Just figured it out:

In the file wp-includes/pluggable.php, find the function wp_notify_moderator, and at the end, replace this line:

@wp_mail($admin_email, $subject, $notify_message);

with this:

$q = mysql_query("SELECT user_email FROM wp_users WHERE ID = " . $post->post_author);
	$q = mysql_fetch_assoc($q);
	@wp_mail($q['user_email'], $subject, $notify_message);
