Yes, I knew about that. In Courier, we had 'INBOX.' namespace prefix and '.' as a separator. 
Now we have empty prefix and a '/' as a separator.  So, the settings are as follows:

namespace {
  location = maildir:/usr/mailsuite/data/%d/%n
  type = private
  separator = /
  prefix =
  inbox = yes
}

But I used the courier-dovecot-migrate.pl script from Timo, as recommended. Where might be the 
traces of Courier (namespace settings etc.) remained? It seems that Courier and Dovecot use separate
sets of files in user mailbox. Maybe, the migrate script expects the settings to be prefix = 'INBOX.' and
separator = '.', what we don't want, so, we must modify the migrate script to change namespace settings
when migrating?
