# SPF, DKIM, DMARC

> How OpenMail implements SPF, DKIM, and DMARC to authenticate your emails and maximize inbox delivery rates for outbound agent messages.

OpenMail handles SPF and DKIM for your sending domain. Configure your domain in the [Dashboard](https://console.openmail.sh/login) 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.
