Assuming you're using 'mail', have you tried fiddling with the authentication options under 'server settings' (mail -- preferences -- account)?

that would be because the server does not support authentication ;)

Assuming you're using the OSX mail client, edit the account settings, click 'Options' under 'Outgoing mail server' and set 'authentication' to 'none'.
