am using the below code.
Properties props = System.getProperties();
//          Setup mail server
          props.put("mail.smtp.host", smtpHost);
          props.put("mail.smtp.port","25");
          props.put("mail.smtp.auth", isAuth);
     Authenticator auth = new UserAuthenticator();
//          Get session
          Session s = Session.getDefaultInstance(props,auth);
//          Define message
          Message m = new MimeMessage(s);
//          setting message attributes
          try {
               m.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
               InternetAddress f_addr=new InternetAddress(from);
               f_addr.setPersonal(personalName);
               m.setFrom(f_addr);               
               m.setSubject(subject);
               m.setSentDate(new Date());
               m.setContent(msg,"text/plain");
               m.saveChanges();
//               send message
               Transport.send(m);
