我正在使用javamailapi制作一个自动发送电子邮件的java项目。当我使用smtp.gmail.com主机发送此邮件时，它可以工作。但当我使用我自己的主机服务器mail.sitename.com时…它显示异常。。我的用户名和密码是正确的。请任何人帮我解决这个问题。。。例外情况是：-

a） 我使用DAO模式获取数据以达到（电子邮件id）目的b） 一个jsp文件开始并限制获取与我要发送电子邮件的人的连接。。c） Servlet文件如下所示。。。

我也尝试了所有评论中的内容，但都没有效果。我读了很多stackerflow的例子，但没有人能正确地解决它。
得到了解决方案。。。。有时javax.mail.AuthenticationFailedException：535身份验证失败（#5.7.1）发生在主机未使用代码对用户进行身份验证达到限制时。。。我打电话给主机，在一个程序运行时向大约500名用户发送邮件。所以sendMail（）调用了500次，结果服务器挂起了。因此，它阻止了我对编码网站的身份验证，但可以使用浏览器访问。当我创建一个新帐户时，我找到了解决方案，然后在编码时，我创建了一个线程，通过该线程，sendMail（）将每隔10秒调用一次，然后一次发送给100个用户。主机来自网络解决方案的电子邮件登录。希望我能给别人解决这类问题的办法
如果您使用电子邮件的gmail帐户（SMTP），请确保application.properties文件中有正确的电子邮件密码，并启用此设置允许您的gmail帐户使用不太安全的应用程序。
在一个项目中，我需要发送一封带有附件的电子邮件，其中包含可以在不同的客户端机器上生成的测试结果，我使用了以下属性和代码（这些属性被翻译为设置对象中的字段，在下面的代码中提到）
