vhost domain login

I use NOCC for multiple domains.

I setted up apache vhosts, so every webmail subdomein
ends up in the same directory as NOCC.

I didn't want users must choic there own domain. so I
adapted the login code a little, which checks the
Domain againt the domains in the conf.

I'd like to see my code merged in the source tree, so I
don't have to care when updating NOCC.

code:

else if ( isset($conf->vhost_domain_login) ) {
$i = 0;
while
(!empty($conf->domains[$i]->in))
{
if
(strpos($_SERVER["HTTP_HOST"],$conf->domains[$i]->domain))
echo
"<input type=\"hidden\" name=\"domainnum\" value=\"" .
$i . "\" />\n";
$i++;
}

}
