这是部分代码：

return false;
}
//尝试连接smtp服务器并发送邮件....

} --------------------编程问答-------------------- 第一句话就报出来了错误，不能连接到126邮箱服务器 --------------------编程问答-------------------- 服务器连接有问题，试试163和qq的 --------------------编程问答-------------------- 为什么126的会还有问题呢？ --------------------编程问答-------------------- 设置错了呗 ！！！ --------------------编程问答--------------------
设置应该没什么问题
--------------------编程问答--------------------
把：Host=rs.getString(5);
User=rs.getString(6);
Pass=rs.getString(7);
Address=rs.getString(8);
改成：
Host="smtp.163.com";
User="user";
Pass="pass";
Address="xxx@xx.xx";
连接服务器都连不了，说明你的数据有问题，还有就是，你要确保邮箱已开通了smtp，pop3服务 --------------------编程问答--------------------
嗯，我也才是刚发现这个问题，我的win7是家庭版的，貌似没有ISS这个东西，除了升级外还有什么办法能开smtp？ --------------------编程问答--------------------
开通邮件收发服务，跟你是什么系统没关系啊，是邮箱服务商的，比如，163，你要登录邮箱去设置，有些是默认开通的，有些你要自己去开通，我印象中，QQ，新浪邮箱都要自己去开通。 --------------------编程问答-------------------- 126的是最好连的
如果126的都连不上
其他的就更难了 --------------------编程问答-------------------- 看了看
你这个是没有认证的结果
需要到邮件服务器认证 --------------------编程问答-------------------- 你再加一句：props.setProperty("mail.transport.protocol","smtp"); --------------------编程问答--------------------
请问怎么去认证呢？在网上没搜到相关的额 --------------------编程问答-------------------- 还是没弄出来，有人会么？ --------------------编程问答-------------------- 我是用spring集成的JavaMailSender来发送邮件的, 感觉简单点 --------------------编程问答-------------------- 额，目前还没朝spring方面弄，嘿嘿，不过还是谢谢你 --------------------编程问答-------------------- 不是你程序的问题，是因为你所在的网络连接不到smtp.126.com --------------------编程问答-------------------- 嗯，程序我也看不出什么问题，但是，因为是初学，所以也不知道怎么设置，求指教.....嘿嘿
补充：Java , Web 开发
