multipart/alternative support in e-mail

Вопрос

We would like to include multipart/alternative (plain-text) support in a HTML email template. I've searched Google for concrete examples, but couldn't find it. It's a classic ASP website with a custom newsletter module. I know that modern newsletter services already support such feature.

The reason I'm asking this, is because there are no clear directions given when searching on Google. Also a lot websites are referring to newsletter services.

The template:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <meta http-equiv="Content-Style-Type" content="text/css">
    <title></title>

<style type="text/css">
    /* setting font style for Outlook 2007 */
    body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,p,pre,blockquote,th,td,span,em {
        color: #ffffff;
        font-family: 'Trebuchet MS', sans-serif;
        font-size: 15px;
        line-height: 1.333em;
    }
    body {
        margin: 0;
        padding: 0;
    }
    p {
        margin: 0 0 1.3em 0;
    }
</style>
