Create Email with Non-Standard Binary Body

Creates an email where the only body is a binary WAV file. The technique used in the example could be applied to other binary files, such as PDF, MS-WORD docs, Excel docs, etc. Delphi DLL

uses
    Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics,
    Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Email, Mime;
