So configure your script to send just like your regular users do.

This is reject_unauth_destination in smtpd_recipient_restrictions,
which typically would be preceded by permit_mynetworks and if using
SASL AUTH, permit_sasl_authenticated. If you have those permit_*
restrictions, neither case is being met.

No, this is wrong. The relay domain class is for when your server is
MX host for a domain, but not the final destination. This is not the
issue as you have described. You want per-client (mynetworks) or per-
user (SASL AUTH) relaying.
