I wouldn't say it's advanced, or I missed some point...
First answer is: There is good documentation about setting up DNS
service around.  (e.g. O'Reilly, DNS and Bind, a really good book)

Second fast answer (if you're using Bind{8,9} zone files):

    $ORIGIN junkemailfilter.com.
    $TTL 10m

    @           IN SOA .... (
                ...
                ...
                )

    
                IN NS NS.REALITY-DNS.COM.
                IN NS REALITY-DNS.NET.
                IN NS NS.REALITY-DNS.ORG.

    ....

    dnsbl       IN NS <your 1st name server for your subdomain>
                IN NS <your 2nd name server for your subdomain>

    ; and do not forget the glue records, if your name servers
    ; are inside the subdomain



    Best regards from Dresden
