fbi.gov - Email Domain Verification & Deliverability Report

The domain fbi.gov belongs to the Federal Bureau of Investigation (FBI), the principal federal law enforcement and domestic intelligence agency of the United States. Headquartered at the J. Edgar Hoover Building in Washington, D.C., the FBI investigates federal crimes, counterterrorism, cybercrime, and counterintelligence matters across all 50 states and internationally.

As a federal .gov domain, fbi.gov complies with CISA Binding Operational Directive 18-01, mandating DMARC, SPF, and DKIM. The FBI is one of the most impersonated government agencies in the world, with phishing campaigns frequently exploiting the FBI's name to intimidate victims, distribute malware, or conduct fraud schemes.

FBI mail servers operate under highly restrictive SMTP configurations. The infrastructure does not function in catch-all mode, and recipient validation is strictly enforced at the connection level. As a premier law enforcement agency, the FBI employs the most aggressive rate limiting, greylisting, and advanced threat detection systems.

Delivering email to fbi.gov is subject to the strictest filtering in federal law enforcement. FBI email gateways employ advanced content analysis, malware sandboxing, and multi-factor sender verification. Full SPF, DKIM, and DMARC compliance with an impeccable sender reputation is required for any delivery attempt to FBI addresses.
