Has anyone setup a Raq4 to use SpamCop? How did you do it? How well does SpamCop work? And, can I use ordb.org also?

If you are looking for Spam filtering you might want to try using MailScanner (http://www.mailscanner.info/) with Spam Assasin and Razor.

Spamcop's service for ISPs is detailed on their site, though it is not the only service of its kind.
