No, wait.  Perhaps I'm not making myself clear.  Let me try again:

1.  A message destined for delivery in *your* domain is fair game
    for anything you may want to do, up to and including translating
    the entire message, header and all, into Swahili.

2.  A message passing through your domain on its way to my domain
    should be left alone, without ANY modifications to the message
    AT ALL except for the envelope.

(Note that "envelope" here means the SMTP "MAIL FROM" and "RCPT TO"
values, the argument to the UUCP "rmail" command, the From_ line,
and all other things that are *NOT* covered by RFC822.)

So why shouldn't we all adopt these rules right now?  I'm listening...
