MX identifies the observed inbound mailbox or gateway. SPF includes identify services authorised to send for the domain. DMARC shows the published authentication policy. The dataset currently contains 2 populated signal groups for this page.
Observed deliverability context: based on the available observations, this page describes DNS configuration only. It does not represent a complete audit of qubes-os.org and does not prove that a particular message reaches the inbox or spam folder.
qubes-os.org uses Zoho Mail for inbound mail (detected from its primary MX record) as of July 25, 2026, per Live Direct Marketing's daily Tranco top-1M scan.
No — qubes-os.org publishes p=none, which only monitors and does not block spoofing (as of July 25, 2026).
Same daily dataset, three views: how its mailbox provider is trending, how strict DMARC is at its position in the list, and where its own policy sits among all DMARC publishers in the dataset.
The two ways an SPF record silently stops working. Counted from the published record; include chains are resolved one level deep, so the lookup count is a lower bound.
Adoption of the records that go beyond SPF and DMARC. Shown for the whole snapshot — per-domain detail lives on the security posture report.
The MX hostname resolved to its addresses, and those addresses resolved back. Missing or mismatched reverse DNS is one of the few DNS-visible causes of outright rejection.
mx.zoho.com has a PTR record matching its own zone.204.141.43.44 also hosts 6 other mail hosts — a shared server, so reputation is shared too.The same snapshot cut by zone, by list position and by how alive the published policies are.
