What is the SPF analyzer for?

With the SPF Analyzer you analyze a manually submitted 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-mails on behalf of the domain. If you want to analyze an SPF record in real time from the DNS, use the SPF lookup.
