How to set up DMARC for DuoCircle in Valimail

Updated over a week ago

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

To begin signing your outbound email messages with DKIM open the Sender Domains & DKIM configuration page for your service, found under your account in the DuoCircle client area. DKIM signing is performed on a per-domain basis, so you must list on this page all domains which will send mail through your Outbound SMTP relay service. Once you have populated this list you may enable DKIM for specific domains by clicking the red "NO" button in the row of each domain.

This action will enable DKIM signing for that domain and also generate a new DKIM key if no previous key is already known to the system. The red "NO" button will turn to a green "YES" on success, and you will now see two options under the DKIM tools heading:

Click the magnifying glass button (left) will display the DKIM settings for this domain. To complete the process of configuring DKIM signing you will need to create a TXT record matching the provided values with your domain's DNS provider. DuoCircle immediately begins DKIM-signing your outbound mail from this domain, however recipients will not be able to verify the signature until this TXT record has been added and propagated through the DNS system.

Important: If you manage DKIM for your domain in Valimail, you will need to add the TXT DKIM key on your domain's Configuration page in Valimail.
