SPF(supported)
DKIM(recommended)
This article covers the SPF and DKIM authentication processes for Gandimail and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.
Configuring DKIM authentication for your Gandimail emails
You can activate DKIM in your account by following these steps:
After logging in, click “Domain in the left navigation menu.
Click on the domain name attached to the email you want to manage.
Click on the “Email” tab.
Next to “Settings & Security” click “Edit.”
Switch the toggle next to “DKIM Signature.”
Click “Update.”
If your domain and email are hosted by Gandi, but you do not use Gandi LiveDNS (usually if you use a nameserver that is not provided by Gandi) then you can still activate this option manually by adding the following records to your domain.
gm1._domainkey 10800 IN CNAME gm1.gandimail.net.
gm2._domainkey 10800 IN CNAME gm2.gandimail.net.
gm3._domainkey 10800 IN CNAME gm3.gandimail.net.
All three CNAME records are needed in case of key rollover.
NOTE: If you manage you domain in Valimail, you will need to add the 3 CNAME DKIM keys on your domain's configuration page in the Valimail platform.

Configuring SPF authentication for your Gandimail emails
Once you establish that Gandimail is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
