Or you could use postfwd. But in practice I don't see what the difference would be. Either way you're denying a client's connection attempts. And since anvil is part of Postfix, and in machine code, whereas postfwd is a perl policy daemon, it's must faster and more efficient. Others have very recently used smtpd_client_connection_count_limit successfully to keep legit bulk senders from hammering their queues. See the archives for the last few months.
I understand now.
