I've decided on the alias method for the moment until I need to give
them something more flexible. Hopefully never.
For the archives I solved the previous problem by taking note of the
fatal: parameter "smtpd_recipient_restrictions": specify at least one
working instance of: check_relay_domains, reject_unauth_destination,
reject, defer or defer_if_permit

the idea being to allow everything except those addresses explicitly
listed in access.
As the configuration matures this will probably change but it does
suffice for the moment.
