我正在使用javamail api制作一个自动发送电子邮件java项目。当我使用smtp.gmail.com主机发送此邮件时，它的工作原理。但是当我使用自己的主机服务器mail.sitename.com时...它显示异常..我的用户名和密码是正确的。请有人帮我解决这个问题......
例外情况是： -

代码：---
a)我正在使用DAO模式获取(电子邮件ID)目的的数据
b)一个jsp文件，用于启动和限制以获取与我将要发送电子邮件的连接的连接数。
c)Servlet文件如下所示......

我已经尝试了评论中的所有内容，但没有任何效果。我阅读了很多stackoverflow示例，没有人正确解决它。
