> Aw hell. How many things do I have to set up just so that I can send e-mails from my own domain?

... said every spammer.

I'm sorry for your pain, and I'm in the same boat.

But it's important to understand that any sufficiently large, distributed-agent system (like federated email), will see the rise of parasites that will pump resources and diminish the value of the system.

What we're seeing here is an "immune" response to those parasites. We all pay for it.

I think this is an important lesson for anyone designing a distributed-agent system [1]. How do you design it so as to keep the bad actors out, or at least so their impact is negligeable?
