Re:I don't want any anonymous mail in any case. (Score 5, Interesting)

And if my inbox were a public place funded by public money, anonymous people might have a claim to using it. But my inbox is a private place funded by my money and therefore I have the right to stop people from sending to it since it costs me money to download their message.

I have the right to block phone numbers that don't display their Caller ID from calling me. People who hide their phone number are free to call anyone they want...just not me. And that's because I'm the one paying for the line. You do not get to use my line without my permission. Why should my inbox be any different?

Contrast this with my physical mailbox: I don't pay for it (directly, at least). It does not cost me money to have somebody else send me something, in general. And even COD (does anybody actually still do that?) allows me to refuse delivery if I don't want to pay. Since it is, to some degree, a public method, people can send me things without my requesting it and I have the ability to discard their messages unread. It costs me nothing.

But because I have to pay for the network connection, because I have to pay to download your message before I can determine if I want to see it, it means I get to have some control over what gets put in it.

Your right to anonymous speech does not come with a right to an audience. You do not get to enter my home, without my permission, to try to make your case. If I want to hear your speech, I will go to where you make it.
