3 pass 2 weak

Can mail be forged as this domain?

Yes, a forgery is delivered

DMARC is not enforced on the whole mail stream, so a receiver that honours what this domain publishes is not told to reject a message with it in the From header, and delivers it.

  • 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.

  • Weak

    DMARC p=reject

    The policy is p=reject but it is not applied to every message, most often because pct is below 100.

  • Weak

    MTA-STS Not published

    No MTA-STS policy, so a sending server has nothing that tells it to insist on verified TLS for this domain.

  • Pass

    DNSSEC Signed

    The zone is signed, so the MX, SPF and DMARC answers above cannot be quietly rewritten in transit.

  • Pass

    TLS-RPT Published

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

Why it scores 83?

  1. Accepts mail through 1 MX host.
  2. SPF ends in -all, so mail from any other server is rejected.
  3. A website answers on this domain.

What to publish to close the gaps

The records firemail.at 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. Apply DMARC to every message

    Name_dmarc.firemail.at
    TypeTXT
    Valuev=DMARC1; p=reject; pct=100;

    A pct below 100 samples the policy instead of applying it, so most forged mail is unaffected.

  2. Publish an MTA-STS policy

    Name_mta-sts.firemail.at
    TypeTXT
    Valuev=STSv1; id=<a version string you bump on every change>

    Serve the policy body at https://mta-sts.firemail.at/.well-known/mta-sts.txt, start it in testing mode, then switch it to enforce so senders refuse to deliver over an unverified connection.
