Basically you setup a rule in outlook to look for say a keyword in the subject line of an email. Then you select run application as the action for when that keyword is found. Then all you have to do is write a simple dos batch file and use the shutdown command with the -f parameter to ensure the shutdown is not aborted by any running applications. After that the rest is simple you simply send a sms text message from your cell phone or other source to your email address. You must have automatic send and receive tunned on for this to work.
