Also, I don't see how this helps at all on a net where there are
hundreds of thousands of open relays, all of which we assume would
have valid designated-sender records and hence be allowed to relay
spam to you.
It means that the spammer would have to use the relay's domain in the
envelope from. And that makes identify the problematic relay that
much easier.
Of course that assumes that someone who is running an open relay
would have bothered to update their DNS to support this. Not likely.
Remember. None of these non-architectural solutions are going to
solve the entire problem. I think what we should be thinking of is a
jigsaw puzzle. Can we put enough pieces in place that the entire
picture is clear--even if there are a few holes.
Okay, that was a lousy metaphor.
