Postfix mail server

v0.1.6

Queue inspection, config dump, log tailing, plus narrow operator actions (flush, requeue, delete-by-queue-id). These mutators are high- or critical-risk; the reversible hold/release pause is medium. All are audited. Postfix uid must own the runner OR runner must be in the postdrop group.

Install

emisar pack install validates the pack and verifies its content hash before copying it into /etc/emisar/packs. The --hash below pins the install to the exact bytes on this page — a tampered copy is rejected. After install, reload the runner; it re-reads the catalog and advertises every action.

content hash: sha256:ea996fab8a00fe8fb5cd8147b4e3aa3b4a35bb9e233e5531dec7af8a578393b1

on the runner host

sudo emisar pack install postfix \
  --hash sha256:ea996fab8a00fe8fb5cd8147b4e3aa3b4a35bb9e233e5531dec7af8a578393b1 \
  --dest /etc/emisar/packs

# Reload so the runner re-reads the catalog:
sudo systemctl reload emisar
