Assuming that most recipients are local, use virtual_alias_domains
and virtual_alias_maps, some recipients resolving to a local email
address and some resolving remotely.
us...@example.com user1@localhost
us...@example.com user2@host.other.example

No transport map should be needed if most recipients are local.

Pick one.
- If most recipients are local, then use virtual_alias_domains
as shown above.
- If most recipients are remote. then use relay_domains
and list the remote recipients in relay_recipient_maps.
