Hello, I was wondering if anyone has succeeded to configure Postfix running on a server hosting multiple virtual domains such that outgoing mail to remote destinations get the "Return-Path" and the domain of the message-id match the "From:" header?
As it is, when sending mail, for example with a php call to mail(), the "Return path" and the domain of the message-id is always that of the hostname of the machine. (I'm running Postfix version 2.7.0 under Ubuntu 10.04) Having searched the internet quite extensively on this question, it seems a number of others have attempted this, but I didn't find any solution ... Many thanks for any help!
