I don't see this.

If you mean horde/ingo/bachend.php this is the content

----------

$backends['imap'] = array(

     'driver' => 'null',

     'preferred' => '192.167.9.244',

     'hordeauth' => true,

     'params' => array(),

     'script' => 'imap',

     'scriptparams' => array(),

     'shares' => false

);

---------

Which script backend do you use?

If I create a Ingo rule with a dot inside the name, ex "plone.it"

the login process stand by for 1 minute.
