override relay restrictions. Always relay.", and then click OK. 8. Restart Internet Mail Service when you are prompted to do so.
