Pascal (Lazarus/Delphi)

Set a MIME Body from HTML

Demonstrates the Chilkat Mime.SetBodyFromHtml method, which sets the body as HTML and changes the media type to text/html. The only argument is the HTML text.

Background: Setting an HTML body is how you produce the rich-formatted part of a message. Chilkat marks it text/html and chooses the encoding based on the content — 7bit for ASCII, a charset-aware encoding otherwise. In practice an HTML email is usually paired with a plain-text alternative inside a multipart/alternative so clients that cannot render HTML still have readable text.
