No, you only need to point your Listserv machine at a DNS that's properly
configured.  Installing your own is just adding to the confusion unless you
actually really understand how to run a DNS - if you're trying to work around
the fact that your site has 2 DNS servers that don't agree on what's going on,
adding a third is just gasoline on the fire.

Having said that, I'll note that often, running a *caching-only* DNS on the
Listserv machine is a big performance win because it often saves you a network
round-trip or three to look up an A or MX record.  But that's a performance
optimization only - it has the same view of the world as whatever DNS server
it's pointed to for resolving queries.
