This means: Permit all authenticated clients, reject the rest.

> smtpd_recipient_restrictions = permit, reject_unauth_destination

This means: Permit all clients.

Replace both these with:

   smtpd_recipient_restrictions =
        permit_sasl_authenticated,
        reject_unauth_destination

This means: Permit all authenticated clients, reject the rest UNLESS they
are addressed to permitted destinations (i.e. your own domains).
