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

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.
Interesting - I didn't realize that the originators MUA was in the headers -
I thought is was just the MTA - which would have been the originators ISP.
But thanks for the words... :-)
Slainte,
