To use in anger:

Replace instances of pa55Word with a real password of your choosing.

Put the actual IP of your server running NUT into _server_IP_ in upsmon.conf

Substitute these lines in gmail.py with real values for the account you're using to send and the address you want to get alerts from.

gmailUser = '[email protected]'
gmailPassword = 'pa55Word'
recipient = '[email protected]'

Also note that you'll have to jump through some hoops with the sending gmail account to allow it to be used this way (as gmail has tightened up security defaults).
