Still.  The email is originating from client's IP address.  It is 
utterly unimportant what was the initial transfer protocol (SMTP or 
HTTP).  To be picky, that is what "with atom" field of Received header 
is there for.

At home, I'm a cable modem subscriber (Shaw Cable).  I'm using my ISP's 
mail server for relaying, and it will happily stick my dynamic IP 
address into Received header.  According to you, my emails should be 
blocked by anyone using any sorf of half-decent anti-spam blocking.  But 
they are not.  When I was ADSL subscriber, my former ISP (MTS) was also 
doing exactly the same thing.

I'm sorry, but you don't seem to have any valid points here.

I've just went to my private archive of Fedora mailing list, and 
examined it.

Yahoo and Hotmail do generate Received headers with "from client's IP" 
and "with HTTP" strings.  In this respect, Yahoo and Hotmail behave 
exactly the same as IMP does.

Example from Yahoo:

Received: from [24.4.75.188] by web61208.mail.yahoo.com via HTTP;
	Wed, 24 Nov 2004 21:26:06 PST

Example from Hotmail:

Received: from 66.32.118.234 by by101fd.bay101.hotmail.msn.com with HTTP;
	Mon, 13 Dec 2004 15:41:00 GMT

Gmail generates Received header "with HTTP" string, but no client IP.

So, out of the three, two are not doing what you claim they are doing.
