The Design And Implementation Of A Mobile Phone Management System Of Mail With Filtering

With the global development of the Internet and information technology advances, as well as network technology, innovation, mobile terminals, wireless devices are becoming more popular, the smart phone has become a mainstream communication tool for mobile e-commerce Today, e-mail service as the most a wide range of applications, its convenient facilities, fast operation will attract more and more mobile phone users. However, as mobile e-mail services and the increased popularity of its security issues become more serious, not only e-mail system security can not be guaranteed, and even e-mail system has also become a breakthrough in mobile phone operating system invasion spoilers. Therefore, the development of e-mail with an e-mail filtering management system research has important practical significance.This paper studies the realization of a J2ME-based e-mail management with a filtering system, filter set up inboxes and trash, while the new incoming mail using Bayesian classification algorithm to determine the normal e-mail, or spam. In the filter in the addition of black and white list of features, and mobile phones through the Bayesian algorithm to filter combination of black and white lists to identify e-mail. Sending and receiving messages to move the rules-based, Web Mail server back-center, from the e-mail account settings, mail and close friends to save the starting address, sub-module for the entire system. Full text of more complete and clear introduction to the Java-based J2ME mobile phone software - mobile e-mail system, the theoretical value and practical value, J2ME architecture and related basic theories, JavaMail API, system design and implementation and related key technologies. Paper first describes in detail the basis for developing mobile applications, the main function of the theory-J2ME and architecture. Secondly, according to papers the design goals, given the system design plan, the system processes, and to explore the system to achieve the needs of key technologies and the need to solve the problem. Server in the middle of the design and implementation, the system uses the Servlet technology, and technology as a middle layer of JavaMail, solving technical problems sending and receiving e-mail.At last the mobile client MIDP design. MIDP client is a major e-mail access devices, functional modules including the system parameter settings, send e-mail, receive messages, forwarding messages, replying to messages, as well as friends address book, the system help. Paper uses a number of technology MIDP client, such as the J2ME advanced interface API, J2ME permanent record storage.
