I wish I had done that.. :-(

I am not familiar with that, but I can tell you from experience that the nfs
client code in 6.X has issues.. In particular if the server goes down the
client machine doesn't allow you to unmount the volume.. and if you have
programs trying to acces the downed mount, the whole machine may end up
freezing.

We use NFS as our "storage" sever for pop/imap, but use the MTA to deliver
to the machine.

It is for us..
I am even trying to see if we can even pay someone to expedite getting NFS
fixed in 6.
Unfortunately we decided to increase our NFS usage after I had installed 6.X
in a number of new machines.

If there is I have not read about it.

I am fairly new to NFS.. but I am getting the impression that FreeBSD's NFS
is not as mature as other platforms. I also think it has a lot to do with
usage patterns. I have seen mentions of people having hundreds of clients
connected to a single NFS server... yet I see problems with just a handfull
of clients. Maybe the issue is only with the 6.X branch. Sadly part of the
reason I moved some newer machines to 6.X was because of some comments I saw
on how NFS had been improved in 6.X :-(
