I hope you don't mind, but I changed the code a little to make it some neater; <style> tags outside the <header> isn't too nice imho
HTML Code:
<table width="90%" cellspacing="1" cellpadding="3" border="0" align="center">
<tr>
<td><span class="smallfont"><strong>Administrator's Warning:</strong></span></td>
</tr>
<tr>
<td style="font-family: Verdana, Arial, Courier, Courier New; color: #465584; background-color: #FAFCFE; border: 1px dotted #000; padding: 2px; width:98%; margin: 0px auto 0px auto; overflow: auto; color: red; font-weight: bold"><img align="left" src="../images/mod.gif">{param}</td>
<tr>
</table>
