Setting up replication?

23 Mar 2016


      I'm trying to set up replication between two servers and I've hit a
snag.  I have two users and am using mbox files.  If anybody has a
sample config file for a simple system like mine I would really be
grateful to see it.
Thanks,
The error I'm getting is:
Mar 23 14:07:31 knute2 dovecot: doveadm(192.168.3.100,nobody): Error:
user nobody: Initialization failed: Namespace '':
mkdir(/nonexistent/mail) failed: Permission denied (euid=65534(nobody)
egid=65534(nogroup))
Mar 23 14:07:31 knute2 dovecot: doveadm(192.168.3.100,nobody): Error:
dsync-server: User init failed
Mar 23 14:07:31 knute2 dovecot: doveadm(nobody): Error: sync: Failed to
start dsync-server command: 75
knute@knute2:/etc/dovecot/conf.d $ sudo doveadm user '*'
nobody
knute

I don't know why the user 'nobody' shows up here?  nobody is in the
/etc/passwd file but he has no group.
knute@knute2:/ $ cat /etc/passwd | grep nobody
nobody:x:65534:65534:nobody:/nonexistent:/usr/sbin/nologin

I created a separate config file as suggested in Peer Heinlein's book.
