use chilkat();

$email = chilkat::CkEmail->new();

# 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 = chilkat::CkXml->new();

# 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 Email
$mdnEmail = $email->CreateMdn($humanReadableExplanation,$xmlStr,$bHeaderOnly);
if ($email->get_LastMethodSuccess() == 0) {
    print $email->lastErrorText() . "\r\n";
    exit;
}

# 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";

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