Get SMTP reply code

Question

Hi,
I am using destination mail server to send emails. For example to send an email to [email protected] , I do an MX lookup on mailservers for hotmail.com and use that to send mail to user fred. The reason for this is that
I get better email validation. For example - if user fred does not exist then, I know it straight away as I get error 550.
From what I can see, Javamail does not provide functionality to retreive SMTP reply code. It will be good if a method is added to Messaging Exception class that returns the SMTP reply code that caused the exception.
From what I understand, the only method to get SMTP reply code is to parse the exception message for an int.
Is there any alternative to get the SMTP reply code that caused the exception?
Regards,
Anmol

     public static int getSmtpErrorCode (Exception ex){
          String exceptionString = ex.toString();
          StringTokenizer tokens = new StringTokenizer(exceptionString);
          int code = 0;
          boolean flag = false;
          while(tokens.hasMoreTokens()){
               if (flag == true) {
                    break;
               try {
                    flag = true;
                    code = Integer.parseInt(tokens.nextToken());
               } catch (Exception e){
                    flag = false;
          return code;
     }
