Summary: Outlook incorrectly trains on moves messages

Initial Comment:
Consider:

* SpamBayes set to filter "inbox" and "my folder".
* Item arrives in "inbox".  SpamBayes scores as 'ham'
* Outlook rule kicks in - message moved to "My Folder"
* SpamBayes sees this message, notices we have scored
it, and assumes it is a "recover" operation - trains as
Ham.

Not sure how to tackle this!

We do remember the classification - that is how the training
is triggered.  It is *because* we remember that we do the train.

What we could do is also remember the folder we origianlly
filtered it in.  Then, when it is moved we would be able to
determine if it is being "moved back" (ie, should be
trained) or simply moved by the user (and should be ignored
- other than probably updating the name of the folder we
"trained" it in)

I should get the test case failing first.

The message database is simply a dictionary of msgid:
trained_as_spam.  No entry means "never trained", otherwise
we know how it was trained.

Couldn't you remember the classification for each message?  

This is what pop3proxy et al do - the message class provides 
the necessary information.  (This could be your chance to 
switch to using that and finish the rather uncomplete "master 
db" thing in there!) <wink>

What exactly is stored in the default_message_database 
anyway?
