I have looked into sb_smtpproxy.py source code, and found that the proxy 
examines the body part of email as well to find cached mail id. So I copied 
the original spambayes headers into the body and forwarded to the smtp 
proxy. It seemed to be working. "Could not extract id" message is not shown 
anymore. In the train_cached_message method, however, the if-statement 
prints "Could not find message...perhaps it was deleted..." (actually, I had 
to modify that line so that the strings are  concatenated first due to the 
TypeError: not all arguments converted during string formatting -- a bug.)

What's going on?

Thank you!
