imapclient error on Windows

Question

Environment that I\'m having trouble on: Python 2.7.11 on Windows10 (patched up to date). Python installed via a msi. I\'ve checked PATH settings in settings, and it\'s set

Answer 1

This is not a final answer, but the work around that I've found is to uninstall imapclient and install an older version. Version 0.13 (and 0.11) worked for me, however after upgrading to 1.0.1 I got the same error message that you posted.

To uninstall imapclient with pip, run:

pip uninstall imapclient

To install the older 0.13 version with pip, run:

pip install imapclient==0.13

To verify the version of imapclient, from the interactive shell run:

>>> import imapclient >>> imapclient.__version__

Answer 2

Here's a workaround that worked for me (Python 3.5, Windows 10), and which doesn't require downgrading:

from backports import ssl
from imapclient import IMAPClient

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1_2)

server = IMAPClient('imap.gmail.com', ssl=True, ssl_context=context)

The above code was derived from the developer's workaround here, but I found I only needed the one line defining context to make it work. Specifying other SSL/TLS protocols also worked.
