Hi. I have two questions regarding these headers: Code: Received: from example.com (unknown [127.0.0.1]) by example.com (Postfix) with ESMTP id 27EAB51F26 for <[email protected]>; Mon, 17 Nov 2008 01:13:35 +0000 (GMT) Code: Received: by example.com (Postfix, from userid 0) id 7AB7173A18; Mon, 17 Nov 2008 01:13:35 +0000 (GMT) 1) In the first one, unknown [127.0.0.1], I were wondering what is controlling it showing 127.0.0.1, I would like to use my public IP there. I know why unknown is shown, there isn't any entry for 127.0.0.1 in /etc/hosts 2) The second one, from userid 0. Isn't there any good way to skip this, except using header_checks and remove the line completely ? I don't want to remove it, just now show the "from userid". Thanks! Fannar PS. Don't ask me why I want this, its just me
