how to check that the email id exist in domain without sending any mails using java

Question

Is there any way to verify where the email id exist in domain or not?

I am having the following function: it checks only for valid domain, but i need to check for valid email address in domain without sending any mails.

 public boolean isValidEmailAddress(String email) {
   boolean result = true;

   try {
      InternetAddress emailAddr = new InternetAddress(email);
      emailAddr.validate();

   } catch (AddressException ex) {
      result = false;
   }
   return result;
}
