    That’s really useful. I’ve been using the code below. I usually comment out the domain check below (get by host name function) because it occasionally fails on a valid domain. I don’t know why…

    if( !eregi(“^[a-z0-9]+([_\.-][a-z0-9]+)*”.”@([a-z0-9]+([.-][a-z0-9]{1,})+)*$”,$mail, $regs) )
    {
    echo(“I’m sorry, ‘$mail’ is not a valid mail address.n”);
    die();
    }

    elseif( gethostbyname($regs[2]) == $regs[2] )
    {
    echo(“I’m sorry, but ‘$regs[2]‘ is not a valid domain.n”);
    die();
    }
