<p>SpamSpan doesn't manage existing links such as <a href="mailto:user@example.com">Name Surname</a>.<br>
So, I modified these two function in spamspan.module:</p>
<div class="codeblock">
<pre><span style="color: #000000"><span style="color: #0000BB"><?php<br></span><span style="color: #007700">function </span><span style="color: #0000BB">spamspan_callback</span><span style="color:

<p>Since I use the spamspan filter after URL filter, simple email address (as user@<b></b>example.com) are already converted into links (as <a href="mailto:user@example.com">user@example.com</a>) when spamfilter come in action. This way, the pattern I can use is much more simple ;-)</p>
