I mail incorrectly classified messages to two special addresses on my
mail server.  On address is for messages that should have been
classified as ham and the other is for messages that should have been
classified as spam. On the mail server, a script checks the X-Bogosity
line, then trains bogofilter with the following flags:

 -Sn -- for false positives
 -Ns -- for false negatives
 -s  -- for unsures that are spam
 -n  -- for unsures that are ham

Hope this helps,
