Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

if [ ! -x "$(command -v rpm)" ]; then echo "FAIL"; exit 1; fi
if [ ! -n "$(rpm -qa | grep -w postfix)" ]; then echo "FAIL"; exit 1; fi
echo "PASS"; exit 0

Remediation
