530 Authentication failed.

The log suggests that your password is wrong (try manually re-entering it and/or copy/pasting it if you have it saved somewhere else... or even have it changed).

However, this could also be caused by a server requiring an identd response that your not sending.

If you have access to change the password yourself, try that (try something simple as its also possible that the server does not support unusual characters in passwords such as spaces and uncommon punctuation)
