> alias_maps: The alias databases that are used for local(8) delivery
You can change the path for mail that is not delivered locally with
virtual_alias_maps and with transport_maps.
virtual_alias_maps changes the recipient address. Example:
search key lookup result
---------- -------------
u...@example.com u...@host.example.com
transport_maps changes the delivery agent. Example:
search key lookup result
---------- -------------
u...@example.com smtp:host.example.com
Each of these mechanisms has its uses.
