Been working with my webhost, after installing Thunderbird and downloading 20k emails I couldnt login and despite changing password and updating, it wont login. I installed an icloud account too and that is working fine. I also added the new password to Mac Mail and that is logging in fine.

the error messages indicate that there is a glitch with the software not the server configuration


It is actually dropping the session before the password is rejected. 2015-12-31 22:11:00 doot_login authenticator failed for ([1]) [.249]:49342: 501 Authentication cancelled 2015-12-31 22:11:00 doot_login authenticator failed for ([]) [.249]:49343: 501 Authentication cancelled

Not an area I have great experience in. So I'll offer these two bits and if they do not help, then hopefully someone else can assist you.
