I don't use SpamCop but I do use Spamhaus' SBL and occasionally
Yahoogroups will get listed there too. So I put their host name in my
hosts whitelist file which exempts them from the DNS check:

  deny    message = Mail from $sender_host_address currently not  \
                        accepted here as it is listed in the Spamhaus SBL/XBL \
                        ( $dnslist_text ).  If this listing is in
error, please contact \
                        (my postmaster address) to request a whitelisting. \
                        Please visit (my website) for more details.
          hosts = !+relay_hosts
          hosts = !+whitelist_hosts
          hosts = !+whitelist_hostips
         !authenticated = *
          dnslists = sbl-xbl.spamhaus.org


My whitelist entry for Yahoogroups contains this:

*.bulk.scd.yahoo.com

This should work even if Yahoogroups changes or adds IPs, they'd still
use the same hostname pattern.
