django - Django Zoho SMTPAuthenticationError（535，b'身份验证失败'）

问题描述

我正在使用 Django 的电子邮件后端发送帐户验证电子邮件。这是我的设置的样子：

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.zoho.in'
EMAIL_PORT = 587
EMAIL_HOST_USER = 'someone@example.com'
DEFAULT_FROM_EMAIL = 'someone@example.com'
EMAIL_HOST_PASSWORD = 'somepassword'
EMAIL_USE_TLS = True

直到几个小时前它突然停止工作时，此配置都可以正常工作，并引发此错误：

    raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (535, b'Authentication Failed')

我不确定是什么触发了错误，但现在它也不适用于其他主机帐户。我没有更改任何内容，我的 Zoho 帐户的 2FA 也没有激活。它停止工作的原因可能是什么？

解决方案

只是改变了这一行

EMAIL_HOST = 'smtp.zoho.in'

到这条线

EMAIL_HOST = 'smtp.zoho.com'

我仍然无法解决您的问题，这意味着您已在您的 zoho 帐户中打开了两因素身份验证。因此，请将其关闭或仅在 zoho 帐户中生成应用程序生成的密码并在您的代码中使用它。
