This DNSBL ists any kind of Backscatterer seen at the UCEPROTECT-Network. Unfortunately many and also big providers do still backscatter. They are flooding you with misdirected bounces and misdirected autoresponders and sender callouts but will almost always send legit mail too.
We monitor this blacklist since 2015-01-01. More information: http://www.backscatterer.org/
