Question email delay

[tjyjsjj]

How can I add per-sender delays to my Postfix fix?
I installed Plesk on my VPS.
I want to send an email to a list of 200 emails with different domains.
How can I do that?

You can add default_destination_rate_delay and default_destination_concurrency_limit to /etc/postfix/main.cf but if you're going to be sending out massive emails you want to either

A) Make sure you are on a VPS service that allows you to send mass emails or
B) Use a service dedicated to sending mass emails (such as mailchimp)

default_destination_rate_delay works if the email list is the same destination domain.
I want settings that can work for per-email or per-sender delays for email list with different domains
