What I mean is that each mailserver is a peer in the peer-to-peer
network of mailservers, and everyone who wants to is free to operate a
mailserver, which can be implemented in free software.

An example of an anti-spam approach where this peer-to-peer nature
of email and the corresponding freedom would likely be lost is the
"pay-for-email" scheme that Bill Gates has been pushing.

Actually I run postfix myself, both for outgoing and for incoming
email; hence when you send me email, it won't go via my isp's mail
server.  But you're of course right that what you describe is the
common case.

Note that that's not the same thing as what I'm proposing.  In
my proposal, solicited email, reponses to personal email, and emails
which the recipient does not find annoying are not subject to any
artificial cost.

That kind of problem can be avoided by not giving your ISP access to
the secret key which your email program uses to sign the "this email
is considered annoying; send the money" message to the escrow server.
