1 pass 4 weak

Can mail be forged as this domain?

Yes, a forgery is delivered

DMARC is set to p=none, which only asks for reports, 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.

  • Weak

    SPF ~all

    The record ends in ~all. Mail from a host outside the list is only marked, not rejected, so it usually still arrives.

  • Weak

    DMARC p=none

    A DMARC record is published, but p=none only asks for reports. Receivers are told to deliver failing mail anyway, so this stops no forgery.

    A checker that reports "DMARC found" here is telling you nothing useful.

  • 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 89?

  1. Registered more than five years ago.
  2. Accepts mail through 2 MX hosts.
  3. Mail is handled by a mailbox provider we recognize.

What to publish to close the gaps

The records fast-email.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. Tighten SPF to -all

    Namefast-email.com
    TypeTXT
    Valuev=spf1 <your existing mechanisms> -all

    Keep the mechanisms you already have and change the final qualifier. Anything softer leaves the forgery path open.

  2. Move DMARC off p=none

    Name_dmarc.fast-email.com
    TypeTXT
    Valuev=DMARC1; p=quarantine; pct=100; rua=mailto:[email protected]

    p=none blocks nothing. Once your reports show every legitimate sender passing, raise the policy to quarantine and then to reject.

  3. Switch MTA-STS to enforce

    Valuemode: enforce

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

  4. 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.
