LiveSource: DNS · public resolvers 1.1.1.1, 8.8.8.8Observed:
The tool reads the MX records of the domain and lists each mail host with its preference value. Where the hostnames match a well-known provider pattern it names the likely provider. It then fetches the SPF policy from the TXT records of the domain and the DMARC policy from _dmarc under the domain, parses both and reports findings.
Everything here is read from public DNS. The tool does not connect to your mail server, send test messages or look inside any mailbox.
What this service recorded for this name on earlier checks. A check happens only when someone opens a report or calls the API: nothing is scheduled, so gaps between checks are normal.
37 checks since Sep 25, 2026, the latest on Oct 11, 2026.
No change in the recorded values across 37 checks.
The history is kept for the domain name only; nothing about who looked it up is stored. Entries not seen again for 400 days are deleted. Changing A, AAAA and hosting values are normal for sites behind load balancers or content delivery networks.
Fixed points of reference, not rankings. Each line says what the value is compared with and where it came from.
