Many years ago we experienced similar problems with NFS.
The use of NFS made sense under a simpler email services architecture but
begain to fail (i.e., poor IMAP/POP services) as load and user base grew;
adding to the problem was increasing the number of IMAP/POP systems and
using mbox files (we still do, but that's another issue to be resolved).
The solution was to scrap the architecture used for at leat 10 years,
and redesign without the need for any NFS anywhere email is involved.
I understand NFS 4 mitigates or eliminates the locking issues, but we're
not interested anymore...
