DNSBL for backscatter - Any use?

Hi

What are your thoughts, please, on a dedicated DNSBL being setup which deals 
with backscatter / misdirected autoresponders and C/R's?

I understand that bl.spamcop.net and a couple of the others may have this 
built in. However, I don't believe such a dedicated DNSBL exists at the time 
of writing.

Thanks
