Your testing only covered the acceptance of mail into the spool by exim.
But your problem is onward delivery from the spool.
Run "mailq" to get a suitable id from the spool. It'll look something like
"1mGK9N-001iSK-9n".
Force a delivery attempt of this item, with debug enabled:
# exim -d+all -M <id> 2>&1 | tee log
Debug output will got to stderr, so the above captures that.
Have a read through it. You'll see info on all the work that
Exim has to do just to (try to) deliver one message...
With luck, you'll see where it goes wrong and ends up having
failed to deliver.
