**Official exam objective:**

> Given a scenario, solution issues regarding Reply Mail Management.

## What the exam expects

- Diagnose why a reply was deleted, unsubscribed, forwarded, throttled or misrouted from the RMM settings and the reply's content.
- Plan the DNS work RMM needs for a delegated or a self-hosted domain.
- Choose between account-level RMM, a sender profile's custom settings, direct forwards and Enterprise RMM for a sending requirement.
- List the elements a triggered-send auto reply needs, and explain where its From address and name come from.
- Key terms: **Reply Mail Management (RMM)** (the SAP feature that processes and forwards replies); **reply subdomain** (the subdomain that points replies at Engagement's reply rules); **routing address** (the mailbox that receives replies no rule identifies); **Enterprise RMM** (a separate feature that applies rule collections per sender profile).
