Almost. You cannot have the actual mail queue on NFS, or Bad Things Will
Happen[tm].
What you want to do is to have a separate Qmail install on each swerver.
You can even install Qmail one one machine, verify that it works, then
just tar up everything under /var/qmail, and unpack the tarball on each
swerver (of course, there cannot be any messages in the queue directory
when you do that).
If you want to, /var/qmail/bin can be a soft link to an NFS directory, but
that doesn't really buy you much. You can also set /var/qmail/control to
a soft link to a shared NFS directory, if all your swervers are configured
identically. Even if you have one or two control files that need to be
different for each machine, such as "me", you can have
/var/qmail/control/me to be a soft link to /etc/qmail/me, for example, and
create this file on each machine, initializing it to its hostname.
