Mail Account Migration Script gives errors

Hello everyone,

to help migrating the mail accounts from one server to another, a good friend of mine wrote a script using the Remote API.
First of all, here's the code:

PHP:

function check_login($username, $password) {
  $result = false;

  $authOK   = "235 ";
  $ehloEnd  = "250 ";
  $password = base64_encode($password);
  $username = base64_encode($username);

  $socket = fsockopen("85.214.88.184", 25, $errorNo, $errorStr, 60);
  if ($socket) {
    $input = fgets($socket);
    fwrite($socket, "EHLO Kibo.FM\n");

    do {
      $input = fgets($socket);
      $done  = (stripos($input, $ehloEnd) !== false);
    } while (!$done);

    fwrite($socket, "AUTH LOGIN\n");
    $input = fgets($socket);
    fwrite($socket, $username . "\n");
    $input = fgets($socket);
    fwrite($socket, $password . "\n");
    $input = fgets($socket);

    $result = (stripos($input, $authOK) !== false);

    fwrite($socket, "QUIT\n");
    fclose($socket);
  } else {
    $result = "Keine Verbindung zum Server";
  }
function create_mail($email, $emailpass){
  $username = 'webservices';
  $password = 'password';
  $soap_location = 'https://37.221.195.129:8080/remote/index.php';
  $soap_uri = 'https://37.221.195.129:8080/remote/';

  $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 />';
        }

        //* Set the function parameters.
        $client_id = 1;
        $params = array(
                        'server_id' => 1,
                        'email' => $email,
        'login' => $email,
                        'password' => $emailpass,
                        'name' => $email,

                        );

        $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 (isset($affected_rows)) {
    return true;
  }else{
    return false;
  }
}
$email = $_POST['email'];
if(isset($_POST['email'], $_POST['passwort'])) {
  if (check_login($_POST['email'], $_POST['passwort']) == 1) {
    if (create_mail($_POST['email'], $_POST['passwort'])){
      echo "Das E-Mailkonto wurde erfolgreich &uuml;bertragen";
            $empfaenger = "[email protected]";
            $absendername = "Mail Move Script";
            $absendermail = "[email protected]";
            $betreff = "Mailpostfach umgezogen";
            $text = "Hallo Sascha,
                     Die E-Mailadresse $email wurde umgezogen.";
            mail($empfaenger, $betreff, $text, "From: $absendername <$absendermail>");
        echo "<br>";
        echo "Falls sie noch weitere Postf&auml;cher umziehen m&ouml;chten, klicken Sie bitte hier:";
        echo "<br>";
        echo "<a href='mail.html'>Weiteres Postfach umziehen.</a>";
    }else{
      echo "Das E-Mailkonto wurde schon &uuml;bertragen";
    }
  }else{
    echo "Das angegebene Konto konnte nicht gefunden werden oder die Daten sind nicht korrekt";
  }
}
?>


Now, creating mailboxes with this script gives the following errors on the target server:

Code:

Mar 19 18:12:01 moon dovecot: deliver([email protected]): sieve: failed to open logfile (LOGGING TO STDERR): open(/.sieve.log) failed: Permission denied (euid=5000(vmail) egid=5000(vmail))

Mar 19 18:21:00 moon dovecot: deliver([email protected]): dict quota: Quota update failed, it's now desynced

In what way do I have to alter the code? Or is there a general problem?

Kind Regards
