[Dovecot] Director (was: Hints for a NFS-Setup)

Hi again,

I tried to setup a test invironemnt like this:

MTA --(lmtp)--\ /--(lmtp)--> backend1 --
-- director -- -- NFS MTA --(lmtp)--/ \--(lmtp)--> backend2 --/

IMAP-User --> frontend1 --\ /--(imap)--> backend1 --
-- director -- -- NFS IMAP-User --> frontend2 --/ \--(imap)--> backend2 --/

but now I'm very confused. Is it actually possible to setup a host (or two) as a director only or will I have to enable the director service on each frontend and MTA?

Is anyone using a similar setup and could post his configuration for the different hosts?

Happy Easter! Patrick
