use chilkat();

$email = new chilkat::CkEmail();

#  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 != 1) {
    print $email->lastErrorText() . "\r\n";
    exit;
}

#  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:
$xml = new chilkat::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));

$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.
$bHeaderOnly = 1;

#  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).
$humanReadableExplanation = "Blah blah blah.  Your message has been received and displayed. Blah blah blah";

#  OK, we're ready to create MDN...

# mdnEmail is a CkEmail
$mdnEmail = $email->CreateMdn($humanReadableExplanation,$xmlStr,$bHeaderOnly);

if (!($mdnEmail eq null )) {
    #  Show the MIME of the source (original) email:
    print $email->getMime() . "\r\n";

    print "**************************************" . "\r\n";

    #  Show the MIME of the MDN email:
    print $mdnEmail->getMime() . "\r\n";
}
else {
    print $email->lastErrorText() . "\r\n";
}

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