In plain text I use name @t domain d0t com
while on my blog and websites I use a simple js script:
<SCRIPT TYPE="text/javascript">

emailE='domain.com' emailE=('name' + '@' + emailE) document.write('or <A href="mailto:' + emailE + '">email me</a>.')
//--> </script>
<NOSCRIPT> <em>Email address protected by JavaScript.<BR> Please enable JavaScript to contact me.</em> </NOSCRIPT>
