通过 zoho 发送 SMTP 邮件时出现连接超时错误

Question

当我尝试通过 SMTP 发送 django 邮件时出现连接超时错误。以下是我的配置 -

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
# Host for sending e-mail.
EMAIL_HOST = 'smtp.zoho.com'
# Port for sending e-mail.
EMAIL_PORT = 587
# Optional SMTP authentication information for EMAIL_HOST.
EMAIL_HOST_USER = '[e-mail]'
EMAIL_HOST_PASSWORD = 'amaze123'
EMAIL_USE_TLS = True

我使用的代码是：

    from django.core.mail import send_mail
    >>> send_mail('Order Confirmation', 'Order placed successfuly', 
'[e-mail]', ['[e-mail]'])

错误-

是否确实

需要使用 TLS 而不是 SSL，如果需要，是否在电子邮件帐户上启用 smtp？
