In short it can't be done with a default install of Postfix. However there are some options available to you although I don't know if they will fit your needs. The only option I know of is to limit the rate of emails sent per domain or per recipient. Check out these posts...

policyd may be able to help you out but I don't have any experience with it.

Finally check out the Postfix configuration page.
default_destination_rate_delay=20 should produce roughly the expected results.
