47.181.8.87's reverse DNS is mail.stack.loans and the router forwards its port 25 to k3m1, but nothing there accepted mail, so a provider verifying who runs the IP (Microsoft SNDS offers only postmaster@/abuse@ of that domain) could not reach anyone. postfix-k3m1-inbound listens on k3m1's host network, takes exactly those addresses to postmaster@kamocrm.com through the main postfix, and refuses everything else. It relays nothing.
