Well, smtpd(8) restrictions don't apply to locally submitted email.
I generally configure the default Postfix instance (that handles
local mail injection) as a null client (as in MULTI_INSTANCE_README)
and that makes it possible to use transport_mapa, and/or
default_transport to control which destinations are reachable by
adding "error:5.1.2 ..." transport overrides.
The network-facing MTA runs as a separate Postfix instance, in which
local submission is restricted:
authorized_submit_users = root, postfix
