"jpinkerton" saked:
...
As an interesting note on this topic, my mail comes direct to my MTA
(Sendmail) on my own box, and I got a mail from my sister-in-law in Canada
with these headers (well, these relevant bits) -
Return-Path: <my_sister-in-law(_at_)ica(_dot_)net>
Received: from modus.ica.net (mail.ica.net [209.151.129.144])
by miranda.server-plant.co.uk (8.11.6/8.11.2) with ESMTP id iB4MBFW07628
for <jpinkerton(_at_)argyllnet(_dot_)co(_dot_)uk>; Sat, 4 Dec 2004 22:11:15

So, unless I am mistaken (which is always quite possible) this mail was sent
by my sister-in-law to hal (unverified [209.151.131.11] and *not* a FQDN but
presumably is her ISP) and they forwarded it to modus.ica.net before they
forwarded/resent it to my MTA (miranda.server-plant.co.uk). This forwarding
is not in my control and I don't want it to happen - so what to do?
Or am I reading these headers standing on my head? ;-)
It looks to me as if 'hal' is your sister-in-law's PC: look at the message ID.
It's almost certainly a windows machine.
So the headers seem to show a normal customer-to-ISP submission, then direct
transmission to your MTA.
