It sounds like you want to configure a domain in which maiil for
some users is delivered locally, while mail for others is relayed.
Typically, you'd configure the domain for remote delivery by default,
and rewrite the recipients that need local delivery.

http://www.postfix.org/postconf.5.html#relay_recipient_maps

Note that "virtual_alias_maps" applies to all recipients, not just
those in virtual_alias_domains.
