The problem as you saw with your test is not the server, your server is working properly the only reason you cannot authenticate and send mail is because the windows mail client you are using is brain dead, if you want to continue using windows mail then talk to Microsoft to help you fix the client, our use something else.
But your server is fine as you can see that when you connect to it via telnet you can authenticate.
The problem is the client NOT the server.
