        folder.open(Folder.READ_WRITE);
        if (messages.length > 0){
            Message[] messages = folder.getMessages();
         
            MimeMessage thisMessage = (MimeMessage)messages[0];
            System.out.println(thisMessage.getContent());
         
            sendMessage("System event notification",thisMessage.getContent().toString());

        }        
        folder.close(true);
        store.close();
