FraudBL is, since june 22, an active resolver. Tornevall Networks has in active for tests and currently we’ve seen a positive result of the activation. More information about bitmasking will in short get updated at http://docs.tornevall.net/x/AoA_/. In short, we will also activate the new default database for dnsbl.tornevall.org.
You can still contact dnsbl@tornevall.org for blacklisting support.
