So, which is the imap root directory? 
I am getting conflicting definitions from the documentation (copied 
below)...
------------------------
mbox storage requires detecting 
INBOX location and IMAP root directory. If
MAIL environment points 
to file (+rw) it's treated as the INBOX file. If it
points to 
directory (+rwx) which contains .imap/ (+rwx), inbox (+rw) 
or
mbox (+rw) it's treated as IMAP root directory. If INBOX 
isn't known,
imap_root/inbox file is used by default. If root directory isn't 
known, we
try to find it from /, ~/mail or ~/Mail.
Files created 
by Dovecot
------------------------
.subscriptions: One folder per 
line listing subscribed IMAP folders.
There's only one of these files in the 
root mail directory (~/Maildir/ 
or
~/mail/.imap/). 
----------------------------------------------------------------------------------
My .subscription file is located in ~/mail/ but the documentation states only one should be in ~/mail/.imap/ !!!!
Thanks,
