I would also see research who Rogers Cable Inc. Pr is. If their legit, as in not shady, you can report it to their abuse department(assuming they have one) Also depending on your isp you might be able to report the abuse from the sending ip. They might ban them from your entire domain if there are enough reports. This is a scam email. I know people use those accounts on the fly and they have never mentioned any security feature like that.
