[horde] Vacation error

[Felix Haehner WE DO]

Hello,

i have a problem with the vacationrule.
If i try to save and enable the rule i got the following error message:

"script not updated: there was an error activating the script. the 
driver said: connection refused"

how can i fix that?

For your information this is my backends.local.php setup in the 
/ingo/config folder.

<?php
$backends['imap']['disabled'] = true;
$backends['sieve']['disabled'] = false;
$backends['sieve']['hordeauth'] = true;
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['hostspech'] = 
'mail.wedo-berlin.com';
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['logintype'] = 
'PLAIN';
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['usetls'] = true;
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['port'] = 4190;
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['scriptname'] 
= 'ingo';
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['debug'] = true;
$backends['sieve']['script'][Ingo::RULE_ALL]['params']['utf8'] = true;
