No need to reboot the machine. Restarting thunderbird would have been
enough were it going to have any effect at all.

In that case there's something severely b0rken with your mail system.
Take a look at the headers of this mail. You'll see that every header
makes sense because my mailer and the chain of MTAs between here and
the outside world all make sense.
First header:
Received: from dragonfly.bonivet.net (localhost [127.0.0.1])
by dragonfly.bonivet.net (8.13.6/8.13.6) with SMTP id l13DFrgu008277
for <ringzero@xxxxxxxxxxxxx>; Sat, 3 Feb 2007 13:15:53 GMT
My mailer identifies itself to the copy of sendmail running on my
workstation as "dragonfly.bonivet.net". sendmail itself sees the
connection from 127.0.0.1 as coming from "localhost" (which is pretty
much to be expected). The local MTA (sendmail 8.13.6) knows that it's
running on a machine called "dragonfly.bonivet.net".
Next header:
Received: from dragonfly.bonivet.net (dragonfly.bonivet.net [192.168.1.254])
by mail.bonivet.net (8.13.8/8.13.8) with ESMTP id l13DFuCg013787
for <ringzero@xxxxxxxxxxxxx>; Sat, 3 Feb 2007 13:15:56 GMT
The MTA running on mail.bonivet.net (sendmail 8.13.8) received the
inbound connection from a machine identifying itself as
"dragonfly.bonivet.net". The IP address from which the mail arrived was
192.168.1.254, which is registered as "dragonfly.bonivet.net" according
to my nameserver.
Next:
Received: from mail.bonivet.net (mail.bonivet.net [81.56.185.133])
(authenticated bits=0)
by vps3.bonivet.net (8.13.6.20060614/8.13.6) with ESMTP id
l13DFwRv003877
for <ringzero@xxxxxxxxxxxxx>; Sat, 3 Feb 2007 13:15:59 GMT
The MTA running on vps3.bonivet.net received an inbound connection from
a machine identifying itself "mail.bonivet.net". The IP address from
which the connection was initiated is 81.56.185.133, for which rDNS is
"mail.bonivet.net".
The chain is maintained at each link, never broken. As far as my mail
circuit is concerned, every machine identifies itself in a manner
compliant with the RFCs, down to the mailer itself, which correctly
identifies the machine on which it is running. My setup is nothing out
of the ordinary. I'm using an industry standard MTA (sendmail) and a
perfectly ordinary mail client (sylpheed).
Point is, transporting mail from A to B via any number of intermediary
machines can be achieved without difficulty and in compliance with
standards. Any software that thumbs its nose at those standards is
going to impede safe passage of your mail as spam filters are becoming
more and more strict about what they consider "valid" mail.
