Using the Spamcop BL *solely* as the basis for rejecting mail is a sure way
to lose wanted email. From Spamcop's website:
"... SpamCop encourages use of the SCBL in concert with an actively maintained
whitelist of wanted email senders. SpamCop encourages SCBL users to tag and
divert email, rather than block it outright."
"The SCBL is aggressive and often errs on the side of blocking mail...
Many mailservers operate with blacklists in a "tag only" mode, which
is preferable in many situations."
IMO, the best use of the SCBL is as a scoring metric with Spam Assassin.
Additional discussion should be directed to SPAM-L.
