Probleme with replication and shared mailbox
Dear Dovecot Users/Admins/Mailing-List
First of all I would give a big thanks for your great work !
I may need your help to find out what?s going on with my replication and shared
mailbox problem.
I setup a full active/active servers with :
* Postfix
* Dovecot
* MariaDB (automaticaly balanced/failover between the 2 host within DRBD and
Heartbeat)
* SpamAssassin
* Clamav
* Sieve
* Webmail
* IMAP Over SSL and SMTP Over TLS
* Fail2ban

##################################################################################################
2.2.27 (c0f36b0) ==> DEBIAN 9 Stretch (no back ports)
##################################################################################################
Everythink works fine until I activate a share on a mailbox.
I run the following command to share the full mailbox ? websentinel ? to ?
lbrault ? (because of ? acl_defaults_from_inbox = yes ? set in conf) :
==> doveadm acl set -u websentinel at example.fr INBOX user=lbrault at
example.fr admin create delete expunge insert lookup post read write
write-deleted write-seen
Just after activation of share and connect through webmail client (Horde in this
case but tried Roundcube also) I get this kind of error messages on logs :

In parallele to this error some new folders are created on the mailboxes root
with name containing ? nonexistent mailbox? ? :

When I look at the GUID it seems this GUID are linked to the folder into the
shared mailbox (websentinel)
I tried to change dsync params with the following command into 10-master.conf to
exclude the shared folder from replication but it seems having no effect with
the TCP replication :
==> replication_dsync_parameters = -d -N -l 30 -U -x shared
Here is my dovecot -n report :

I would share a special thanks for Community help ?
If more conf files needed (ie postfix main.cf) please ask me for them.
Best regards
