(JavaScript) Create MDN (Message Disposition Notification) Email
Demonstrates how to create a MDN (Message Disposition Notification) Email having the format as defined in RFC 3798. Note: This example requires Chilkat v11.0.0 or greater.
var success = false;
var email = new 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 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"
success = email.LoadEml("someEmail.eml");
if (success == false) {
console.log(email.LastErrorText);
return;
}
// 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:
var 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.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));
var xmlStr = xml.GetXml();
// 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.
var bHeaderOnly = true;
// 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).
var humanReadableExplanation = "Blah blah blah. Your message has been received and displayed. Blah blah blah";
// OK, we're ready to create MDN...
var mdnEmail = new CkEmail();
success = email.ToMdn(humanReadableExplanation,xmlStr,bHeaderOnly,mdnEmail);
if (success == false) {
console.log(email.LastErrorText);
return;
}
// Show the MIME of the source (original) email:
console.log(email.GetMime());
console.log("**************************************");
// Show the MIME of the MDN email:
console.log(mdnEmail.GetMime());
// Sample output showing the MIME of the original email,
// and the MDN email created based upon it:
