		<description><![CDATA[Signing Email is now a Draft Standard! Signing email transitioned from a proposed standard to a draft standard (RFC6376 -- one of the new RFCs) over at the IETF a few days ago. The other is RFC6377.

		<title> Response Policy Zones (RPZs): Use as a Blocklisting Process (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20110613_response_policy_zones_rpzs_use_as_a_blocklisting_process</guid>
		<link>https://circleid.com/posts20110613_response_policy_zones_rpzs_use_as_a_blocklisting_process</link>
		<description><![CDATA[Gradually it seems the word is spreading about a new blocking methodology to interrupt the ability of end users to click and visit phishing sites - thereby having their personal information/credentials at risk. This is the DNS Response Policy Zones. DNS RPZs allows companies that run recursive resolvers to create a zone that will not resolve specific domains. <a href="https://circleid.com/posts20110613_response_policy_zones_rpzs_use_as_a_blocklisting_process">More...</a>]]></description>

		<title> Blacklist Operations and Practices: Excerpts from an ASRG Draft (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/posts20110301_blacklist_operations_and_practices_excerpts_asrg_draft</guid>
		<link>https://circleid.com/posts20110301_blacklist_operations_and_practices_excerpts_asrg_draft</link>
		<description><![CDATA[The Anti-Spam Research Group (ASRG) published a draft for an Overview of Email DNSBL Best Practices. We can take a step back and review paragraph 2.2.5 (Conflict of Interest)... Some DNSBLs used for blocking/negative reputation have had a practice of requiring fees or donations to charities from the listee for delisting. It is generally considered entirely appropriate for a DNSBL to charge for access to it by its users -- the definition of a commercial DNSBL. <a href="https://circleid.com/posts20110301_blacklist_operations_and_practices_excerpts_asrg_draft">More...</a>]]></description>

		<title> Mandatory Provision of Abuse Contact Information in WHOIS (Featured Blog)</title>
		<guid isPermaLink="true">https://circleid.com/postsmandatory_provision_of_abuse_contact_information_in_whois</guid>
		<link>https://circleid.com/postsmandatory_provision_of_abuse_contact_information_in_whois</link>
		<description><![CDATA[An industry professional at Abusix is the backbone behind a proposal to improve and create better mitigation of abuse across different global internet networks. Basically, this introduces a mandatory "abuse contact" field for objects in global Whois databases. This provides a more efficient way for abuse reports to reach the correct network contact. Personally - as a Postmaster for a leading, white-label ISP, I applaud this with great happiness for multiple reasons. I also feel people who handle abuse desks, anti-abuse roles, etc. should closely follow this. <a href="https://circleid.com/postsmandatory_provision_of_abuse_contact_information_in_whois">More...</a>]]></description>
