Or learn how to tell people that spam is evil and under no circumstances
will you accept spam from a system that sends it out in mass volume. If an
AS became insecure and could start allowing anyone to setup new netbock
advertisements from it, you would filter out the AS. If it was small, you
might hardcode in the valid netblocks, but when it's a large AS, you tend
just to shut it all down. Such is the way with smtp.
