Hello,

we have a setup here where the main (and only important) feature of the IMAP server is the public folder. Two Dovecot instances are running in a active/passive cluster and mailstorage should be replicated between the two.

Since there is a race condition when using public namespaces (locking on user level and not on mailbox level) I had the intention of limiting the replication to one user.

I read somewhere that dsync is replicating all the users the command "doveadm user '*'" shows. And the command only shows *one* user because I have modified the iterate_query:

,----[/etc/dovecot/mysql.conf] | iterate_query = SELECT username AS user FROM mailbox WHERE username = 'data_replication@example.com' `----

root [~]# doveadm user '*' data_replication@example.com root [~]#

So, why does Dovecot still replicate mails from other users inboxes? And why does doveadm replicator still show other users?

root [~]# doveadm replicator status '*' username priority fast sync full sync success sync failed data_replication@example.com none 00:57:14 01:13:21 00:57:12 - arne.hoffmann@example.com none 00:20:04 00:31:40 00:20:02 - root [~]#

[I removed some whitespace to keep line length in check]

Any explanation of this behavior would be just awesome. Hints to possible solution even more! :)
