Render an Email to MIME Bytes in a BinData

Demonstrates the Chilkat MailMan.RenderToMimeBd method, which renders an Email object as MIME bytes and appends the result to a BinData, without sending the email. This example renders a message into a BinData and prints the byte count.

Background: This is the binary version of RenderToMime. A BinData holds raw bytes, which is the right container when you want the rendered MIME as binary — to write it directly to a file or socket, hash it, or hand it to another API expecting a byte buffer — rather than as text.
