This isn't really hacking, it's just using a mail server, for sending mail... The problem is/was that SMTP AUTH was overlooked as a requirement from the original SMTP spec, and the bigger WTF is that it took about 20 years before it was added to the spec. Edit to add: "While he was on the computer I shut off all the power on the floor." - Because everyone can just stand there and shut all the power off on a floor... if it were indeed a 'hack' then give more specifics, if it's flipping the switch on a breaker... well... that's just that.
