I see the confusion, but the answer is "No" because MTAs work only on
envelopes. What with forwarding and aliasing, which can happen on one
machine which then sends to another machine which then fails, I don't
know how a struggling MTA can possibly decide how an envelope address
relates to one of possibly many To: (or Cc:) addresses, if at all.

If the address is the result of aliasing *on the failing host*, then
Exim does say so in the message.
