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 SPF record could be determined for the domain "mobile.l.google.com".
No SPF record could be determined for the domain "new-go.xero.com.edgekey.net".
