I would reconfigure that cluster so that only one machine delivers and
all the rest deliver to it - this has many advantages - single point of
management (the pain caused by mislaligned alias files is horrid),
single delivery process etc.

Yes, within the limits of NFS. NFS locking is not reliable enough to
stake your career/life/marriage/testicles on. It just ain't no matter
what the sales people tell you.

I used to run a mail system with NFS mounted spool on Sun systems (Suns
do good NFS locking). It occasionally lost/corrupt mail.
