Explanation

Bounce Verification is enabled by default on the Cisco Email Security Appliance (ESA) C-Series because it provides immediate protection against bounce attacks without requiring administrator intervention - Cisco ships it in an active state to ensure out-of-box resilience against forged bounce messages flooding the appliance.

Local Reporting (A) must be explicitly configured and enabled; by default, reporting data may be sent to a Security Management Appliance (SMA) or simply not activated locally. Local Message Tracking (B) is disabled by default and requires the administrator to turn it on under Security Services, as it consumes local disk resources. Encryption (C) requires both a feature license and manual configuration of an encryption profile before any messages can be encrypted - nothing ships ready-to-use.

Memory tip: Think "B for Bounced by Default" - Bounce Verification is the one feature Cisco pre-enables because stopping forged bounces is a baseline security need, whereas reporting, tracking, and encryption all require deliberate setup choices.
