How to make friends "Yandex mail for domain" and php mail together?

Question

PHP

There is Yandex mail for the domain, we use it to send messages manually and communicate with clients,
for example [email protected] The
task is to send notifications from the site using phpmail from our server, the option with Yandex smtp is not suitable due to restrictions on mass mailings.
How to properly configure mx, ptr and spf so that mail sent via php is considered normal, valid and does not conflict with Yandex mail.
Also, I would like the reply-to to be on the subdomain that we associated with Yandex mail. That is, php Sends a letter from the server and subscribes from [email protected], reply-to [email protected]
and we could receive answers to Yandex mail.
n.mydomain.com is already set up and configured as an alias to the mydomain.com domain in Yandex PDD.

Answer 1

At a minimum, you need to get into the DNS editor and specify your server IP address in the spf TXT record there.
For example:
@ TXT "v=spf1 ip4:78.47.136.134 a ~all"
