Thanks for your response I'm not a spammer :-), i'm working in a telecom firm where we send emails to our customers. In fact, it's not easy to contact some receivers who is rate limiting, then in theses cases the goal is to reduce the rate per sec (about 10 mails per domain per sec); i'm astonished that postfix (without addons) is not allowed to do that but at best only 1 mail per domain per sec.
