Hi everybody,

I am honestly desperate: I have spent/invested the whole day in trying to set a shared mailbox, with quite partial success. The INBOX is merged with the top level mailbox, and there are many more folders. To give an idea, for the shared account sharedacc@domain.org, this is how looks the folder structure:

sharedacc |-folderA |-folderB \-folderC

in the account for usera@domain.org, I see the following:

usera |-folderD |-folderE |-folderF \-shared \-sharedacc

So, I do not get to see folderA, folderB, folderC, etc.

My configuration is:

# 2.2.25 (7be1766): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.4.14 (099a97c)
# OS: Linux 4.5.4-0 x86_64 Debian stretch/sid zfs

mail_plugins = zlib expire acl

plugin {
acl = vfile
acl_shared_dict = proxy::acl
}

dict {
acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
}

namespace {
list = children
location = mdbox:/mnt/vmail/%%d/%%n:INDEXPVT=/mnt/vmail/indexes/shared/%%d/%%n
prefix = shared/%%n/
separator = /
subscriptions = yes
type = shared
}

protocol lmtp {
mail_plugins = zlib expire acl sieve
}

protocol imap {
mail_plugins = zlib expire acl antispam imap_acl
}

the files I have one the account for sharedacc are: sharedacc |-dovecot-acl |-dovecot-acl-list \-mailboxes |-dovecot-acl |-folderA | \-dbox-Mails | \-dovecot-acl |-folderB | \-dbox-Mails | \-dovecot-acl \-folderC \-dbox-Mails \-dovecot-acl

In dovecot-acl-list I have the following contents: 1474920778 folderA 1474920778 folderB 1474920778 folderC

and in every dovecot-acl, I have: user=usera@domain.org akxeilprwts

All the files on the filesystem are owned by the same vmail user. What is strange is that I can see all these folderA, folderB, folderC in roundcube, and I can click to subscribe to them. However, when I go back to the general view, the subscriptions have been reset and I see only sharedacc, without a thing inside. Finally, in kmail I can see the subscribed folders without a problem (??!)

Can please somebody help me?
