1. Email Overview

The protocol that is defined to exchange email over the Internet is simple mail transfer protocol (SMTP). SMTP is used to send email to another email server which is then received through the procedure of post office protocol version 3 (POP3) or another procedure instant message access protocol (IMAP). It can be illustrated in Figure 1 that the email was send via SMTP, then authentication is handled by POP3 or IMAP. The authentication alone is unencrypted, to encrypt is to be send over secure socket layer (SSL) for more secure communication [1].

Another technology is the mailing list where the clients subscribes so they’re included into the mailing list. Materials will be send to the subscriber within the mailing list. Security issues on email other than malware mostly dealt with spams.
