Any Windows SMTP servers that can work with Socks/TOR?

[4non ym0us]

Sorry to have to ask this, I know many of you are on *nix but some of
us are stuck on Windows outside of home.

Right now unless the email is sent via webmail, going through
Tor/privocy, the receiver always see the chain of servers the email is
sent from. The last line in the chain shows the IP of the sender so
privacy is compromised.

i.e.
Received: from unknown (HELO somebody) (123.123.123.123)
  by smtp.someserver.com with SMTP; 15 Jun 2006 14:26:26 -0000

So does anybody know of any SMTP server that will work on Windows and
can be used with TOR to anonymize sent emails, i.e. recipients will
only see it as being sent from localhost or 127.0.0.1

Received: from unknown (HELO somebody) (127.0.0.1)
  by smtp.someserver.com with SMTP; 15 Jun 2006 14:26:26 -0000

Thanks!
