I think your headers are fine.  

I noticed that there was the
    Sender: Sam Varghese <samuel@gnubies.com>
header which may be added by an MTA (I think exim does this by
default) when the envelope-from is changed so that the old information
isn't lost.  

There is an 
    X-Envelope-Sender: samuel@gnubies.com
header which appears to have the same meaning as the Sender: header.

In the Received lines there is

    Received: from samuel by sammo with local (Exim 3.12 #1 (Debian))
    id 15SU5V-0004mN-00    for <debian-user@lists.debian.org>; Fri,
    03 Aug 2001 11:49:17 +1000

This says that you are user "samuel" on machine "sammo".  The MTA is
"exim" running on a Debian system.  This exists only for
administrators to track down problems with mail systems.  It is just a
record of where the message went on its way to the destination.  From
the information you gave in your first post this all looks correct and
the way it should be.

Your From: line is correct and there is no Reply-To: header to
override it so I don't see a problem with your headers.


    Received: from mrsamu.lnk.telstra.net (HELO sammo) (
    by murphy.debian.org with SMTP; Fri, 03 Aug 2001 01:49:17 +0000

header indicates that the MTA on murphy.debian.org recieved the
message from your machine (the "HELO sammo" is part of the SMTP
protocol where your machine says hello to the remote machine and gives
its name).  I guess your machine has another name that
murphy.debian.org found using reverse DNS lookup.

Your header looks like
    Mail-followup-to: debian-user@lists.debian.org
so it is correct.

I don't see that in the message I'm looking at so I don't know what it

As Colin said "L" is the "list-reply" command.  "r" replies only to
the original sender (or whoever is in the Reply-To: header if a
mailling list munges it) and "g" replies to all people in the To: and
 Cc: headers (maybe Mail-followup-to: also).
