JavaMail 1.4.3 added support for NTLM authentication. Normally I would expect that the
same username and password would work with any authentication mechanism that's
supported by the server, but that doesn't seem to be the case here.
You can disable ntlm authentication by setting the session property "mail.imap.auth.ntlm.disable" to "true".
