So lets see, we build a product that adheres to the IETF standard for MTA
relaying, and you call it "buggy" as a result? I don't think that's fair.

I understand your pain WRT spam, but the problem is *not* a bug, it's
adherence to the spec that defines how our product interoperates across the
Internet. And *any* mailserver that conforms to the IETF spec is
susceptible to being used as a spam relay.

What we're working on is a workaround to the problem, one that doesn't
corrupt the spec we must adhere to.
