This  mapping overrides the default transport:nexthop selection that is
       built into Postfix:

       local_transport (default: local:$myhostname)
              This is the default for final delivery to  domains  listed  with
              mydestination,  and  for  [ipaddress]  destinations  that  match
              $inet_interfaces or $proxy_interfaces. The default nexthop  des-
              tination is the MTA hostname.

       virtual_transport (default: virtual:)
              This  is  the  default for final delivery to domains listed with
              virtual_mailbox_domains. The default nexthop destination is  the
              recipient domain.

       relay_transport (default: relay:)
              This  is  the default for remote delivery to domains listed with
              relay_domains. In order of decreasing  precedence,  the  nexthop
              destination   is   taken   from  relay_transport,  sender_depen-
              dent_relayhost_maps, relayhost, or from the recipient domain.

       default_transport (default: smtp:)
              This is the default for remote delivery to  other  destinations.
              In  order  of  decreasing precedence, the nexthop destination is
              taken       from        sender_dependent_default_transport_maps,
              default_transport,  sender_dependent_relayhost_maps,  relayhost,
              or from the recipient domain.
