Sure. If you just want to block addresses of some domains, you do not even need to use regular expressions. Try something like this: $block = 'jhgfghjk.com'; $email = $_POST['email']; if(substr($email, -strlen($block)) === $block) { do whatever you want to not accept this address; } If you iterate this code over a list of blocked domains taken from an array, you have implemented a generalized black list. -- Regards, Manuel Lemos PHP professionals looking for PHP jobs http://www.phpclasses.org/professionals/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/
