    The block in question reads like:

    smtpd_helo_restrictions =
            # Allow anyone on our network, by IP address.
            permit_mynetworks,
            # Now, block anyone *not* on our network who claims to be.
            check_helo_access hash:/usr/local/etc/postfix/helo_access,
            # Syntax checks
            reject_non_fqdn_hostname,
            reject_invalid_hostname,
            # Allow anyone making it so far.
            permit
