There's also sender_dependent_default_transport_maps.
http://www.postfix.org/postconf.5.html#sender_dependent_default_transport_maps

I've been using this for months, but in an external relay (not in a ZCS server a VM running postfix).
This way I don't have to deal with ZCS' upgrades or new "features".

The limit/issue with this is it's overruled by transport_map.

So if you have specific queues for some recipients (such as Orange in France - you have to talk to them very slowly) defined in the transport map, these transport rules are matching the flow before the recipient rules.
This is the way postfix works.

I haven't found a way to have both rules in the "correct" order (recipient then transport) on a single postfix instance.
