Question

我正在使用gevent在gunicorn 0.12.2上运行django应用程序并安装在virtualenv环境中。当我尝试连接到smtp.gmail.com（django-registration创建帐户视图）时，我收到以下错误：

Answer 1

端口是一个字符串。当它被传递给_socket.getservbyname（）时会导致一个难以理解的错误，它需要一个像'smtp'这样的字符串。

Answer 2

我在settings.py中尝试使用EMAIL_PORT中的环境变量时遇到了同样的问题。环境变量默认返回一个字符串，但该端口必须是整数。我改变了我的设置：

EMAIL_PORT = os.environ.get('MAILGUN_SMTP_PORT', 25)

为：

EMAIL_PORT = int(os.environ.get('MAILGUN_SMTP_PORT', 25))

Answer 3

你能试试gevent-1.0a2吗？它有一个完全不同的DNS实现。

使用gevent socket.py时无法使用Django连接到smtp服务器
