The bind-mounted quarantine dir is owned by the host decnet user; the logrelay process had no write access because the Dockerfile USER directive pre-applied before the entrypoint could fix permissions. Run entrypoint as root, chmod 0777 the quarantine dir, then exec the server under logrelay via su.
