The DKIM Reputation Project is closing down soon
After 6 years in operation the DKIM Reputation Project closes down its service at the end of April 2014. Since 2008 commercial anti-spam services adapted mostly the white-listing on behalf of domain name identification. In general the IP-based filtering is still dominating (let's see how things work out for IPv6 blacklisting) and a more intense need of domain-based filtering is out of sight. Therefore the close-down is consequent.
In the future a more user-account oriented instead of domain focused authentication - that maintains sender anonymity - should be created. Domains with a large number of users comprising worst to best sender behaviour make it impossible to strictly white- or blacklist by domain names only. The DKIM Reputation Project mastered this by a derived sender address reputation but we're sure there will be less complex solutions available in the future.
The DKIM Reputation Project's aim is to improve spam filtering based on DKIM signed emails. Therefore we provide the following free and open services:
- DKIM Reputation database, provided as a DNS reputation list
- DKIM signature verification and monitoring
- DKIM Reputation query
We also propagate the spread of authenticated email with the Sender Authentication Initiative!
As a practical application for email sender authentication we introduced a project called 'Message Faces' in the past for a better visual recognition of the people sending email to you. In our opinion such user-centric applications should favor the adaption of sender authentication. The project was terminated because of a lack of funding but may be revived in a new context.
DKIM Reputation query
Here you can check your own DKIM Reputation. All you need is to enter your email address or your domainname. In case that your email is signed by another domain, enter both.
Example:
Email: good@example.com Signingparty: example.com (best reputation)
Email: bad@example.com Signingparty: example.com (worst reputation)
Yes, I support the the spreading of email sender authentication to
- increase the probability of the delivery of emails of my known and appreciated senders
- increase trustability in email communication
- less Spam in my Inbox
DKIM Reputation database / DNS blocklist
In the DKIM Reputation database we collect identities of particularly spammers that are sending DKIM valid mails to spam traps we are processing. This data is provided as a DNS blacklist, which is accessible to anybody and can be used as one more spam filter criteria.
Our philosophy of processing and analyse our spamtraps is described on the mission page. But we support you also in how to use the DKIM Reputation Blacklist with ready built SpamAssassin plugins as well as with information on how to build your own client.
DKIM signature verification and monitoring
As we want to spread the DKIM standard we provide a free DKIM signature check: our service will check your DKIM signatures daily and will notify you, if your signature is invalid. Just register!
Furthermore we are developing a notification service, which will send you an email, when your maildomain is listed on our blacklist.
