The present Postfix scheduler does not perform MX record lookups
(nor does it decide which primary and backup MX hosts to connect to).
To piggy-back deliveries for domains that share the same MX hosts,
you will need transport_map entries that do the piggy-backing for
you:
# Sites that are hosted at provider1
vanity1.example smtp:provider1
vanity2.example smtp:provider1
# Sites that are hosted at provider2
vanity3.example smtp:provider2
vanity4.example smtp:provider2
