There is, of course, a way of avoiding all of this pain.

In the config file use
    spool_directory = /var/spool/exim/${primary_hostname}


or something similar, make sure the logs are in a similar location, and
run each machine in its own spool directory.

If a machine dies, then you start another exim queue runner with a
fractionally modified config file (maybe the possibility of setting these
variables on the command line should be looked at??).

Then you don't *really* have shared directories, your locking problems
disappear in a puff of logic, and you have a decent solid spool area.
You are still canned if your NFS server dies, but then so are we (for
different reasons).

    Nigel.
