(Delphi ActiveX) Create MIME Containing Plain-Text

Calls SetBodyFromPlainText to load plain-text into the MIME body. Also sets the Content-Type header to "text/plain", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the text.

// Description: this is a test
// MyId: 123
// Content-Type: text/plain; 
// Content-Transfer-Encoding: 7bit

// This is the plain-text body

// Note: The Content-Transfer-Encoding may be changed.
// For example, to use "base64", do this:
mime.Encoding := 'base64';

// Show the MIME again, this time using the base64 
// transfer encoding:
Memo1.Lines.Add(mime.GetMime());

// Description: this is a test
// MyId: 123
// Content-Type: text/plain
