spamcop does explicitly not recommend using their RBL for blocking - they 
know why.  That's the downside of a fully automated system.

Every mailserver with more than a few 1000 users are bound to end up on 
spamcop again and again, either because spamcop's header parsing is broken 
(it is, sometimes), or because some users are reporting 'spam' that isn't.

Happy with
 - sbl-xbl.spamhaus.org
 - list.dsbl.org
 - relays.ordb.org
and until recently SPEWS (dropped it because it didn't catch much that 
wasn't caught by the others already.)  I used to use the country based 
blackholes list for cn and tw for a while, but I don't see the need 
anymore.

And, of course, postgrey as the very first line of defense.

Coupled with the usual checking on HELO (blocking 'localhost' HELOs and my 
own IP does wonders!), SMTP protocol conformance (pipelining), sender 
(envelope) address checking.
