InternetX: Weiterleitungen per XML API eintragen

…. sieht so aus (aus dem PDF entnommen)

<?php
 define( 'HOST', 'https://gateway.autodns.com' );
 define( 'XML_FILE', 'request.xml' );
 $xml = implode( "", file(XML_FILE) );
 header( 'Content-Type: text/xml' );
 echo requestCurl( $xml );
 function requestCurl( $data ) {
 $ch = curl_init( HOST );
 curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
 curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
 curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE );
 if( !$data = curl_exec( $ch )) {
 echo 'Curl execution error.', curl_error( $ch ) ."\n";
 return FALSE;
 }
 curl_close( $ch );
 return $data;
 }
 ?>

Das XML sieht so aus:

<?xml version="1.0" encoding="utf-8"?>
 <request>
 <auth>
 <user>yyyyyyyyyy</user>
 <password>xxxxxxxxx</password>
 <context></context>
 </auth>
 <task>
 <code>0501</code>
 <redirect>
 <type>domain</type>
 <mode>http</mode>
 <source>www.source-example.com</source>
 <target>www.target-example.com</target>
 </redirect>
 </task>

Die Login Daten sind korrekt, warum bekomme ich dies zurück?
