I think so:

horde/ingo/config/conf.php:
<?php
/* CONFIG START. DO NOT CHANGE ANYTHING IN OR AFTER THIS LINE. */
// $Id: 48142d13ef06c07f56427fe5b43981631bdbfdb0 $
$conf['storage']['driver'] = 'prefs';
$conf['rules']['userheader'] = false;
$conf['spam']['header'] = 'X-Spam-Level';
$conf['spam']['char'] = '*';
$conf['spam']['compare'] = 'string';
/* CONFIG END. DO NOT CHANGE ANYTHING IN OR BEFORE THIS LINE. */
