In that case you should be able to replace this:

/etc/postfix/main.cf:
    transport_maps = mapping from example.com to smtp:mailhub.example.com
    relay_domains = example.com
    relay_recipient_maps = list of "good" recipients@example.com

with:

/etc/postfix/main.cf:
    transport_maps = mapping from example.com to smtp:mailhub.example.com
    relay_domains = example.com
    virtual_alias_maps =
        mappings from external-user@example.com to internal-user(s)@example.com

Unless I am missing something obvious (in which case Victor will
helpfully point out what's missing).
