adnsrblcheck is a DNSBL check tool that I wrote sometime in 1999. At the time I had come across the ADNS resolver library and I wanted to try it out. So I grabbed a copy of rblcheck (then at version 1.4) and modified it to use ADNS instead of the standard resolver library.
In December 2008, and while I was supposed to be performing ns2 simulations, I was struck by a severe case of structured procrastination which led to me picking up the tool again and doing some minor modifications. Eventually I pulled myself together, dealt with the deadlines and (almost) forgot about the tool. That is until today: adnsrblcheck, a DNSBL check tool using ADNS, is available again and you can grab it via subversion from here:
svn checkout https://rainbow.cs.unipi.gr/svn/adnsrblcheck
