[Pkg-exim4-users] USING RBL question

[exim4]

Greetings,
 I am coming from years of Sendmail, and am investigating the possibility
of using EXIM as a possible replacement. I have read every doc/wiki/info/how-to
I could get my hands on. As such I now find myself with more questions than
answers. Which is what brings me here.
I suppose I should preface this question with the following:

OS debian etch (current)
ARC x86 (32bits)
EXIM4 exim4-daemon-heavy
exim4-conf-type single-conf

OK, that being said, I'm attempting to use RBL's to help filter out spammers.
I read the suggested how-to located at:
http://www.pseudorandom.co.uk/2006/mailserver/
which is great but begins by providing directions for both split and single,
but suddenly drops single instructions/references at the RBL (dnslists)
entry. I did my best to try and find and add the correct entry/ies. But
didn't feel confident enough to follow through. So I went to all the RBL's
I'm currently using on my Sendmail boxes to seek instructions. However,
none of their instructions line up with the current *debian* configs. So
here I am. OH. I also couldn't find the /examples/ that were mentioned
in several places during my investigations.
Anyway, to the point; Would anybody be willing to post an example RBL
entry with a reference to it's whereabouts in the conffile?

Thank you for all your time and consideration in this matter, and apologies
in advance should this be considered excessive noise.
