If you’re needing to do some SMTP testing using a Windows Server 2008 host you’re probably going to need a Telnet client.  The Telnet client is not installed by default on Windows Server 2008, so you can use this ServerManagerCmd.exe one-liner to quickly install it:

C:\>servermanagercmd -i telnet-client

Start Installation...
[Installation] Succeeded: [Telnet Client].

Success: Installation succeeded.
