It's been a while since I mucked with Linux as a NFS server, I've been on Netapp for a while. There may be less knobs than I recall.
I do have one more idea I'll throw out there. Everything I've got here is virtual. I only have the one Dovecot/Postfix server running now, and the impression I get from you all is that that should be adequate for my load. What would the collective opinion be of simply removing the NFS server altogether and mounting the virtual disk holding my messages directly to the dovecot server?
If you're not planning on doing some sort of HA failover or load balancing, and have the option to make your storage direct-attached instead of NAS, it might be worth trying. There's not much to be gained from NFS in a single-node configuration.
