IMAP4_SSL: EOF occurred in violation of protocol

Question

I'm not great with Python but I've inherited a script (from a former co-worker) that is giving the above error. Here's the traceback:

  File "/abackup/rob/python/mail/one_and_one/__init__.py", line 119, in open
    mailbox = imaplib.IMAP4_SSL(self.host, self.port)
  File "/usr/local/lib/python2.6/imaplib.py", line 1137, in __init__
    IMAP4.__init__(self, host, port)
  File "/usr/local/lib/python2.6/imaplib.py", line 163, in __init__
    self.open(host, port)
  File "/usr/local/lib/python2.6/imaplib.py", line 1150, in open
    self.sslobj = ssl.wrap_socket(self.sock, self.keyfile, self.certfile)
  File "/usr/local/lib/python2.6/ssl.py", line 350, in wrap_socket
    suppress_ragged_eofs=suppress_ragged_eofs)
  File "/usr/local/lib/python2.6/ssl.py", line 118, in __init__
    self.do_handshake()
  File "/usr/local/lib/python2.6/ssl.py", line 293, in do_handshake
    self._sslobj.do_handshake()
ssl.SSLError: [Errno 8] _ssl.c:480: EOF occurred in violation of protocol

As far as I know, this was working a month ago. I have tried Googling and looked at the only other thread of stackoverflow that references this, but it doesn't seem to apply... the error seems to be occurring within the library, since all I'm calling is the constructor with a valid hostname and port.

看来这与我们的防火墙或某些东西有关...我当然无法控制...叹气...
