function wpse61431_settings_validate($args){
    //$args will contain the values posted in your settings form, you can validate them as no spaces allowed, no special chars allowed or validate emails etc.
    if(!isset($args['wpse61431_email']) || !is_email($args['wpse61431_email'])){
        //add a settings error because the email is invalid and make the form field blank, so that the user can enter again
        $args['wpse61431_email'] = '';
    add_settings_error('wpse61431_settings', 'wpse61431_invalid_email', 'Please enter a valid email!', $type = 'error');   
    }

    //make sure you return the args
