{
include_once("error.inc");
die();
}

You do realise this will make a lot of valid emailadresses invalid? =

Domains are not limited to the ascii set for instance, and [a-z0-9'._-] =
=

are not the only valid characters in an email name.
Also, it's recommended to use the preg_* functions instead of ereg*

Hmmm? I often use my spambucket hotmail address (see my mailaddress :) )=

but I normally won't unless I just registered with that mail / about onc=
e =

every 1 or 2 months)

if(preg_match('/@(hsbc|barclays|hotmail)\.com$/i',$email)){
//the code

// Receiving variables
@$email =3D addslashes($_POST['email']);

if (! ereg('^[*a-z\'0-9]+([._-][*a-z\'0-9]+)*@([a-z0-9]+([._-][a-

==================== ==
Thanks for the help :)

For info this is just for a whitelist that we have created for users
to add email addresses into.
Although I do not wish for *@hotmail.com to come through I do wish for
user@hotmail.com to come through.

Any guidance on using the " * " not as a wildcard... ??
if(preg_match('[*]/@(hotmail... ??

Thanks,
J

if(preg_match('/\*@(hotmail|rbs|barclays|lloydstsb|hsbc|natw est)\.(com|
co\.uk)$/i',$email)){

Found I only needed to add \*

So all sorted and working a treat :)
