Postfix mail server

v0.1.7

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 fetches this pack, re-validates it, and verifies its content hash against the --hash below — the exact bytes this page was rendered against, so a tampered copy is rejected — before copying it into the runner's packs dir. The command reloads a running daemon itself; no manual restart.

    View source on GitHub
  • postfix.postsuper_requeue exec high

    postsuper -r <qid|ALL>

    Re-queue one message (or ALL deferred). The message is re-classified from the deferred queue back to active, retrying delivery.
