I snipped a bunch, hope that's OK, because I only wanted to remark on
the "over the open internet" part.  I don't think it's important what
the medium/network/what-have-you is, it's important that the result be
given to the originating client, probably via SMTP.  I'd even go so far
as to say that "refuse" should apply to any protocol where messages are
transported, and that SMTP is being used in the document as an example
protocol, even though it's the example that applies to the vast majority
of probable implementations.  But perhaps you can only carry
non-specificness so far.
