OK, I am running (for many years now) an existing courier_imap maildir++
setup with exim as the MTA.

I set up a namespace for dovecot, using the wiki as a guide, so:
namespace private {
separator = .
prefix = INBOX.
location = .
inbox = yes
hidden=no
}
However, clicking on the folder does not show any messages at all.
dovecot is not creating a subscription file inside the maildir
(Mail.app does not allow you to subscribe to folders -- it subscribes
to all existing folders for you)
And if I try and create a new folder inside the account I get a
"CREATE" command failed, server error:  unknown namespace
This is what we're using and our Courier maildirs are able to work with Dovecot...
default_mail_env = maildir:~/
namespace private {
separator = .
prefix = INBOX.
inbox = no
}
namespace private {
separator = .
prefix =
inbox = yes
hidden = yes
}
Also, here are patches to make Dovecot use Courier's subscription file properly...

src/lib-storage/index/maildir/maildir-storage.h:
-#define SUBSCRIPTION_FILE_NAME "subscriptions"
+#define SUBSCRIPTION_FILE_NAME "courierimapsubscribed"
