postfix has so much throttling control, it is not funy.  I suggest you look
into using the built-in rate limiters.  There is absolutely no reason why
your mail server should continue to accept messages from a single client if
it will go down due to the load causing problems for the other clients.

This won't do all you want, but at least it will protect your server.
