Ok, tahnk you.

I will do that.

Yes. This is a support question, not a bug report.

So, I've to create new filters on Ingo web interface?

You can't. You have to write the rules through the interface Ingo 
provides, it can't read existing (compiled) rules from Sieve.

Yes, I  already have Sieve on my remote server. How can I import the 
existing filters on my remote server to Ingo?

Thank you.

If I understand correctly, you already have Sieve filters on your 
server and attempt to use Horde to configure there. Ingo doesn't work 
that way. It can only add/modify/remove filters you created in Ingo, 
existing Sieve scripts can't be modified this way.

I've one problem with filters. I have the sieve enabled and configured 
to running on remote host and port 4190, but it seems my horde don't 
this information to get my filters.

My backends file have this configuration:

$backends['sieve'] = array(
     'disabled' => false,
     'transport' => array(
         Ingo::RULE_ALL => array(
             'driver' => 'timsieved',
             'params' => array(
                 'hostspec' => 'server3',
                 'logintype' => 'PLAIN',
                 'usetls' => false,
                 'port' => 4190,
                 'scriptname' => 'ingo',

                 'debug' => true,
             ),
         ),
     ),
'script' => array(
         Ingo::RULE_ALL => array(
             'driver' => 'sieve',
             'params' => array(
                 'utf8' => true,
              ),
         ),
     ),
     'shares' => false
);

Thank you
