MAIL DNS DIFF

LIVE DNS / DATED EVIDENCE / FREE

What does your
SPF say now?

Read the actual SPF record, without mistaking unrelated TXT verification tokens for mail policy.

No account. No inbox access. No email is sent to the domain.

A record lookup, with a memory

We query TXT at the exact domain you enter and keep only records beginning with v=spf1. Split quoted DNS strings are joined before comparison. Unrelated TXT tokens are discarded.

Spot a lost sender after a migration

The useful question is often “did that include disappear?” A saved baseline makes removals and additions visible in the shared receipt.

This is not a recursive SPF validator

Includes, redirects, macros and the ten-lookup limit need additional evaluation. We show the published record and flag multiple SPF records; we do not claim a message will pass SPF.
