looks like ingo has a problem saving the ruleset to the uncommon  
preference backend KolabImap.

what works:
  - I see a last login time
  - I could configure the Horde Portal page and the selected portal  
blocks survive logout/login cycles.

In both cases a new "file/message" is created in users mailbox under  
the folder
".Benutzereinstellungen"

I have also turba installed and configured to host the prefs backend, too.
If I create a new contact, a second "file/message" is created in the  
mentioned mailbox.

But If I create a new filter rule I also expect it's stored in the  
preference backend.
Funny: the rule is pushed as sieve file to the mailserver
but not visible inside ingo :-/

I temporary switched to File prefs backend and then anything goes as expected.

Any advice?
Thanks
