If the bounce message was automatically processed by the originating e-mail program, which would file away my public key and resend the message, the entire process would be transparent to sender and receiver. It would, however, require a sender to actually generate individually encoded outgoing mail, which is not a problem for a few or a few hundred e-mails, but would be a significant burden for 100,000 outgoing e-mails. Especially compared with the current system where a single send can have a long CC list, forcing the ISP's computers to do the spammers' work.
