Mailto Redirect Link Things

I was thinking, a cool way to avoid email harvesters that would work quite well is something like this:

<a href="mailer.php" title="Mail me">Mail me!</a>

Then, in mailer.php, have this:

<?php
header('Location: mailto:email@domain.com');
?>

That way, all browsers would redirect to the mailto link, which would open the mail app. Spammers wouldn’t see the email though, and they wouldn’t add it.

Whatcha think?
