Hi,
In fact you don't NEED a director. You can use two dovecot servers sharing a NFS storage with a normal (backend) implementation. It's good to see that page: http://wiki2.dovecot.org/NFS for some good recomendations.
You must have a base_dir for each instance of dovecot you want to run, and a dovecot.conf as well. One could be director and other backend. I suggest you have two separated configuration directories, /etc/dovecot-director and /etc/dovecot-backend. Each with the respective configuration. Start dovecot with "dovecot -c /etc/dovecot-director/dovecot.conf". Backend is the same.
In order to help more, provide us more details about your environment and doulbts.

Hello, I am currently trying to setup a cluster of mail servers. I currently have two servers I am trying to cluster together. These servers will also have a shared NFS backend. I have read on the site that I will need to configure director since I am using NFS. I have read through all of the documentation on director but still need a little guidance to get things up and running. One of the questions I have is about the base_dir on the Multiple Invocations section of the wiki. It states that I will need to change the bas_dir to the new run directory, not sure what needs to happen here, can anyone help me out?
