3. Sending your first email from your Raspberry Pi using Telnet

In this second technical video in the video series, I explain how to test your email setup (specifically your SMTP server in this case), using the Telnet utility. I will first explain why we are doing this, and how to install and use Telnet. By the end of this video you will be able to send an email as anybody to anybody, a powerful idea, which will hopefully frame the picture that sending an email as a 'legit' email server is tricky, and requires special attention which we'll get to at the end of this series.
