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,
