[horde] Adding shared mailbox in Horde using Dovecot ACL

[Adam Raszkiewicz]

I'm lookin if Horde will be able to do something like: to allow userA
access userB mailbox when userA will login to his/hers mailbox.

Usually (for an IMAP client accessing Dovecot mailboxes) I will add userB
to the userA using dovecot ACL as follow:

doveadm acl add -u userA at domain INBOX user=userB at domain admin create delete
expunge insert lookup post read write write-deleted write-seen

My question is if Horde will allow to access userB mailbox by userA after
adding that way.

Thanks,
Adam
