You can put them wherever you wish, as long as you include that part
of your configuration. Myself, I'm still using a single dovecot.conf,
only.

If I'm not mistaken, you can use a single ssh user, and you could use
the vmail user for instance. That's what I do, and I'm using sqlite for
userdb.
Here's my configuration:
-----------------------------------------------------------------------
If you choose to run ssh on a different port from the default one, you need:
## ssh command line used in dsync replication (ssh port added)
#
dsync_remote_cmd = ssh -p 1234 -l%{login} %{host} doveadm dsync-server -u%u
-l%{lock_timeout} -n%{namespace}
If not, you can start here:
## --- DSYNC REPLICATION ----------------------------------------
#
# aggregator, replicator, doveadm, and config needed, and
# dsync_remote_cmd if running ssh via non-default port
#
service aggregator {
# give enough permissions for mail processes
#
fifo_listener replication-notify-fifo {
user = vmail
mode = 0600
}
unix_listener replication-notify {
user = vmail
mode = 0600
}
}
service replicator {
# start replication at startup
#
process_min_avail = 1
}
service doveadm {
# if you're using a single virtual user, set this to start ssh as vmail
# (not root)
#
user = vmail
}
service config {
# needed to grant access to /var/run/dovecot/config for service doveadm
#
unix_listener config {
user = vmail
}
}
The following part is for server 1, only:
## --- PLUGINS ----------------------------------------
#
# dsync replication plugin
#
plugin {
# this host replicates to remote host
#
mail_replica = remote:vmail@server2.domain
# run full synchronization mode every other hour
# (default is every 24 hours)
#
replication_full_sync_interval = 1 hours
}
The following part is for server 2, only:
## --- PLUGINS ----------------------------------------
#
# dsync replication plugin
#
plugin {
# this host replicates to remote host
#
mail_replica = remote:vmail@server1.domain
# run full synchronization mode every other hour
# (default is every 24 hours)
#
replication_full_sync_interval = 1 hours
}
HTH,
