I don't want people reading the metadata either. And what is the definition of metadata? Is it just email addresses and dates or is the subject line included?

I don't want people reading the metadata either. And what is the definition of metadata? Is it just email addresses and dates or is the subject line included? Does it include any data extracted from email such as the names of other people or links to web sites? Does it just have web server IP addresses or the URLs and if the URLs does it have referrers as well. Exactly where is the line drawn? And yes El Reg is scare mongering as usual, but at least they stirred up some debate.
