Correct me if I'm wrong, but it should still be possible to have a
sender-dependent lookup that happens before transport_maps or
relay_transport_maps? Indeed, I understand that no multi-key lookup
can occur, but the decision could be made first by an optional sender
lookup, then by the recipient lookup, then the default, no?
In any case, I'll likely go with a second instance of postfix for now,
but its a lot of additional complexity.
I might be off course, but wouldn't a milter cover those requirements?
