SPF Validator
Basic validation of SPF syntax and common pitfalls.
The SPF Validator fetches the SPF TXT record for your domain and checks:
- That it starts with
v=spf1 - Whether multiple SPF records exist (which is invalid)
- Structure of mechanisms (ip4, include, all, etc.)
- Position and use of the
allmechanism
It does not perform full DNS-walk or recursion validation, but gives a quick indication if your record is sane.
