This extension makes email addresses in autolinks be rendered as something like this:

<a class="protected-email"
   data-email="[email protected]"
   href="javascript:void(0)">Enable JavaScript to see this email</a>

You'll also need to include jQuery and this bit of JS code for the magic to work:

$(document).ready(function () {
    $(".protected-email").each(function () {
        var item = $(this);
        var email = item.data('email');
        item.attr('href', 'mailto:' + email);
        item.html(email);
    });
});
