The purpose of this video is to show an e-mail security flaw using telnet that allows hackers to send e-mails using anyone's e-mail address. Thankfully, many major e-mail providers have software that blocks this. My intention is to make people aware of this flaw so that other e-mail providers can protect themselves as well.
