I just noticed this post at the Yahoo! group from someone asking about Google domains. The post is pretty funny if you poke around in the message headers for the X-Originating-IP and X-Yahoo-Post-IP fields and then do an RWhois reverse lookup on the IP addresses (a little trick someone taught me awhile back.) The X-Yahoo-Post-IP header is the IP address of the machine or network the post actually came from which can be awfully telling sometimes …
Anyway, just in case you need a global list of Google domain names.
