I asked - is it manually entered address or generated-shown automatically?!
If you can use HTML in this area, where e0mail placed you can
1/ Find (somewhere here on site) easy smarty-plugin "Email Obscurator", which will modify all e-mail addresses on site,
2/ Insert endoded manually full e-mail (can be decoded by smart-spiders)
Example (can't write full, because Newbb renders HTML-coded chars even inside code tag)
<a href="&#...;&#...;&#...;</a>
3/ Use embedded Java-script instead of HTML-codes
<script language="JavaScript"> <!--
document.write ('....')
// -->
</script>
Ask Google about "E-mail cloaker"
