I amended your code and got it to work:

        Session session = Session.getInstance(props, auth);
        session.setDebug(true);
        OutputStream fos = null;
        try {
            fos = new FileOutputStream("classpathx-mail.out");
            PrintStream ps = new PrintStream(fos);
            session.setDebugOut(ps);
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            Message msg = new MimeMessage(session);
            msg.setFrom(new InternetAddress(senderAddress));
            msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(
                    recipientsAddress, false));
            msg.setSubject(subject);
            msg.setText(text);
            msg.saveChanges();
            Transport.send(msg);
        } catch (Exception e) {
            e.printStackTrace();
        }
        //fos.close();

Note that if you close the FileOutputStream at the end you won't get any 
output. This is down to some weirdness in exactly why/how/when PrintStreams get 
flushed, which I'm afraid I don't understand myself, but it's not a problem in 
the logging as far as I can see (which as I said simply uses the 
java.util.logging mechanism. If you find any way to shed any light on what's 
happening there please share it.
