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

Contact Simpro Support to get a DKIM key generated for your Simpro Premium build. Follow up with Simpro Support once the key has been added to your DNS so that it can be validated.

You can also find the instructions on how to set up DKIM and SPF for SimPRO, here.
