This makes me wonder: If you *do* accidentally transmit my confidential information to the wrong party, can I sue you for gross negligence? You are knowingly transmitting confidential information across an insecure network and hoping that a little block of text at the footer of the email is going to relieve you of any responsibility if it falls into the wrong hands?
Suggesting it "may be unlawful" for me to retransmit the stuff you sent me is especially egregious.
Even worse is when I see morons post to public mailing lists with such text at the bottom of their emails. After all, a Gmail or Yahoo account is *so* expensive.
P.S. - for the record, the above example email text was taken from such an email posted to a public forum, and any assertion of copyright would be countered with a textbook example of fair use doctrine.
