Problem with e-mail replacement script

[Anon]

This script is used in a page but NOT in a
form. How would I use it, then? The $_GET
variable is coming up empty, so I get a
mailto: of "info@"...

<?
// email.php
// usage:
//
// <A HREF="email.php?to=me&domain=mydomain.com">E-Mail Me</a>-->
//
//
if(!isset($GET['to']))
{
$GET['to'] = "info";
}

if(!isset($domain))
{
$_GET['domain'] = "mydomain.com";
}

$to = $GET['to'];
$domain = $GET['domain'];

$email_address = $to."@".$domain;

// send email header to page
header ("Location: mailto:$email_address");
?>

Ok, found out the solution but have another question...

<?
// email.php
// usage:
//
// <A HREF="email.php?to=me&domain=mydomain.com">E-Mail Me</a>-->
//
//
if (!isset($to))
{
$to = "info";
}
if(!isset($domain))
{
$domain = "austinmetrobaseball.com";
}
$email_address = $to."@".$domain;
// send email header to page
header ("Location: mailto:$email_address");
?>

Now, my browser comes up with a mailto: in
the address bar. How do I prevent that? Like
this:

<A HREF="email.php?to=me&domain=mydomain.com" target="_new">E-Mail Me</a>

Wouldn't that bring up another window? How would I prevent that?

Basically, I just want to "hide" the email
addresses on my site...

take off the target="_new" would prevent the window from opening

Yes, but the current window has been cleared and the mailto: is in the address bar...
