Running offlineimap with tunneled connections fails.
The connection to the server is right, the server sends the
PREAUTH message, offlineimap reads it and provides a reply, something
like 'UID1 CAPABILITY'. This message is added to the output queue in
imaplib2.py, function _command():
if literal is None:
self.ouq.put(rqb)
return rqb
Then, the function _writer() in imaplib2 calls the self.send() function:
try:
self.send(rqb.data)
if __debug__: self._log(4, '> %r' % rqb.data)
self object is an IMAP4_Tunnel class, and the function send() writes the
message, but the message is not sent to the server.
We need flush the buffer.
