Whether the domain that passed SPF or DKIM matches the From: domain. Relaxed allows subdomains; strict requires an exact match.

DMARC Generator

A DMARC record is a TXT record at _dmarc.<domain> whose tags set the policy, alignment, and report addresses. This generator builds the exact value to publish and explains each choice in plain English.

When to use this: You are publishing DMARC for the first time or moving from p=none to quarantine or reject. Command prefix dmarc-generator:

Policy (p)Subdomain policy (sp)Percentage (pct): 100%Failure options (fo)Aggregate reports (rua)Forensic reports (ruf)DKIM alignment (adkim)SPF alignment (aspf)

v=DMARC1; p=none

• Monitoring only: failing mail is still delivered. Start here, then tighten.
• No rua address set — you will not receive feedback reports.
• DKIM alignment is relaxed; SPF alignment is relaxed.

Publish as a TXT record at _dmarc.yourdomain.com.
