Hello!
I finally took the time and spent two days to set up replication for my server and now I have a question or two.
I initially set noreplicate userdb field to 1 for all but a test user, but I could still see in the logs that all mailboxes were trying to connect to the other server via SSH. Is that normal?
Jun 22 16:55:22 host dovecot: dsync-local(user@host.ee)<>: Error: Remote command returned error 84: ssh -i /home/vmail/.ssh/vmail.pem -l vmail backup.host.ee doveadm dsync-server -D -u user@host.ee
Then I ended up setting mail_replica in userdb for only my test user, but I could still see in the logs that it was trying to sync the others as well, despite mail_replica being 0 for the rest.
Jun 22 20:52:59 host dovecot: doveadm(user@host.ee): Fatal: -N parameter requires syncing with remote host
I also notice (and read from recent posts) that sieve script replication doesn't work at all.
Dovecot v2.3.6 and Pigeonhole from the official Dovecot CentOS repo.
Thanks, Reio PS: Getting SSH for Dovecot to work with SELinux on CentOS 7 was fun as usual. :)
