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 
mail.err message

fatal: parameter "smtpd_recipient_restrictions": specify at least one 
working instance of: check_relay_domains, reject_unauth_destination, 
reject, defer or defer_if_permit

and added the following to main.cf:

smtpd_recipient_restrictions =
        check_recipient_access hash:/etc/postfix/access,

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.
