A relevant domain name for a domain in the set of domains is accessed through a domain comma-separated value (CSV) file. An invalid domain name not adhering to CSV format specifications is identified. Any domains without a valid domain name system (DNS) text record are determined. Domains having insufficient SPF configuration mechanisms are determined. Domains having insufficient SPF configuration qualifiers are determined. Domains having insufficient SPF configuration modifiers are determined. A determination is made whether the domain is valid and the SPF configuration is valid based on a domain name, the DNS text record, the mechanisms of the SPF configuration, the qualifiers of the SPF configuration, and the modifiers of the SPF configuration. A report of a set of SPF configurations corresponding to a set of domains is provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sender policy framework (SPF) configuration validator and security examinator","description":"Systems and methods include a computer-implemented method for validating domains and Sender Policy Framework (SPF) configurations.
