php - ISPConfig Bulk Mail add with SOAP fails with domain does not exists although it does exist -

i tried adding mailadresses saved in txt file, 1 per line, following code

<?php require 'soap_config.php';  $datei = "address.txt"; // name der datei $adresse = file($datei); // datei in ein array einlesen  $client = new soapclient(null, array('location' => $soap_location,             'uri'      => $soap_uri,             'trace' => 1,             'exceptions' => 1)); try {     if($session_id = $client->login($username, $password)) {             echo 'logged successfull. session id:'.$session_id.'<br />';     }     foreach ($adresse $zeile) {     //* set function parameters.     $client_id = 1;     $params = array(             'server_id' => 1,             'email' => $zeile,             'login' => $zeile,             'password' => 'password1!',             'name' => $zeile,             'uid' => 5000,             'gid' => 5000,             'maildir' => '/var/vmail/domain.tld/'.$zeile,             'quota' => 268435456,             'cc' => '',             'homedir' => '/var/vmail',             'autoresponder' => 'n',             'autoresponder_start_date' => array('day' => 1, 'month' => 7, 'year' => 2012, 'hour' => 0, 'minute' => 0),             'autoresponder_end_date' => array('day' => 20, 'month' => 7, 'year' => 2012, 'hour' => 0, 'minute' => 0),             'autoresponder_text' => 'hallo',             'move_junk' => 'y',             'custom_mailfilter' => '',             'postfix' => 'y',             'access' => 'n',             'disableimap' => 'n',             'disablepop3' => 'y',             'disabledeliver' => 'n',             'disablesmtp' => 'n'     );      $affected_rows = $client->mail_user_add($session_id, $client_id, $params);     echo "new user: ".$affected_rows."<br>"; }     if($client->logout($session_id)) {             echo 'logged out.<br />';     } } catch (soapfault $e) {     echo $client->__getlastresponse();     die('soap error: '.$e->getmessage()); }; ?> 

if run code following error

logged successfull. session id:83f678adsafa9f37b5qw47rrf73c3a97<br /><?xml version="1.0" encoding="utf-8"?><soap-env:envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/"><soap-env:body><soap-env:fault> <faultcode>mail_domain_does_not_exist</faultcode><faultstring>mail domain - domain.tld - not exist.</faultstring></soap-env:fault></soap-env:body></soap-env:envelope> soap error: mail domain - domain.tld 

if try adding address writing soap file works fine. idears might have missed?
