I've been blocking HELO as anything under my domain, as well as my IP address (as well as any bare IP addresses) for a while, and it certainly drops a fair bit. And I maintain a long list of HELO names, AND IP ranges, AND sending hostnames, AND senders domains, plus all the filtering I do after accepting the mail... Wacky.
