Checking mail ONLY when theres new mail

Question

Hello! :)
I have a program that checks for new mail, parses data in the new mail, sleeps for one minute, and then repeats this whole process infinately. I think it'd be more effective if I only check mail when there's NEW mail, not every minute....
How do I do this?
Many Thanks!
Liam

Hi... just one last question... I tried using MessageCountListener but it somehow DOESN'T recognize when there's new mail (the messagesAdded method isn't called). I think I might have added the MessageCountListener wrong, but I can't figure out why.
Also, I still use a "while" loop, just so that my program won't end, and this is eating up memory! :(
Anyway, this is some of my code...
public class MAPI implements MessageCountListener
     // some variable declarations
     MAPI() throws Exception
      Properties props = new Properties();                         
      Session session = Session.getInstance(props, null);               
      Store store = session.getStore("imap");                      
      store.connect(host, username, password);
      Folder folder = store.getFolder("INBOX");
      folder.open(Folder.READ_WRITE);
      folder.addMessageCountListener(this);
      while(true)
    public static void main (String args[])  throws Exception
       new MAPI();
    public void messagesAdded(MessageCountEvent e)
       System.out.println("You've got mail!");
    public void messagesRemoved(MessageCountEvent e) {}
}
