Re: Proposed EU Directive on Electronic Commerce

To avoid the situation Piet is pointing at - mail disappear silently
because some MTA misinterpreted the headers - I would like to suggest:

    o	Place the classification in the (E)SMTP dialogue.
	"SPAM From:" is kind of nice terminology :-), but I think it
	needs to carry other parameters, like "SPAM Type: sex, money".
    
    o	Specify clearly that the response code MUST be 4xx or 5xx and
	that it MUST NOT be 2xx combined with "silently discard"
	(RFC 2119 terminolgy, not accident caps lock).

This way, mistakes will still allow legitimate mail be returned to
sender and if non-auth Relay is off at most sites we'll leave it to
the spam-friendly hosts to return (take care of) the junk.

In earlier versions of "draft-lindberg-anti-spam-mta-08.txt" some of
this was suggested, but the SMTP MTA people actually turned it down,
whether it was NIH or really bad idea I don't know.

PS
    Then there could always be an RFC 822 "X-UCE:" header with the
    same content as was in the ESMTP dialogue, just for the people
    who accepte to get everything in their mailbox and want to sort
    it into /dev/null later.
