Which kernel are you using on the *NFS* server ?
We had NFS locking issues with the kernel shipped with SL5.2
and some of the updates.
We don't seem to get them with 2.6.18-92.1.22.el5

It may be that your macs don't see the problem because they are
being less picky with the locks.
For us the broken locking made mutt very unhappy with an NFS
mounted /var/spool/mail but we found no problems with pine.
