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:vmail at
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:vmail at 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
