RFC 821 and 822 were inadequate even before April 2001.

You told that *anyone who does not have an "open" email relay is in
breach of this RFC*. I'm asking you to prove it.


RFC 821          SIMPLE MAIL TRANSFER PROTOCOL           August 1982

   3.6.  RELAYING

[..]

                      ...  The receiver-SMTP may accept or reject the
      task of relaying the mail in the same way it accepts or rejects
      mail for a local user.

[..]


Just tell me *where exactly* RFC 821 enforces receiver-SMTP to accept
and deliver every message. Which part of this RFC is receiver-SMTP
breaching when it rejects to "open relay" some message?
