How do I train SpamBayes (forward/bounce method)?
Alternatively, when you receive an incorrectly classified message, you can forward it to the SMTP proxy for training. If the message should have been classified as spam, forward or bounce the message to spambayes_spam@localhost, and if the message should have been classified as ham, forward it to spambayes_ham@localhost. You can still review the training through the web interface, if you wish to do so. You should ensure that the “lookup message in cache” option is set to True/Yes before you use this. Note that some mail clients (particularly Outlook Express) do not forward all headers when you bounce, forward or redirect mail. We do not recommend using the SMTP proxy with these clients.
