actually, it has been proposed before, although a IETF draft on the subject
never went anywhere so far as i know. at least some proposed legislation
has indicated that a standards body such as the IETF would be defered to if
such a standard came into being.
such banners are trivial to deploy, and some folks in the spam fighting
community deploy them despite the lack of a standard, on general
principles. for example:
220 krusty1.krusty-motorsports.com ESMTP
Exim 4.05 Wed, 14 Aug 2002 03:57:46 +0000
[ NO UCE NO UBE C=US,ST=New York ]
in the absence of a rigidly formatted banner deployed at the SMTP level,
what we're seeing in some legislation are truly harebrained ideas where
there needs to be a web page, with no defined format for specifying policy.
an actual IETF standard for a "NO UBE" smtp banner might be a good thing.
i personally would prefer NO UBE to NO UCE, as not all UCE is bad. it's
the bulk part that creates the scaling problem.
