Had anyone bothered to ask, I would have reported that open relay abuse

MXs are routinely probed by relay attempts: we see about 2000-4000 such
attacks each day. A similar volume of relay attempts occurs for machines
named 'mail' or 'smtp'. More obscure mail hosts might see a more
manageable number of attacks, but I still think it is valid for this draft
to state that it is best practice that MTAs must not be configured for
open relaying.
