The reason this is different from v3 is that there are no longer
directors and routers. In v3, Exim *guesses* that if the end of the
directors is reached, it's "unknown local part". This is normally true.
In v4, at the end of the routers, it's no longer a good guess. All Exim
really knows is that it can't route the address.

allow_fail
data = :fail: Unknown local part
