Discuss the issue with sending messages in clear text.
What will be an ideal response?
Messages sent via e-mail are transmitted in clear text. This means that there is no encryption or other encoding used to hide important information, such as the username and password of the e-mail account. If you dig through a packet capture of an e-mail transmission, you can easily locate these items in the USER and PASS command captures. E-mail can be secured using two different types of encryption methods (Secure MIME via public-key encryption or Pretty Good Privacy).
