Okay, I was worried not to check some api methods or a special global 
arrays which would tell me the hostspec.
So I can make it perhaps more efficient when I take the session:

$rv_aut = $GLOBALS['registry']->getAuth('bare');
require dirname(__FILE__) . '/../../imp/config/backends.local.php';
foreach ($_SESSION['imp'] as $key => $val) {
   if($key == "0server_key"){
    foreach ($servers as $key2 => $IMAPServer) {
         if ($key2 == $val){
                 $rv_host = $IMAPServer['smtphost'];
                 break;
         }
    }
    }else{
    break;
   }
}

$backends['smb'] = array(
     'disabled' => false,
     'name' => 'Dateiablage',
     'driver' => 'smb',
     'hordeauth' => true,
     'params' => array(
         'hostspec' => $rv_host,
         'port' => 139,
         'share' => $rv_aut,
[...]
