We have a requirement to allow only a specific from email id from a specific IP address using postfix.

I have server for mailing using postfix
i want to make configuration which generate logs like this name ECMPLOG how to configure it please help

My situation is that I want my ubuntu server with postfix to forward system mail to my email address ([email protected] as below), using mailgun as an SMTP server (forwardingdomain.com as below).

I made a mail server using **Postfix **to work with two domains: domain1.ru and domain2.ru. I registered DNS records with registrars, created mailboxes for these domains, everything works.
