Welcome to DKIM Reputation!

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!


    Message Face

    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.

    Anti-Spam: Technology For Your Server

    4348132501_d4ed580f39_bOne of the problems that people these days are always troubled with is spam. Arriving in the amounts of thousands sometimes, spam is not only exasperating, but also time-consuming. It almost seems pointless for all companies who intend to promote themselves, since no one ever pays attention to spam. But it does not change the fact that you never want it clogging the drains of the plumbing in your server. Thus, it is necessary for server hosts to employ effective spam resistant technologies to ensure that the smooth functioning of their accounts.

    Today, there are numerous spam filter packages of varying capacities and strengths, with each priced at their own range. As technology has evolved, so has the way of fighting spam. The traditional methods are now obsolete and archaic, and people have now turned to external anti-spam methods.

    When looking to protect your dedicated server from spam, it is best to go for an anti-spam cluster. Unlike traditional anti-spam methods, an external anti-spam cluster is not a part of the email system and can thus function more effectively than them.


    • An anti-spam cluster can filter many more messages than a traditional filter can. Their filtering capacities are advanced and lie in millions.
    • All viruses, malware, and other threats detected are quickly implemented against, thus protecting the system.
    • Anti-spam methods will protect your domain against malware, viruses, phishing software and other threats that might harm your system through the internet.
    • Most anti-spam software are also updated and programmed to recognize new spam forms instantly and will thus save you from the hassle of having to update every time you hear news of new forms of spam going around.

    Types of Spam Filters:

    Depending on the strength and requirements, there are different types of spam filters for various servers. For example, general websites that have low to medium traffic and not much work except transfer of data might not require strong spam filters. An economy filter will be ample for them.

    However, advanced filters may be needed for websites that see heavy traffic on a daily basis and require running on their interface large, memory consuming applications. These need RAM that is easily upgradable and expandable and storage that is enough for running apps without slowing down. Such spam filters may cost more than ordinary ones that only filter simple emails.

    What to do when looking for spam filters?

    When looking for efficient spam filters that will protect your PC from threats and viruses make sure that you first look at all features of the software. It is best if the anti-spam control has additional features like report generation, white labeling and queuing up emails. Although these features may not always be necessary, it does help to extra hands on deck.

    Additionally, a beneficial tip for you will be to look for spam filters that offer per domain licensing instead of the usual per use licensing and cost, thus making hosting website less costly.

    Spam Assassin For cPanel

    People that use InMotion Hosting for their website have access to the free tool of Spam Assassin.

Spam Assassin is different from other email filtering tools; this software catches the spam once it hits your server- meaning that it gets rid of the email before it hits your inbox.

    Spam Assassin level of security is number one to ten, each level tells the software the level of spam security your dedicated server is working on. When you enable the software, it is automatically set on five. This point system uses hits to filter the spam. Spam Assassin finds characteristics in emails that are associated with spam and gives the email a point value between one and ten. This means if the email hits more points then you have set for the software then it will be sent to your spam folder.

    The lower you have it set, the more messages that will be flagged as spam. So this means if you have it set on one, then if it just has one characteristic of spam email, it will get flagged. If you have it set on ten then if it has less than ten characteristics then it will end up in you inbox and not spam. This is why the default setting is five on the software. You should try out all the setting until you find one that works the best for you.

It also has a feature where you can blacklist emails that you don’t want to receive, in addition to a white list that will keep important emails out of your spam folder.

    To make sure that Spam Assassin is working at its maxim capacity you also want to set up Filter/Message through your email provider as well. Setting up these filters will keep junk mail from entering your inbox. The emails that are spam will begin with ***SPAM*** which will be sent to your junk mail folder. This step will advance the way Spam Assassin works in your email.

    Spam Assassin will keep you inbox from receiving any unwanted emails and keep your important ones from making it to your junk folder.
