In main.cf:

smtpd_recipient_restrictions = permit_mynetworks
		permit_sasl_authenticated
		reject_non_fqdn_hostname
		reject_non_fqdn_sender
		check_recipient_access hash:/etc/postfix/dead
		reject_unauth_destination
		reject_rbl_client	sbl-xbl.spamhaus.org

$cat /etc/postfix/dead
dead1 at example.com		REJECT
dead2 at example.com	550	No such user.
#Long line
dead3 at example.com	550	<dead at example.com>: Recipient address rejected: User unknown in local recipient table
