    //  An MDN can be used to notify the
    //  sender of a message of any of several conditions that may occur after
    //  successful delivery, such as display of the message contents,
    //  printing of the message, deletion (without display) of the message,
    //  or the recipient's refusal to provide MDNs.
    //  (for more information, see RFC 3798)

    //  IMPORTANT:
    //  Note: Please be careful in sending automated MDN's.
    //  It is important to be aware of an issue called "backscatter".
    //  See the Wikipedia article here:  http://en.wikipedia.org/wiki/Backscatter_%28e-mail%29

    //  The CreateMdn method is called to create a new
    //  MDN email based upon the email object calling CreateMdn.
    //  The email object instance used to call CreateMdn would
    //  typically be an email received from a POP3 or IMAP server.
    //  In this case, to simplify the example, we'll load the email
    //  from a .eml file.

    //  This example will be creating a MDN for "someEmail.eml"
    success = email.LoadEml("someEmail.eml");
    if (success != true) {
        System.out.println(email.lastErrorText());
        return;
    }

    //  The MDN created by CreateMdn will contain a
    //  "message/disposition-notification" MIME sub-part that will
    //  be composed of a number of name-value pairs.
    //  See RFC 3798  ( http://tools.ietf.org/html/rfc3798 )
    //  The name-value content for this part is passed
    //  as XML to CreateMdn. This part of the example
    //  prepares the XML:
    CkXml xml = new CkXml();

    //  For this example, we're just adding a few name-value pairs.
    //  These should not be considered to be correct, required or
    //  even sensible -- they are simply for the example.
    xml.put_Tag("DispositionFields");
    xml.NewChild2("Disposition","manual-action/MDN-sent-manually; displayed");
    xml.NewChild2("Original-Message-ID",email.getHeaderField("Message-ID"));
    xml.NewChild2("Final-Recipient",email.getToAddr(0));

    String xmlStr;
    xmlStr = xml.getXml();

    //  The last argument to be passed to CreateMdn will be a boolean
    //  indicating whether to include the entire MIME of the calling
    //  email object in the MDN, or only the header.
    //  It may make sense to include the entire email for small emails,
    //  but for large emails (with large attachments) it's probably
    //  best to make the MDN header-only.
    boolean bHeaderOnly;
    bHeaderOnly = true;

    //  The first argument to be passed to CreateMdn will
    //  be a human-readable explanation that will be placed
    //  into the 1st MIME part of the MDN (see RFC 3798).
    String humanReadableExplanation;
    humanReadableExplanation = "Blah blah blah.  Your message has been received and displayed. Blah blah blah";

    //  OK, we're ready to create MDN...
    CkEmail mdnEmail;

    mdnEmail = email.CreateMdn(humanReadableExplanation,xmlStr,bHeaderOnly);

    if (!(mdnEmail == null )) {
        //  Show the MIME of the source (original) email:
        System.out.println(email.getMime());

        System.out.println("**************************************");

        //  Show the MIME of the MDN email:
        System.out.println(mdnEmail.getMime());
    }
    else {
        System.out.println(email.lastErrorText());
    }

    //  Sample output showing the MIME of the original email,
    //  and the MDN email created based upon it:
