Build an EDIFACT Email Body

Demonstrates the Chilkat Email.SetEdifactBody method, a convenience that constructs the customary MIME headers and body for sending an EDIFACT message. It sets the body to the EDIFACT content, sets Content-Transfer-Encoding to Base64, sets Content-Type to application/EDIFACT (with a name attribute from the 2nd argument), and sets Content-Disposition to attachment (with a filename from the 3rd argument). The 4th argument is the charset the message is converted to before Base64 encoding. The subject, recipients, and FROM are left unchanged.

Background: EDIFACT is a long-standing international standard for Electronic Data Interchange (EDI) — structured business documents such as purchase orders (ORDERS) and invoices (INVOIC) exchanged between trading partners. Sending EDIFACT over email requires wrapping the payload in a specific set of MIME headers; SetEdifactBody handles that boilerplate so the message is formatted the way EDI systems expect.
