Hi,

i have a problem configuring cyrus backend in a almost traditional
murder setup.

I have one master process which starts the forntend and backend services.
The forntend services use /etc/imapd_fe.conf as config file and listen
on the external network interface and the backend services listen to
the internal network interfaces and use /etc/imapd_be.conf

The lmtpdproxy delivers the mail to the backend using lmtp over tcp.
The backend lmtpd asks the mupdate server where the mailbox is,
which results in the "wrong" answer that the mailbox is remote.
The backend tries to proxies the mail to an other lmtpd
on the same backend. This results in an infinite loop.
I tried this with 2.4.6 and 2.3.16.

AFAIK the backend config must contain the mupdate_server
because create mailbox, rename mailbox and delete mailbox
information must be send to the mupdate master.
But if mupdate_server is configured lmtpd will ask
the mupdate_server where the mailbox is, which will always
result in an "remote mailbox" as answer

What do i need to change?

If you're running 2.3.x on your frontends and 2.4.x on your backends,
you need to upgrade your frontends.

Both frontend and backends where running 2.4.6 in the first try.
But after the fist problems i suspected a bug, as this setup was
working on a test system with an early 2.3.x some time ago.
So i tried this setup with 2.3.16. but it has the same problems.
