The people running OpenDNS have launched a new service called PhishTank. Like OpenDNS, PhishTank is a free public service wherein one can view, submit and verify phishing websites.
OpenDNS then employs the PhishTank verified phish data in its free recursive DNS service as one source among many to identify phishing sites to block for its DNS users.
An API is also available for using the PhishTank data by third party applications
