Configuring SMTP Virtual Servers
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1
There are two identifying features for a Simple Mail Transfer Protocol (SMTP) virtual server: the display name and the IP address/TCP port combination. Setup assigns a Microsoft Management Console display name for the default SMTP virtual server. You can keep the name (Default SMTP Virtual Server) or change it using the following steps. You can also select the IP address that will be associated with this SMTP virtual server.
Important
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /User:Administrative_AccountName "mmc systemroot\system32\inetsrv\iis.msc".
Procedures
To identify an SMTP virtual server
In IIS Manager, right-click the SMTP virtual server, and then click Rename.
Type a new name for the virtual server name if you want to change it from the default. Do not use extended characters when naming your SMTP virtual server.
Right-click the SMTP virtual server, and click Properties.
On the General tab, in the IP address list, click 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.
Note
When you change an SMTP virtual server's configuration, you may want to use the Pause command. Pausing prevents new client connections but enables Microsoft SMTP Service to continue to process existing client connections and deliver queued messages.
