Add the following code where you would like the email address to appear, replacing the example reversed address:
var s = 'moc*elpmaxe~em';
var e = s.replace( '~', '@' ).replace( '*', '.' ).split( '' ).reverse().join( '' );
$( '#liame' ).after( '<a>' ).next().attr( 'href', 'mail' + 'to:' + e ).text( e );
Optional: For ultra security, add some randomness (useless code) in case spammers catch wind of this specific code. Change the special characters, change the script ID from "liame", add some gibberish variables, etc.
If you are not using jQuery, here is a resource: youmightnotneedjquery.com. The logic can be quite quickly ported. If you are using a server-side language, you could go all out and really randomize your implementation.
