SUMMARY
 * Creating a New SMTP Virtual Server with Internet Services Manager



SUMMARY
This step-by-step guide describes how to create additional Simple Mail Transport Protocol (SMTP) virtual servers.

In most cases, you need only one SMTP virtual server. However, if you are hosting multiple domains and want, for example, to have more than one default domain, you can create multiple SMTP virtual servers.

Creating a New SMTP Virtual Server with Internet Services Manager
When you create an SMTP virtual server, you are prompted to type a path to your home folder. This folder must be local on the computer on which the SMTP service is running. To create a new SMTP virtual server:  If the SMTP virtual server will use a new IP address, add an IP address by following these steps:  Click Start, point to Settings, and then click Network and Dial-up Connections. Right-click the connection you want to configure, and then click Properties. On the General tab or Networking tab, click Internet Protocol (TCP/IP), and then click Properties. Click Advanced. On the IP Settings tab, click Add in the IP addresses section. Type an IP address and a subnet mask under the IP address and Subnet mask headings, and then click Add.</li> Repeat step 1 for each IP address that you want to add, and then click OK.</li></ol>

See your Windows 2000 documentation for additional information about Network and Dial-Up Connections.

</li> Click an existing SMTP virtual server in Internet Services Manager, point to New on the Action menu, and then click Virtual Server.</li> Follow the instructions in the New SMTP Virtual Server Wizard. Make sure to select an IP address and TCP port combination that is not being used by another SMTP virtual server. The recommended TCP port is 25 (the SMTP standard TCP port). More than one virtual server can use the same TCP port if they are configured with different IP addresses.</li> If the default startup setting for the Microsoft SMTP service is set to Automatic, the new SMTP virtual server will start on its own. If it does not start, it is because you selected an IP address and TCP port combination that is already in use.</li> Configure the new SMTP virtual server.</li></ol>
