DKIM is one of the most important authentication mechanism used nowadays to protect your domain's reputation on the Internet. Main email providers are very restrictive against domains not using it.
The principle is easy: every email you send is automatically signed by your server using a private key and receiving servers can check the validity of this signature using a public key available within the DNS zone of your domain.
Thus if the verification fails, it is easier to detect phishing attacks for example.
Modoboa won't sign messages but OpenDKIM will. This software is designed for this purpose and integrates well with Postfix. The installer will be updated to integrate a working setup which will communicate with Modoboa.
What Modoboa will provide is the ability to generate signing key pairs per domain in a easy way:
And a quick way to display the public key to let you configure your DNS zone:
If you need/want/like this feature, it is time to sponsor it ;-)
once again thank you for your support. I'm glad to announce you that the installer now deploys a functional OpenDKIM setup! You will find more detail about the implementation on Github.
As a bonus, I've started to work on a little rspamd plugin which makes use of the generated DKIM keys. I'll add some documentation soon.
the first part of this feature (ability to generate DKIM keys from Modoboa) has been released with the 1.10.0 version. You will find some details in the related Github issue.
We hope you will enjoy it and once again, thank you for your support!
