谢谢！

解决方案

看起来您正在尝试发送邮件（ send_mail（））和您的 settings.py 中的设置/＃电子邮件主机rel =noreferrer>邮件设置是不正确的。

您应该检查文档发送电子邮件。

---

为了进行调试，您可以使用以下命令设置本地smtpserver：

  python -m smtpd -n -c DebuggingServer localhost：1025 
  

并相应调整您的邮件设置：

  EMAIL_HOST ='localhost'
 EMAIL_PORT = 1025 
  

这里记录了：测试电子邮件发送

作为启动专用调试服务器的替代方法，您可以使用 <$最近添加到Django的c $ c> console.EmailBackend 。

解决方案

Looks like you are trying to send a mail (send_mail()) and your mail settings in your settings.py are not correct.

You should check the docs for sending emails.

---

For debugging purposes you could setup a local smtpserver with this command:

python -m smtpd -n -c DebuggingServer localhost:1025

and adjust your mail settings accordingly:

EMAIL_HOST = 'localhost'
EMAIL_PORT = 1025

This is documented here: Testing e-mail sending

As an alternative to starting a dedicated debugging server you could use the console.EmailBackend which was added to Django recently.
