The challenge is in developing a tor extension for a mail client.  Tor is
still developing torbutton to address the changes and anonymity risks in
firefox 2 and 3.  

There once was a torbutton for thunderbird.  I think all it did was
redirect the connections to your mail servers over tor.  There are still
many personally identifing details in the mail itself that need to be
anonymized and cleaned.

And what you seem to be asking is client as a relay by default.  This
topic is discussed on the wiki at
