Can mail be forged as this domain?

No, a forgery is rejected

DMARC is set to p=reject and enforced on every message, so a receiver that honours it throws away any mail that fails alignment for this domain.

  • Pass

    SPF -all

    The record ends in -all, so a receiver is told to treat mail from any host outside the list as a forgery.

  • Pass

    DMARC p=reject

    Receivers are asked to reject any message that fails DMARC. This is the strongest published setting.

  • Weak

    MTA-STS testing

    A policy is published in testing mode. Failures are reported but delivery still goes ahead over an unverified connection.

  • Weak

    DNSSEC Not signed

    The zone is not signed. A resolver has no cryptographic way to tell a real answer from a forged one.

  • Pass

    TLS-RPT Published

    Sending servers have an address to report failed TLS deliveries to.

Why it scores 100?

  1. Registered more than five years ago.

What to publish to close the gaps

The records facebook.com is missing, in the order they are worth doing. Owner names are written out in full, so they work whether your DNS panel wants a full name or a relative one.

  1. Switch MTA-STS to enforce

    Valuemode: enforce

    Change mode in https://mta-sts.facebook.com/.well-known/mta-sts.txt and bump the id in the TXT record. Testing mode reports failures but still delivers.

  2. Sign the zone with DNSSEC

    Turn DNSSEC on with your DNS provider, then publish the DS record it hands you at your registrar. Every record above is only as trustworthy as the answer that carries it, and signing the zone is what makes the answers verifiable.
