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.

  • 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=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.

  • 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.

What to publish to close the gaps

The records kolabnow.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. Raise DMARC to p=reject

    Name_dmarc.kolabnow.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.

  2. Switch MTA-STS to enforce

    Valuemode: enforce

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