dovecot - Sep 2010 - kmail-error: can't upload folder (imap-account on dovecot-server)

Hello,

I've some trouble with my kmail (Version 1.13.5 / KDE 4.5.1, Kubuntu 10.04
and
a dovecot-imap-server on debian etch (dovecot 1.0.rc15-2etch5).

Everytime I try to create a folder under my imap-inbox, I get an error like 
"can't upload folder...", but after this message I can see a new
folder under
my inbox-folder, but I can't use it ...

With a thundermail-client I can create a subfolder without any erro and I can 
use it r (but only first level).

My conf:
# /etc/dovecot/dovecot.conf
log_path: /var/log/dovecot/dovecot.log
info_log_path: /var/log/dovecot/dovecot.log
disable_plaintext_auth: no
login_dir: /var/run/dovecot/login
login_executable: /usr/lib/dovecot/imap-login
login_greeting: Herzlich Willkommen, %u.
mail_location: mbox:~/mail
imap_client_workarounds: outlook-idle tb-extra-mailbox-sep
auth default:
  passdb:
    driver: passwd-file
    args: /etc/passwd.dovecot
  userdb:
    driver: passwd


The reason for using debian etch and dovecot 1.0 is the hardware: it's
running
on a Fritzbox-Router, and there is actual a littlebit trouble with lenny 
(often crashing, reboots of the whole box etc.)

I hope, someone can help me ...

Thanx and greetz,

Christoph

Though I don't anticipate this will solve your prime issue, we were 
able to (still) somewhat update Dovecot on a Debian Etch box using the 
Archive at Debian; we used these:

Apparently, the backports repository can still be used (no updates):

Under the normal mbox storage layout, you cannot have mailboxes 
(folders) which contain both messages and child mailboxes (subfolders). 
The reason is explained in detail at the beginning of 
http://wiki2.dovecot.org/MboxChildFolders .

So with your present set-up you won't be able to create a folder under 
INBOX.

You can create folders at the top level, but you won't then be able to 
make subfolders in those.

To be able to nest folders freely, you could:

1. Switch your mail storage to one of the other formats: Maildir 
(Dovecot 1.0 onwards), single-dbox (Dovecot 1.2 onwards), multi-dbox 
(Dovecot 2.0 onwards).

2. Use a specialist scheme (Dovecot 2.0 onwards) to allow free nesting 
under mbox - see http://wiki2.dovecot.org/MboxChildFolders

Also worth noting that the current stable version of Dovecot is 2.0.x.

To be able to get best help on the mailing list, I would say try to use 
at least version 1.2.x of Dovecot.

This is not even 1.0+, this is 1.0rc15, which was notoriously buggy...

*Not* upgrading should really not be an option, and you will get little
meaningful support until you do...
