If you need one for an email address (here's something i came across in my functions file, not sure who's it is, but it's not mine)

PHP Code:


			
function check_email($email) 
{
    if(preg_match('/^\w[-.\w]*@(\w[-._\w]*\.[a-zA-Z]{2,}.*)$/', $email, $matches))
    {
        if(function_exists('checkdnsrr'))
        {
            if(checkdnsrr($matches[1] . '.', 'MX')) return true;
            if(checkdnsrr($matches[1] . '.', 'A')) return true;
        }else{
            if(!empty($hostName))
            {
                if( $recType == '' ) $recType = "MX";
                exec("nslookup -type=$recType $hostName", $result);
                foreach ($result as $line)
                {
                    if(eregi("^$hostName",$line))
                    {
                        return true;
                    }
                }
                return false;
            }
            return false;
        }
    }
    return false;
}
