Hi,

I need to read email messages that are already in the inbox to check for a particular message as well as listen to new messages arriving (the confirmation email I send may have already arrived before the user launches or even installs my app). I know how to set up a listener for new messages from reading the forums ( Mail Listener ), but I can't figure out how to search through existing messages.

I want to do something along the lines of:- 

      try
        {
            Store store = Session.getDefaultInstance().getStore();
            net.rim.blackberry.api.mail.Message [] msgs = store.getMessages();
            for(int i=0; i < msgs.length; i++)
            {
                if (msgs[i].isInbound())
                {
                    String subject = msgs[i].getSubject();
           
                    if ((subject != null) && (subject.equals("My subject")))
                    {
                      //do stuff
                    }
                }
            }
        }

But store.getMessages() isnt valid on a store and I cant see any other api call I can use to get at the messages that are already in the store.

Please have a look at the FolderListScreen found in the complete example you can download using the link below.  Please note that the full example requires BlackBerry JDE version 4.5.0+.

Here is some sample code of how to iterate through existing messages.  It uses a couple of our library classes but it shouldn't be much work to refactor those out.  Some things to note are that:

1. It uses service books to get all email accounts.
2. It checks the sub-folders because some BES accounts have sub folders in their inbox
3. You can check your message where the comment says: Check the message here

        Iterator iterator = uniqueStores.iterator();
        while (iterator.hasNext()) {

            Store store = (Store) iterator.next();
            Folder[] folders = store.list();
            for (int i = 0; i < folders.length; i++) {
                Folder folder = folders[i];

                checkFolder( folder );
            }

    private Set getUniqueStores() {

        Set uniqueStores = new HashSet();
