Yes this would be ideal.

Yes well between Phils' new book and
http://www.ja.net/CERT/JANET-CERT/mail/mail-abuse/rbl-plus-guide.html#otherMAPS

I am reading lots of documentation, sometimes it can be a little
confusing though.

Am I right in thinking that if I want all combinations except 127.1.0.2
then I need to specifically put in the following

127.1.0.1 RBL 127.1.0.3 DULRBL 127.1.0.4 RSS 127.1.0.5 RSS RBL
127.1.0.6 RSSDUL 127.1.0.7 RSSDULRBL 127.1.0.8 OPS 127.1.0.9 OPS RBL
127.1.0.10 OPS DUL 127.1.0.11 OPS DULRBL 127.1.0.12 OPSRSS 127.1.0.13
OPSRSS RBL 127.1.0.14 OPSRSSDUL 127.1.0.15 OPSRSSDULRBL


that is what seems to be implied from the above web page and what you
say.
