Personally, I have *never* received a legit C/R. Every single one that ended up on my machines have been in response to spam sent with a forged sender address.
I wish I could say the same - at work we have at least a dozen clients who use challenge/response, and when it's for business you can't just ignore the challenges, let alone blacklist your clients.
Mailinblack in particular seem to have been quite successful in selling their C/R system to companies here in France... who seem to have totally overlooked the very real business risk of other anti-spam systems classifying their challenges as spam.
