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.
