Get a Report Part from a multipart/report Email

Demonstrates the Chilkat Email.GetReport method, which returns the body content of the Nth report within a multipart/report email. The NumReports property gives the count, and indexes are zero-based. This example loads a report email and prints each report part.

Background: A multipart/report message — used for bounces (DSNs) and read receipts (MDNs) — bundles machine-readable report parts alongside the human-readable explanation. GetReport returns the raw content of one such part so a program can parse it, for example to extract the failing recipient and status code from a bounce. Use GetDeliveryStatusInfo for direct field-level access to the delivery-status part.

'  A report returned by GetReport is the body of a report part -- for a bounce (DSN),
'  that is the machine-readable message/delivery-status part.  It looks similar to:
'  
'    Reporting-MTA: dns; mail.example.com
'    Received-From-MTA: dns; sender.example.com
