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.


dovecot-uidlist is supposed to be 0600. Are the imap processes running
as "exim" user as well?
yes they do. imap are running as 'exim', imap-login as 'dovecot'

Don't you see any errors in Dovecot's logs (see
http://wiki.dovecot.org/Logging)?

no, nothing apparent.
I just changed the log configuration as in you weblink that dovecot logs are written in separate files


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.


dovecot-uidlist changes only when new messages arrive or when existing
messages are expunged. So I guess it's normal that in archived Sent
boxes the uidlist isn't modified.
ok, maybe dovecot-uidlist is ok so. But why my client has to rescan?
