How Spammers Abuse Whois and SMTP Part 3

In Part 3 of How Spammers Abuse Whois and SMTP, we will demonstrate the trivialities of sending Spam using SMTP. We will actually connect to an SMTP server and run commands to send a spam email to the server, which as we will see it gladly accepts. Of course, we will be using a locally setup SMTP server for this demo. We would also like to caution you against trying this out against real email servers on the Internet, as sending Spam is a punishable crime in most countries.
