基于JavaMail的电子邮件系统的设计与实现 邮件系统的设计与实现 摘 要 　　　在过去的几十年里，人们主要通过书信与相隔较远的人相互交流情感与思想。而当今世界人们更多的是使用电子邮件，与传统的书信相比，电子邮件具有使用简易、投递迅速、收费低廉，易于保存、全球畅通无阻等优点。 　　　本文设计并实现了一套邮件系统。首先研究了与系统相关的技术，其次分析了系统功能、性能和数据的需求，设计了系统构架、系统功能和数据库，并实现了系统的主要功能。本文的系统构架是基于浏览器/服务器的三层架构，使用Java和S2SH框架开发而成。在数据存储上使用了免费、开源、跨平台的MySQL数据库，邮件服务器使用了免费、开源的支持SMAP协议发送电子邮件和IMAP协议接收电子邮件的Apache James邮件服务器。通过系统设计的用户注册和登陆、用户信息管理、邮件管理等模块，对邮件系统进行实现。 　　　本系统具有功能丰富、结构清晰、运行效率高、数据访问效率高等优异性能，后期易于维护，可扩展性行比较好。 　　　本系统还存在以下几个方面的工作尚需完善，即增加联系人管理模块，增强系统的稳定性，增强系统的安全性。 关键词：电子邮件，James邮件服务器，MySQL，Java，S2SH Mail System Design and Implementation Abstract 　　　In the past few decades, people mainly exchange ideas with each other by letters.?But today people are communicating with each other via e-mail, compared with the letter, e-mail correspondence with easy to use, fast delivery, low-cost, easy to store, the worlds smooth and so on.? 　　　This article has designed and implemented a mail system. First , study technologies related to the system. Then , analyses the system functions, performance and the data requirements, and also design the system architecture, system functions and database, and finally the main functions of the system come into shap . The system architecture is developed basing on a three-tier browser / server architecture, using Java and S2SH framework. The Data storage take use of free, open-source, cross-platform MySQL database. The mail server use the free, open-source Apache James mail server that supports SMAP protocol to send e-mails and the IMAP protocol to receive e-mails. Develop the E-mail system by different module of the system design, including user registration and login, the user information management, mail management. 　　　This system has the feature-rich, clear structure, high efficiency, excellent performance of high efficiency of data access, and it is not only easy to maintain in latter stages but also outstanding in it`s scalable sexual activity. 　　　There still exists problems that need farther perfection in
