A remote delivery uses the smtp transport. All other transports are
local deliveries.

It seems to me that what you are trying to do is to create different
queues that have different processing characteristics. This is hard to
do within Exim, because it isn't designed that way.

However, you might like to think of it differently. If you had three
different boxes, you could run 3 different Exims.

Incoming messages -----> BOX 1 ---messages for X ----> BOX 2
                               |
                               ---other messages ----> BOX 3


Now you have two separate queues on BOX 2 and BOX 3 and can process them
independently. If you don't have 3 different boxes, you can of course
run 3 different versions of Exim (with different spool directories) on
the same box, using different ports, or piping using BSMTP. A bit
tricky, but it can be done.
