Create a Message Disposition Notification (MDN)

See more Email Object Examples

Demonstrates the Chilkat Email.ToMdn method, which creates a new MDN (Message Disposition Notification) email in the format specified by RFC 3798, based on this email. The generated MDN is returned in the last argument, and the source email is not modified. The first argument is the human-readable message, the second is the disposition fields, and the third indicates whether to include headers only. This example builds an MDN for a received message.

// Important: Don't forget to include the call to System.loadLibrary
