I'm not suggesting that you debug the standard library because I think
the library itself is broken. I'm suggesting that using the source
code that's freely available to you can help you have some insight on
what's going wrong.
Do you have a working theory on what you're doing wrong? You've
already ruled out the port. Why are you changing the invocation
between versions of Python?
imaplib.IMAP4_SSL('xxxxx') # 2.6
imaplib.IMAP4('xxxxx', imaplib.IMAP4_SSL_PORT) # 3.2
I'm sure the standard library works fine, and you're just doing
something silly, like mistyping the host name or forgetting to start
the server. Maybe you're running 3.2 in a slightly different OS
environment?
The ONE thing that you can find out almost immediately is what
self.host and self.post are set to when _create_socket gets called.
You could almost immediately narrow down the problem to
socket.create_connection() instead of IMAP.
