Simple Mail Transfer Protocol (SMTP) virtual servers have two identifying features:

Setup assigns a Microsoft Management Console display name for the default SMTP virtual server. You can keep the name [SMTP Virtual Server #1] or change it by using the following steps. You can also select the IP address that will be associated with this SMTP virtual server.


To identify an SMTP virtual server

  1. In Microsoft Management Console, select the SMTP virtual server, and then click Rename on the Action menu.

    For instructions about how to start Microsoft Management Console, see Start Microsoft Management Console.

  2. Type a new name for the virtual server name if you want to change it from the default name.

    Do not use extended characters when naming your SMTP virtual server.
  3. Select the SMTP virtual server, and then click Properties on the Action menu.

  4. In IP address, select the IP address for this virtual server. The SMTP virtual server can respond to connection requests for all IP addresses configured on the computer. To identify the TCP port for each IP address configured for the virtual server, click Advanced. Port 25 is the SMTP standard TCP port and is recommended. More than one virtual server can use port 25, provided they are associated with different IP addresses.

When you change an SMTP virtual server's configuration, you may want to use the Pause command. For instructions about how to pause an SMTP virtual server, see Pausing an SMTP Virtual Server. Pausing prevents new client connections but enables the SMTP service to continue to process existing client connections and deliver queued messages.
