Actually, in the above, the first server it hits is the external mailserver
at 24.71.223.10. I would assume anything in the 10.0.x.x block is an internal
box handling the mail load. And yes, you won't see any local host involved
from my side since I have sendmail set for SMART RELAY through my ISP.

However, the reason that you got that mail in the first place is that I used 
another mailer instead of mutt. Note the line: 

> Received:  from 192.168.0.2 ([24.70.73.190]) by l-daemon (iPlanet...

which is the envelope sender. It is still being tagged with the IP of my
FC1 box but this one does not get bounced.

Now here are the same 3 Received lines from the bounced mail when using mutt:

Received: from pd2mr4so.prod.shaw.ca
 (pd2mr4so-qfe2.prod.shaw.ca [10.0.162.107]) by l-daemon

Received: from pn2ml9so.prod.shaw.ca (pn2ml9so-qfe0.prod.shaw.ca
[10.0.121.7])

Received: from nonesuch.localdomain ([24.70.73.190])
by l-daemon (iPlanet Messaging Server 5.2 HotFix 1.18 (built Jul 28 2003))
with ESMTP id <0HRX00B4TKAQLP at l-daemon> for jbinpg at shaw.ca; Thu,
22 Jan 2004 23:49:38 -0700 (MST)
 
...and here is the reason given for the bounce:
 
MIME-version: 1.0
Content-type: text/plain; charset=us-ascii
Content-disposition: inline
User-Agent: Mutt/1.4.1i
X-Authentication-warning: nonesuch.localdomain: jb set sender to
jbinpg at shaw.ca using -f
Original-recipient: rfc822;jbinpg at shaw.ca

Somehow the local hostname of nonesuch.localdomain = 192.168.0.2 is being
tagged onto the envelope sender. Here are my relevant config lines in my
.muttrc:

set realname="Jack Bowling"
set from="jbinpg at shaw.ca"
set use_from     # create From: Header
set envelope_from       # set envelope header as well as reply-to

Yet, mails get bounced using mutt but not using another mailer. I'm at a
loss.
