发邮件的程序中 javax.mail.AuthenticationFailedException异常的处理

在Java中，通过程序发送QQ邮件时，报：javax.mail.AuthenticationFailedException

这是身份认证的错误，这个时候，需要从以下两方面着手（实际验证过的）：

一、检查QQ邮箱或者别的邮箱是否开通了pop3/smtp服务，这个错误是认证失败，所以很有可能是没有开通pop3/smtp服务(需要开通，开通方式：https://blog.csdn.net/qq_35624642/article/details/72853055)，我在这里犯了两个错误，一是mail.password我错写的是邮箱登录密码，正确的应该写为开通pop3/smtp服务时的验证码；二是没有开通pop3/smtp服务。

            final Properties props = new Properties();
 
            props.put("mail.smtp.auth", "true");
            props.put("mail.smtp.host", "smtp.qq.com");
            //你自己的邮箱
            props.put("mail.user", "[email protected]"); 
            //你开启pop3/smtp时的验证码
            props.put("mail.password", "xxxxx");
            props.put("mail.smtp.port", "25");//465也可以的

 

例如实际的主要配置信息：

    
    
    
    
    
    
    
    
    
    
  

二、在用户名、密码都没有问题以及pop3/smtp服务也开通的情况下，还是报这个错误，先登录一下邮箱，测试是否能正常发送邮件。
有时候邮箱发送邮件过于频繁，可能被网站认为是恶意软件攻击，这个时候就需要定期去他们的网站登录一下，处理一下

三、还要注意一点，配置的时候一定要有：mail.smtp.auth=true
