When I send email via my Postfix, the header actually contains the IP
address of my laptop. Such as 192.168.1.113 [12.34.56.78]) in the
example below:
Received: from mail.origin.com (mail.origin.com [65.254.242.180])
by mail.destination.com (Postfix) with ESMTPS id 31A1B66
for <u...@destination.com>; Thu, 4 Dec 2014 21:00:36 +0100 (CET)
Received: from [192.168.1.113] (unknown [12.34.56.78])
by mail.origin.com (Postfix) with ESMTPSA id 08AE908

your client conntected to the SMTP, so it is logged and a received heaer
added, becasue, well postfix received the mail from tehre
Is it possible to disable this, or would that constitute "breaking
standards"? Is there any use in exposing my laptop IP address?
postfix don't care if it is your notebook
it add a received header for *any* client
PS: I understand that in the above example, 192.168.1.113 is a
non-routable IP. But it could be any IP, depending on the client
and you typically want to know that IP as sysadmin
others don't care at all
if you don't want to expose it configure postfix that way and the only
point where it makes sense is in the smtp-*client* realy mail outside
http://www.postfix.org/postconf.5.html#smtp_header_checks
/^Received: from .* \[192\.168\./ IGNORE
