replicator: User listing returned failure

7 May 2018


      Hello.
I've tried to configure TCP replication to slave server. But I got some
errors...
mx1:~# dovecot --version
2.2.27 (c0f36b0)
From dovecot.log:
May 07 19:27:41 auth-worker(34348): Warning: mysql: Query failed,

From slave:
mx2:~# cat /etc/dovecot/conf.d/90-replication.conf
# use tcp:hostname as the dsync target
plugin {
mail_replica = tcp:mx1 # use doveadm_port
}
As I can see nothing happens automatically.
But mx2:~# doveadm -D sync -u abuse@example.com -d -N -l 30 -U

successfully executed and getting mails from mx1.
