Spamhaus: yes. Use zen.spamhaus.org (you might end up needing to pay for it, and use a local cache, if you're a heavy traffic site, but, frankly, it's worth paying for).

Spamcop: no. Don't use them as an MTA RBL. I'm leery of even using them as a SA RBL, but it's a very bad idea to use them as an MTA RBL (too many false positives). Received on Tue Oct 9 13:07:57 2007
