Python 使用Django时出现SMTPConnectError

我使用django注册来处理用户注册。我试图注册以测试它，测试后，我得到了这个错误

SMTPConnectError at /accounts/register/

正在试图找到解决方案，但没有成功

完全回溯

在Settings.py中

EMAIL_BACKEND='django.core.mail.backends.smtp.EmailBackend'

EMAIL_USE_TLS=True

EMAIL_HOST='smtp.test.com'

EMAIL_HOST_USER='test@test.com'

EMAIL_HOST_PASSWORD='f88lm'

EMAIL_PORT=587

DEFAULT_FROM_EMAIL = 'test@test.com'

SERVER_EMAIL = 'test@test.com'

当然有一个错误，您已经给出了SMPT服务器的详细信息，该服务器不存在，因此Django在尝试发送电子邮件时无法连接到该服务器。在开发过程中，使用

或者

问题来自我的域电子邮件托管提供商。谢谢

但是默认情况下，电子邮件后端是存在的。我以前用过它，我不知道它为什么会这样。当我输入虚拟后端时，它工作正常。我不明白为什么会这样。有什么想法吗？

EMAIL_BACKEND = 'django.core.mail.backends.dummy.EmailBackend'
