It sounds sane.

I started using fetchmail many years ago and have never really needed to
switch. So I'm still using that, (but don't necessarily recommend it to
anyone.

It seems to break the above since it delivers mail locally, so the first
headers I get are:

	X-Original-To: cworth@localhost
	Delivered-To: cworth@localhost
	Received: from yoom.home.cworth.org (yoom.home.cworth.org [127.0.0.1])
		by yoom.home.cworth.org (Postfix) with ESMTP id D391B5883A6
		for <cworth@localhost>; Mon, 12 Apr 2010 09:11:18 -0700 (PDT)
	MIME-Version: 1.0
	Received: from 10.22.226.213 [10.22.226.213]
		by yoom.home.cworth.org with IMAP (fetchmail-6.3.16)
		for <cworth@localhost> (single-drop); Mon, 12 Apr 2010 09:11:18 -0700 (PD=
T)

And none of these are useful for your detection. Worse, the presence of
"cworth.org" in the above might throw your detection off before it could
find something useful like "intel.com" in a later Received header.

I'll send a complete message with full headers to you separately.

Perhaps I can just switch programs to transfer email and avoid this
problem. Anyone have a recommendation for something to transfer mail
From=20an imap server to the local matchine, (but *not* leaving it stored
on the imap server)[*]. I don't think offlineimap supports this mode
does it?

[*] I do separately want to start playing with remote notmuch, but I
won't use this with the imap servers currently accepting my
mail. Instead, I'd rather just rsync my mail from my local machine to a
server I own, (which could then export imap if needed), and do remote
notmuch stuff from there.
