URLName urln = new URLName("pop3","pop3.10.40.15.45",110,null,"w75004","wanggeng");

pop3.10.40.15.45
直接写个邮件ip 或者pop3.163.com 之类的

props.put("mail.smtp.auth", "true");

登录邮件服务器的用户名和密码在什么地方设置的？？？
鉴权类应该继承Authenticator类。

 EmailAuthenImpl auth = new EmailAuthenImpl(userName, password);
            // 获得系统环境
            Properties ps = System.getProperties();
            // 设置登录邮件服务器的主机地址
            ps.put("mail.smtp.host", host);
            // 设置登录邮件服务器的主机端口
            ps.put("mail.smtp.port", port);
            // 设置邮件服务器的登录方式(必须通过授权)
            ps.put("mail.smtp.auth", "true");
            // 连接超时时间
            ps.put("mail.smtp.connectiontimeout", 30 * 60 * 1000);
            // IO超时时间
            ps.put("mail.smtp.timeout", 30 * 60 * 1000);
session = Session.getDefaultInstance(ps, auth);
