Render an Email to MIME in a StringBuilder

Demonstrates the Chilkat MailMan.RenderToMimeSb method, which renders an Email object as MIME text and appends the result to a StringBuilder, without sending the email. This example renders a message into a StringBuilder and prints it.

Background: This is the StringBuilder version of RenderToMime. Appending into a StringBuilder is more efficient when the MIME is large or when you plan to further inspect or manipulate it — searching, replacing, or accumulating additional text — without creating extra intermediate string copies.
