Check Whether an Email Is a multipart/report

Demonstrates the Chilkat Email.IsMultipartReport method, which returns true when the top-level message structure is a multipart/report (such as a bounce/DSN or a read receipt/MDN). This example loads an email and reports whether it is a multipart/report.

Background: Automated mail — delivery failures and read receipts — arrives wrapped in the multipart/report structure, which carries machine-readable report parts. Detecting it with IsMultipartReport is the first step in a bounce-handling pipeline: once you know a message is a report, you can pull its parts with GetReport or read delivery fields with GetDeliveryStatusInfo to act on failures automatically.
