There are two features that support sender-dependent routing:
sender_dependent_relayhost_maps
This looks up a relayhost value that depends on sender.
Like relayhost, this uses default_transport.
It is seached with the envelope sender address and @domain.
sender_dependent_default_transport_maps
This overrides transport and destination.
It is seached with the envelope sender address and @domain.
In most cases, sender_dependent_relayhost_maps will do the job.
sender_dependent_default_transport_maps can be used to implement
quality of service for different senders.
