Spamhaus is announcing this week that they are launching their Domain Block List (DBL). The Spamhaus DBL is a realtime database of Uniform Resource Identifiers (URIs), typically web site domains found in spam messages. Mail server software capable of scanning email message contents can use the DBL to identify, classify or reject spam containing DBL-listed domains and other URIs.

What's this mean for you? Not only are your IP's a thing to watch over when it comes to reputation, but now your domains in your email are also.

Does this count as reputation for domains? In my eyes, YES!

They plan on launching this March 1, 2010.

For those who don't know, The Spamhaus Project is an international nonprofit organization whose mission is to track the Internet's spam operations, to provide dependable realtime anti-spam protection for Internet networks, to work with Law Enforcement Agencies to identify and pursue spammers worldwide, and to lobby governments for effective anti-spam legislation.

Spamhaus maintains a number of realtime spam-blocking databases ('DNSBLs') responsible for keeping back the vast majority of spam sent out on the Internet. These include the Spamhaus Block List (SBL), the Exploits Block List (XBL), the Policy Block List (PBL) and the Domain Block List (DBL). Spamhaus DNSBLs are today used by the majority of the Internet's Email Service Providers, Corporations, Universities, Governments and Military networks.

Comments

I have received several inqueries concerning the Spamhaus Domain Blocking - clients wanting to know if this will impact them, as well managers wanting risk assessments. My standard response is that our clients will not see any change in the email activities, they are not spammers. Personally, I believe that the ability to defeat this methodology is as simple as applying a variant of snowshoeing, in this case, using domains instead of IP's. However, I would please this before the deliverability peerage to shot full of holes as you see fit
