可复原WebMail的设计与实现

Design and Implementation of Recovery Oriented WebMail

目前,传统的WebMail只是在一些简单的邮件编辑功能上提供了复原功能,而对邮件本身的传输操作却没有提供复原功能,在传统的WebMail中邮件的流向是单向的,因而用户无法撤销或者重现一封已发送的邮件。文中针对该问题对邮件系统中的MUA(Mail User Agent),借鉴ROC回退技术思路,基于Struts框架和JavaMail技术,设计并实现了一个支持邮件双向流动的可复原WebMail系统,称为RO-WebMail.RO-WebMail强调用户对已发邮件的控制,用户可以按照复原规则对邮件进行双向控制(发送、撤销、回收),对邮件的可控性更高也更加灵活,从使用性来说对用户更为友好。

Nowadays,the traditional WebMail provides mail recovery functionality only on simple mail editing,and no recovery functionality for mail transmission.In the traditional WebMail,the flow of mail is mono-directional,thus the user could not cancel or reproduce a sent-out mail.In the light of recovery oriented computing（ROC） and MUA（Mail User Agent） in mail system,a WebMail known as RO-WebMai based on Struts and JavaMail is designed and implemented.RO-WebMail supports the bi-directional flow of mail,and places stress on the user＇s manipulation of the sent-out mail,the user could control the flow of mail according to the recovery rules,thus is more convenient and user-friendly.
