How does SPF record checker work?

An SPF checker validates a domain’s SPF record, which specifies authorized mail servers for sending emails on behalf of the domain. The SPF record checker retrieves the domain’s SPF record, parses its rules, gathers the sender’s IP address, evaluates it against the record, and determines the result as pass, fail, softfail, neutral, or permerror

This helps prevent email spoofing and phishing attacks by ensuring compliance with the SPF policy.
