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.
