While digging through various forums I've come across this post on the Digital Spy forums which links to a zip file of what appears to be 14659 emails from Ray Adams' computer, much more than have already been published by Austlian Financial Review.
They've been split into 4 folders, Inbox, Sent, To Ok and Deleted, and appear to represent the emails covering 1997 to 2002. While it's impossible to verfiy if these are all genuine I've spot checked some of the new emails and they do seem to be legitimate.
As News Corp has already lawyered up and taken some emails offline it's possible these files will be deleted at some point in the near future.
