Well why should it? It can but it is not mandatory. As it is for every other e-mail address. I think you are a bit confused from how mails are send at all. First there is DNS. In DNS you have usually an A record and/or an MX record. The mail server uses is to MX or A (in this order) to find the server to send mails to. That is all, MX is used for. Something completely different is a bounce or a bounce mail. A bounce is just a normal mail with two exceptions: 1. It is created by the mailserver 2. It has no sender address. (Envelope(!), nothing else is relevant for the server. However, as all other mails, it has an recipient address that is the envelope-from address of the original mail that causes that bounce.
