The problem I found with that kind of an approach is that transport rules see "people" which are users, not email addresses. Any rule criteria I could find, applied to an individual user, no matter what address was used.
If you have a pre-exchange filter of some kind, (a spam solution or something else), it may have more options.

I'm thinking a transport rule where any recipient matches @old_domain and Bcc a dummy mailbox that has an auto-reply on it. Someone's going to get to log into that dummy mailbox every day and expunge the deleted messages. I've never found a way to auto-purge deleted messages.

The best answer given was to create a new user account and mailbox for each of the old addresses. Assign the old address to this "old address box". Use Out-of-office to deliver the auto-replies from these dummy boxes. I used transport rules for forward the emails from the "old address boxes" to the real email boxes by using a cc. That way the end users could see which outside users were still using the old addresses. Of course, I was lucky and I only had 9 mailboxes to stress over. If I'd had 1,000, it wouldn't have been feasible.

The time is coming to retire the previous one and we want to auto-reply to any message sent to the old domain telling people it's going away. How could a transport rule be applied to any message sent to a particular domain that Exchange is authoritative for? 'when a recipient address matches <old_domain>'?
