I've created an anchor link about this issue at:

http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block

Matthias, are you able to block/return no answers or return a last octet of 255
as a blocked answer. And NOT return purposefully wrong answers?

If so, a rule like this would work, yes?

ifplugin Mail::SpamAssassin::Plugin::DNSEval
  header RCVD_IN_DNSWL_BLOCKED eval:check_rbl_sub('dnswl-firsttrusted',
'^127\.0\.\d+\.255$')
  describe RCVD_IN_DNSWL_BLOCKED ADMINISTRATOR NOTICE: The query to DNSWL
was blocked. See http://wiki.apache.org/spamassassin/DnsBlocklists#dnsbl-block
for more information.
  score RCVD)IN_DNSWL_BLOCKED 0.001
  tflags RCVD_IN_DNSWL_BLOCKED nice net
endif
