IoT Data Access via Email System using POP3 Protocol

Internet of Things (IoT) is the set of technologies enabling the interconnection of objects by uniquely identifying them in the network. These objects can be provided with sensors/actuators and can easily make information available or perform complex actions. For connecting these things, we need a common platform for communication. Email system can play a vital role when we want secure communication in the world of IoT. Communication between email servers and clients are governed by email protocols. Four important protocols used in email communication are IMAP, POP3, SMTP and HTTP. This paper will focus on POP3 which is designed to support offline/local email processing. Email is delivered to a mail server and a remote email client regularly downloads the email from the server to the user's computer. Once the messages are delivered, they are deleted from the mail server, although users can configure their email client to leave a copy of the email on the mail server.
