[ubuntu] Thunderbird keeps saying my password is incorrect

I thought I would try Thunderbird. It seems to have a problem with my email password. It just keeps asking for the password, I enter it correctly, but it can't log in. I tried various settings but then Thunderbird tells me 'this setting is not correct for this server' or something like that, so I go back to 'normal password'.

My name, as seen in my email is Pedroski. I don't know if that is important, but when I was setting up the Thunderbird account, it also told me the name was wrong.

Please see the attached thumbnail for a peek at the problem.
