dovecot - May 2007 - header-lines of subfolders have to be rescanned after each client startup

Hi all,
after each startup of my different mail clients (thunderbird, outlook, 
...) the contents of subfolders if I click in has to be renewed. This 
takes some time for large folders. I just migrated from courier. And 
there all subfolders were available immediately. Is there something to 
configure?
Another effect regarding subfolders is that the client forgets, which 
subfolders were opened after shutdown and shows the folders closed. This 
means, that necessary subfolders have to be reopened after each startup. 
This was managed  as well by my previous courier server.

Many thanks for answers
Rainer Sigl

Sounds like something's really wrong in here. Are you using NFS? Do you
see dovecot-uidlist file in each subfolder directory? Does it get
changed?

Many thanks,
no, I don't use NFS but it may be a permission problem.
I have virtual users so all the directories belong a artificial user 
'exim' and also group 'exim'. Additionally I saw now that the
file
dovecot-uidlist has the protection 600. The creation date of 
dovecot-uidlist is the date when I synced first time the folders with 
dovecot after installation. But strangely a change of the permissions to 
666 has no effect, dove-cot isn't changed.
A additional info may be that I migrated von courier imap.
So the mainfolder INBOX. and single subfolders have a correct changing 
dovecot-uidlist with 600 and exim exim.
All subfolders below the upper subfolders (.Sent.2005.2-Mar) don't 
change dovecot-uidlist.
