Ah, OK, you're saying that their IPv6 isn't ready for prime time.

It has nothing to do with looking down on "subscribers" and everything
to do with practicality. When 99,9% of mail sent directly from
consumer IP ranges is botnet spam, and I think that's a reasonable
estimate, we have better things to do than to spend a lot of our money
expensively filtering that spam for the benefit of the GWL who is too
cool to relay through a mail server with a real name.
