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).Actually, sometime in the past several months, SpamCop's FP rate dropped dramatically. I'm not privy to the inside details, but they must have made some dramatic changes. Therefore, whatever bad FP reputation they've earned over the years should be erased and they should be reassessed.
