Regarding the given information, it seems to me that the option "mail_shared_explicit_inbox=no" does not work as expected.
Quote from NEWS-2.2: mail_shared_explicit_inbox setting to specify if a shared INBOX should be accessible as "shared/$user" or "shared/$user/INBOX"
Using Dovecot 2.2.13 and Maildir++ Working on the commandline:
# doveconf mail_shared_explicit_inbox mail_shared_explicit_inbox = no
# service dovecot restart
# ls -lda /mail/reader/Shared/owner@example.com/.* Shows no (hidden) folders.
# telnet 127.0.0.1 143 a0 login reader@example.com *** a1 list "" "Shared/owner@example.com"
- LIST (\Noselect \HasChildren) "/" Shared/owner@example.com a1 OK List completed.
Is the retrieved "\Noselect" tag correct with the option "mail_shared_explicit_inbox = no"? I would expect the folder "Shared/owner@example.com" to be "selectable", because I thought the option "mail_shared_explicit_inbox = no" would make e-mails of a shared INBOX visible directly at the folder "Shared/owner@example.com" (which does not work in my case).
Note: Shared *sub*folders of an INBOX work as expected. Just to show that the shared INBOX is accessible (note that it is not shown by a list "" "*" here, which is expected with that option):
a2 list "" "Shared/owner@example.com/INBOX" a2 OK List completed.
a3 select Shared/owner@example.com/INBOX
- FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
- OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.
- 27 EXISTS
Using "mail_shared_explicit_inbox = yes" does show the INBOX as a subfolder of "Shared/owner@example.com" and allows accessing the e-mails of the shared INBOX. However, it would be nice (and keep users happy at using their known shared folder layout) to see the e-mails of the shared INBOX at the Shared/owner@example.com folder.
