the remote server is smart-relay for your server, isn't it?
however, you can use anvil on postfix to do this
search postfix site for this vars:
in_flow_delay = 10s
smtpd_client_connection_count_limit = 5
smtpd_client_connection_rate_limit = 5
rember to apply some whitelist
smtpd_client_event_limit_exceptions = $mynetworks, etc etc
