Revert the email footer for the moment. A few comments:
* It's using the *sending* user's UI language for the footer, which is not ideal.
* There's no clean separation between body text and footer; the text will run together unappetizingly.
* The default message is really long
* "Sent automatically" implies that it's something like a "this page changed, and the computer is notifying you", but this is an explicit user-to-user messaging action, not automatic at all.
* It's trying to take the 'allowemail' toggle string, which may contain arbitrary HTML, and pop it into a plaintext email. This can cause very ugly output if formatting or character entities are being used in the message string.
