Actually you can. You need to write this in your email :<div><br class="webkit-block-placeholder"></div><div><span class="Apple-style-span" style="font-family: &#39;Lucida Grande&#39;; font-size: 11px; white-space: pre-wrap; ">#set ($youremail = &quot;Subject: Your Subject Here ${<a href="http://xwiki.nl">xwiki.nl</a>} Your Email Content&quot;)</span></div>

<div></div>Hi,
<div><span class="e" id="q_117efe04290bd0c3_5"><div><br>&nbsp;</div>
<div>I think the plugin hasn&#39;t been activated on the farm for fear of people 
using it to send spam messages... I talked to our admin about it but he thinks 
it wouldn&#39;t be safe to do otherwise.</div>
<div><br>&nbsp;</div>
<div>Sorry about that...</div>

  <div></div>Hi Brandon, 
  <div><br>&nbsp;</div>
  <div>This method has been deprecated in favor of using the Mail Sender Plugin 
  (&nbsp;<a href="http://code.xwiki.org/xwiki/bin/view/Plugins/MailSenderPlugin" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://code.xwiki.org/xwiki/bin/view/Plugins/MailSenderPlugin</a>&nbsp;).</div>

  <div><br>&nbsp;</div>
  <div>The plugin offers 4 different methods, some of them allows you to set the 
  subject of your email.</div>
  <div><br>&nbsp;</div>
  <div>Check the example described at the end of the page for a live 
  example.</div>
