使用Python脚本发送包含Gmail的电子邮件

Question

我试图从python脚本发送电子邮件，但是我得到了这个错误。我使用的是虚拟服务器，现在我无法控制网络。

^CTraceback (most recent call last):
  File "sendemail.py", line 10, in <module>
    server = smtplib.SMTP('smtp.gmail.com:587')
  File "/usr/lib/python2.7/smtplib.py", line 256, in __init__
    (code, msg) = self.connect(host, port)
  File "/usr/lib/python2.7/smtplib.py", line 316, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "/usr/lib/python2.7/smtplib.py", line 291, in _get_socket
    return socket.create_connection((host, port), timeout)
  File "/usr/lib/python2.7/socket.py", line 566, in create_connection
    sock.connect(sa)
  File "/usr/lib/python2.7/socket.py", line 228, in meth
    return getattr(self._sock,name)(*args)

有问题的剧本是：

import smtplib
fromaddr = 'xpto@xpto.com'
toaddrs  = 'xxx@xxx.com'

msg = 'my message'

username = 'xpto@xpto.com'
password = 'password'

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
