What is the SPF lookup for?

With the SPF lookup you analyze the SPF record of a domain for errors, security risks and authorized IP addresses. Optionally, you can specify an IP address to check if it is authorized to send e-mail on behalf of the domain. The SPF lookup analyzes registered TXT records in real time. If you want to specify an SPF record manually, use the SPF Analyzer.

No explicit IPv6 addresses in the SPF record have been authorised to send

How is the sender informed?

The exp mechanism acts as a return to the sender if the IP address was not authorized to send and notify them. None was found.
