Remove the HTML Body from an Email

Demonstrates the Chilkat Email.RemoveHtmlAlternative method, which removes the HTML body from the email if one exists. Other body representations, attachments, and related items remain unchanged. This example builds a message with both plain-text and HTML alternatives, then removes the HTML.

Background: A multipart/alternative message carries the same content as both HTML and plain text. Dropping the HTML alternative yields a leaner, text-only message — useful for reducing size, sidestepping HTML-rendering or spam concerns, or enforcing a plain-text policy. The plain-text alternative remains as the message body. Its counterpart is RemovePlainTextAlternative.
