Return to Sender

Wouldn't it be nice if e-mail could be returned to its point of origin the way that most snail mail can be?

Sure, there is usually some sort of link or instructions at the end of junk e-mail which claims to remove your address from the list, but first you must open the message which might contain a virus or worm, and then more often than not the link is a dead end or "remove from list" e-mail address doesn't really exist.

If only the address of origin could be the reply-to address.

At least junk mail usually comes with a postage paid return envelope so you can send everything back to the advertiser or credit card company, and catalogs are usually quite polite about removing addresses from their mailing lists.
