I remember that years ago (but no longer) there was a remailer server 
somewhere in Europe that handled most of this situation. You sent it 
your message (with routing info in the message body) and it stripped 
off the identification info and headers and sent it to the desired 
destination using a new identity. All replies (and other messages to 
that identity) went back to the server which then repackaged the 
message and sent it back to you.

Of course you had to trust the remailer's operator and accept the 
fact that you were talking to it might be an exposure.
