dnswl.org
dnswl.org is a collaborative effort for whitelisting known-good senders. It is different from other whitelisting services like eg Habeas in that there is no business model involved. dnswl.org is a community-driven project -- it reduces the effort for whitelisting which is otherwise required for each mail system. Instead of everyone whitelisting basically the same senders, we do it once and everybody can profit.

[edit] Zones/Formats
- The data is available as a DNS Whitelist in the list.dnswl.org zone
- The data is also available for download/rsync in a variety of formats (rbldnsd, BIND, Postfix, and a generic format).
- Specialised zones and formats can be created upon request.
Data is categorized by industry (eg "Banks", "Government", "Providers") and assigned different scores ("none", "low", "med", "hi"). Categories and scores are also available through DNS.
The SpamAssassin configuration is available at http://www.dnswl.org/tech

[edit] dnswl.org News
- Thanks for your help
Two months ago, we wrote a “Call for Help” for dnswl.org – and got more response than one would expect! We got offered four additional nameservers, of which two are already in production (and due to which we now have to improve our nameserver operation handling – one of the more comfortable problems to have…) There is a good number of co-administrators being active. If you contacted the admins via mail or via the request form, you should have noticed a shorter ... - dnswl.org - calling for your support
[This article is cross-posted to the two blogs at http://news.dnswl.org/ and http://matthias.leisi.net/ and to the dnswl-users mailing list] Currently, most of dnswl.org is run by myself with the help of some volunteers (“backup” administrators should I ever be run over by a bus) and some organisations. dnswl.org has gained traction since it’s inception in October 2006, and it’s data is now being used by a number of anti-spam solutions (eg filtering applications, blo ... - dnswl.org - usage increasing
Two weeks ago I wrote that dnswl.org has more than 5’000 users. Well, that’s a thing of the past. As of today, August 4th 2007, there are more than 12’000 users of dnswl.org (see the original article on the caveats with such numbers). The increase is “bumpy”, indicating lower useage on weekends (parallel with the lower email traffic usually seen outside working days). This page shows the charts and numbers for three of the nameservers for the list.dnswl.org ... - Announcement: New categories in dnswl.org
Over the past weeks, we continued to enhance dnswl.org data not only by adding more “good” mailservers, but also by refining the categories we assign to these entries. The latest additions are the “Manufacturing/Industrial” (127.0.13.* response code) and “Retail” (127.0.14.* response code) categories. If we add a new category, existing entries may take some time until they are re-assigned. - Whitelisting, taken to the next step
The Karmasphere project is an “open platform for sharing reputation data”. Amongst other data sources, it uses dnswl.org data to determine the reputation of IP addresses and domain names. Karmasphere is still in beta, but looks quite promising – and it started to use dnswl.org data in a way we didn’t even think was possible, namely based on the domains we publish alongside the individual network ranges. As a consequence, we will slightly enhance the data we process for ... - dnswl.org now has more than 5'000 users
Yesterday, July 16th 2007, dnswl.org passed the mark of 5’000 users. And as of mid last week, we list more than 10’000 individual IP addresses and networks as “good” mailservers. You can see the number of networks and hosts querying dnswl.org here (and at the very bottom of that page, you will find a link to the metadata statistics) "dnswl.org now has more than 5'000 users" vollständig lesen - Metadata changes and additions
Starting from today, DNSWL records include a country code. Not all entries are already “enriched” with this information. It is planned to make this information available through DNS in the future. Currently it is only available through the search on the main website. Three category descriptions have been changed: “Bank, (Re-) Insurance” → “Financial Services” “Medical, Doctors, Clinics” → “Healthcare” “Governm ... - New News for dnswl.org
News for dnswl.org website and data used to be located at http://www.dnswl.org/news. To make matters easier to edit, we now switched to a blog-based system for these news. The blog is available at http://news.dnswl.org/, including RSS/Atom feeds for consumption in your favourite newsreader. - dnswl.org data and SpamAssassin 3.2.0
SpamAssassin version 3.2.0 includes rules to query dnswl.org. Unfortunately, the rules as distributed are not complete — while the rules to distinguish low, medium and high scores are present, the actual lookup is missing. Add the following to your local.cf (or equivalent) to enable the rules: header __RCVD_IN_DNSWL eval:check_rbl('dnswl-firsttrusted', 'list.dnswl.org.') See the How to use section if you use an earlier version of SpamAssassin and want to enable dnswl.org lookups.
