我也尝试了所有评论中的内容，但没有任何效果。我读了很多stackoverflow的例子，没有人正确地解决它。

得到了解决方案。...有时javax.mail.AuthenticationFailedException：535验证失败（＃5.7.1）是在主机未使用代码对用户进行身份验证达到上限时发生的。一个程序运行500个用户，因此sendMail（）调用500次并使服务器挂起。因此，它阻止了我对编码站点的身份验证，但可以使用浏览器进行访问。当我创建一个新帐户，然后编码时，我想出了解决方案，然后创建了一个线程，通过该线程将以10秒的间隔调用sendMail（），然后立即发送给100个用户。主机来自网络解决方案电子邮件登录。希望我能给某人解决此类问题的方法。:)
