New blocklisting process

There is a new type of blocking designed to interrupt the ability of users to click and visit phishing sites.
DNS Response Policy Zones allows companies running recursive resolvers to create a zone that will not resolve specific domains. This is a second layer of filtering, if a spammer manages to get an email with a malicious link into the inbox then the ISP can still protect the user from becoming a victim from the scam. For more detailed information about RPZ, check out the helpful slides published by ISC.
Two blocklists announced this morning that they were publishing lists in RPZ format so ISPs can import the data into their DNS recursive resolver. SURBL is currently offering their list as RPZ. Spamhaus is currently running a beta for the DBL in a RPZ format. If you’re a current DBL user, talk to Spamhaus about checking out their new format.
