Frequently Asked Questions
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a policy that tells receiving mail servers what to do when an email fails SPF or DKIM authentication. It also enables aggregate and forensic reporting.
What is the difference between p=none, p=quarantine, and p=reject?
p=none monitors without action; p=quarantine sends failing emails to spam; p=reject blocks failing emails outright. Start with none, review reports, then escalate to reject for full protection.
What are rua and ruf tags in DMARC?
rua specifies where to send aggregate reports (daily summaries of authentication results); ruf specifies where to send forensic reports (individual failure samples). Both are email addresses in URI format.
