false positives from spamcop.net?

[Jeff A. Earickson]

I've had a rash of spamcop blocks from sites deemed too critical
for sendmail DNSBL blockage (eg Maine State Government, Yahoo lists,
a local ISP) so I had to demote spamcop from a sendmail DNSBL down
to the "Spam List =" line in MailScanner.  I replaced spamcop in my
DNSBL with sbl-xbl.spamhaus.org, no complaints so far.
