System Documentation
What problem does it solve?
It reduces email spoofing and phishing risk by helping you assess whether a sender domain is properly authenticated and whether Mimecast flags it as trustworthy.
Core Features & Use Cases
- SPF, DKIM, and DMARC audit: Checks DNS TXT records for SPF and DMARC and evaluates DKIM posture (including handling unknown selectors).
- Mimecast sender reputation review: Uses the connected Mimecast email-security connector to pull sender reputation and recent delivery history for the domain.
- Action-ready recommendations: Produces a risk rating and a recommended allow/block approach based on authentication alignment and reputation.
Quick Start
Run /sender-policy-check acme.com to generate a structured sender authentication and Mimecast reputation report for that domain.
