SPF(supported) (dedicated subdomain)
DKIM(recommended)



This article covers the SPF and DKIM authentication processes for Rejoiner and how they are managed in Valimail Enforce. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.
