I noticed that Message-ID:
<258c8$42dccd76$513b49d4$24169@news.versatel.nl> from Stephanie
contained the following:
>I tried to add some e-mail vallidation but is fails.
>
>if(!$_POST['email']&&$req_email||ereg("/\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/")){
> $missing[]=$req_email;
> $red[1]=" class=\"red\"";
>
>It only validates if the field is not empty, but not for a valid email
>address.

The first one is a black hole, the second is a typo, the third is not
mine. All would pass as valid with a regex checker. None are valid (in
that you won't get a reply from any of them)
I think it's a bit pointless really. Some forms ask for the email
address to be typed twice then compare the two which /may/ help prevent
typos. But the only way to check if an email address is valid is to
send mail to it, and see if you get a response.
