Steps to reproduce the error

Solution to the error

The IMAP server at imap.163.com implemented the IMAP ID extension. To successfully authenticate, the IMAP client must send client ID.

Here is a code snippet that I obtained from https://blog.yrpang.com/posts/45207/: 

from imapclient import IMAPClient

server = IMAPClient("imap.163.com", ssl=True, port=993)
server.login("<user>", "<passwd>")

server.id_({"name": "IMAPClient", "version": "2.1.0"})

messages = server.select_folder('INBOX')

I guess this may mean that we need a configuration option that is a switch. When the switch is on, offlineimap sends IMAP client ID.

I'm going to open a similar issue on offlineimap3.

You're correct I guess.

Due to the python2 end-of-life, we won't implement new features here. offlineimap3 is the correct project to make this request.
