Where are the Bounced Back Emails?

Question

Pardon the cross-posting, since I didn't get any responses in the JavaMial Forum.
====================================
Hi Java Gurus:
My application sends emails using JavaMail API. I am not receiving any bounced back emails though. What do I have to do to get them? Here's my code:
     // Builds and mails the message
     public boolean mailEm()
          // Get system properties
          Properties props = System.getProperties();
          // Setup mail server
          props.put("mail.smtp.host", smtpHost);
          props.put("mail.smtp.auth", "true");
          // Get session
          Session session = Session.getInstance(props,
                     new MyAthenticator(System.getProperty("user.name"), ""));
          session.setDebug(true);
          // Define message
          MimeMessage message = new MimeMessage(session);
          // Build mail message and send
          try
               // Create an internet address for sender
               InternetAddress addrFROM=new InternetAddress(System.getProperty("user.name"));
               // Build recipients list
               int numRecipients = addresses.size();
               InternetAddress[] address = new InternetAddress[numRecipients];
               for (int ii = 0; ii < addresses.size(); ii++)
                    address[ii] = new InternetAddress((String)(addresses.get(ii)));
               // Set message recipients
              message.setRecipients(Message.RecipientType.TO, address);
               // Set message sender
               message.setFrom(addrFROM);
         Address[] addresses = new Address[1];
         addresses[0] = (Address) addrFROM;
         message.setReplyTo(addresses);
               // Cycle for each file in the list
               for (int ii = 0; ii < filesToMail.size(); ii++)
                    message.setSubject(subject + " (Email " + (ii+1) +
                                                  " of " + (filesToMail.size()) + ")");
                   // create and fill the first message part
                   MimeBodyPart mbp1 = new MimeBodyPart();
                   mbp1.setText(messageText);
                   // create the second message part
                   MimeBodyPart mbp2 = new MimeBodyPart();
                   // attach the file to the message
                  FileDataSource fds = new FileDataSource((File) filesToMail.get(ii));
                   mbp2.setDataHandler(new DataHandler(fds));
                   mbp2.setFileName(fds.getName());
                   // create the Multipart message and its parts to it
                   Multipart mp = new MimeMultipart();
                   mp.addBodyPart(mbp1);
                   mp.addBodyPart(mbp2);
                   // add the Multipart to the message
                   message.setContent(mp);
                   // set the Date: header
                   message.setSentDate(new Date());
                   // send the message
                    Transport transport = session.getTransport("smtp");
                    transport.connect(smtpHost, System.getProperty("user.name"), "");
                    transport.send(message);
          catch( Exception ex)
               System.out.println(ex);
               ex.printStackTrace();
         return false;
      return true;
     }

exactely.. use the socket to connect to the SMTP server and send your message that way. Throw the API away. You can request for error e-mail and receipts and stuff when sending the "MAIL FROM:<email>" tihng.
