SPF(supported)
DKIM(recommended)

This article covers the SPF and DKIM authentication processes for 20i (ex Stackmail) 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 20i emails

  • Head to Manage Hosting and 'Manage' the package you want to add a DKIM record.

  • Select the DomainKeys icon.

Firstly, we'll explain how to add a simple DKIM record to your DNS.

  • Ensure you’ve selected the domain you want to add the DKIM record-to.

  • Add a Selector. This can be any value or name you like. It’s simply a field to identify the DKIM record. Then select Add Signature.

DKIM signatures
  • If your nameservers are with 20i, we’ll automatically add the correct TXT record for you.

The signature will be added immediately to emails sent from the mailboxes under the domain selected. We will have automatically added a DNS record to Manage DNS. You may wish to wait for this to resolve for DKIM to be effective.

From here you’re all done: your emails will use DKIM as a method to authenticate email.
