Is it simply the wrong port?  (IMAP4_SSL_PORT vs. IMAP4_PORT)

How long do you wait before seeing the timeout?

Have you tried print-debugging within your local copy of imaplib.py?
The code related to making the connection just wraps
socket.create_connection:


   234
   235     def _create_socket(self):
   236         return socket.create_connection((self.host, self.port))
   237
   238     def open(self, host = '', port = IMAP4_PORT):
   239         """Setup connection to remote server on "host:port"
   240             (default: localhost:standard IMAP4 port).
   241         This connection will be used by the routines:
   242             read, readline, send, shutdown.
   243         """
   244         self.host = host
   245         self.port = port
   246         self.sock = self._create_socket()
   247         self.file = self.sock.makefile('rb')
