[Bug][cyber] Auditing own M365 tenant for missing anti-spoof mail-flow rule after registrar defederation false (req_011CcPEezHx9SZ9QBaEPGSMg)

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): cloud-iam

Why this is a false positive

The block is a false positive: the work is authorized, in-scope administration of the operator's own cloud identity tenant — auditing mail-flow and authentication (SPF/DMARC) configuration to diagnose and close an email-spoofing gap on a domain and mailbox the operator controls. The flagged terms ("spoof," "malicious," reading message headers) describe standard defensive incident response and anti-spoofing hardening, not offensive activity against a third party. No exploit, intrusion, or unauthorized access is involved — only legitimate inspection of owned infrastructure using credentialed, first-party API access.
