   Can I do this with mail?  Can I mount /usr/spool/mail everywhere and

   still use sendmail, or should /bin/mail be all I need with a special
   sendmail.cf on the 'main' machine?
   Has anyone done this?  Am I off-track?

We've been doing it for over 18 months.  Works fine.  I recommend,
however, that you install a modified /bin/mail which [a] doesn't give
up on open(2) failures, in case the mail-housing host goes down (we
soft-mount) and [b] uses the old-style /usr/spool/mail/username.lock
style of locking, since flock(2) doesn't work across NFS.

I put together our /bin/mail from the Pyramid OSx and SunOS 4.0
versions.  As for fooling the system into thinking that all mail comes
from one host, the sendmail.cf I use believes that everyone is
username@cis.ohio-state.edu - we hide hostnames entirely.  You can't
tell where it was written without peeking at the Received: headers.
