SPF Checker
SPF Record Checker - Validate SPF Records
Check and validate SPF (Sender Policy Framework) records for any domain. Verify email authentication configuration.
How It Works
This tool queries the TXT records of a domain and looks for SPF records (starting with "v=spf1"). It then parses and validates the SPF syntax, checks for common issues like too many DNS lookups (max 10), missing "all" mechanism, and deprecated mechanisms.
Understanding Results
The results show the raw SPF record, parsed mechanisms (include, ip4, ip6, a, mx, etc.), and any validation warnings or errors. A valid SPF record should have proper syntax and end with an "all" mechanism.
