kola 2.4 sieve / roundcube

[GrK]

Hi there,

I can't find the way to make work the managesieve plugin for roundcube.

I telnet the sieve server at 4190 and it answer. but my roundcube 
client tells me 'unable to connect to sieve server'.

I tryed a lot of search through google but that didn't helped me.

Here is the sieve telnet answer :
[root at mail conf.d]# telnet localhost 4190
Trying ::1...
Connected to localhost.
Escape character is '^]'.
"IMPLEMENTATION" "Cyrus timsieved v2.4.16-Kolab-2.4.16-1.el6.kolab_2.4"
"SASL" ""
"SIEVE" "comparator-i;ascii-numeric fileinto reject vacation imapflags 
notify include envelope body relational regex subaddress copy"
"STARTTLS"
"UNAUTHENTICATE"
OK


And here is my managesieve.inc.php file

<?php
     $rcmail_config['managesieve_port'] = 4190;
     $rcmail_config['managesieve_host'] = '%h';
     $rcmail_config['managesieve_auth_type'] = 'PLAIN';
     $rcmail_config['managesieve_auth_cid'] = null;
     $rcmail_config['managesieve_auth_pw'] = null;
     $rcmail_config['managesieve_usetls'] = true;
     $rcmail_config['managesieve_default'] = '';
     $rcmail_config['managesieve_mbox_encoding'] = 'UTF-8';
     $rcmail_config['managesieve_replace_delimiter'] = '';
     $rcmail_config['managesieve_disabled_extensions'] = array();
     $rcmail_config['managesieve_debug'] = true;
?>

Someone have an idea ?

Thx
