Use transport_maps: see "man 5 transport".
selected_address@local.domain smtp:upstream-host
recipient1@domain smtp:upstream-host
recipient2@otherdomain smtp:upstream-host
and so on.
Postfix groups recipients by next-hop destination (here:
smtp:upstream-host), subject to smtp_destination_recipient_limit.
