      The return (backward-pointing) address in the envelope is changed so that all error messages generated by the final deliveries will be returned to a list administrator, not to the message originator, who generally has no control over the contents of the list and will typically find error messages annoying.
      1. This the only difference between an SMTP alias and list; expanding recipients to RCPT commands is the same.
      1. Another great example to highlight the difference between SMTP envelope and mail data: the envelope's MAIL FROM (see annotation) is different from to the mail data's rfc822 From:.

      the reverse-path (originator) address specification command (MAIL)

      Sometimes "reverse path" or "originator" address is also referred to "backward-pointing" address (and those instances also refer to the MAIL command mostly).

      smtp rfc5321 reverse-path originator MAIL
