Get the Complete MIME Header of an Email

Demonstrates the read-only Chilkat Email.Header property, which returns the complete MIME header generated from the current in-memory email object. Because this property is read-only, you modify individual fields through their corresponding properties or header methods rather than assigning to Header directly. This example sets a subject, from, and recipient, then prints the full MIME header.

Background: A MIME email is made of two parts separated by a single blank line: the header and the body. The header is a list of Field-Name: value lines — familiar ones include From, To, Subject, and Date, plus structural fields like Content-Type and MIME-Version. Reading the raw header is useful for debugging exactly what a message will look like on the wire.
