The only problem I see is that this would accept mail for non-existent
recipients, so you still need to specify relay_recipient_maps but the
table can be empty. The recipient address validation is then done by
virtual_alias_maps.
/etc/postfix/main.cf:
transport_maps = mapping from example.com to smtp:mailhub.example.com
relay_domains = example.com
relay_recipient_maps =
some table that can be empty.
virtual_alias_maps =
mappings from external-u...@example.com to internal-user(s)@example.com
That should do the job. Be sure to test this with a separate Postfix
instance first.
