What is DKIM?

DKIM is a standard for ensuring that emails sent come from a valid sender and is especially useful when emails are sent via a third party, such as Lega Online, EduAdmin, or EditNews.

Example: If Gmail cannot verify that the sender is valid, it will display an extra "via ..." text after the sender so that the recipient knows that the email is not coming directly from the sender listed in the email.

This may cause concern for recipients, especially if the email contains sensitive information.

How do we activate DKIM?

Create a new key in your domain as follows:

editnews._domainkey.<your domain>  CNAME  dkim.editnews.com

Example: If the domain is multinet.se, the following key should be created:

editnews._domainkey.multinet.se  CNAME  dkim.editnews.com

Once the CNAME has been configured by your IT team, you can click the update button under Company Settings -> Manage -> Company Information (requires administrator rights).

The signing ensures that Gmail, and others, can verify that the emails are sent with permission from

the owner of the domain, and therefore no extra "via ..." information is needed.

How do I remove DKIM if we no longer use your services?

Remove the record in your domain's DNS server.

Then, receiving servers will no longer be able to verify the key.

Technical details (for the curious)

DKIM works by having our server, when sending emails with your domain as the sender, create a signature that is included in the email.

This signature is named editnews.

The recipient's server looks for the key named editnews under "_domainkey" in the sender's domain, i.e., your domain.

If it finds a CNAME (as specified above), it will proceed to our server and retrieve the actual key to verify the signature.

Since this process occurs through your domain, the recipient knows that you have approved us to send emails with your domain as the sender.
