Steps to reproduce the error

  • Just run offlineimap

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 posting it here because I wonder if the issue is applicable to offlineimap3 as well. If it does, it will be great if we could fix it.

Hello @xianwenchen

your Python version is 2.7. Offlineimap3 needs Python 3:

system/distribution (with version): Void
offlineimap version (offlineimap -V): offlineimap v7.3.3, imaplib2 v2.101 (bundled), Python v2.7.18, OpenSSL 1.1.1k 25 Mar 2021
**Python version: 2.7**
server name or domain: imap.163.com
CLI options: none

Cheers,

As expected, the problem exists in offlineimap3 now. I have confirmed it using the master from the git repository. Could you reopen the issue?
