dovecot - Feb 2014 - SMTP configuration for director mail cluster

HI All,

I have setup my Dovecot director proxies and Dovecot backend mail
stores.? I intend setting up several incoming and outgoing Exim
MTA's.? I am a bit confused about what I need to run on the backend
Dovecot MTA's to get the incoming mail delivered to them.? Do I need
to install Exim on them or use LMTP to receive mail from the MTA's??
Also, can I directly deliver mail to the mailstores or do I have to go
through the director proxies using lmtp?? Note that I am using
Director with the mailboxes on NFS backed storage.

Thanks

Murray

Backend needs to run dovecot lmtp service listening on a TCP port.

There is no need for exim on the backends Delivery can be done by lmtp.

You will need to go through director lmtp proxy service in order to connect to
the correct backbend. Local delivery should not be used in the director setup.
If you deliver locally to the wrong NFS client, you will likely corrupt your
mailbox indexes on NFS.
