Ah. You did not say you wanted to *block* such hosts. You just said;

There are often legitimate hosts that don't have reverse lookups, so you
may end up losing real email. But if you want to do it, you can use a
statement such as
deny condition = ${if eq{$sender_host_name}{}{yes}{no}}
message = "Host name lookup failed"
in a suitable ACL.
