Hello
so. as first step download attachment file "class_mailhandler.php" and put it inside inc folder (i've used 1.8.3 one for edits).

Then:
In global templates, make "html_mail" template and stylize it as you want to do. I'll provide here my code:
Code:
<body style="background: #F0F0F0;color: #333;text-align: left;line-height: 1.4;font-family: Segoe UI, Tahoma, Verdana, Arial, Sans-Serif;font-size: 13px;padding: 0;margin: 0;">
<div style="width: 100%;z-index: 9000;background-color: black;color: white;height: 60px;">
<div style="">
<ul style="float: left;list-style: none;margin: 0;padding: 0;">
<li style="float: left;position: relative;height: 50px;margin-top: -5px !important;">
<a href="http://forum.vnetwork.pl/portal.php" style="text-shadow: 0px 1px 1px rgba(0,0,0,0.5);display: block;color: #FFF;font-weight: normal;font-size: 0.93em;height: 100%;text-decoration: none;">
<img src="http://vnetwork.pl//logo_white.png" style="width: 150px;height: 60px;margin-top: -4px;" original-title="">
</a>
</li>
</ul>
</div>
</div>
<div style="text-align: left;line-height: 1.4;min-width: 990px;box-shadow: 0 5px 9px rgba(0,0,0,0.1);color: #333;font-family: Tahoma, Verdana, Arial, Sans-Serif;font-size: 13px;width: 90%;margin: auto auto;">
<div style="background: #fff;width: auto !important;padding: 20px;border-left: 1px solid #E0E0E0;border-right: 1px solid #E0E0E0;">
{$message}
</div>
</div>
<div style="clear: both;background: black;">
<div style="padding: 6px;font-size: 12px;margin: auto auto;color: white;">
