In the presence of a server, full access to any settings.
The problem is that when sending a letter to some recipients, I get a beat:

79.165.91.230 is my local IP, not the server

This is what was meant.
An SMTP server is running on your computer and is trying to send mail to the outside world.
But the outside world does a dul_check and sees that 79.165.91.230 has a PTR record that is customary to issue to ordinary clients, not servers.

@IlyaEvseev

Your server IP 79.165.91.230 has a ptr-record host-79-165-91-230.qwerty.ru in DNS.
Many SMTP servers believe that such a sender is a virus client computer and is trying to send spam.
Some include greylisting, but most fail immediately.
Filtering example: look for "dul_checks"

@ivanskins

the fact of the matter is that 79.165.91.230 is my local IP and not the server
is it possible to change the Received header? Or is this not the issue here?
