RBL can be tested with rblcheck utility.
http://sourceforge.net/projects/rblcheck/

Check contents of ./file, find some IP address for testing and check it
with rblcheck.

I suspect that basename in /var/qmail/control/rbllist should not be
127.0.0.1. It should point at DNS server responsible for some real domain.

For example, you run 'example.com' domain and create rbl.example.com NS
record in your example.com zone file pointing at your rbldnsd server. Then
basename is rbl.example.com.
