If exim receives an email, it will attempt to deliver it to it's receipients
*immediately* - irrespective of any queue runner settings. The queue runner
settings only come into play if the email cannot be delivered a recipient,
and is then put on the queue for later delivery (for those recipients). For
a general purpose mail server this works very well.
If you are having problems with load, then look at the option
"deliver_load_max" (see exim documentation). This will prevent deliveries
if the machine load is above a certain value (the message will be queued for
later delivery until the load dies down).
Otherwise, use "queue_only" or "queue_only_load" to force messages to be
queued under specific circumstances (always, and based on load
respectively). Then the delivery policy can be controlled by the queue
runner settings.
