Hello!
INBOX sharing does not seem to work, although all other mailboxes work.
User [email protected] <mailto:[email protected]> has shared a few mailboxes:
# doveadm acl get -u [email protected] <mailto:[email protected]> INBOX
ID Global Rights
[email protected] <mailto:[email protected]> lookup read
write-seen
# doveadm acl get -u [email protected] <mailto:[email protected]> Sent
ID Global Rights
[email protected] <mailto:[email protected]> lookup read
write-seen
# doveadm acl get -u [email protected] <mailto:[email protected]> Drafts
ID Global Rights
[email protected] <mailto:[email protected]> lookup read
write-seen
But user [email protected] <mailto:[email protected]> can't see the shared
INBOX:
# doveadm mailbox list -u [email protected] <mailto:[email protected]>
Trash
Sent
Drafts
Junk
shared
shared/[email protected] <mailto:shared/[email protected]>
shared/[email protected] <mailto:shared/[email protected]>/Sent
shared/[email protected] <mailto:shared/[email protected]>/Drafts
INBOX
A review of the ACL does not explain the behaviour:
# doveadm acl debug -u [email protected] <mailto:[email protected]>
shared/[email protected] <mailto:shared/[email protected]>/INBOX

------------------------------
I don't think it is relevant, but I don't want to forget to mention
that /srv/mail-storage/ is an NFS share.
It would bee nice if someone has a hint. I hope it isn't a bug.
