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.
Assuming you mean 251 and 551, the new address is in <brackets> making it straightforward to parse. There's the minor detail that nobody has, as far as I can tell, ever implemented either, but the spec's there if you want it. R's, John
