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

1 pass 3 weak 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.

  • 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.

  • 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.

  • 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 67?

  1. No DMARC record, so receiving servers have no policy to apply to forged mail.
  2. Accepts mail through 1 MX host.
  3. Mail is handled by a mailbox provider we recognize.

What to publish to close the gaps

The records outlook.de 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

    Nameoutlook.de
    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. Publish a DMARC record

    Name_dmarc.outlook.de
    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.outlook.de
    TypeTXT
    Valuev=STSv1; id=<a version string you bump on every change>

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