Django smtpserverdisconconted pyspess Reset上的错误(但在其他地方起作用)

Question

我正在尝试在Django设置上设置自助密码。我已经将其配置为使用内置的密码重置系统，并测试了Dev Machine上的所有内容，并且正常工作。但是，在生产中（即实际发送电子邮件），当我尝试获取密码重置电子邮件时，它会引发一个smtpserverdisconconted错误：

SMTPServerDisconnected: Connection unexpectedly closed

我正在使用G-Suite（Google）作为SMTP继电器；我正在使用的设置是：

EMAIL_HOST = 'smtp-relay.gmail.com'  
EMAIL_PORT = 587                     
EMAIL_USE_TLS = True

奇怪的是，我可以使用Django的django.core.mail.send_mail（）函数在系统内其他位置发送电子邮件。

Answer 1

问题是我没有设置Default_from_email，因此Django试图从Localhost电子邮件地址发送，Google的SMTP服务器被默默拒绝。在Send_mail（）的其他用途中，我已经指定了来自地址的来自地址。
