Google mail Legal Notice
However, gmail does have this (http://mail.google.com/mail/help/intl/en/legal_notices.html)
"Your Intellectual Property Rights

We will not use any of your content for any purpose except to provide you with the Service."
Again, it's their 'universal terms' rubbish that scares everyone !
