Just doing the lookup doesn't automatically cause messages to be
rejected if the lookup fails.

Yes. But if you want to use lookup failure as a reason to reject
messages, you will need something either the helo_verify_hosts main
option (not recommended) or an ACL deny stanza to do that. RTFM for
$host_lookup_failed, helo_verify_hosts, helo_try_verify_hosts and
verify=helo.
