Email::getdiskusage

[didacrios]

I'm doing tests with the xmlapi.php and trying to use the getdiskusage function

The documentation http://docs.cpanel.net/twiki/bin/view/ApiDocs/Api2/ApiEmail#Email::getdiskusage says that the input parameters are domain and login but didn't work when trying to acces

$opts = array(
    'domain' => "domain.com",
    'login' => "mail-user",
);

print $xmlapi->api2_query($server_login, "Email", "getdiskusage", $opts);

Returns:

{
    cpanelresult: {
        data: [
              {
                  user: null,
                  domain: "domain.com",
                  login: null,
                  diskused: "0"
               }
           ],
          module: "Email",
          apiversion: 2,
          func: "getdiskusage",
          event: { 
               result: 1
         } 
    }
}

But when i use the paramters user instead of login it works OK
