Mailgoose is an open-source, white-label tool by CERT PL that helps organizations verify SPF, DMARC, and DKIM configurations to reduce email spoofing risk. It offers two checks—sending a test email for full SPF/DMARC/DKIM validation or a domain-only lookup for SPF/DMARC—and is already adopted by Lithuania’s NCSC, with the source code available on GitHub for other CSIRTs to deploy.
