What is DKIM?
DKIM is a standard used to validate that an email is sent from a valid sender.
This is primarily used when email are sent through a third party, e.g. through DealManager.
Example: In case Gmail can't validate the sender it will show an extra "via ..." text after the senders address, to show the receiver that the email wasn't sent directly from the sender of the email.
This could make the receiver worried, especially if the email contains sensitive information.
How do I activate DKIM?
Create a CNAME record in the following format:
editnews._domainkey.<your domain> CNAME dkim.editnews.com
E.g.: If your domain is multinet.se you should create the following key:
editnews._domainkey.multinet.se CNAME dkim.editnews.com
Please contact us at MultiNet when you've created the CNAME. We'll confirm that it looks OK, then we'll activate the signature on your future emails sent through EduAdmin.
Note! The DKIM key used by EduAdmin is currently handled by our service EditNews.
Signing the emails will make Gmail, and others, able to verify that the emails are sent with permission by the owner of the domain, and this will result in the "via ..." text not appearing in you receivers inbox.
How do I remove the DKIM-key in case I stop using your services?
You only need to remove the CNAME from your DNS server.
This will result in the receiving email server not being able to verify the key.
