I am seriously suggesting that a redirect mechanism -- perhaps the email equivalent of HTPP's 301/302 -- would be worth considering.
We already have SMTP's 221 and 521 response codes for this. But because the response text is free-form there's no way to reliably parse out the new address.
Fixing this is a bit tricky since the SMTP grammar defines <Reply-line> in a way that makes it difficult to return the sort of structed response you would need.
I don't think I know the details of the law, but I would guess that "address portability" does not imply "the address you have reach is not in service. The new address is....." -- "Government big enough to supply everything you need is big enough to take everything you have." Remember: The Ark was built by amateurs, the Titanic by professionals.
