This script monitors an FTP server and sends an email if it is not accepting connections. Many cell-phone providers provide SMS text to email gateway servers that you can use to send a text message if the server is down. The outbound email configuration for "mail.local", including Server, Port, Protocol, From, and To are all set in the Outbound E-Mail section of the Configurator.
