解决方案

  1. 95% 成功率 
    Set EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' for development.
  2. 90% 成功率 
    For production: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' with EMAIL_HOST, EMAIL_PORT, EMAIL_HOST_USER, EMAIL_HOST_PASSWORD.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Setting EMAIL_BACKEND='' doesn't work; must be a valid backend path.

  2. 50% 失败

    Using SMTP backend without host/user/password fails at runtime.
