New blacklist: SPFBL

Leonardo from SPFBL shared the following information with me and I thought it would be useful to share it here with folks.

Status of bad.psky.me: QUESTIONABLE

Noted and respected spam filterer Spamhaus is indicating that they believe the the Protected Sky (bad.psky.me) blacklist is "fraudulent." They report that Protected Sky is "an anonymously-run DNSBL service which was pirating [Spamhaus] data and republishing it as its own work." Spamhaus further indicates that Protected Sky doesn't follow DNSBL best practices as indicated in RFC6471.

Status of anonwhois.org: DEAD

I first blogged about the ANONWHOIS blacklist back in 2010. It was very useful to identify domains were ownership information was cloaked from the public. Why? Because many of us in the anti-spam and security community think that for a domain being used for commercial purposes, it isn't right to hide who the owner is. And this obstruction to transparency is often exploited by bad guys who send spam and malware, to try to make it harder to identify them.
