Yes, I've read this explanation, but I did not understand it. If
redirect produces an address it will simply be thrown in exim's
routing engine again, starting with the first router and not only with
the routers listed afterwards.[1]

Exim3 might behave differently.

[1] if my .forward (router #6) produces an address to root@localhost,
root@localhost will indeed be evaluated with the _earlier_ listed
router #4 (system_aliases).
