       System.out.println("Sucessfully Sent mail to All Users");
   }

   public void sendSSLMessage(String recipients[], String subject,
           String message, String from) throws MessagingException {
       boolean debug = true;

       Properties props = new Properties();
       props.put("mail.smtp.host", SMTP_HOST_NAME);
       props.put("mail.smtp.auth", "true");

       InternetAddress addressFrom = new InternetAddress(from);
       msg.setFrom(addressFrom);

       InternetAddress[] addressTo = new InternetAddress[recipients.length];
       for (int i = 0; i < recipients.length; i++) {
           addressTo[i] = new InternetAddress(recipients[i]);
       }
       msg.setRecipients(Message.RecipientType.TO, addressTo);

       // Setting the Subject and Content Type
       msg.setSubject(subject);
       msg.setContent(message, "text/plain");
       Transport.send(msg);
   }
}
