SPF record Check

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. Use the SPF checker to validate the published SPF Record for a given domain. We strongly recommend to carefully test any updates the SPF records before applying them. We can also test a future change to the SPF Record in advance to ensure there are no complications during implementation

What is the SPF lookup for? With the SPF lookup you analyze the SPF record of a domain for errors, security risks and authorized IP addresses.

It also features a DNS lookup counter. To run an SPF check, enter the domain in question, and it will fetch the SPF record (if any) from the DNS Om SPF te implementeren dient u over een geldig SPF-record te beschikken.
