Can mail be forged as this domain?

A forgery is sent to spam, not the inbox

DMARC is set to p=quarantine and enforced on every message, so a receiver that honours it does not reject a forgery outright but files it in spam rather than the inbox. Moving to p=reject would drop it entirely.

  • 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.

  • Pass

    DMARC p=quarantine

    Receivers are asked to send failing mail to spam rather than the inbox.

  • Weak

    MTA-STS testing

    A policy is published in testing mode. Failures are reported but delivery still goes ahead over an unverified connection.

  • Weak

    DNSSEC Not signed

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

  • Pass

    TLS-RPT Published

    Sending servers have an address to report failed TLS deliveries to.

Why it scores 50?

  1. Addresses here are forwarding aliases that hide the real mailbox, so one person can hold any number of identities on this domain.
  2. This domain hands out forwarding aliases that mask a real mailbox.

What to publish to close the gaps

The records slmails.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. Tighten SPF to -all

    Nameslmails.com
    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. Raise DMARC to p=reject

    Name_dmarc.slmails.com
    TypeTXT
    Valuev=DMARC1; p=reject; pct=100; rua=mailto:[email protected]

    Quarantine sends forgeries to spam, where people still find them. Reject stops delivery.

  3. Switch MTA-STS to enforce

    Valuemode: enforce

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

  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.
