We are currently facing the problem, that dovecot doesn't return any

cur and new directory (maildir format). The logfile does not contain
any information other than login/logout.After I deleted the dovecot.index file, all messages are available
and everything works as expected. According to the wiki page [1] the
main index file should be synchronized when the cur and new
timestamps changed. I suppose this synchronization doesn't work
correctly because the problem still existed after I changed the
timestamps manually.
Did you check that the timestamp also really changes in the server
Dovecot was running on? Could be a NFS caching problem.
