preg_match email only allowed from certain domain

[cmap]

we want people to be signed up "really" within the company ie. we know [e-mail] is john brown we don't know [e-mail] is.

adding -
if (!preg_match('/\S+/', $email)) $msg .= '<b>No email address specified</b><br />';
elseif (!preg_match('/^{[a-zA-Z0-9-]+(.[a-zA-Z0-9-]+)@.(mycompany.com)$/',} $email)) $msg .= '<b>Invalid email address</b><br />';

but not quite there. Anyone help ?

do you need to use preg_match? for something this simple, you should be able to use the string operators...

thought about this myself, and was going to work it out, but just found the following example in the php manual

$email = '[e-mail]'; 
$domain = strstr($email, '@'); 
print $domain; // prints @example.com

ref: strstr()

If you know the domain an even easier way might be:

if (substr($email_address, -13) == "mycompany.com") { it was valid ... }

Obviously change the 13 to reflect how many characters are in your domain name.
