It's interesting to me that your chosen example of "doing it right" is
in fact doing 2 very wrong things (bl.spamcop.net as a blacklist, and
sender callback).
What's the problem with bl.spamcop.net?
a) poor quality control on the part of spamcop leads to lots of false
positives (listing the wrong host due to improper analysis of the
received header, listing due to inaccurate reports, etc.)
b) poor policies on the part of spamcop leads to lots of false positives
(listing due to various types of autoresponders, etc.)
c) last I checked (which may have changed) even THEY don't recommend
using their blacklist as an actual MTA blacklist, but instead they
recommend it for things like SA blacklist checks (ie. use it for
scoring, not for outright blocking).
