But how would you configure postfix in such a way that when sending from other domains, Received by specifies exactly the domain that is in the return-path. That is, [email protected] matched the Received by domain2.com header, not domain1.com. What should be specified or commented out in main.cf? Now mydomain=domain1.com myorigin=$mydomain
