jsp+servlet实现邮件收发系统

大家好，我正在做一个基于jsp的邮件收发系统，有哪位好心人可以发个源码借鉴一下，必有重谢！

邮箱号码875560133@qq.com

String username="发件邮箱账号";
String post="xtybzusnjecvbcbc";//登陆qq邮箱每次登陆，它生成的码
String registerId = "" + Math.random() * Math.random();

String url = "http://localhost:8080/loginemail/servlet/MailBackServlet?registerId=" + registerId;
HttpSession httpSession = request.getSession();
httpSession.setAttribute(registerId, name);
httpSession.setMaxInactiveInterval(600);
Properties props = System.getProperties();
props.setProperty("mail.smtp.host", "smtp.qq.com");
props.setProperty("mail.smtp.auth", "true");
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
props.put("mail.smtp.socketFactory.fallback", "false");
props.put("mail.smtp.starttls.enable", "true");
Authenticator authenticator = new MyAuthenticator(username, post);
Session session = Session.getInstance(props,authenticator);

session.setDebug(true);

try{

Address from = new InternetAddress(username);

Address to = new InternetAddress(email);

          MimeMessage msg = new MimeMessage(session);  
           msg.setFrom(from);  
           msg.setSubject("*********");  
           msg.setSentDate(new Date());  
           msg.setContent("点击<a href='" + url + "'>" + url + "</a>完成注册！", "text/html;charset=utf-8"); //发送给你邮箱里的内容
           msg.setRecipient(RecipientType.TO, to);  

            我这个代码是邮箱验证时候的代码，你的收发邮件和这个差不多，原理都是一样的，邮箱账号的话，前台可以运用jsp文本框输入，然后跳转到这个servlet代码页面，用request取出。其实很简单，你自己好好看看吧
