hi
the properties that you pass to the

 
Session session = Session.getDefaultInstance(props, null);
// Define message
MimeMessage message = new MimeMessage(session);
// set from and to adresses, subject, body....
// .....    
// Send message
Transport tr = session.getTransport("smtp");
// connect and authenticate
tr.connect(host, port, user, pwd);
// apply changes, to make authentication work
message.saveChanges();
// send the message, USE THIS method. the other 
// does not work properly
tr.sendMessage(message,message.getAllRecipients());
// close the transport
tr.close();

the props must contain:

props.put("mail.smtp.auth","true");

along with the other stuff you need there.
hope this helped.
