Hi all,

in my case there is a service that schould open a connection to a imap server and schould fetch a message as soon as the were received. For that i

run startIdle within a background worker and try to stop when the newmessagereceive event is published and fetch the new message after that.

But a exception is thrown afterBeginHeaderObject is called (message -> Command "DONE" failed : * 20 EXISTS), so what´s the wright ay to use IDLE?

Thanks in advance

Ralf

private void startImap()
{
            idleWorker = new BackgroundWorker();
            idleWorker.DoWork += new  DoWorkEventHandler(StartIdleProcess);
            idleWorker.RunWorkerAsync();

            Console.ReadLine();

            idleWorker.CancelAsync();
}

        private static void StartIdleProcess(object sender, DoWorkEventArgs e)
        {
            // Get the BackgroundWorker that raised this event.
            //BackgroundWorker worker = sender as BackgroundWorker;

            if (imapClient != null && imapClient.IsConnected)
            {
                imapClient.StopIdle();
                imapClient.Disconnect();
            }

            imapClient = new Imap4Client();
HeaderRetrievingEventHandler(imapClient_HeaderRetrieving);
            imapClient.HeaderRetrieved += new HeaderRetrievedEventHandler(imapClient_HeaderRetrieved);       
            imapClient.Nooped += new NoopedEventHandler(imapClient_Nooped);            
            imapClient.NewMessageReceived += new NewMessageReceivedEventHandler(imapClient_NewMessageReceived);
            
            imapClient.Connect("my.server.com");
            imapClient.LoginFast("user", "password");            
            box = imapClient.SelectMailbox(@"Folder");            
            imapClient.StartIdle();
        }

        static void imapClient_NewMessageReceived(object sender, NewMessageReceivedEventArgs e)
        {
            imapClient.StopIdle();

            Console.WriteLine(string.Format("{0} new message(s) were received!", e.MessageCount));            
            
            box.Fetch.BeginHeaderObject(box.FirstUnseen, null);
        }
