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

To setup DKIM for your SpamTitan emails, please enable DKIM in SpamTitan by following these steps:
​System Setup -> Mail Relay -> DKIM.
