Replication Issue

[Jorge Canto E.]

Hello, I've been trying to set up replication, Server A is dovecot 2.2.32
(upgrade from 2.0.9) and Server B is dovecot 2.2.10, I use mysql as userdb,
I don't want to replicate every user on my database only especific users so
I set my iterate_query on dovecot-sql.conf.ext file; my problem: doveadm
replication is not "reading" my iterate_query, it tries to replicate every
user.

Diagnosis:
- I removed iterate_query from dovecot-sql.conf.ext, on the log file I can
see the doveadm replication is still trying to replicate.

- doveadm user '*' shows error (obvious) there is not iterate_query but, on
the log files I can see replication is trying, why doveadm replication is
trying to replicate? what userdb is reading from?

doveconf -n

I really appreciate your help
