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.
