The Postfix DELIVERY_rate_delay features rate-limit DELIVERIES.
None of the above attempts count towards the delivery rate limit,
because there are no email deliveries.
You need to rate-limit TCP handshakes. You will need to configure
traffic shaping inside your TCP/IP stack. The TCP stack is not part
of Postfix.
