[Dovecot] header-lines of subfolders have to be rescanned after each client startup

[Rainer Sigl]

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
