Get Delivery-Status Info as JSON

See more Email Object Examples

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.
