Unfortunately, when looking at the headers, the recipient can always see from which domain the message was actually sent because of headers like Received: and Sender:, and the envelope information. Is there a way to make it so that the recipient of a message sent from <[email protected] <mailto:[email protected]>> cannot figure out that the message was actually sent from <[email protected] <mailto:[email protected]>> when the host exim runs on has a primary hostname like mx.domain-a.net <http://mx.domain-a.net>? I´m having users who should have an email account for two domains, and when sending test messages, I can always clearly see in the headers where the messages actually came from. Do I need to set up another email server for this? I think this is where virtual hosts concept comes into play. You just need to point the MX for all domains to the very server and use virtual domains. I am a little confused though: What is rewriting the headers?
A Sender: header (besides others) is being added by exim because the From: domain does not match 'qualify_domain'. (The outgoing messages are sent by authenticated users via submission.) Now I´m looking at the documentation, trying to figure out how to disable this feature for such messages: http://www.exim.org/exim-html-current/doc/html/spec_html/ch-message_processing.html The documentation seems rather foggy in this regard. Setting 'local_from_suffix' does not help, and other related options apparently can only be used globally, though the manual indicates that the feature could somehow be disabled by the ACL. I´d probably be fine when I manage to disable adding the Sender: header.
