What you're looking for is default_destination_rate_delay. Or you can set up a custom transport for just Hotmail related domains and set a rate delay for only those domains.

use desktop mailer instead , lot of functions

default_destination_rate_delay is for same domain.

I have tried to create a transport with regex but still it sends same time to different domains, no throttling between @msn.com and @hotmail.com, it sends to @msn and @hotmail same time, you answer is not the solution

Anyway I found a solution, nobody knows much about this simple problem and how to solve it, i searched the whole internet lol.

The solution is
Mailwizz have a delay between each email. So I set a delay in microseconds.

You didn't search hard enough. It's right there in Postfix's documentation which is probably the most extensive out there.

Example transport for Yahoo:
In master.cf

smtp_yahoo unix - - n - 3 smtp
-o syslog_name=smtp_yahoo

In main.cnf

smtp_yahoo_transport_rate_delay=??s
smtp_yahoo_destination_concurrency_limit=2 or higher, but less than the default 20

In transport_list

/@(123|456|789|abc|def|y7mail|ghi|ymail)\.com/   smtp_yahoo:
/@(jkl|mno|yahoo|yahooxtra)(\.[a-z]{2,3}){1,2}$/   smtp_yahoo:

When you monitor your mail logs, you'll see smtp_yahoo when mail is sent to Yahoo domains in transport_list and watch the delay. Why didn't you ask the question in MailWizz proper in the first place? I have an old account over there and I know for a fact that question has been asked and answered plenty of times.

I have tried this solution for some reason when I send to those two emails for example:
- ***@123
- ****@ymail.com

Its sending same time, it still saw them as different domains so postfix sent parallel.

Are you sure this should delay sending time between @123 and @ymail.com in relation to the code you posted?
Have you tested it your self?

its possible I have not tested it properly or made a mistake.
