I think it's pretty extreme to block based on a BL these days.
You can also simply assign it a score that may or may not tip the
scale towards spaminess.

Y'all are acting like something new or different started happening
here. Cisco has owned Spamcop since 2007. Don't be fooled by the hand
coded HTML look, it's been corporate owned since 2003.

Spamcop's BL has always been too binary, if you're worried about
accepting legit mail from large providers who also emit some non-zero
amount of unwanted mail. Block the whole IP or don't, there's no other
option. It's a reputation model defined back in the late 90s (you
know, back when some of us first got involved in that whole spam
fighting and email blocking thing) and as we see here, it has
limitations. It's probably a big part of why, for example, Gmail (and
other smart folks) cares so much about domain reputation today -- it
makes it easier to identify reputation at a level deeper than just the
sending IP address.

If you're going to use the Spamcop BL for blocking, it's never NOT
going to work this way. Today the complaint is Microsoft, tomorrow it
will be somebody else.
