This is such a great idea that I decided to retroactively implement it on all mail systems so you can go ahead and use it today. To solve the one to many problem, the password needs to be outside of the fixed headers that are sent to everybody. This required extending the envelope which fortunately was flexible. I hope it works out for you.
