Hi Gerald, Thank you for the details. As per your suggestion, I have made the changes to dovecot.conf file. Still I don't see any replication is happening. Please see the dovecot.conf file.
I do not see "/etc/dovecot/conf.d/12-replication.conf" in my servers. So I had put everything in the dovecot.conf file only. Please see the complete data in it below. The below data is in server A. In other server (server B) Also I have the same configuration, except mail_replica line and it is pointing to the other server like, " mail_replica = remote:vm...@bal3200dev001.testorg.com ". I have generated/configured the ssh keys also for vmail user in both servers. Now When i manually ssh to the server, it is not asking for a password. ===================== ===================== disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log #mail_location = maildir:/z1nfs/mail/virtual/%d/%n/Maildir/ mail_location = maildir:/z1devenv/mail/virtual/%d/%n/Maildir/ passdb { args = /etc/dovecot/passwd driver = passwd-file } pop3_uidl_format = %g protocols = pop3 imap #ssl = yes #ssl_cert = </etc/pki/dovecot/certs/dovecot.pem #ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { # args = uid=vmail gid=vmail home=/z1nfs/mail/virtual/%d/%n args = uid=vmail gid=vmail home=/z1devenv/mail/virtual/%d/%n driver = static } mail_debug = yes verbose_ssl = no # Enable the replication plugin globally mail_plugins = $mail_plugins notify replication service replicator { process_min_avail = 1 } dsync_remote_cmd = ssh -l%{login} %{host} doveadm dsync-server -u%u plugin { mail_replica = remote:vm...@bal3200dev002.testorg.com } service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service replicator { unix_listener replicator-doveadm { mode = 0600 user = vmail } } replication_max_conns = 10 ===================== ===================== Am i missing anything here? Please guide me. Thanks, Kishore Potnuru On Fri, Jul 17, 2020 at 12:36 AM Gerald Galster <list+dove...@gcore.biz> wrote: > > I have done the sync manually with "doveadm sync" command.
