That is not correct! If localhost runs a caching DNS server, it will fetch DNS information from forwarding DNS servers, which can be the ISP's, Google's, whatever. The whole point of having a local caching DNS server is that it not only takes care of using all DNS servers it knows about to fetch data, but also to store that data and prevent DNS-lookup-heavy applications (like E-Mail servers) to generate lots of additional traffic and overhead.
So, if Marek runs a local DNS server and still gets problems, then we need to look at that config. If not, he really should install a caching DNS server (named, djbdns, etc.) In any case, resolv.conf is just fine only pointing to the local server.
