Can't unsubscribe from public mailbox when dsync multi-master is enabled
Hello,
I am trying to build a dovecot environment with 2 servers with dsync
master<->master replication. Everything works just fine, one can login
in any of the servers and see and manage their mails. The problem I
see is that one can not unsubscribe from public mailboxes.
Let's call the servers server1 and server2, both of them have an imap
webui pointing to localhost, just to make the test easier.
One subscribes to a public mailbox connected through the webui on
server1. A few seconds later the same user can see the subscribed
mailbox on the webui on server2 just as expected, but if he tries to
unsubscribe it will not work. The public mailbox folder will still be
subscribed to and visible. There is absolutely nothing on the logs,
but I know it is related to the dsync replication because if I
shutdown any of the servers, I will be able to unsubscribe just fine,
UNTIL the shutdown server is powered back on and replication starts
again, and, in this case, the previously unsubscribed public mailbox
will just reappear.
Is this a bug or am I missing something in my configuration?
Thanks!
