ASSP has a "Limit Number of IP addresses Per Domain (maxSMTPdomainIP
Number of Domains per IP address" parameter as well. If you look at the
spam hitting the server, you'll often see the same spam-vector IP addresses
attempting to deliver messages from different domains. Of course they'll
fail the reverse-lookup as well but it would probably still be helpful
against the worst offenders.
Just a thought.
