It is basically correct.
Therefore we have to pay attention to the situation where the sender doesn't
specify any Reply-To: address.
In this case the answering MUA can't find a Reply-To: field in the header so it
usually gets the From: address to send the MDN response.
This is inherently wrong as possible cause of SPAM due to the fact the From:
field is freely editable by the sender. So a better choice, in case of missing
Reply-To: address, is to get the address from the Returnpath: field.
