Hello,
I've a Dovecot Server Version 2.2.30.2 running on CentOS 6.9 and there's a problem with acls on shared folder. We have some mailboxes which are shared and used as a "group mailbox" and also some user who share their inbox and only the inbox when they are on holiday e.g.. When I set
"acl_defaults_from_inbox = yes"it's not possible to restrict the access to only the inbox, meaning that the user who wants to share only their inbox have to share the whole mailbox. On the other hand when I set
"acl_defaults_from_inbox = no"it is not possible to create a folder direct under the inbox of a "group mailbox" and one gets a "permission denied" message. Is this the normal behavior normal? Although the user who wants to create the folder has all rights he gets a "permission denied" message? Why? Am I missing something important? Does anyone who uses shared mailboxes had the same problem and solved this? Any suggestion or information, that I probably miss is welcome.
If needed here's my Dovecot configuration:
