"smtp_accept_max_per_connection" is how many messages are received in a
single connection, so varying it based on source IP and controlling it
within a single connection should be entirely doable with $acl_c_foo.
Now, implementing "smtp_accept_max_per_host" would require an external
service of some kind, yes.
It might well be better to plan to limit that too and design for your
approach from the beginning. (But I don't see the flaw in what I said).
