Hello.
Guys, everyone was interested in such a question as the api of mail servers is arranged.
I can send emails from any user through their api. The main thing is to set up dns records.
Now the question is how you can arrange the same from your mail server, which is on debian with exim. How do you need to configure spf and dkim, etc., so that you can send letters from any users, that is, email addresses, from your mail server?

It will not work with any, it will only work with configured domains, where the correct DNS records spf dkim dmarc will be specified.
I just don't understand what API you are talking about?
If MailForDomain - then DNS records are configured there.
If sending letters, for example, via Google, to write on behalf of Yandex mail, then the usual sending of mail through the Yandex smtp server is used there.
Like it or not, anyone who wants to send emails without my permission (DNS records) will not pass the DKIM SPF DMARC check.
