	There have been enough "wrong" solutions to this problem with
no correction to warrant a response (I usually avoid posting on the assumption
that I am the 100th one to say the same old thing)

	The "right" way to share /usr/spool/mail over NFS is for the 
clients to forward the mail to the server "via" SMTP!  Use mail protocols
for mail,  and file protocols for files!  This has many advantages:

1)  You do not have problems with allowing root access or restrictions
on the number of clients.

2)  The locking should work more reliably.

3)  With a little work (a few MX records) you can stop running "sendmail -bd"
on the client all together,   the client sendmail.cf (sample enclosed)
can be barebones simple!

	The only catch is to make the server recognize mail bound for the 
clients as "local",  you must define a class containing all the clients
you serve,  and resolve all members of that class to the local mailer,
talk to the nearest sendmail "guru" !

	Here is my "trivial" client sendmail.cf file,  works on
Irises,  NeXTs,  Suns,  Mips and Decstations,  (the master sendmail.cf
is much less portable,  trips over bugs in the various versions)
