3 weak 2 fail

Can mail be forged as this domain?

Yes, a forgery is delivered

no DMARC record is published, 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.

  • Fail

    SPF No record

    No SPF record is published, so receivers have no list of hosts allowed to send as this domain.

  • Fail

    DMARC No record

    No DMARC record is published, so receivers get no instruction and judge a forged message on SPF and DKIM alone.

  • 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.

  • Weak

    DNSSEC Not signed

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

  • Weak

    TLS-RPT Not published

    No reporting address, so failed TLS deliveries to this domain go unnoticed by its owner.

Why it scores 0?

  1. Mailboxes on this domain are throwaway, so no identity stands behind them.
  2. No DMARC record, so receiving servers have no policy to apply to forged mail.
  3. No SPF record, so anyone can send as this domain.

What to publish to close the gaps

The records vietcap.sbs 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. Publish an SPF record

    Namevietcap.sbs
    TypeTXT
    Valuev=spf1 include:<your mail platform> -all

    List every platform that sends on your behalf, then end the record in -all so everything else fails.

  2. Publish a DMARC record

    Name_dmarc.vietcap.sbs
    TypeTXT
    Valuev=DMARC1; p=none; rua=mailto:[email protected]; fo=1

    Start at p=none with a reporting address, read the reports for a few weeks to find the senders you forgot, then move the policy up.

  3. Publish an MTA-STS policy

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

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

  4. Publish a TLS reporting address

    Name_smtp._tls.vietcap.sbs
    TypeTXT
    Valuev=TLSRPTv1; rua=mailto:[email protected]

    Without it, a sending server that could not negotiate TLS with your mail hosts has nowhere to tell you.

  5. 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.
