Same problem here!

With the latest Debian jessie version 1:2.2.13-5 you can actually have a
per user mail_replica setting taken from a (LDAP) directory.  This keeps
the duplicate mail issue away from other users but a few willing to
test ...

I read in Peer Heinlein's Dovecot book
http://www.opensourcepress.de/de/produkte/Dovecot/13560/978-3-95539-074-7
that replicating a public namespace gives you trouble :-(. So keep the
"-N" option away for now.

However I would like examples for the "-n" and "-x" options, which are
neither given in the wiki nor in the nonexistant man page.

I think the replication feature is very, very cool, but right now it
gives me a hard time to implement flawlessly ;-)

Thanks for any help or light shed on this issue ...

Cheers Jan
