	The ARPAnet has a specific mechanism for designating an error
recipient; the information is passed by the SMTP mail transfer
protocol, and is kept out of the message.  The Usenet <> ARPAnet
gateway for net.emacs currently sets this to an appropriate mailbox.

	However, not all sites on the net pay attention to this data.
Due to the public inconvenience this causes, most (including the one
the message in question came from, I think) are making some effort to
fix things up.  Expecting a site which does not honor the SMTP return
address (part of the official protocol) to parse "Errors-To:" seems a
bit unreasonable...
