DMARC reports, a tool to protect your domain
DMARC authenticates emails, combats phishing, protects domains and enhances security by strengthening SPF and DKIM. It looks complicated, but it isn't.
DIAGRAM · AN EMAIL USING YOUR DOMAIN
Domain-based Message Authentication, Reporting & ConformanceDMARC + EMAIL GUARDIAN
Analyse and improve email security
DMARC reports together with Email Guardian allow you to:
- Verify DKIM signature checking (relaxed or strict)
- Check SPF policies (relaxed or strict)
- Verify DMARC policies (none, quarantine or reject)
Which translates into better visibility of email authentication, secure delivery to your recipients and identification of spoofing and unauthorised use.

EVERYTHING YOU CAN DO THANKS TO DMARC
Iberlayer invites you to discover it
Anti-spoofing
Real protection comes from SPF and DKIM, which require DMARC to be enforced firmly.
SPF enforcement
Thanks to DMARC you can tell third parties what to do when an SPF check fails.
SPF for subdomains
Everyone worries about their domains, but protecting subdomains (even non-existent ones) is just as important.
SPF alignment
SPF generally applies to the protocol From (Envelope-From), not the header From. With DMARC we can apply it to the latter too.
DKIM enforcement
If an email has no DKIM signature we cannot know whether DKIM is not used or the email is spoofed. DMARC answers this question.
DKIM alignment
aDKIM ensures the signing domain matches the sender domain (From: header), validating the authenticity of the message.
Reports by email
Via DMARC you can request reports of the emails that third parties detect, valid or not, using your domains in the From:.

HOW DOES IT WORK?
The DMARC report cycle
You publish the policy, receivers enforce it, Iberlayer turns their reports into useful information and helps you tighten it. Every turn of the cycle closes one more door to spoofing.
Legitimate mail signed with DKIM and sent from SPF-authorised IPs. Your DMARC record tells receivers what to do with everything else.
Gmail, Microsoft 365, Yahoo and any server enforcing DMARC verify SPF, DKIM and their alignment with the From: of every message using your domain.
Every receiver sends aggregate (RUA) and forensic (RUF) reports to the address Iberlayer manages for you. They are never shared with third parties.
Iberlayer processes the reports, detects spoofing and misuse, and helps you harden SPF, DKIM and DMARC up to the strictest possible policy.
