Hi,
I am trying to deploy large e-mail system but I will use qmail-ldap on Linux and maildir will be mounted by all backends from Netapp via NFS.
In LDAP, there will be only one mailhost entry. All qmail-ldap backends will have same name and will run dovecot instance. So, all users can access to mailbox from any server in the pool. If I distribute users with different mailhosts and if one mailhost server is down, the users will not able to access their mailbox until fix the problem or change mailhost entry with working one.
But I don't know the NFS issues in my planned setup. Do you think that I will face same NFS locks/problem(OS based) with Netapp NFS?
Thanks in advance.

We're planning to deploy a large e-mail system storing maildirs in a NAS system through NFS. One of the options we're thinking on is using Dovecot+EXIM.
As far as I've read in both project's documentation, both services implement locking allowing multiple servers to access the same maildirs in order to distribute the service load.
Mail deliveries don't require any locks with maildir. But for Dovecot, be sure to read http://wiki.dovecot.org/NFS
