    // Connect to an IMAP server.
    // Use TLS

    // Once the mailbox is selected, the NumMessages property
    // will contain the number of messages in the mailbox.

    // fetch each message by sequence number.

        // ... your application may process each MIME string...

    // An alternative is to download each email in the form of an
    // email object, like this:
    CkEmail *email = 0;
    for (i = 1; i <= n; i++) {

        // Download the email by sequence number.
        email = imap.FetchSingle(i,bUid);

        // ... your application may process the email object...

        delete email;
    }

    // Disconnect from the IMAP server.
    success = imap.Disconnect();
