SPF authorises the entire internet
CODE REDWhat it means
The record for example.com ends in the offending value, which tells receivers that any server on earth is allowed to send as you. SPF is published, but it protects nothing.
How to fix it
Replace the offending value with ~all while you confirm your senders, then -all once your reports are clean.
Check your own domain
This page describes the condition. To find out whether your domain has it, run the SPF test or the full checkup, which examines every record at once.
Understand it properly
This page covers one condition. For the whole picture, What is SPF, and the ten-lookup limit, or start at the Health Library.
Where this comes from
We judge this against RFC 7208 section 5.1. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.

Every fix on this site is yours to implement. If you would rather someone did it, I take this work directly.
