Not surprisingly, in retrospect, the above didn't work, because the
routing decision has to be made earlier in the delivery cycle than the
stage at which the "directors" component is called up. The "smartuser"
driver is only available for director entries.
But with the above hints from Philip, it was possible to convert this
idea into router entries immediately preceding our MX overrides, as
follows:
===================
eastlondon:
driver = domainlist,
domains = "campus.ru.ac.za",
local_parts = ^e[90],
route_list = "campus.ru.ac.za dolphin.ru.ac.za";
grahamstown:
driver = domainlist,
domains = "campus.ru.ac.za",
local_parts = ^g[7890],
route_list = "campus.ru.ac.za jackal.ru.ac.za";
===================
which exhibit the desired behaviour.
