Active e-mail system SMTP protocol monitoring algorithm

E-mail system is one of the most ubiquitous Internet-based applications today. It enables users to send and receive e-mail messages among each other within and from outside of the local area network. E-mail system is used every day in almost all organizations as a communication tool between managers, employees, customers, and partners for better information flow and conduct business which requires communication with people outside the organization, or from different geographical locations. The e-mail system offers a fast, reliable and easy solution for such communication. SMTP (simple mail transfer protocol) is a transportation protocol used to transfer e-mail messages over the Internet. All e-mail servers use the SMTP to send e-mails from one e-mail server to another. SMTP is also used to send e-mail messages from e-mail clients to e-mail servers. In this paper, the SMTP e-mail system protocol will be briefly explained. New active monitoring algorithm architecture is also proposed to improve the current e-mail system protocol functions and detect the SMTP protocol failure during the process of sending e-mail messages.
