mailspoof

Security teams running email infrastructure audits need mailspoof to quickly inventory which of your domains can be spoofed through SPF/DMARC misconfigurations before attackers find them first. The command-line interface makes it easy to batch-scan hundreds of domains in minutes, catching gaps that manual record review misses. Skip this if you're looking for continuous monitoring or automated remediation; mailspoof is a one-time assessment tool, not a runtime defense system.
