In this lecture, learn about a protocol flaw in ESMTP that can be used against spammers. As we walk through the technical underpinnings of SMTP and the creative process of discovering and exploiting a flaw in the protocol, we'll also learn about the various types of Scotch whisky consumed while working on the technique. -Presented by Jonlin.
