I have Exchange 2007 running in our organization and finally decided to setup IP blacklist providers.  We use Sophos email filtering now and it sometimes helps and sometimes doesn't. I setup bl.spamcop.net and tested it but any provider I use and I enter the IP address in it comes back false.

You could try disabling and re-enabling the blocklist providers in the management console or restart the exchange transport service, I've found these actions have resolved similar issues in the past.

No luck. Still says false. it acts like it times out.

May be worth checking dns - run some nslookup tests on the exchange server to ensure it can see spamcop. Also may be worth testing with other block lists such as spamhaus or sorbs to see if the problem is limited to spamcop itself.
