There are more complete answers on the Exim-users list, which I happened to
read after Mailman-users this morning.  I would still reorder the routers as
below, but the mailman_router should also select for only the domains which
contain lists.  See exim-users.

You have the routers out of order.

You don't want to be doing "local" aliasing while messages for the world are
still being considered by the routers.  mailman_router after dnslookup
should do the trick, given your router list above.
