OpenMail handles SPF and DKIM for your sending domain. Configure your domain in the Dashboard and add the provided DNS records.

​
SPF

SPF (Sender Policy Framework) authorizes our servers to send on behalf of your domain. Add the TXT record we provide.

​
DKIM

DKIM (DomainKeys Identified Mail) signs outgoing messages. Add the CNAME records we provide.

​
DMARC

DMARC (Domain-based Message Authentication) tells receivers what to do with messages that fail SPF/DKIM. We recommend a policy record once SPF and DKIM are in place.
