I would be very, very interested in linking to this paper once it is
posted. Please let me know how it goes.

That's what I do. I've written what I believe is the only serious
open source Java mail server (I *still* can't find any other that
serves IMAP) with a variety of anti-spam technologies; currently I
use Vipul's Razor as a first pass and my own custom challenge-response
as a second pass. It also can "filter" or "proxy" IMAP/POP3
connections, for example providing an IMAP front-end to GMail.

http://mail.ibex.org/src/org/ibex/mail/protocol/
It's currently running on megacz.com:{25,119,143}.
I would really like to build in support for a hashcash style
proof-of-work and set it "on by default" for new installs provided
that:
1) The protocol is standardized, and there is a reasonable consensus
that the standard will become dominant
2) There is a good, solid, well-written, professional-looking,
*sound* rebuttal to "proof of work proves not to work" that I can
point to when people complain about spammers and zombie machines
making the whole thing pointless. Ideally it should include
calculations at least as detailed as the paper it's rebutting.
