Unless I misunderstand what you were trying to do, these days you'd use
sendmail's mailertable feature to do that.

Your mc file would contain

FEATURE(`mailertable')dnl

and then you could construct a mailertable per the simple syntax
described here:

I don't know Postfix or Exim well enough yet to have an opinion about
their relative merits.  Getting to know them better is on my infinitely
long to-do list though...
