COPY --chmod makes /etc/logrotate.d/mail 0644 regardless of build context file modes (Windows tar sync). logrotate-loop preflight exits non-zero when logrotate would ignore the config. E2e covers mode, forced rotation, and a group-writable context build. Co-Authored-By: Composer 2.5 <noreply@cursor.com> Co-authored-by: Cursor <cursoragent@cursor.com>

; One-shot reload helper (spec 5.2, 7.2.12). The panel runs unprivileged and
|
|
; cannot run `postfix reload` itself, and it cannot signal the Postfix master
|
|
; directly: `postfix start-fg` forks a separate master process, so a signal to
|
|
; the supervised foreground process never reaches it (unlike OpenDKIM, which
|
|
; runs in the foreground as the supervised process itself). Instead the panel
|
|
; asks supervisord — over the group-accessible control socket — to run this
|
|
; program, which executes the canonical `postfix reload` as root. autostart is
|
|
; off (it only runs on demand) and a fast, clean exit is expected, so it never
|
