> the post office should maintain an official email address for everyone.

Assuming this is a good idea, what is my email address going to look like?

Am I going to have to be xx_toast_xx@postalcustomer like at yahoo? or will it be my address ... if so, what about the other three adults who get mail at my address; do I have to change my email address when I move? Will it be my real name, but if so, what about the other hundred people with the same name as me? (Which isn't that bad, I know lots of people with a way larger highlander list) Will it just be my social security number and we can pretend duplicates don't exist?

What qualifies someone to be an everyone for this purpose?
