Hi. I am also interested in a NFS backend. I don't want to share
the NFS partition among servers, so locking should not be an issue.
I found this FAQ, it is old:

I do have a cyrus-2.2 with the mail spool in NFS but the /var/lib/cyrus
in local drive. It runs fine so long. It is even faster than iSCSI in
my hardware.

I guess you already found it, but did you see this thread ?
