Very nice! Assuming the client has JavaScript enabled, of course.
I took the liberty of adapting your code for use in a mailto link:

<a href="" onmouseover="this.href='moc.elpmaxe@enoemos:otliam'.split('').reverse().join(''); this.removeAttribute('onmouseover');">
<span style="display:inline-block; unicode-bidi:bidi-override; direction:rtl;" onmouseover="this.innerText=this.innerText.split('').reverse().join('');'';''; this.removeAttribute('onmouseover');">moc.elpmaxe@enoemos</span>
