Sieve again: addessing subfolders

[Thorsten Schnebeck]

Hi list,

I have a problem so address an existing subfolder of my kolab-1.0 server with 
sieve.
My testuser is called user at host.com. I made a vaild sieve script, put this by 
kiosieve on the server and marked the executable flag. The script trigger 
correctly but the fileinto command failed if I use a subfolder of INBOX:

lmtp connection preauth'd as postman
Jun 10 20:20:04 <debug> lmtpd[9107]: duplicate_check: 
<200406101901.44158 at erwin.ingo-kloecker.de> user at host^com^_Entwurf 0
Jun 10 20:20:04 <info> lmtpd[9107]: sieve runtime error for user at host^com id 
<200406101901.44158 at erwin.ingo-kloecker.de>: Fileinto: Mailbox does not exist

Script:

require "fileinto";
if header :contains ["List-Id"] ["kde-pim.mail.kde.org"] {
  fileinto "INBOX.user at host^com._Entwurf";
}

My /kolab/var/imab/spool is

user/user\@host\^com/
|-  _Entwurf
|-  _Gesendet
|-  _Post
etc.

So far I tried
fileinto "INBOX._Entwurf"; (this is like it is in every sieve example script,  
but: Mailbox does not exist)
fileinto "_Entwurf"; (Mailbox does not exist)
fileinto "user.user at host^com._Entwurf"; (access denied))
fileinto "INBOX/_Entwurf"; (Mailbox does not exist)
fileinto "INBOX/user at host^com/_Entwurf"; (Mailbox does not exist)
fileinto "INBOX"; ( works :-} )

How do I adress subfolder of users with a Kolab naming scheme in sieve?

Bye
