Get Delivery-Status Info as JSON

Demonstrates the Chilkat Email.GetDsnInfo method, which — when IsMultipartReport indicates the email is a multipart/report — obtains the delivery-status information as a JsonObject. This example loads a bounce message, confirms it is a report, and prints the extracted DSN details as JSON.

Background: A bounce (DSN) carries its key facts — which recipient failed, the status code, the reporting server — in a machine-readable message/delivery-status part. Rather than parsing those raw fields yourself, GetDsnInfo gathers them into a structured JSON document you can query with the JsonObject API, making it easy to automate bounce handling and prune failed addresses from a mailing list.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

//  Demonstrates the GetDsnInfo method, which, for a multipart/report email, obtains the
//  delivery-status information as a JSON object.

var email = new CkEmail();

success = email.LoadEml("qa_data/eml/dsn_bounce.eml");
if (success == false) {
    console.log(email.LastErrorText);
    return true;
}

//  Only meaningful for a multipart/report email.
if (email.IsMultipartReport() == true) {
    var json = new CkJsonObject();
    success = email.GetDsnInfo(json);
    if (success == true) {
        console.log(json.Emit());
    }

}
else {
    console.log("This email is not a multipart/report.");
}
