What is the logic to choose between A and B? For example, will you have a
file which lists all the local-parts which should be sent to A, and any
local-parts not listed in that file go to B?
Anyway, probably easy enough... delivery destinations are controlled by
routers, and there's nothing to say you only have to use the domain when
making routing decisions - you can use local-parts too, or the time of day, or
the size of the message, or ...
