SPF contains a malformed macro
ATTENTIONWhat it means
The macro in the offending value does not parse. Depending on the receiver it expands to something unintended or errors the record out.
How to fix it
Correct or remove the offending value. Macros are rarely needed outside large hosting platforms.
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 7. Every finding on this site cites the specification behind it so you can check the work rather than take our word for it.
