Mailhardener is now self-learning
Today we are proud to introduce our biggest update yet. The December release of Mailhardener introduces a new domain overview page, which is made possible thanks to the introduction of our new self-learning algorithm.
New self-learning algorithm
Mailhardener is now self-learning. It analyses data from various sources such as DNS settings, DMARC reports, TLS reports, domain reputation and numerous other sources to give you the most accurate overview of the security status of your domain to date.
With the new algorithm Mailhardener can accurately distinguish senders, forwarders and fraudulent actors that are using your domain name.
The new domain overview page
With all these new insights that the algorithm can tell about a domain, we designed the new domain overview page. It shows you the complete security status of your domain.
We have designed a new safety rating for domains. The security rating is calculated using all the security aspects that we monitor. The rating gives you a quick insight into your domain's email security status.
Automatic service detection
Another new feature the algorithm makes possible is the automatic detecting of which email services your domain uses.
The new outgoing email overview shows you the email services used by your domain, together with the DMARC report results for the past month. Per service, we show you the percentage of emails that passed SPF and DKIM inspections, and the DMARC outcome (accepted, quarantined or rejected).
Inbound email monitoring
Last release we introduced hosted MTA-STS support. With it, we were one of the first email hardening platforms to embrace this new technology.
We have now taken this one step further and added active monitoring for your incoming email services. On the new overview page we now show the status if the incoming email services, if there are any TLS related issues that would prohibit secure delivery of email to your domain, you'll see it here.
Detection of email forwarders
You may have noticed before that there are often DMARC reports for email services that you did not use. These emails are often still accepted by the receiver, regardless of your security settings. That's because these senders are often forwarding email services, they are harmless but hard to distinguish from fraudulent senders. This is because the DMARC reports itself don't distinguish forwarders from regular senders.
But, with the new self-learning algorithm we can now reliably distinguish forwarders from senders.
By default, Mailhardener will now hide forwarders from the DMARC reports, and forwarders also do not count towards the sender statistics. This gives you a much more accurate insight on DMARC aligned emails from the services that you actually use.
Future additions
With the new self-learning algorithm we now have much more accurate insights into the security status of a domain.
This allows us to build exciting new features, such as automatic anomaly detection, configuration advice and live reporting.
Let us know what you think!
You can check out the new features right now by logging in to your account. If you don't have an account, you can view the demo or sign-up with your domain, it's free to try!
Lastly we want to thank everybody for the helpful feedback that we have received. This greatly helps us to improve our service. Please tell us what you think via @mailhardener on X, or send us an email.
