How to set up DMARC for EmailLabs in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for EmailLabs 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 EmailLabs emails

When authorizing a From domain, you can use the Default Key option.

A domain with this status signs messages sent from authorized Email addresses (replacing the signature with the domain’s signature).

Sender Authorization Form in EmailLabs panel

Domain authorization is done by placing a DKIM record in DNS. The domain authorization form (Sender Authorization tab) contains several fields. Below is an explanation of each parameter.

  • domain from: the domain used in the from address, from which messages will be sent and which is to be authorized, e.g. … or … Note: we recommend the use of a subdomain, as a CNAME entry must be placed in the DNS records to authorize the domain;

  • auxiliary description: an additional designation/description of your domains in the EmailLabs panel. This description is administrative information visible only in the EmailLabs panel.

  • selector: in this field put the selector you want to use to mark DKIM in your domain, e.g. “plpl”. The minimum length of the selector must contain 3-4 characters; both numbers and letters can be used. The selector is the label that allows the DKIM key to be searched in DNS records.

Default key (for email addresses) – if you want to sign your authorized EMAIL ADDRESSES with the DKIM key associated with a specific domain, add it to the Domain Authorization tab and mark it as default.


After completing the form, the generated CNAME type record must be added to the DNS of the domain you entered during authorization. The entry will be available after saving the form.

Once you establish that EmailLabs is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
