Please check your assertions first.

The relevant section from the headers is:
Received: from ? ( [])
	by with ESMTPS id j2sm1257912mue.8.2008.
	(version=SSLv3 cipher=RC4-MD5); Thu, 07 Aug 2008 15:38:45 -0700 

Obviously is the internal address of the PC composing 
the message. is the external address from which the 
message was sent to using 

User-Agent: Thunderbird (X11/20080724)

The headers would have been different if the message had been posted 
using Gigglemail's web interface in the way that you did. In that 
event you correctly describe how they only list the IP Address of the 
https server presenting the web page to the user.

I know my IP address, its reverse DNS, and the IP address of my 
mailserver, and they are not the ones that I traced! I do not see my 
own ISPs address anywhere on that email.

If he is using Tiscali, or a reseller thereof, then one only has to 
look at to get a whole lot 
of (bad) news about the company.
