Id start trouble shooting there. Logs indicate you only have one user and that one user doesn't have a password where its been told to look. Maybe a typo in username? Maybe you have just the user part and its looking for a match of user@domain for authorization, or the other way around. Since there are many ways you can setup postfix to work, its hard to guess what the issue is without seeing how everything is setup.
