Hmm, well I suppose consider this a feature request for
sender_dependent_relay_transport_maps or sender_dependent_transport_maps :)
No such feature fits into a single-key lookup design.
You're looking to exempt specific sender (domains) from the recipient-based
nexthop of specific recipient domains. This is a multi-key transport
decision, and supporting this requires a radically different design.
So the feature request is extremely unlikely to be actionable.
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.
