Ralf,
I haven't changed the default HTML template, which is as follows:
To: {friend_email}
From: {firstname} {lastname} <{sender_email}>
Subject: Website recommendation by {firstname} {lastname}
Content-Type: text/html
Content-Transfer-Encoding: 8bit
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Website recommendation by {firstname} {lastname}</title>
<style type="text/css">
<!--
body {
font-family:Arial, Helvetica, sans-serif;
background-color:#A8DBEE;
color:#00007F;
}
-->
</style>
</head>
<body>
<p>{comment}</p>
<p><a href="{url}">{url}</a></p>
<p>{checkbox:newsletter}</p>
<p>{checkbox:information}</p>
<p>{radiobutton:salutation}</p>
<p>{select:Vote}</p>
<p>-----------------------------------------</p>
<p>This e-mail has been sent by {firstname} {lastname} ({sender_email}).</p>
<p>{env_user_agent}</p>
<p>{env_remote_address} ({env_remote_host})</p>
<p>{env_year}-{env_month}-{env_day} ({env_hour}:{env_minute}:{env_second})</p>
</body>
</html>
I'm trying this out on some test web space at the moment at

Thanks for any help you can offer,
