Replication not working

Hello,

I am trying to setup replication between two Mac OS X El Capitan Server.  I have added the field as I could understand from the replication page of dovecot and from a few poste in the mailing list.

The mac uses the system user _dovecot as main system account.  I have setup ssh keys between the two systems for the two _dovecot servers.  SSh works fine from the terminal.

But yet, I get these messages in the log file :

Mar 09 20:18:44 auth: Error: od[getpwnam_ext](submit): No record for user
Mar 09 20:18:44 doveadm: Error: Host key verification failed.
Mar 09 20:18:44 dsync-local(submit): Error: read(_dovecot at laposte.mycompagny.com) failed: EOF
Mar 09 20:18:44 dsync-local(submit): Error: Remote command returned error 255
Mar 09 20:23:44 auth: Error: od[getpwnam_ext](submit): No record for user
Mar 09 20:23:44 doveadm: Error: Host key verification failed.
Mar 09 20:23:44 dsync-local(submit): Error: read(_dovecot at laposte.mycompagny.com) failed: EOF
Mar 09 20:23:44 dsync-local(submit): Error: Remote command returned error 255

and so on every few minutes.

I have a few things about which I am not sure.  We configure port 12345, but nothing listen on that port.   The doveadm_password, what is it exactly ?  Should I use a distinct account than _dovecot for synchronisation (all the fields that need to be added for replication) ?  

Here is my configuration, any help would be appreciated :
