If example.com is handled locally, then you have something accepting
mail at verification time for the non-existent address.
If you use:
exim -bt jon@???
then it should show you the redirections in a chain, with the ultimate
destination chosen for the address and the Router chosen to handle it.
That router probably is verifying inappropriately -- ie, it verifies,
but then rejects at delivery time.
If you need more debugging information:
exim -d -bt jon@???
