Yes, but the issue was in confirming which email address was used in
that connection. If you assume that the remote server is replying to
the envelope header, then yes. But if you are trying to confirm that,
then you do not have enough data.
You could, of course, create your own message with known (and differing)
From, Reply-To, and envelope headers and watch the result.
