This is useless because users are stupid, people sending the mail are stupid, people getting the mail are stupid, UI people creating interfaces are so stupid society could be improved by putting them in a box and mailing them all to some wasteland and hoping they form their own society there or starve.

This would result in half the planet being frustrated all the time and the other half never getting their mail.

If your goal is to secretly destroy email this is the way.
