在代理后面的 Django 中使用 send_mail 时出现错误

Question

我试图使用 gmail 从我的 Django 应用程序发送电子邮件。 我将这些电子邮件设置添加到settings.py

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'myemail@gmail.com'
EMAIL_HOST_PASSWORD = 'mypassword'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

但它会引发此名称解析错误：

Traceback (most recent call last):
File "/usr/lib/python3.4/code.py", line 90, in runcode
  exec(code, self.locals)
File "<console>", line 1, in <module>

  return mail.send()

  return self.get_connection(fail_silently).send_messages([self])

  self.connection = connection_class(self.host, self.port, **connection_params)
File "/usr/lib/python3.4/smtplib.py", line 242, in __init__
  (code, msg) = self.connect(host, port)
File "/usr/lib/python3.4/smtplib.py", line 321, in connect
  self.sock = self._get_socket(host, port, self.timeout)
File "/usr/lib/python3.4/smtplib.py", line 292, in _get_socket
  self.source_address)
File "/usr/lib/python3.4/socket.py", line 494, in create_connection
  for res in getaddrinfo(host, port, 0, SOCK_STREAM):
File "/usr/lib/python3.4/socket.py", line 533, in getaddrinfo
  for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -2] Name or service not known

注意：我在代理后面工作。

此外，我尝试通过套接字连接到 google.com：

import socket
socket.gethostbyname('www.google.com')

它抛出：

[Errno 11001] getaddrinfo failed

Answer 1

1. 在 gmail.com 中启用 pop3
2. 为 Django 应用程序创建特定密码 ( http://support.google.com/accounts/bin/answer.py?hl=en&answer=185833 )
