I don't understand.
Suppose I'm a customer at a big ISP with 20 outgoing edge
servers, 19 of which are listed. Doesn't that mean that for
every mail I send, there's a 5% chance that it isn't
accredited, so big ugly dialog boxes will apear at the

There's no question that mail coming from those unlisted servers can't
be accredited. But there is still benefit in getting the other 19
listed and accrediting mail from them. Right now, there's an "all or
nothing" requirement for listing your outbound servers. "All" is
certainly the goal, but "some" is better than "none."
