# DMARC

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that builds on SPF and DKIM.

## How DMARC Works

DMARC specifies how receiving mail servers (such as Gmail, Yahoo, Apple Mail) should handle incoming emails claiming to be from your domain if they fail SPF or DKIM checks.

### Policies

* `p=none`: Monitor mode. Mailbox providers deliver messages as normal and send aggregate reports to your specified email.
* `p=quarantine`: Suspicious emails that fail authentication are routed to the recipient's Spam/Junk folder.
* `p=reject`: Highest enforcement. Emails failing authentication are completely blocked and rejected before reaching the inbox.

## Recommended Record

Add the following TXT record at `_dmarc.yourdomain.com`:

```
v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com; pct=100;
```
