I disagree.. spamcop definitely used to be much too aggresive, but for the past few months I have used them at MTA reject level and have no known FPs. This is on a site with about 10k users/about 1 million msg per day, and they usually let me know pretty quickly when there's a problem. I do use dnswl.org to whitelist before RBLs. You might still not want to use spamcop to reject if you're paranoid (and I'll agree they've been overly agressive in the past), but I think it's very safe to use in SA. btw this article is what convinced me to give spamcop a second look: http://www.dnsbl.com/2007/05/spamcop-bl-another-look-its-accurate.html -Aaron
