My users put that authority in my hands, they dont want to deal with it and they dont have the time.
I use the blacklists because it makes them happy, and they dont care if that single email is blocked, because only an idiot would rely 100% on email for something major.
Well basicly most my users have the same with the default settings. But if they need to make sure a "friend" bypass any filters they have the power to do that. And to also raise there default score reject level. Or ban addresses. See what incoming email messages were rejected, etc. etc.
Now this is done with newer mail server software (I use Surgemail). That doesn't require a full time mail admin changing settings, managing black/white lists for his end users.
They have something like that already.

And its a scam that spamcop came up with. google "spamcop bondedsender"
You have a good idea, but it would be abused. Who would control this? Some US goverment agency? Some new ORG thats just a front for the US gov like ICANN (ie; US DoC)?
The best way to stop spam is to get people from purchasing crap from spam mailings. Just like JUNK POSTAL MAIL.
IMHO
Sure you could have handled it, To be honest Spamhaus is mostly using other peoples dnsrbl's anyway. I get alot more out of tqmcube.com or cbl.abuseat.org than the Spamhaus's. Plus you should never be rejecting from these lists anyway, just scoring and allowing your users to decide what should be rejected.
