Both alias_maps and virtual_alias_maps are destination properties, not origin properties. Adding context-dependencies to one MTA configuration makes it harder to understand. > How do I configure that?

The multi-instance README file has an example that splits a mail server into a service MTA instance that handles mail from the network, and a null MTA instance that handles local submissions from cron jobs etc. Sounds that this is what you need.
