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

Configuring DKIM authentication for your AuthSMTP emails
To enable DKIM on your domain names please login to the control panel and go to Advanced Config -> DKIM Signing.
AuthSMT issues a unique TXT DKIM key for each domain name so your DKIM reputation cannot be affected by other senders.
The DKIM key uses a AuthSMTP specific 'selector' and the signing will only apply to messages sent via your AuthSMTP account.
You can also find the instructions on how to set up DKIM and SPF for AuthSMTP, here.
