I had an old outgoing email server that I haven't used for some time. After my account there was disabled TB started to ask the password for that outgoing email server at every startup. To fix this I wen't to the outgoing email server settings and deleted that particular server, but this did not help and TB keeps asking for the password for that server at every startup.

Is it possible that TB hasn't updated the settings correctly? I even tried to recreate the server and make it not ask for password, but that didn't help either.
