Review mail flow, authentication, transport rules, security, and operational readiness.
Mail flow
Review connectors, accepted domains, centralized transport, third-party gateways, and message trace patterns.
Authentication
Validate SPF, DKIM, DMARC, modern authentication, and legacy protocol exposure.
Transport rules
Identify outdated, duplicated, overly broad, or conflicting mail flow rules.
Mailbox protection
Review anti-phishing, impersonation protection, Safe Links, Safe Attachments, and high-risk users.
Operations
Confirm monitoring, escalation, documentation, and ownership for incidents and changes.
