Hmm?  I guess the problem is due to your misunderstanding of the

A "name-based" DNSBL, aka RHSBL or right-hand-side BL, is a DNS zone
where you list domain names, just like ip addresses in DNSBL or
IP-based BL.  That is, instead of testing for,
you test for example.net.example.com.  Your mail software should have
support for RHSBL to check host NAMES against it, not IP addresses.
Examples of RHSBLs are several lists of rfc-ignorant.org, rhsbl.sorbs.net,
rhsbl.ahbl.org and others.
