Then, because of services with millions of addresses, like Yahoo, they stopped doing this, and instead would bounce the messages back some time later. I recently had a conversation with a guy who's heavily involved in internet email. His view echoed what you're saying-- it does spammers a favor to bounce messages to bad addresses. But I got the impression that his view was a minority one. It sounds like you're saying his view has become the majority view. Does your job put you in a position to confirm this with authority?

The return code only tells you the local server accepted the mail. It is unlikely that server knows the address is invalid since it can only validate the domain portion of the address. Only the destination server can validate the user name, and most are now configured not to report mail sent to invalid addresses due to spam. They will silently discard the message.
