It adds an additional bit of accountability to a mail transaction. In
particular it allows the receiving system to find out who owned the process
that connected to his system, which can be useful in a multi-user system. It
might not have been the normal MTA on the other end. A mail administrator
might want to contact a remote administrator about some mail and knowing the
owner of the process (or some token that the remote administrator can use to
identify the owner) that sent the mail might be useful.
