I can't add an existing email on Thunderbird (email address from China).

Sijian He

Whenever I add the mail, it said "Configuration found in Mozilla ISP database", but then has this prompt "Unable to log in at server. Probably wrong configuration, username or password." However, I am pretty sure my email address and password are correct, and the configuration is correct. My email ends with "@163.com".

And it turns out that my Gmail account cannot be added too, so it is not because the email address is from China.

it may be because netease changed their way of granting IMAP right. Google is about OAuth I guess?
