To deliver some address locally, you need to (surprise) specify a
destination domain name that delivers locally. That is,
1) A destination domain name that is listed in mydestination or in
virtual_mailbox_domains.
2) A destination domain name that is not subject to some wild-card
address rewrite or some routing override (transport_maps, content_filter,
etc.). If such an override exists, specify an explicit identity mapping
for the destination domain name to exclude it from the override.
