    --  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 ToMdn method is called to create a new
    --  MDN email based upon the email object calling ToMdn.
    --  The email object instance used to call ToMdn 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"
    EXEC sp_OAMethod @email, 'LoadEml', @success OUT, 'someEmail.eml'
    IF @success = 0
      BEGIN
        EXEC sp_OAGetProperty @email, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        EXEC @hr = sp_OADestroy @email
        RETURN
      END

    --  The MDN created by ToMdn 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 ToMdn. This part of the example
    --  prepares the XML:
    DECLARE @xml int
    EXEC @hr = sp_OACreate 'Chilkat.Xml', @xml OUT

    --  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.  
    EXEC sp_OASetProperty @xml, 'Tag', 'DispositionFields'
    EXEC sp_OAMethod @xml, 'NewChild2', NULL, 'Disposition', 'manual-action/MDN-sent-manually; displayed'
    EXEC sp_OAMethod @email, 'GetHeaderField', @sTmp0 OUT, 'Message-ID'
    EXEC sp_OAMethod @xml, 'NewChild2', NULL, 'Original-Message-ID', @sTmp0
    EXEC sp_OAMethod @email, 'GetToAddr', @sTmp0 OUT, 0
    EXEC sp_OAMethod @xml, 'NewChild2', NULL, 'Final-Recipient', @sTmp0

    DECLARE @xmlStr nvarchar(4000)
    EXEC sp_OAMethod @xml, 'GetXml', @xmlStr OUT

    --  The last argument to be passed to ToMdn 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.
    DECLARE @bHeaderOnly int
    SELECT @bHeaderOnly = 1

    --  The first argument to be passed to ToMdn will
    --  be a human-readable explanation that will be placed
    --  into the 1st MIME part of the MDN (see RFC 3798).
    DECLARE @humanReadableExplanation nvarchar(4000)
    SELECT @humanReadableExplanation = 'Blah blah blah.  Your message has been received and displayed. Blah blah blah'

    --  OK, we're ready to create MDN...
    DECLARE @mdnEmail int
    EXEC @hr = sp_OACreate 'Chilkat.Email', @mdnEmail OUT

    EXEC sp_OAMethod @email, 'ToMdn', @success OUT, @humanReadableExplanation, @xmlStr, @bHeaderOnly, @mdnEmail
    IF @success = 0
      BEGIN
