Do you have any particular reason for not just running majordomo on one of
them and having all of the others forward to that specific one?
If you really do want to share the load across the servers, than the
question is how NFS (or whatever you are using) safe are the MJ writing
operations. I suspect that they are not.
Therefore, I would have all operations that involve writing into the
majordomo directory restricted to one machine. So that will include
everything except for actual posting. So mount the MD directory read-only
on all but one of the hosts. On the read-only ones set up your aliases so
that what you need for posting (the list address itself, the out-going
aliases) will be the same everywhere. But for everything else (request
addresses, archiving aliases) will all point to the one host that has the
read/write mounted directory.
Anyway, this is off of the top of my head, and propably isn't all that
helpful.
Where I've had lists that had multiple MXes for the domain for the list, I
just had one host do all of it and all of the other MXes just forward on
all the MD stuff to that one host.
