Correction: It's a standard way to denote that "this mail is a bounce
report." Any other sort of programmatically generated email is
supposed to use an email address capable of receiving a reply so that
the sender becomes aware that it failed to be delivered. One defense
against so-called blowback spam is to refuse bounce reports which do
not, somewhere within the message, contain an email address that the
bounce recipient recently sent to.
