3 pass 2 weak

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 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.

  • 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.

What to publish to close the gaps

The records mailinator.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 an MTA-STS policy

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

    Serve the policy body at https://mta-sts.mailinator.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.

  2. Publish a TLS reporting address

    Name_smtp._tls.mailinator.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.
