I use much the same config.  Exim can be running but not necessarily ready to
run the queues at the same time as you connect, so you have ifplugd, or
whereami, or some other network-aware program, do an explicit queue run at

Meanwhile, exim doesn't need to know if it's offline - you send it mail, it
tries to forward it, and if it can't it puts it in the queue for retry.
