I've finally solved this "problem". There is no problem in horde code, it was just a configuration issue. After properly configuration of servers.php:
'quota' => array( 'driver' => 'cyrus' ) in my firsts tests everything works as expected (with both courier and cyrus drivers), with no changes. Thanks for the answers. Aaaaaaaaaagur. -- Joseba Torre.
