It's not an on-windows/on-linux thing. I'd probably see the same
thing if I pulled out a Windows box here, except that something about
where message-mail gets the hostname from probably arranges to insert
something more intelligent than "localhost." It's something about the
state of this machine, which is masked by my usual cable provider's
server, but is revealed where I am.
I've enclosed headers from when I send email to the same address (and
Cc myself) in the two situations.
What I notice is that when it doesn't work, the Return-Path and Sender
headers are "dave at localhost."
And note that I'm not just arbitrarily siezing on "localhost" as the
problem. This is in response to:
504 <dave at localhost>: Sender address rejected: need fully-qualified address

Hm. Most syslogs I see posted by users of other distros have the
local machine name in them.
