This article covers the SPF and DKIM authentication processes for APSIS 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.

APSIS' Delivery department provides you with everything you need in order to get DKIM ready.

In order to set up DKIM in APSIS for your domain, you will need to reach out to your APSIS Account Manager, who will be able to redirect you to their Delivery professionals.

APSIS issues and supports 2048bit TXT DKIM keys.

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 Enforce
