Is there some way to make it evident that someone has opened your email?
Hotmail could make this evident. - Force deleted messages to remain in the Trash bin for a week after receipt of the message, and display all Trashed mail in the Inbox with red strikethrough. - Record and display login ip addresses, dates, times, in the style of unix "last". Each addresses different aspects of the problem.
Right now, I can't think of anything you could do aside from suggesting that hotmail (or whoever) offer some kind of encryption service.
If you're worried about unsophisticated attackers reading your mail, why not use PGP or S/MIME? That's one of the things encryption is for. Of course that wouldn't prevent an intruder from deleting all your mail, but hopefully the sender would notice your lack of response and contact you out-of-band. Nobody should consider email a reliable communications medium these days.
