Set the Email Body from a BinData

Demonstrates the Chilkat Email.SetBodyBd method, which sets the main email body from the binary data in a BinData object. The second argument is the MIME Content-Type, the third is the disposition (may be empty, inline, or attachment), and the fourth is the filename. This example loads HTML content into a BinData and sets it as the body.

Background: SetBodyBd gives low-level control over the body when you already have its bytes and want to specify the exact Content-Type and MIME disposition yourself. It suits content that is generated or stored as binary — for example an EDI payload, a pre-rendered HTML fragment, or any custom content type — where the convenience of SetHtmlBody / SetTextBody does not apply.
