just reading from sidelines,
looking at my own inbox (formerly CourierIMAP> D1 > D2)
I see some of 'legacy' dir tree folders as so:

...
drwx------   5 vmail vmail     4096 Dec 24 07:09 .Drafts
drwx------   5 vmail vmail     4096 Nov 25 23:27 .ebay
drwx------   5 vmail vmail     4096 Nov 25 23:24 .INBOX.Drafts
drwx------   5 vmail vmail     4096 Nov 25 23:25 .INBOX.Sent
drwx------   5 vmail vmail     4096 Nov 25 23:27 .INBOX.Sent.2008.01
drwx------   5 vmail vmail     4096 Nov 25 23:27 .INBOX.Sent.2008.02
...

it all seems to work, BUT, to keep me happy, can I just rename from the
shell respective folders to get rid of INBOX where is exists...? or it
that a bad idea..?


# cd /etc/dovecot
# grep INBOX *
dovecot.conf:    autocreate = INBOX
dovecot.conf:    autosubscribe = INBOX

# grep inbox *
dovecot.conf:    inbox = yes
