No, I'm afraid you're wrong. If you use -odq, no delivery hints are
generated. Each message will be independently routed and delivered. You
need -odqs if you want it to generate delivery hints while queuing. If
you use -odq, all Exim does is to put the message on the queue. Period.
I would expect -odqs to be more effective than running the queue with
-qq because it would do the initial stuff while the queueing is going
on, instead of processing the whole queue before starting to deliver it.

With -odqs you shouldn't see this. But your machine will chew up more
resources while queuing, because it will be doing routing in order to
generate the hints.
