Another way of doing this is to use ``mh'' or something like it, where mail
is stored on a central server and fetched when the user logs in.  That way,
no need to worry about NFS locking much at all.

That's what I fo here -- all hosts run a local sendmail, but all unqualified
mail (no @host) goes to a central server, which is known as packrat.vorpal.com
or vorpal.com.  All off-site mail is tagged with the @vorpal.com address as
well, unless someone tweaks the sendmail process.
