Django 发送电子邮件错误：ConnectionRefusedError：[Errno 61] 连接被拒绝

如何解决Django 发送电子邮件错误：ConnectionRefusedError：[Errno 61] 连接被拒绝

当我遇到此错误时，我正尝试使用 send_mail() 中的 django.core.mail 函数通过 Django 发送电子邮件：

ConnectionRefusedError: [Errno 61] Connection refused

这是我的代码，直接来自文档：

from django.core.mail import send_mail

send_mail(
    'Subject here','Here is the message.','from@example.com',['to@example.com'],fail_silently=False,)

我将 from@example.com 替换为电子邮件 ID 之一，并将 to@example.com 替换为我的其他电子邮件 ID 之一。

当我运行 runserver 时，我收到这个奇怪的错误

$ python3 manage.py runserver

我正在使用 Django 3.2 和 Python 3.9.2。我真的很感激一些帮助。
