相信看到535报错的同学代码编写方面都没有问题，只是不明白为什么填写了帐号密码后还是报535错误，使用网易的126或者163邮箱都会有如此问题。
Python报错如下：
代码语言：javascript复制Traceback (most recent call last):
File "mail.py", line 18, in <module>
smtp.login( username, password )
File "/usr/lib64/python2.6/smtplib.py", line 589, in login
raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, 'Error: authentication failed')Java报错如下:

Caused by: javax.mail.AuthenticationFailedException: 535 Error: authentication failed如果你利用网易邮箱发送邮件password字段配置成登录用户密码的时候，经常会遇到如上错误。
解决方法如下:
调用网易邮箱服务器来发送邮件,我们需要开启POP3/SMTP服务,这时网易邮件会让我们设置客户端授权码，这个授权码替代我们设置发送邮件用户的password即可成功发送邮件, 设置流程如下：
按照如上如1 2 3 4 5 6的顺序设置客户端授权码，设置完成后把你配置的password的值替换成你设置的客户端授权码，例如我上面设置的是test123, 如果你想重置授权码的话，如下图所示：
