The only "permit" here is for SASL authenticated users, with a final
"reject" nothing else is allowed. Plausible for an outgoing submission
server, but not for receiving inbound mail from others. Postfix is
doing exactly what you asked.
More reasonable would be:
smtpd_recipient_restrictions =
reject_unauth_destination,
reject_unauth_pipelining,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
... Perhaps a carefully chosen mainstream RBL ...
... The final "permit" is implicit, but perhaps a useful reminder ...
permit
And in master.cf, a different set of restrictions for submission,
via "-o foo=bar" overrides for all the standard restriction lists.
