3 pass 2 weak

Can mail be forged as this domain?

Yes on paper, but unlikely to land

DMARC is set to p=none, which only asks for reports, so nothing this domain publishes tells a receiver to reject a forged message. In practice a forgery will still be caught: a provider this size runs its own reputation and content filtering on top of what the domain publishes. That safety net is the provider's, not the domain's.

  • 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=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.

  • 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 89?

  1. Registered more than five years ago.
  2. Accepts mail through 1 MX host.
  3. SPF ends in -all, so mail from any other server is rejected.

What to publish to close the gaps

The records outlook.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. Move DMARC off p=none

    Name_dmarc.outlook.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.

  2. Switch MTA-STS to enforce

    Valuemode: enforce

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