Summary: Un-classify an email message

Initial Comment:
I'm wondering if the math for adding a message
classified as ham or spam is reversible.  If it is, it
would be a nice feature to reverse the equations and
"subtract" the effect of a certain email.  For example,
if I mis-classify a message, it would be nice to
un-classify it.

I'm guessing that even if the math is close (due to
hysteresis effect??) it might be a useful feature.  But
then, I haven't looked at the code, sorry.

The pop3proxy does not currently support this behavior, though it could 
in theory.  It throws away trained messages at the moment.  This may 
change in the not-so-distant future.

The math is exactly reversible, and the underlying classifier 
has both learn() and unlearn() methods.  Whether you can get 
at them easily depends on the client you're using; for 
example, it's very easy from the project's Outlook client.
