SPF Check & SPF Lookup - Sender Policy Framework (SPF) - MxToolBox
ABOUT SPF RECORD CHECK The SPF Record Check is a diagnostic tool that acts as a Sender Policy Framework (SPF) record lookup and SPF validator. This test will lookup an SPF record for the queried domain name, display the SPF Record (if found), and run a series of diagnostic tests (SPF Validation) against the record, highlighting any errors found with the record that could impact email delivery.

SPF Query Tool
Overview These tools are meant to help you deploy SPF records for your domain. They use an actual RFC 7208 compliant library (pyspf) for tests and will dynamically test for processing limit errors (no other testers I'm aware of do this). This site uses a caching DNS resolver, so for tests that use live DNS, results will be cached for the Time To Live of the DNS record. For most basic uses, these t
