Description:
Verifies that SPF policies are published for all domains.
Why:
An adversary may modify the "FROM" field of an email such that it appears to be a legitimate email sent by an agency, facilitating phishing attacks. Publishing an SPF policy for each agency domain mitigates forged "FROM" fields by providing a means for recipients to detect emails spoofed in this way. SPF is required for FCEB departments and agencies by Binding Operational Directive (BOD) 18-01, "Enhance Email and Web Security".
