Send Comment Email Notification Only From Specific Users

Hey, atuhbta, yep this is definitely possible.

Please see my sample PHP code below:

/*Sends email notifications only if from a specific commenter*/
add_filter('notify_post_author','notice_from_specific_users', 10, 2);
function notice_from_specific_users ( $maybe_notify, $comment_ID )
{
	$commenter_email = get_comment_author_email( $comment_ID );
	$wanted_email_addresses = array ( "example@example.com" ); 
	$maybe_notify = (! in_array ( $commenter_email, $wanted_email_addresses )) ? false: true; 
	return $maybe_notify;
}

This will only send an email notification if the desired email address is included in the $wanted_email_addresses array.
