What linux0.net publishes in DNS to stop other people sending mail in its name, read record by record.

1 pass 1 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.

  • 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.

  • Fail

    DMARC No record

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

Why it scores 0?

  1. Mailboxes on this domain are throwaway, so no identity stands behind them.
  2. Registered in the last 90 days.
  3. No DMARC record, so receiving servers have no policy to apply to forged mail.

What to publish to close the gaps

The records linux0.net 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 a DMARC record

    Name_dmarc.linux0.net
    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.

  2. Publish an MTA-STS policy

    Name_mta-sts.linux0.net
    TypeTXT
    Valuev=STSv1; id=<a version string you bump on every change>

    Serve the policy body at https://mta-sts.linux0.net/.well-known/mta-sts.txt, start it in testing mode, then switch it to enforce so senders refuse to deliver over an unverified connection.

  3. Publish a TLS reporting address

    Name_smtp._tls.linux0.net
    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.

  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.
